[GOLD] powerpc.cc tidies
Plus some paranoia in symval_for_branch. We shouldn't get there with
dynamic symbols, but if we ever did the static_cast to Powerpc_relobj
would be wrong.
* powerpc.cc: Use shorter equivalent elfcpp typedef for
Reltype and reloc_size throughout.
(Target_powerpc::symval_for_branch): Exclude dynamic symbols.
(Target_powerpc::Scan::local): Use local var r_sym.
(Target_powerpc::Scan::global: Likewise.
(Target_powerpc::Relocate::relocate): Delete shadowing r_sym.

Add FreeBSD/mips architecture.
This has been tested for the n64 and o32 ABIs. Signal frame unwinders for
both ABIs are provided. FreeBSD/mips requires custom linkmap offsets since
it contains an additional l_off member in 'struct link_map' that other
FreeBSD platforms do not have. Support for collecting and supplying
general purpose and floating point register sets are provided. Common
routines for working with native format register sets are exported for
use by the native target.

Fix PRU GAS for 32-bit hosts
The PRU GAS port I originally submitted does not build on 32bit hosts.
This patch fixes it by aligning md_number_to_chars's definition with
the global declaration in tc.h.
Here is the original bug report I got:
https://github.com/rcn-ee/repos/pull/23#issuecomment-269915175

Run more ld tests when not native
Many of the ld tests are not run for cross builds, in some cases
because the test needs to run a newly linked executable, and in others
simply because it was easier to write the test for native only. Even
when a test needs to run, it's good to compile and link to exercise
the linker. So that's what this patch does. I've also rid us of
the old ld_link procedure with all the HOSTING_CRT0 etc. setup. It's
much simpler to just link with $CC.
This does mean that a cross build with cross-compiler installed but
no cross C-library will give lots of failures. If that turns out to
be too annoying, I guess we can write a tcl procedure to detect it and
not run all the extra tests.

Return 'int' rather than 'unsigned short' in avrdis_opcode
avrdis_opcode return type is unsigned short, but -1 at the end of
this function is returned. Additionally, print_insn_avr doesn't
handle when -1 (in case of memory error) is returned from
avrdis_opcode.
This patch changes avrdis_opcode returning int indicating the error,
and adds a new argument for instruction we got on success. The
opcode is 16-bit, so I change local variables type to uint16_t,
and include "bfd_stdint.h" as a result. On memory error,
print_insn_avr returns -1, which is a common convention among most
of print_insn_$ARCH functions.

link_hash_copy_indirect and symbol flags
A while ago HJ fixed PR ld/18720 with commit 6e33951ed, which, among
other things, modified _bfd_elf_link_hash_copy_indirect to not copy
ref_dynamic, ref_regular, ref_regular_nonweak, non_got_ref, needs_plt
and pointer_equality_needed when setting up an indirect non-versioned
symbol pointing to a non-default versioned symbol. I didn't notice at
the time, but the pr18720 testcase fails on hppa-linux with
"internal error, aborting at binutils-gdb-2.28/bfd/elf32-hppa.c:3933
in elf32_hppa_relocate_section".
Now hppa-linux creates entries in the plt even for local functions, if
they are referenced using plabel (function pointer) relocations. So
needs_plt is set for foo when processing pr18720a.o. When the aliases
in pr28720b.o are processed, we get an indirection from foo to
foo@FOO, but don't copy needs_plt. Since foo@FOO is the "real" symbol
that is used after that point, no plt entry is made for foo and we
bomb when relocating the plabel.
As shown by the hppa-linux scenario, needs_plt should be copied even
for non-default versioned symbols. I believe all of the others ought
to be copied too, with the exception of ref_dynamic. Not copying
ref_dynamic is right because if a shared lib references "foo" it
should not be satisfied by any non-default version "foo@FOO".

copying one flag, ref_dynamic, when versioned_hidden.

dynrelro section for read-only dynamic symbols copied into executable
Variables defined in shared libraries are copied into an executable's
.bss section when code in the executable is non-PIC and thus would
require dynamic text relocations to access the variable directly in
the shared library. Recent x86 toolchains also copy variables into
the executable to gain a small speed improvement.
The problem is that if the variable was originally read-only, the copy
in .bss is writable, potentially opening a security hole. This patch
cures that problem by putting the copy in a section that becomes
read-only after ld.so relocation, provided -z relro is in force.
The patch also fixes a microblaze linker segfault on attempting to
use dynamic bss variables.

MIPS16: Simplify extended operand handling
Simplify extended operand handling and only specially process immediates
which require bit shuffling, using the generic operand insertion and

forms to be (artificially) set to 0 for their special processing to
trigger.

MIPS16/GAS: Clean up invalid unextended operand handling
Bail out right away when an unextended instruction encoding is required
either with the use of a `.t' suffix or by means of `.set noautoextend',

used.
This is to avoid messing up with the internal state of the assembler,
even though no actual failures are known to happen as a result. Add
test cases for the situation concerned.

MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

MIPS16: Remove "extended" BREAK/SDBBP handling
Remove special casing for the `6' operand code used for the embedded
trap code of the BREAK and the SDBBP instructions to support supposedly
extended forms of these instructions.
According to all versions of the MIPS16 ASE specifications these
instructions are not extensible [1][2][3][4][5][7][8][10][11], and as
from revision 2.50 of the MIPS16e ASE specifications it has been further
clarified what was previously implied, that non-extesiable instructions
when preceded with an EXTEND prefix must cause a Reserved Instruction
exception [5][6][9][10].
Therefore supposedly extended BREAK and SDBBP instructions do not serve
their purpose anymore as they do not cause a Bp and a Debug exception
respectively and supporting these forms in disassembly only causes
confusion.

Fix more cases of improper test names
I noticed more occurrences of improper test names. The rather mechanical,
tedious and large patch below addresses, hopefully, most of the leftover cases.
As usual, another pair of eyes is welcome to check if missed something or did
an invalid substitution.
This patch also fixes the prepare_for_testing calls to pass proper test names.

This stops an --enable-targets selection affecting the main target in
regards to forcing 64-bit archives. It also means mips64 and s390x

[msp430] Sync tc-msp430.c with devices.csv
This patch syncs the generated data structure in tc-msp430.c with the
latest version of devices.csv released by TI.
My understanding is that the devices being removed were "invalid spins",
so can't be being used by anyone, and never will be. Current web
searches related to these devices return no relevant results.
Built and tested (no regressions) as follows:
Configured with: --target=msp430-elf --disable-gdb
Test variations:
msp430-sim/-mcpu=msp430
msp430-sim/-mcpu=msp430x
msp430-sim/-mcpu=msp430x/-mlarge/-mdata-region=either/-mcode-region=either
msp430-sim/-mhwmult=none
msp430-sim/-mhwmult=f5series

Fix problem where version script causes predefined hidden symbol to be defined twice.
When creating a predefined hidden symbol like _GLOBAL_OFFSET_TABLE_, gold
was incorrectly letting a version script add a version to the symbol,
resulting in two copies of the symbol, both STB_LOCAL, but one of which
was grouped in the globals part of the symbol table.

Class-ify ui_out
This patch finalizes the C++ conversion of the ui-out subsystem, by
turning the ui_out and ui_out_impl structures into a single class
hierarchy. ui_out functions are turned into virtual methods of that new
class, so as a result there are a lot of call sites to update.
In the previous version of the patchset, there were separate ui_out and
ui_out_impl classes, but it wasn't really useful and added boilerplate.
In this version there is simply an ui_out base class that is
extended for CLI, TUI and MI.
It's a bit hard to maintain a ChangeLog for such a big patch, I did my
best but I'm sure there are some missing or outdated info in there...

Support aligning text section from odd addresses
Previously, the alignment directives were not correctly supported
in the text section when current alignment was only 1 byte (i.e.,
when the address was odd). Since there are no 1-byte instructions
in RISC-V, this patch resolves the bug by writing a zero byte to
obtain 2-byte alignment, at which point a 2-byte NOP can be used
to obtain 4-byte alignment.

Avoid creating symbol table entries for registers
Instructions like "jal t0, foo" were erroneously creating symbol table

be parsed as a register, rather than as a symbol.

Fix longjmp across readline w/ --enable-sjlj-exceptions toolchains
Nowadays, GDB propagates C++ exceptions across readline using
setjmp/longjmp 89525768cd08 ("Propagate GDB/C++ exceptions across
readline using sj/lj-based TRY/CATCH") because DWARF-based unwinding
can't cross C functions compiled without -fexceptions (see details
from the commit above).
Unfortunately, toolchains that use SjLj-based C++ exceptions got
broken with that fix, because _Unwind_SjLj_Unregister, which is put at
the exit of a function, is not executed due to the longjmp added by
that commit.

Fix this by making the functions involved in setjmp/longjmp as
noexcept, so that the compiler knows it doesn't need to emit the
_Unwind_SjLj_Register / _Unwind_SjLj_Unregister calls for C++
exceptions.
Tested on x86_64 Fedora 23 with:
- GCC 5.3.1 w/ DWARF-based exceptions.
- GCC 7 built with --enable-sjlj-exceptions.

Set emacs default mode for the GDB directory to C++
Since GDB has switched to C++ but the file names are still .c emacs does
not load the proper mode when opening files in the gdb directory.
This patch fixes that by enabling c++ mode.
This patch also fixes indentation tweaks as discussed in this thread:
https://sourceware.org/ml/gdb-patches/2016-12/msg00074.html
Indent with gdb-code-style.el included and the .dir-locals.el is as such:
namespace TestNameSpace {
class test
{
public:
test test() {}
int m_a;
};
struct teststruct
{
int a;
}
}
gdb/ChangeLog:
* .dir-locals.el: Set c++ mode for the directory and set indent
properly.
* gdb-code-style.el: Set c-set-offset 'innamespace as a safe value
to be used in .dir-locals.el.

MIPS16/opcodes: Respect ISA and ASE in disassembly
Limit MIPS16 instruction disassembly according to the ISA level and ASE
set selected, as with the regular MIPS and microMIPS instruction sets.
Retain the property of `objdump -m mips:16' disassembling all MIPS16
instructions however, regardless of any ISA level recorded in the binary
examined.
To validate the disassembler use the GAS test suite for its convenience
of running tests across multiple ISAs, even though placing the tests in
the binutils test suite would be more appropriate. Adjust the single
binutils test which depends on 64-bit instruction disassembly to have
the ISA level required actually recorded in the binary examined.

MIPS16: Switch to 32-bit opcode table interpretation
Switch to 32-bit MIPS16 opcode table entry interpretation, similar to
how the microMIPS opcode table is handled, for both the `match' and
`mask' fields, removing special casing for JAL and JALX instructions and
their `a' and `i' operand codes throughout, while retaining automatic
processing of extendable opcodes in assembly and disassembly.
In assembly disallow size enforcement suffixes as appropriate: `.t' for
both 32-bit instructions and macros and `.e' for macros only, making
macro handling consistent with the microMIPS instruction set.
In disassembly fully decode EXTEND prefixes prepended to unsupported
instruction encodings (according to the ISA selection) rather than
dumping them as hexadecimal data along with the following instruction,
removing all special casing for the EXTEND prefix and making its
handling rely on its opcode table entry, except where it is considered a
part of an extendable instruction.

Re-work RISC-V gas flags: now we just support -mabi and -march
We've decided to standardize on two flags for RISC-V: "-march" sets the
target architecture (which determines which instructions can be
generated), and "-mabi" sets the target ABI. We needed to rework this
because the old flag set didn't support soft-float or single-float ABIs,
and didn't support an x32-style ABI on RISC-V.
Additionally, we've changed the behavior of the -march flag: it's now a
lot stricter and only parses things we can actually understand.
Additionally, it's now lowercase-only: the rationale is that while the
RISC-V ISA manual specifies that ISA strings are case-insensitive, in
Linux-land things are usually case-sensitive. Since this flag can be
used to determine library paths, we didn't want to bake some
case-insensitivity in there that would case trouble later.
This patch implements these two new flags and removes the old flags that
could conflict with these. There wasn't a RISC-V release before, so we
want to just support a clean flag set.

Rework RISC-V relocations
Before this commit we didn't cleanly support CFI directives because the
internal offsets used to get relaxed which broke them. This patch
significantly reworks how we handle linker relaxations:
* DWARF is now properly supported
* There is a ".option norelax" to disable relaxations, for when users
write assembly that can't be relaxed (if it's to be later patched up,
for example).
* There is an additional _RELAX relocation that specifies when previous
relocations can be relaxed.
We're in the process of documenting the RISC-V ELF ABI, which will
include documentation of our relocations
https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md
but we expect that this relocation set will remain ABI compatible in the
future (ie, it's safe to release).
Thanks to Kuan-Lin Chen for figuring out how to correctly relax the
debug info!

bfd/elf32-arm.c: Rename 'popcount' to 'elf32_arm_popcount'
bfd/elf32_arm.c contains a function 'popcount' which conflicts
with a function of the same name in NetBSD's libc.
This change also changes popcount's 'sum' variable to signed
since the function returns a signed integer.
bfd/
* elf32-arm.c (elf32_arm_popcount): Rename from 'popcount'. Make
'sum' local variable signed.

MIPS/opcodes: Only call `bfd_mips_elf_get_abiflags' if BFD64
Complement commit 5e7fc731f80e ("MIPS/opcodes: Also set disassembler's
ASE flags from ELF structures") and fix an `--enable-targets=all' GDB
build regression on 32-bit hosts where the MIPS target is a secondary:
../opcodes/libopcodes.a(mips-dis.o): In function `set_default_mips_dis_options':
mips-dis.c:(.text+0x906): undefined reference to `bfd_mips_elf_get_abiflags'
collect2: error: ld returned 1 exit status
make[2]: *** [gdb] Error 1
by avoiding making a call to the `bfd_mips_elf_get_abiflags' function,
which is not available, because there is no MIPS/ELF BFD included in
32-bit BFD builds. This call is only made from a conditional code block
guarded by a check against `bfd_target_elf_flavour', which is dead in
such a configuration, however cannot be optimized away by the compiler.
Also some other MIPS BFDs may be available, such as a.out, ECOFF or PE,
so the disassembler has to remain functional.

MIPS/opcodes: Also set disassembler's ASE flags from ELF structures
Respect any ASE flags recorded in ELF file structures for the purpose of
selecting instructions to be disassembled, preventing code from being
hex-dumped even though having been clearly indicated as valid at the
assembly time. Use date from the MIPS ABI flags structure if present,
and otherwise there may be an MDMX ASE flag set in the ELF file header.
For backwards compatibility only set extra flags and do not clear any,
preserving all previously set by the architecture selected to be
disassembled for.

ld: aarch64: fix TLS relaxation where TCB_SIZE is used
TCB_SIZE is 2*sizeof(void *), which is 0x10 for lp64, and 0x8 for
ilp32. During relaxation, ld goes to do a replace:
bl __tls_get_addr => add R0, R0, TCB_SIZE
But actual implementation is:
bfd_putl32 (0x91004000, contents + rel->r_offset + 4);
Which is equivalent of add x0, x0, 0x10. This is wrong for ilp32.
The possible fix for it is:
bfd_putl32 (0x91000000 | (TCB_SIZE<<10), contents + rel->r_offset + 4);
But ilp32 also needs w-registers, so it's simpler to put proper
instruction in #if/#else condition.
There are 2 such relaxations in elfNN_aarch64_tls_relax(), and so 2 new
tests added for ilp32 mode to test it.

Fix edge cases in orphan section placement.
There were still some cases I found where orphan section placement
was screwy -- where the script has no output section description for
either .data or .bss, a .bss orphan section ends up getting placed
before the .data section. In addition, if there is an output section
description for a data section not named .data (e.g., .rela.dyn),
the orphan .bss gets placed before it. This patch cleans that up,
by tracking the last allocated section even as we're adding orphans.
I've also improved segment layout in the absence of a PHDRS clause.
A zero-length NOBITS section will no longer force a new segment
when followed by a PROGBITS section.

Fix problems with bss handling in linker scripts.
PR 16711 noted that gold allocates file space for BSS sections when using
a linker script. I've fixed that by rewriting set_section_addresses and
set_section_list_addresses to track the file offset separate from the
current virtual address, so that BSS sections do not move the file offset.
Now, if a series of BSS sections come at the end of a segment, we do not
allocate file space; but if a script forces them into the middle of a
segment, we will still allocate file space (matching Gnu ld behavior).
I've also added a warning when that happens.
That exposed another problem where orphan .bss sections were sometimes
placed in the middle of a segment. For example, if the script mentions
the .got section, but both .data and .bss are orphans, gold would put
both .data and .bss in front of .got. I've fixed that by ensuring that
orphan BSS sections are always placed after all other allocated sections.
It also exposed a problem where the SUBALIGN property is not handled
properly. The ld manual clearly states that it should override input section
alignment, whether greater or less than the given alignment, but gold would
only increase an input section's alignment. Gold would also place the output
section based on its original alignment before the SUBALIGN property took
effect, leading to a misaligned output section (where the input section
was properly aligned in memory, but was not aligned relative to the start
of the section), in violation of the ELF/gABI spec. I've fixed that by
making sure that the SUBALIGN property overrides the internal alignment of
the input sections as well as the external alignment of the output section.
This affected the behavior of script_test_2, which was written to expect
a misaligned section.
The net effect is, I think, improved compatibility with the BFD linker.
There are still cases where orphan placement differs, but the differences
should be rarer and less important. ALIGN and SUBALIGN behavior is closer,
but still not an exact match -- I still found cases where ld would create
a misaligned output section, and where gold will properly align it.

MIPS16/opcodes: Use hexadecimal interpretation for the `e' operand code
Make the `e' operand code used with raw EXTEND instructions use the
hexadecimal rather than decimal format, for consistency with what is
actually produced by code in `print_insn_mips16' dedicated to EXTEND
disassembly. Due to that special handling the operand code is only
interpreted for assembly however, which accepts either format either
way, so there is no functional change here.

The cause is that we want to access some builtin types in gdbarch init, but
it is not initialized yet. I fix it by creating the type when it is to be
used. We've already done this in sparc, sparc64 and m68k.

Add test that exercises all bfd architecture, osabi, endian, etc. combinations
This adds a test that exposes several problems fixed by earlier
patches:
#1 - Buffer overrun when host/target formats match, but sizes don't.
https://sourceware.org/ml/gdb-patches/2016-03/msg00125.html
#2 - Missing handling for FR-V FR300.
https://sourceware.org/ml/gdb-patches/2016-03/msg00117.html
#3 - BFD architectures with spaces in their names (v850).
https://sourceware.org/ml/binutils/2016-03/msg00108.html
#4 - The OS ABI names with spaces issue.
https://sourceware.org/ml/gdb-patches/2016-03/msg00116.html
#5 - Bogus HP/PA long double format.
https://sourceware.org/ml/gdb-patches/2016-03/msg00122.html
#6 - Cris big endian internal error.
https://sourceware.org/ml/gdb-patches/2016-03/msg00126.html
#7 - Several PowerPC bfd archs/machines not handled by gdb.
https://sourceware.org/bugzilla/show_bug.cgi?id=19797
And hopefully helps catch others in the future.
This started out as a test that simply did,
gdb -ex "print 1.0L"
to exercise #1 above.
Then to cover both 32-bit target / 64-bit host and the converse, I
thought of having the testcase print the floats twice, once with the
architecture set to "i386" and then to "i386:x86-64". This way it
wouldn't matter whether gdb was built as 32-bit or a 64-bit program.
Then I thought that other archs might have similar host/target
floatformat conversion issues as well. Instead of hardcoding some
architectures in the test file, I thought we could just iterate over
all bfd architectures and OS ABIs supported by the gdb build being
tested. This is what then exposed all the other problems listed
above...
With an --enable-targets=all, this exercises over 14 thousand
combinations. If left in a single test file, it all consistenly runs
in under a minute on my machine (An Intel i7-4810MQ @ 2.8 MHZ running
Fedora 23). Split in 8 chunks, as in this commit, it runs in around
25 seconds, with make -j8.
To avoid flooding the gdb.sum file, it avoids calling "pass" on each
tested combination/iteration. I'm explicitly not implementing that by
passing an empty message to gdb_test / gdb_test_multiple, because I
still want a FAIL to be logged in gdb.sum. So instead this puts the
internal passes in the gdb.log file, only, prefixed "IPASS:", for
internal pass. TBC, if some iteration fails, it'll still show up as
FAIL in gdb.sum. If this is an approach that takes on, I can see us
extending the common bits to support it for all testcases.

Compile gdb.perf/skip-prologue.c with and without debug info
gdb.perf/skip-prologue.exp is intended to measure the performance of
skipping prologue with prologue analysis by setting breakpoints.
However, if program is compiled with debug info, GDB is smart to
skip prologue by line table from debug info, so prologue analysis
is not exercised at all.
This patch adds a parameter COMPILE to specify compiling with
debug information, otherwise, it is compiled without debug
information.

Fix crash when disassembling invalid range on powerpc vle
I got a report of a gdb crash for vle and further investigation showed an
attempt to disassemble an invalid memory range. I tracked the crash down
to the code in get_powerpc_dialect, where we fail to make sure we have a
valid section pointer before dereferencing it.
There is no such problem for rs6000-based disassembling.

Follow-up to commit 14f6890677849172a4b13779acd9089c9baa3a81.

Hurd, C++: kern_return_t vs. error_t
GNU/Hurd uses its own "typedef enum __error_t_codes error_t;"
([glibc]/sysdeps/mach/hurd/bits/errno.h), contrary to the default
"typedef int error_t;" ([glibc]/stdlib/errno.h).
The Mach/Hurd RPCs return kern_return_t values, for which, upon assigning them
to an error_t variable, GCC in C++ mode tells us "error: invalid conversion
from 'kern_return_t {aka int}' to 'error_t {aka __error_t_codes}'". Instead of
casting all these RPC return values to "error_t", just use "kern_return_t"
variables:

Assert on lval_register
This patch adds asserts where the value's lval must be lval_register.
This triggers an error in frame_register_unwind because VALUE_REGNUM
is used but value's lval is not lval_register.
This also reveals a design issue in frame_register_unwind, that is
arguments addrp and realnump are mutually exclusive, we either use
addrp (for lval_memory), or use realnump (for lval_register). This
can be done in a separate patch.

PowerPC64 dot-symbol compatibility bugfixes
Lots of fixes for the compatibility code that handles linking of
-mcall-aixdesc code (or that generated by 12 year old gcc) with
current ELFv1 ABI code.
1) A reference to a dot-symbol in an object file wasn't satisfied by a
function descriptor in later object files.
2) The as-needed code had bit-rotted; Shared libs now need a strong
reference to be counted as needed.
3) --gc-sections involving dot-symbols was broken, needing
func_desc_adjust to be run early and lots of other fixes.
bfd/
* elf64-ppc.c (struct ppc_link_hash_entry): Delete "was_undefined".
(struct ppc_link_hash_table): Delete "twiddled_syms". Add
"need_func_desc_adj".

some function descriptor symbols dynamic.
(ppc64_elf_before_check_relocs): Only run add_symbol_adjust for
ELFv1. Set need_func_desc_adj. Don't fix undefs list.

Don't call lookup_fdh here.
(ppc64_elf_gc_sections): New function.
(bfd_elf64_bfd_gc_sections): Define.

(func_desc_adjust): Don't make fake function descriptor syms strong

flag when deciding whether a dynamic function descriptor might
be needed. Transfer elf.dynamic and set elf.needs_plt. Move
plt regardless of visibility. Make descriptor dynamic if
entry sym is dynamic, not for other cases.

already done.

Support an "unlimited" number of user-defined arguments
New in v2:
- A few adjustments / simplifications were possible now that we
require C++11:
. Use std::unique_ptr to make the user_args_stack std::vector own
its elements:
static std::vector<std::unique_ptr<user_args>> user_args_stack;
. use vector::emplace_back to construct elements directly in the
corresponding vectors.
. use std::to_string instead of adding a gdb::to_string
replacement.
- Now includes a test.
Docs/NEWS are unchanged from v1 and have already been approved.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I recently wrote a user-defined command that could benefit from
supporting an unlimited number of arguments:
http://palves.net/list-active-signal-handlers-with-gdb/
E.g., 'info signal-dispositions 1 2 3 4 5 6 7 8 9 10 11'
However, we currently only support up to 10 arguments passed to
user-defined commands ($arg0..$arg9).
I can't find a good reason for that, other than "old code with hard
coded limits". This patch removes that limit and modernizes the code
along the way:
- Makes the user_args struct a real C++ class that uses std::vector
for storage.
- Removes the "next" pointer from within user_args and uses a
std::vector to maintain a stack instead.
- Adds a new RAII-based scoped_user_args_level class to help
push/pop user args in the stack instead of using a cleanup.

Fix PR 20559 - "eval" command and $arg0...$arg9/$argc substitution
It'd be handy to be able to iterate over command arguments in
user-defined commands, in order to support optional arguments
($arg0..$argN).
I thought I could make it work with "eval", but alas, it doesn't work
currently. E.g., with:
define test
set $i = 0
while $i < $argc
eval "print $arg%d", $i
set $i = $i + 1
end
end
we get:
(gdb) test 1
$1 = void
(gdb) test 1 2 3
$2 = void
$3 = void
$4 = void
(gdb)
The problem is that "eval" doesn't do user-defined command arguments
substitution after expanding its own argument. This patch fixes that,
which makes the example above work:
(gdb) test 1
$1 = 1
(gdb) test 1 2 3
$2 = 1
$3 = 2
$4 = 3
(gdb)
New test included, similar the above, but also exercises expanding
$argc.
I think this is likely to simplify many scripts out there, so I'm
adding an example to the manual and mentioning it in NEWS as well.

PR symtab/16264 - support DW_AT_main_subprogram
This patch adds support for DW_AT_main_subprogram.
This is PR symtab/16264.
DW_AT_main_subprogram is used to mark a program's entry point. GCC
can emit this, and I hope to change the Rust compiler to emit it as
well.
GDB already supports an older, pre-DWARF 4 convention adopted by
FORTRAN compilers, namely to emit DW_AT_calling_convention for the
"main" function. However, I think this support in GDB had a small
bug, in that it seems to rely on the DW_AT_name being read before
DW_AT_calling_convention. This patch fixes this as well.
Built and regtested on x86-64 Fedora 24 and the buildbot. New test
case included.

Rename some trace functions
This patch renames a few trace-related functions, so that they adhere to
the de facto standard of naming command entry point functions
<command>_command. I like the ease of looking up a command entry point
if they all follow that rule.

renamed this one trace_stop_command.

Add unit test to aarch64 prologue analyzer
We don't have an effective way to test prologue analyzer which is
highly dependent on instruction patterns in prologue generated by
compiler. GDB prologue analyzer may not handle the new sequences
generated by new compiler, or may still handle some sequences that
generated by very old compilers which are no longer used. The
former is a functionality issue, while the latter is a maintenance
issue.
The input and output of prologue analyzer is quite clear, so it
fits for unit test. The input is series of instructions, and the
output are 1) where prologue end, 2) where registers are saved.
In aarch64, they are represented in 'struct aarch64_prologue_cache'.
This patch refactors aarch64_analyze_prologue so it can read
instructions from either real target or test harness. In unit
test aarch64_analyze_prologue_test, aarch64_analyze_prologue gets
instructions we prepared in the test, as the input of prologue
analyzer. Then, we checked various fields in
'struct aarch64_prologue_cache'.

Class-ify ui_out_table
This patch makes a class out of the ui_out_table structure, the
structure responsible for managing the generation of an UI table.
To simplify the ui_out_table object, I changed it so that it can only be
used for generating a single object. Instead of clearing the header
list when starting a new table, we an ui_out_table when starting a
table and delete it when we're done. Therefore, the checks:
if (uiout->table->flag)
if (!uiout->table->flag)
are respectively replaced with
if (uiout->table != nullptr)
if (uiout->table == nullptr)
Note: I removed the check at the beginning of ui_out_begin, because
there is an equivalent check at the beginning of verify_field.
New in v2:
- use "enum class" for ui_out_table::state and update references.

Simplify ui-out level code
Now that we use a vector to store the levels, we don't have to keep a
separate level field in ui_out to keep track of the current level. We
can efficiently derive it from the vector size. That causes a little
change in the meaning of the level, as in they are now 1-based instead
of 0-based (the initial level has the "id" 1 now), but it shouldn't
change anything in the behavior.
Additionally, push_level and pop_level don't really need to return the
new level, making them return void simplifies the code a bit.
Finally, the ui_out_begin/ui_out_end callbacks in the ui_out_impl
interface don't need to be passed the level, it's never actually used.
New in v2:
- Remove or update stale comments.
gdb/ChangeLog:
* ui-out.h (ui_out_begin_ftype): Remove level parameter.
(ui_out_end_ftype): Likewise.
* ui-out.c (struct ui_out) <level>: Replace field with a method
that dynamically computes the result.

(verify_field): Update access to uiout->level.
(ui_out_new): Don't initialize ui_out::level, call push_level
to push the initial level instead of doing it by hand.

Replace hand-made linked list of ui_out_hdr by vector and iterator
Instead of keeping pointers to first, last and current ui_out_hdr in
ui_out_table, we can use an std::vector and an iterator. Direct random
access of to vector helps make get_next_header a bit nicer by avoiding
iterating on all the headers. append_header_to_list is also a bit
simpler.
Also, using unique_ptr inside the vector allows expressing the ownership
of the ui_out_hdr objects by the ui_out_table object, and it simplifies
the destruction.
gdb/ChangeLog:
* ui-out.c (struct ui_out_hdr) <next>: Remove.
(struct ui_out_table) <header_first, header_last, header_next>: Remove.
<headers, headers_iterator>: New fields.

Fixup testcases outputting own name as a test name and standardize failed compilation messages
Changes in v3:
- Adjusted some testcases where the message "failed to compile" was not unique.
Changes in v2:
- Addressed comments from reviewers.
- Fixed spurious whitespaces.
- Changed compilation failure messages that included source/binary paths to
ones that are short and deterministic.
---
Another bit of cleanup to the testsuite. We have a number of tests that are
not honoring the rule of not outputting their own name as a test name.
I fixed up all the offenders i could find with the following regular
expression:
"(xfail|kfail|kpass|fail|pass|unsupported|untested) ([A-Za-z0-9]+|\\\$(.)*testfile(.)*)\.exp$"

commit bc6c7af4a2f23c48a38139fc7e0ed2ac7b12bb69

Fix test names starting with uppercase output by basic functions
The following patch is based on the previous patch i sent and handles cases of
test names that start with an uppercase letter. Test names should start with
lowercase unless it starts with the name of a technology, architecture, ISA
etc.
This first patch addresses cases of test names output explicitly via xfail,
kfail, kpass, fail, pass, unsupported, untested and also names set with the
pattern "set test" and "set testname".

Fix calculation of synthetic symbol sizes (ppc64)
The attached patch fixes a problem where nm displays bogus information for
synthetic symbol sizes when --size-sort is used.
This happens because the synthetic symbols (dot symbols for ppc64) are
generated based on their non-dot symbols. The generation process doesn't copy
over the ELF-specific bits of the regular non-dot symbols.
When --size-sort is used, the code attempts to access the symbol size from
the ELF-specific bits and ends up reading gargabe, causing the size to be
displayed incorrectly.
With the patch, i can see dot and non-dot symbols having the same size with
--size-sort.
This doesn't fix the fact that we don't display size information for synthetic
symbols without --size-sort, which i may address in the future.

Use std::string in ui_out_table
Use std::string for the id field of the ui_out_table object.
I found that all users of ui_out_table_begin passed a non-NULL value to
the tblid parameter, so we don't have to worry about the NULL case. I
changed the tblid parameter to be a std::string while at it.
gdb/ChangeLog:

std::string.

Use std::vector for cli_ui_out_data::streams
Use a standard vector instead of the home-made version. I used a vector
of plain pointers, because the cli_ui_out_data object doesn't own the

Makefiles: Disable suffix rules and implicit rules
Since we don't use suffix rules nor implicit rules in gdb, we can
disable them. The advantage is a slightly faster make [1].
Here are some numbers about the speedup. I ran this on my trusty old
Intel Q6600, so the time numbers are probably higher than what you'd get
on any recent hardware. I ran "make" in the gdb/ directory of an
already built repository (configured with --enable-targets=all). I
recorded the time of execution (average of 5). I then ran "make -d" and
recorded the number of printed lines, which gives a rough idea of the
number of operations done.
I compared the following configurations, to see the impact of both the
empty .SUFFIXES target and the empty pattern rules, as well as running
"make -r", which can be considered the "ideal" case.
A - baseline
B - baseline + .SUFFIXES
C - baseline + pattern rules
D - baseline + .SUFFIXES + pattern rules
E - baseline + make -r
config | time (s) | "make -d"
-----------------------------
A | 5.74 | 2396643
B | 1.19 | 298469
C | 2.81 | 1266573
D | 1.13 | 245489
E | 1.01 | 163914
We can see that the empty .SUFFIXES target has a bigger impact than the
empty pattern rules, but still it doesn't hurt to disable the implicit
pattern rules as well.
There are still some mentions of implicit rules I can't get rid of in
the "make -d" output. For example, it's trying to build .c files from
.w files:
Looking for an implicit rule for '/home/simark/src/binutils-gdb/gdb/infrun.c'.
Trying pattern rule with stem 'infrun'.
Trying implicit prerequisite '/home/simark/src/binutils-gdb/gdb/infrun.w'.
and trying to build Makefile.in from a bunch of extensions:
Looking for an implicit rule for 'Makefile.in'.
Trying pattern rule with stem 'Makefile.in'.
Trying implicit prerequisite 'Makefile.in.o'.
Trying pattern rule with stem 'Makefile.in'.
Trying implicit prerequisite 'Makefile.in.c'.
Trying pattern rule with stem 'Makefile.in'.
Trying implicit prerequisite 'Makefile.in.cc'.
... many more ...
If somebody knows how to disable them, we can do it, but at this point
the returns are minimal, so it is not that important.
I verified that both in-tree and out-of-tree builds work.
[1] Switching from explicit rules to pattern rules for files in
subdirectories actually made it slower, so this is kind of a way to
redeem myself. But it the end it's faster than it was previously,
so it was all worth it. :)

PR20886, looping in ppc64_elf_size_stubs
The PR20886 binary is large enough that there are two stub sections
servicing .text (which is 88M). It so happens that between one
iteration of sizing and the next that one stub section grows while
the other shrinks. Since one section is always growing, the loop
never terminates.
This patch changes the algorithm to not update previous size on
shrinking, once we go past a certain number of iterations.

Move computed value's frame id to piece_closure
Nowadays, we set computed value's frame id, which is a misuse to me.
The computed value itself doesn't care about frame id, but function
value_computed_funcs (val)->read (or read_pieced_value) cares about
which frame the register is relative to, so 'struct piece_closure' is
a better place to fit frame id.
This patch adds a frame id in 'struct piece_closure', and use it
instead of using computed value's frame id.

gas: fix CBCOND diagnostics for invalid immediate operands.
This patch fixes two problems in the SPARC assembler:
- The diagnostic message
Error: Illegal operands: Immediate value in cbcond is out of range.
is incorrectly issued for non-CBCOND instructions that feature a
simm5 immediate field, such as MPMUL, MONTMUL, etc.
- When an invalid immediate operand is used in a CBCOND
instruction, two redundant error messages are issued to the
user, the second due to a stale fixup (this happens since
commit 85024cd8bcb93f4112470ecdbd6c10fc2aea724f).
Some diagnostic tests for the CBCOND instructions are also
included in the patch.
Tested in both sparc64-linux-gnu and sparcv9-linux-gnu targets.

Optimize byte-aligned copies in copy_bitwise()
The function copy_bitwise used for copying DWARF pieces can potentially
be invoked for large chunks of data. For instance, consider a large
struct one of whose members is currently located in a register. In this
case copy_bitwise would still copy the data bitwise in a loop, which is
much slower than necessary.
This change uses memcpy for the large part instead, if possible.
gdb/ChangeLog:
* dwarf2loc.c (copy_bitwise): Use memcpy for the middle part, if
it is byte-aligned.

Fix copy_bitwise()
When the user writes or reads a variable whose location is described
with DWARF pieces (DW_OP_piece or DW_OP_bit_piece), GDB's helper
function copy_bitwise is invoked for each piece. The implementation of
this function has a bug that may result in a corrupted copy, depending
on alignment and bit size. (Full-byte copies are not affected.)
This rewrites copy_bitwise, replacing its algorithm by a fixed version,
and adding an appropriate test case. Without the fix the new test case
fails, e.g.:
print def_t
$2 = {a = 0, b = 4177919}
(gdb) FAIL: gdb.dwarf2/nonvar-access.exp: print def_t
Written in binary, the wrong result above looks like this:
01111111011111111111111
Which means that two zero bits have sneaked into the copy of the
original all-one bit pattern. The test uses this simple all-one value
in order to avoid another GDB bug that causes the DWARF piece of a
DW_OP_stack_value to be taken from the wrong end on big-endian
architectures.
gdb/ChangeLog:
* dwarf2loc.c (extract_bits_primitive): Remove.
(extract_bits): Remove.
(copy_bitwise): Rewrite. Fixes a possible corruption that may
occur for non-byte-aligned copies.
gdb/testsuite/ChangeLog:
* gdb.dwarf2/nonvar-access.exp: Add a test for accessing
non-byte-aligned bit fields.

Fix PR12616 - gdb does not implement DW_AT_data_bit_offset
The DW_AT_data_bit_offset attribute was introduced by DWARF V4 and
allows specifying the offset of a data member within its containing
entity. But although the new attribute was intended to replace
DW_AT_bit_offset for this purpose, GDB ignores it, and thus GCC still
emits DW_AT_bit_offset instead. See also
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71669.
This change fixes GDB's lack of support for DW_AT_data_bit_offset and
adds an appropriate test case.

gdb: Use C++11 std::chrono
This patch fixes a few problems with GDB's time handling.
#1 - It avoids problems with gnulib's C++ namespace support
On MinGW, the struct timeval that should be passed to gnulib's
gettimeofday replacement is incompatible with libiberty's
timeval_sub/timeval_add. That's because gnulib also replaces "struct
timeval" with its own definition, while libiberty expects the
system's.
E.g., in code like this:
gettimeofday (&prompt_ended, NULL);
timeval_sub (&prompt_delta, &prompt_ended, &prompt_started);
timeval_add (&prompt_for_continue_wait_time,
&prompt_for_continue_wait_time, &prompt_delta);
That's currently handled in gdb by not using gnulib's gettimeofday at
all (see common/gdb_sys_time.h), but that #undef hack won't work with
if/when we enable gnulib's C++ namespace support, because that mode
adds compile time warnings for uses of ::gettimeofday, which are hard
errors with -Werror.
#2 - But there's an elephant in the room: gettimeofday is not monotonic...
We're using it to:
a) check how long functions take, for performance analysis
b) compute when in the future to fire events in the event-loop
c) print debug timestamps
But that's exactly what gettimeofday is NOT meant for. Straight from
the man page:
~~~
The time returned by gettimeofday() is affected by
discontinuous jumps in the system time (e.g., if the system
administrator manually changes the system time). If you need a
monotonically increasing clock, see clock_gettime(2).
~~~
std::chrono (part of the C++11 standard library) has a monotonic clock
exactly for such purposes (std::chrono::steady_clock). This commit
switches to use that instead of gettimeofday, fixing all the issues
mentioned above.

Normalize names of some source files
Most tdep/nat files are named:
<cpu>-<os>-tdep.c
<cpu>-<os>-nat.c
A few files do not respect this scheme. This patch renames them so that
they are consistent with the rest of the files. It builds fine with
--enable-targets=all, but that doesn't test the nat files. I can only
hope that my grep skill is good enough.

Makefiles: Flatten and sort file lists
I find the big file lists in the Makefiles a bit ugly and not very
practical. Since there are multiple filenames on each line (as much as
fits in 80 columns), it's not easy to add, remove or change a name in
the middle. As a result, we have a mix of long and short lines in no
particular order (ALL_TARGET_OBS is a good example).
I therefore suggest flattening the lists (one name per line) and keeping
them in alphabetical order. The diffs will be much clearer and merge
conflicts will be easier to resolve.
A nice (IMO) side-effect I observed is that the files are compiled
alphabetically by make, so it gives a rough idea of the progress of the
build.
I added a comment in gdb/Makefile.in to mention to keep the file lists
ordered, and gave the general guidelines on what order to respect. I
added a comment in other Makefiles which refers to gdb/Makefile.in, to
avoid duplication.
Running the patch through the buildbot found that gdb.base/default.exp
started to fail. The languages in the error message shown when typing
"set language" have changed order. We could probably improve gdb so
that it prints them in a stable order, regardless of the order of the
object list passed to the linked, but just fixing the test is easier for
now.
New in v2:
- Change ordering style, directories go at the end.
- Cleanup gdbserver's and data-directory's Makefile as well.
- Add comments at top of Makefiles about the ordering.
- Remove wrong trailing backslahes.
- Fix test gdb.base/default.exp.

Delete duplicate target short-cuts to dynamic sections
We'd like to have the elf_link_hash_table srelplt field rather than
some private target field used to save short-cuts to a PLT relocation
section. This save a little space but mainly is so that the generic
ELF code can access the field. Ditto for other dynamic sections.

gas,opcodes: fix hardware capabilities bumping in the sparc assembler.
When the assembler finds an instruction which is part of a higher
opcode architecture it bumps the current opcode architecture. For
example:
$ echo "mwait" | as -bump
{standard input}: Assembler messages:
{standard input}:1: Warning: architecture bumped from "v6" to "v9m" on "mwait"
However, when two instructions pertaining to the same opcode
architecture but associated to different SPARC hardware capabilities
are found in the input stream, and no GAS architecture is specified in
the command line, the assembler bangs:
$ echo "mwait; wr %g0,%g1,%mcdper" | as -bump
{standard input}: Assembler messages:
{standard input}:1: Warning: architecture bumped from "v6" to "v9m" on "mwait"
{standard input}:1: Error: Hardware capability "sparc5" not enabled for "wr".
... and it should'nt, as WRMCDPER pertains to the same architecture
level than MWAIT.
This patch fixes this by extending the definition of sparc opcode
architectures to contain a set of hardware capabilities and making the
assembler to take these capabilities into account when updating the
set of allowed hwcaps when an architecture bump is triggered by some
instruction.
This way, hwcaps associated to architecture levels are maintained in
opcodes, while the assembler keeps the flexibiity of defining GAS
architectures including additional hwcaps (like -Asparcfmaf or the
v8plus* variants).
A test covering this failure case is included.

Create subobject value in pretty printer
Nowadays, we create a value of subobject in pretty printer with 'address'
being used,
value = value_from_contents_and_address (type, valaddr + embedded_offset,
address + embedded_offset);
set_value_component_location (value, val);
/* set_value_component_location resets the address, so we may
need to set it again. */
if (VALUE_LVAL (value) != lval_internalvar
&& VALUE_LVAL (value) != lval_internalvar_component
&& VALUE_LVAL (value) != lval_computed)
set_value_address (value, address + embedded_offset);
value_from_contents_and_address creates a value from memory, but the
value we are pretty-printing may not from memory at all.
Instead of using value_from_contents_and_address, we create a value
of subobject with the same location as object's but different offset.
We avoid using address in this way. As a result, parameter 'address'
in apply_val_pretty_printer is no longer needed, we can remove it in
next step.
We've already had the location of the 'whole' value, so it is safe
to assume we can create a value of 'component' or 'suboject' value
at the same location but with different offset.

This reverts commit b19753ce31da347605dfa903c6fd2158e2444f0d.
As it turns out, GCC (and the assembler) needs additional work in
order to support negative GOT offsets in 64-bit sparc. This is
breaking TLS Local Dynamic in position-independent code.

libiberty: Add Rust symbol demangling.
Adds Rust symbol demangler. Rust mangles symbols using GNU_V3 style,
adding a hash and various special character subtitutions. This adds
a new rust style to cplus_demangle and adds 3 helper functions
rust_demangle, rust_demangle_sym and rust_is_mangled.
rust-demangle.c was written by David. Mark did the code formatting to
GNU style and integration into the gcc/libiberty build system and
testsuite.

libiberty: demangler crash with missing :? or fold expression component.
When constructing an :? or fold expression that requires a third
expression only the first and second were explicitly checked to
not be NULL. Since the third expression is also required in these
constructs it needs to be explicitly checked and rejected when missing.
Otherwise the demangler will crash once it tries to d_print the
NULL component. Added two examples to demangle-expected of strings
that would crash before this fix.
Found by American Fuzzy Lop (afl) fuzzer.

Makefile: Replace explicit subdir rules with pattern rules
When adding a .c file in subdirectory (e.g. mi/), the current practice
is to add an explicit rule, such as:
mi-cmd-break.o: $(srcdir)/mi/mi-cmd-break.c
$(COMPILE) $(srcdir)/mi/mi-cmd-break.c
$(POSTCOMPILE)
I find it a bit verbose and cumbersome. Since we now require GNU make,
we can change those rules with pattern rules, one for each subdirectory.
For example, the following rule works for all files under mi:
%.o: $(srcdir)/mi/%.c
$(COMPILE) $<
$(POSTCOMPILE)
Those pattern rules assume that the source and target files have the
same stem (foo.c and foo.o). In one case, common-agent.o is generated
from common/agent.c, to avoid a conflict with the agent.o in gdb/. In
this case, I kept the explicit rule, which takes precedence over the
pattern rule. We could also rename common/agent.c to
common/common-agent.c to get rid of the special case and still avoid the
clash, as it is done with common/common-regcache.c, for example.
This strategy was the least intrusive I found, as it only requires
changing the rules, not the target names.
I also considered two other solutions, which I did not like because I
would have had to change target names a bit everywhere.
- Replicate the source directory structure in the build directory,
which would generate common/agent.o from common/agent.c. However,
something was not right with the dependency tracking (the .deps
directory). It's probably not hard to fix, but I did not
investigate further.
- Name the object files after the directory they are in, so that
common/agent.c would generate common_agent.c.
GDBserver can benefit from the same treatment, but I'll do it in another
patch.
Built-tested with --enable-targets=all.
New in v2:
- Regroup pattern rules for .c -> .o compilation in a single place.
- Add comment about common-agent.o.

Makefile: Replace old suffix rules with pattern rules
As mentioned here [1], suffix rules are obsolete and have been
superseeded with pattern rules. People (myself included, before writing
this patch) are more likely to know what pattern rules are than suffix
rules.
AFAIK, .SUFFIXES targets are only used for those rules, and can be
removed as well.
New in v2:
- Replace rule in gdbserver/Makefile.in as well.

Remove code that checks for GNU/non-GNU make
Since GNU make is now required to build GDB, we can remove everything
that checks whether the current make implemention is the GNU one or
not. I simply removed the @GMAKE_TRUE@ prefixes and removed the whole
lines that were prefixed with @GMAKE_FALSE@.
I removed the code in the configure scripts that set those variables.
I also removed the following bits from the configure scripts:
AC_CHECK_PROGS(MAKE, make): GNU make already defines a MAKE variable
internally to be used when invoking Makefiles recursively. I don't see
this variable being used anywhere else (in scripts for example), so I
think it's safe for removal.
AC_PROG_MAKE_SET: This macro defines a SET_MAKE output variable, which
is meant to be used in Makefiles to define the MAKE variable when
using an implementation of make that doesn't already define it.
Since we are now requiring GNU make, we don't need it anymore.
Plus, I don't see SET_MAKE being used anywhere, so I don't think it
was actually doing anything...
gdb/ChangeLog:
* Makefile.in: Remove @GMAKE_TRUE@ prefixes and removes lines
prefixed with @GMAKE_FALSE@. Update comment related to non-GNU
make.
* configure.ac: Remove checks for the make program.

Document new hard requirement on GNU make
As discussed in [1], it would be benificial for the GDB project to start
requiring GNU make to build its software. It would allow using useful
GNU-specific constructs, such as pattern rules. It would also allow
removing the alternative code paths in the Makefiles (guarded by
GMAKE_TRUE/GMAKE_FALSE), simplifying the Makefile code.

gdb/ctf.c: Get rid of mkdir redefinition
Making GDB use gnulib's C++ namespace support shows this build error

The problem is the '#define mkdir ...'
Fortunately, we can just remove it, since gnulib's sys/stat.h
replacement already takes care of the Windows mkdir prototype quirk:
~~~
/* mingw's _mkdir() function has 1 argument, but we pass 2 arguments.
Additionally, it declares _mkdir (and depending on compile flags, an
alias mkdir), only in the nonstandard includes <direct.h> and <io.h>,
which are included above. */
# if (defined _WIN32 || defined __WIN32__) && ! defined __CYGWIN__
# if !GNULIB_defined_rpl_mkdir
static int
rpl_mkdir (char const *name, mode_t mode)
{
return _mkdir (name);
}
~~~
That's sys_stat.in.h, part of the sys_stat module, which we explictly
pull in nowadays. It wasn't being pulled when this macro was added:
https://sourceware.org/ml/gdb-patches/2013-03/msg00736.html
That patch was partially reverted meanwhile here:

gdb/ada-lang.c: one malloc -> unique_ptr<[]>
Switching gdb to use gnulib's C++ namespace mode reveals we're calling
malloc instead of xmalloc here:

staging = (gdb_byte *) malloc (staging_len);
^
We're unconditionaly using the result afterwards -- so it's not a case
of gracefully handling huge allocations.
Since we want to get rid of all cleanups, fix this by switching to
new[] and unique_ptr<[]> instead, while at it.

Stash frame id of current frame before stashing frame id for previous frame
This patch ensures that the frame id for the current frame is stashed
before that of the previous frame (to the current frame).
First, it should be noted that the frame id for the current frame is
not stashed by get_current_frame(). The current frame's frame id is
lazily computed and stashed via calls to get_frame_id(). However,
it's possible for get_prev_frame() to be called without first stashing
the current frame.
The frame stash is used not only to speed up frame lookups, but
also to detect cycles. When attempting to compute the frame id
for a "previous" frame (in get_prev_frame_if_no_cycle), a cycle
is detected if the computed frame id is already in the stash.
If it should happen that a previous frame id is stashed which should
represent a cycle for the current frame, then an assertion failure
will trigger should get_frame_id() be later called to determine
the frame id for the current frame.
As of late 2016, with the "Tweak meaning of VALUE_FRAME_ID" patch in
place, this actually occurs when running the
gdb.dwarf2/dw2-dup-frame.exp test. While attempting to generate a
backtrace, the python frame filter code is invoked, leading to
frame_info_to_frame_object() (in python/py-frame.c) being called.
That function will potentially call get_prev_frame() before
get_frame_id() is called. The call to get_prev_frame() can eventually
end up in get_prev_frame_if_no_cycle() which, in turn, calls
compute_frame_id(), after which the frame id is stashed for the
previous frame.
If the frame id for the current frame is stashed, the cycle detection
code (which relies on the frame stash) in get_prev_frame_if_no_cycle()
will be triggered for a cycle starting with the current frame. If the
current frame's id is not stashed, the cycle detecting code can't
operate as designed. Instead, when get_frame_id() is called on the
current frame at some later point, the current frame's id will found
to be already in the stash, triggering an assertion failure.
Below is an in depth examination of the failure which lead to this change.
I've shortened pathnames for brevity and readability.
Here's the portion of the log file showing the failure/internal error:
(gdb) break stop_frame

at gdb/stack.c:1834
Examination of the code in frame_info_to_frame_object(), which is in
python/py-frame.c, is key to understanding this problem:
if (get_prev_frame (frame) == NULL
&& get_frame_unwind_stop_reason (frame) != UNWIND_NO_REASON
&& get_next_frame (frame) != NULL)
{
frame_obj->frame_id = get_frame_id (get_next_frame (frame));
frame_obj->frame_id_is_next = 1;
}
else
{
frame_obj->frame_id = get_frame_id (frame);
frame_obj->frame_id_is_next = 0;
}
I will first note that the frame id for frame has not been computed yet. (This
was verified by placing a breakpoint on compute_frame_id().)
The call to get_prev_frame() causes the the frame id to (eventually) be
computed for the previous frame. Here's a backtrace showing how we
get there:
#0 compute_frame_id (fi=0x10e2810)
at gdb/frame.c:496
#1 0x0000000000724a67 in get_prev_frame_if_no_cycle (this_frame=0xe5a760)
at gdb/frame.c:1871
#2 0x0000000000725136 in get_prev_frame_always_1 (this_frame=0xe5a760)
at gdb/frame.c:2045
#3 0x000000000072516b in get_prev_frame_always (this_frame=0xe5a760)
at gdb/frame.c:2061
#4 0x000000000072570f in get_prev_frame (this_frame=0xe5a760)
at gdb/frame.c:2303
#5 0x00000000004eb471 in frame_info_to_frame_object (frame=0xe5a760)
at gdb/python/py-frame.c:381
For this particular case, we end up in the else clause of the code above
which calls get_frame_id (frame). It's at this point that the frame id
for frame is computed. Again, here's a backtrace:
#0 compute_frame_id (fi=0xe5a760)
at gdb/frame.c:496
#1 0x000000000072203d in get_frame_id (fi=0xe5a760)
at gdb/frame.c:539
#2 0x00000000004eb50d in frame_info_to_frame_object (frame=0xe5a760)
at gdb/python/py-frame.c:390
The test in question, dw2-dup-frame.exp, deliberately creates a broken
(cyclic) stack. So, in this instance, the frame id for the prev
`frame' will be the same as that for `frame'. But that particular
frame id ended up in the stash during the previous frame operation.
When, just a few lines later, we compute the frame id for `frame', the
id in question is already in the stash, thus triggering the assertion
failure.
I considered two other solutions to solving this problem:
We could prevent get_prev_frame() from being called before
get_frame_id() in frame_info_to_frame_object(). (See above for the
snippet of code where this happens.) A call to get_frame_id (frame)
could be placed ahead of that code snippet above. I have tested this
approach and, while it does work, I can't be certain that
get_prev_frame() isn't called ahead of stashing the current frame
somewhere else in GDB, but in a less obvious way.
Another approach is to stash the current frame's id by calling
get_frame_id() in get_current_frame(). This approach is conceptually
simpler, but when importing a python unwinder, has the unwelcome side
effect of causing the unwinder to be called during import.
A cleaner looking fix would be to place this code after code
corresponding to the "Don't compute the frame id of the current frame
yet..." comment in get_prev_frame_if_no_cycle(). Sadly, this does not
work though; by the time we get to this point, the frame state for the
prev frame has been modified just enough to cause an internal error to
occur when attempting to compute the (current) frame id for inline
frames. (The unexpected failure count increases by roughly 130
failures.) Therefore, I decided to place it as early as possible
in get_prev_frame().
gdb/ChangeLog:
* frame.c (get_prev_frame): Stash frame id for current frame
prior to computing frame id for previous frame.

Make gdb.PendingFrame.read_register handle "user" registers.
The C function, pending_framepy_read_register(), which implements
the python interface gdb.PendingFrame.read_register does not handle
the so called "user" registers like "pc". An assertion error is
triggered due to the user registers having numbers larger than or
equal to gdbarch_num_regs(gdbarch).
With the VALUE_FRAME_ID tweak in place, the call to
get_frame_register_value() can simply be replaced by a call to
value_of_register(), which handles both real registers as well as the
user registers.
gdb/ChangeLog:
* python/py-unwind.c (pending_framepy_read_register): Use
value_of_register() instead of get_frame_register_value().

Change meaning of VALUE_FRAME_ID; rename to VALUE_NEXT_FRAME_ID
The VALUE_FRAME_ID macro provides access to a member in struct value
that's used to hold the frame id that's used when determining a
register's value or when assigning to a register. The underlying
member has a long and obscure name. I won't refer to it here, but
will simply refer to VALUE_FRAME_ID as if it's the struct value member
instead of being a convenient macro.
At the moment, without this patch in place, VALUE_FRAME_ID is set in
value_of_register_lazy() and several other locations to hold the frame
id of the frame passed to those functions.
VALUE_FRAME_ID is used in the lval_register case of
value_fetch_lazy(). To fetch the register's value, it calls
get_frame_register_value() which, in turn, calls
frame_unwind_register_value() with frame->next.
A python based unwinder may wish to determine the value of a register
or evaluate an expression containing a register. When it does this,
value_fetch_lazy() will be called under some circumstances. It will
attempt to determine the frame id associated with the frame passed to
it. In so doing, it will end up back in the frame sniffer of the very
same python unwinder that's attempting to learn the value of a
register as part of the sniffing operation. This recursion is not
desirable.
As noted above, when value_fetch_lazy() wants to fetch a register's
value, it does so (indirectly) by unwinding from frame->next.
With this in mind, a solution suggests itself: Change VALUE_FRAME_ID
to hold the frame id associated with the next frame. Then, when it
comes time to obtain the value associated with the register, we can
simply unwind from the frame corresponding to the frame id stored in
VALUE_FRAME_ID. This neatly avoids the python unwinder recursion
problem by changing when the "next" operation occurs. Instead of the
"next" operation occuring when the register value is fetched, it
occurs earlier on when assigning a frame id to VALUE_FRAME_ID.
(Thanks to Pedro for this suggestion.)
This patch implements this idea.
It builds on the patch "Distinguish sentinel frame from null frame".
Without that work in place, it's necessary to check for null_id at
several places and then obtain the sentinel frame.
It also renames most occurences of VALUE_FRAME_ID to
VALUE_NEXT_FRAME_ID to reflect the new meaning of this field.
There are several uses of VALUE_FRAME_ID which were not changed. In
each case, the original meaning of VALUE_FRAME_ID is required to get
correct results. In all but one of these uses, either
put_frame_register_bytes() or get_frame_register_bytes() is being
called with the frame value obtained from VALUE_FRAME_ID. Both of
these functions perform some unwinding by performing a "->next"
operation on the frame passed to it. If we were to use the new
VALUE_NEXT_FRAME_ID macro, this would effectively do two "->next"
operations, which is not what we want.
The VALUE_FRAME_ID macro has been redefined in terms of
VALUE_NEXT_FRAME_ID. It simply fetches the previous frame's id,
providing this id as the value of the macro.

Distinguish sentinel frame from null frame.
This patch replaces the `current_frame' static global in frame.c with
`sentinel_frame'. It also makes the sentinel frame id unique and
different from the null frame.
By itself, there is not much point to this patch, but it makes
the code cleaner for the VALUE_FRAME_ID changes in another patch.
Since we now allow "navigation" to the sentinel frame, it removes
the necessity of adding special cases to other parts of GDB.
Note that a new function, get_next_frame_sentinel_okay, is introduced
in this patch. It will be used by the VALUE_FRAME_ID changes that
I've made.
Thanks to Pedro Alves for this suggestion.

Extend test gdb.python/py-recurse-unwind.exp
This patch modifies the unwinder (sniffer) defined in
py-recurse-unwind.py so that, depending upon the value of one of its
class variables, it will take different paths through the code,
testing different functionality.
The original test attempted to obtain the value of an undefined
symbol.
This somewhat expanded test checks to see if 'pc' can be read via
gdb.PendingFrame.read_register() and also via gdb.parse_and_eval().
gdb/testsuite/ChangeLog:
* gdb.python/py-recurse-unwind.c (main): Add loop.
* gdb.python/py-recurse-unwind.py (TestUnwinder): Add calls
to read_register() and gdb.parse_and_eval(). Make each code
call a separate case that can be individually tested.
* gdb.python/py-recurse-unwind.exp (cont_and_backtrace): New
proc. Call cont_and_backtrace for each of the code paths that
we want to test in the unwinder.

Fix PR20789 - relaxation with negative valued diff relocs
Fix issues with diff relocs that have a negative value
i.e. sym2 - sym1 where sym2 is lesser than sym1.
The assembler generates a diff reloc with symbol as start of section
and addend as sym2 offset, and encodes assembly time difference at
the reloc offset.
The existing relaxation logic adjusts addends if the relaxed insn lies
between symbol and addend. That doesn't work for diff relocs where
sym2 is less than sym1 *and* the relaxed insn happens to be between
sym2 and sym1.
Fix the problems by
1. Using signed handling of the difference value (bfd_signed_vma instead
of bfd_vma, bfd_{get,set}_signed_xxx instead of bfd_{get,set}_xxx).
2. Not assuming sym2 is bigger than sym1. It instead computes the actual
addresses and sets the lower and higher addresses as start and end
addresses respectively and then sees if insn is between start and end.
3. Creating a new function elf32_avr_adjust_reloc_if_spans_insn to
centralize reloc adjustment, and ensuring diff relocs get adjusted
correctly even if their sym + addend doesn't overlap a relaxed insn.
It also removes a redundant variable did_pad. It is never set if
did_shrink is TRUE, and the code does a early return if did_shrink is
FALSE.

Delete gdb::unique_ptr/gdb::move
Now that we require C++11 and all uses of gdb::unique_ptr and
gdb::move are gone, let's remove their definitions...
With my lazy hat on, I repurposed the header for "generally useful
unique_ptr specializations", and left gdb::unique_xmalloc_ptr in

bitfield-parent-optimized-out: Fix struct definition
The "struct S" type in bitfield-parent-optimized-out.exp is declared to
have a size of 4 bytes but to hold two 4-byte members: an int-based
bitfield and a 4-byte int. Also, both members have the same
data_member_location 2, causing them to overlap and to reach 2 bytes
beyond the structure's boundary.
This is fixed by increasing the structure size to 8 and setting the
first and second member's data_member_location to 0 and 4, respectively.

btrace: read entire aux buffer
The data_head of a perf event data buffer grows indefinitely. Users are
expected to compute data_head % data_size to find the location inside the perf
event data buffer.
The aux_head of a perf event aux buffer wraps around and always stays within the
perf event aux buffer.
Well, at least that's the behaviour for BTS and PT - where BTS uses the data
buffer and PT the aux buffer.
GDB does not read beyond data_head or aux_head. This is OK for BTS but wrong
for PT. It causes only a portion of the trace to be considered by GDB. In the
extreme case, the buffer may appear (almost) empty.
Thanks to Tim Wiederhake <tim.wiederhake@intel.com> for reporting the anomaly.
Change it to read the entire aux buffer for PT. The buffer is initially zero so
any extra zeroes we read before aux_head wraps around the first time will be
ignored when searching for the first PSB packet in order to synchronize onto the
trace stream.

Use unique_xmalloc_ptr in Python code
This changes some utility functions in the Python code to return
unique_xmalloc_ptr, and then fixes up the callers.
I chose unique_xmalloc_ptr rather than std::string because at a few
call points the xmalloc'd string is released and ownership transferred
elsewhere.
This patch found a few existing memory leaks. For example,
py-unwind.c called gdbpy_obj_to_string but never freed the result.
Built and regression tested on the buildbot.

gdb/testsuite: Introduce "proc_with_prefix"
While adding new tests to gdb.base/commands.exp, I noticed that the
file includes a bunch of individual testcases split into their own
procedures, and that none have ever been adjusted to use
with_test_prefix. Instead, each gdb_test/gdb_test_multiple/etc
invocation takes care of including the procedure name in the test
message, in order to make sure test messages are unique.
Simon convinced me that using the procedure name as prefix is not that
bad of an idea:
https://sourceware.org/ml/gdb-patches/2016-10/msg00020.html
This commit adds an IMO simpler alternative to
with_test_prefix_procname added by that patch -- a new
"proc_with_prefix" convenience proc that is meant to be used in place
of "proc", and then uses it in commands.exp. Procedures defined with
this automatically run their bodies under with_test_prefix $proc_name.
Here's a sample of the resulting gdb.sum diff:
[...]
-PASS: gdb.base/commands.exp: break factorial #3
-PASS: gdb.base/commands.exp: set value to 5 in test_command_prompt_position
-PASS: gdb.base/commands.exp: if test in test_command_prompt_position
-PASS: gdb.base/commands.exp: > OK in test_command_prompt_position
+PASS: gdb.base/commands.exp: test_command_prompt_position: break factorial

agent_expr_up: gdb::unique_ptr -> std::unique_ptr

tui-winsource: Allocate for actual lines only
The logic for allocating a TUI source window's content buffer allocates
two more lines than needed, because it does not reduce the window height
by the highlight box's overhead. However, it does reduce the line width
accordingly. This patch makes the height and width calculation
consistent and improves the comment.
gdb/ChangeLog:
* tui/tui-winsource.c (tui_alloc_source_buffer): Subtract
highlight box's overhead when calculating the content height.

tui-disasm: Fix line buffer size calculation
The code that fills the TUI disassembly window content first calculates
the maximum full length of a displayed disassembly line. This
calculation typically yields the wrong result. The result is too large,
so the bug does not cause any run-time failures, but unnecessary
confusion for the reader. This patch fixes the calculation.
gdb/ChangeLog:
* tui/tui-disasm.c (tui_set_disassem_content): Fix calculation of
the longest disassembly line's length.

tui-disasm: Fix window content buffer overrun
A user reported a GDB crash with TUI when trying to debug a function
with a long demangled C++ method name. It turned out that the logic for
displaying the TUI disassembly window has a bug that can cause a buffer
overrun, possibly overwriting GDB-internal data structures. In
particular, the logic performs an unguarded strcpy.
Another (harmless) bug in tui_alloc_source_buffer causes the buffer to
be two lines longer than needed. This may have made the crash appear
less frequently.
gdb/ChangeLog:
* tui/tui-disasm.c (tui_set_disassem_content): Fix line buffer
overrun due to unchecked strcpy.
gdb/testsuite/ChangeLog:
* gdb.base/tui-layout.c: New file.
* gdb.base/tui-layout.exp: Use tui-layout.c, to ensure that the
disassembly window contains very long lines.

Fix some error-handling bugs in python frame filters
While writing a Python frame filter, I found a few bugs in the current
frame filter code. In particular:
* One spot converts a Python long to a CORE_ADDR using PyLong_AsLong.
However, this can fail on overflow. I changed this to use
get_addr_from_python.
* Another spot is doing the same but with PyLong_AsUnsignedLongLong; I
changed this as well just for consistency.
* Converting line numbers can print "-1" if conversion from long
fails. This isn't fatal but just a bit ugly.
I've included a test case for the first issue. The line number one
didn't seem important enough to bother with.

Remove parameter valaddr from la_val_print
Nowadays, we pass both val and return value of
value_contents_for_printing (val) to la_val_print. The latter is
unnecessary. This patch removes the second parameter of la_val_print,
and get valaddr in each language's implementation by calling
value_contents_for_printing. Since value_contents_for_printing calls
value_fetch_lazy, I also make VAL non-const.
Note that
- I don't clean up the valaddr usages in each language's routines,
- I don't remove valaddr from apply_ext_lang_val_pretty_printer, and
extension language ops apply_val_pretty_printer.
They can be done in followup patches.

Use get_frame_register_value instead of deprecated_frame_register_read
This patch calls get_frame_register_value instead of
deprecated_frame_register_read, so that we can pass
value_contents_for_printing to val_print. Both
get_frame_register_value and deprecated_frame_register_read call
frame_unwind_register_value indirectly, so no functionality is changed

Eliminate agent_expr_p; VEC -> std::vector in struct bp_target_info
After the previous patch, we end up with these two types with quite
similar, and potentially confusing names:
typedef gdb::unique_ptr<agent_expr> agent_expr_up;
/* Pointer to an agent_expr structure. */
typedef struct agent_expr *agent_expr_p;
The latter is only necessary to put agent_expr pointers in VECs. So
just eliminate it and use std::vector instead.

'struct agent_expr *' -> unique_ptr<agent_expr>
This patch makes the gen_* functions return a unique_ptr instead of
raw pointer:
typedef gdb::unique_ptr<agent_expr> agent_expr_up;

make_cleanup_free_agent_expr.
The cond_bytecode and cmd_bytecode fields of struct bp_location are

Use ui_file_as_string throughout more
This replaces most of the remaining ui_file_xstrdup calls with
ui_file_as_string calls. Whenever a call was replaced, that led to a
cascade of other necessary adjustments throughout, to make the code
use std::string instead of raw pointers. And then whenever I added a
std::string as member of a struct, I needed to adjust
allocation/destruction of said struct to use new/delete instead of
xmalloc/xfree.
The stopping point was once gdb built again. These doesn't seem to be
a way to reasonably split this out further.
Maybe-not-obvious changes:
- demangle_for_lookup returns a cleanup today. To get rid of that,
and avoid unnecessary string dupping/copying, this introduces a
demangle_result_storage type that the caller instantiates and
passes to demangle_for_lookup.
- Many methods returned a "char *" to indicate that the caller owns
the memory and must free it. Those are switched to return a
std::string instead. Methods that return a "view" into some
internal string return a "const char *" instead. I.e., we only
copy/allocate when necessary.

Use ui_file_as_string in gdb/compile/
Using ui_file_as_string would imply changing a few prototypes to pass
around source and object file names as std::string. Instead of that,
wrap those two in a new class. This ends up eliminating a small
wrinkle: get_new_file_names and compile_object_load have swapped
parameters. The former takes "source, objfile", while the latter
takes "objfile, source".

Clean up tracepoint.h/c:collection_list
Noticed we could do this while working on the expression_up change.
The main goal here was getting rid of the
encode_actions_and_make_cleanup / do_clear_collection_list cleanups.
While at it, uncrustify the code:
- Make collection_list a C++ class, with data members private (and
thus renamed m_...).
- Make related functions be member methods.
- Use std::vector instead of an open coding a vector implementation.
- Use std::sort instead of qsort.
- Rename the "list" member of collection_list, which is an incredibly
obfuscating name.
- Rename a couple other things here and there for clarify.
- Use "bool" more.

Introduce ui_file_as_string
ui_file_as_string is a variant of ui_file_xstrdup that returns a
std::string instead of a xmalloc'ed char *. The idea is using the new
function to eliminate "make_cleanup (xfree, ...)" cleanups
throughout.
Following patches will make use of this.

'struct expression *' -> gdb::unique_xmalloc_ptr<expression>
This patch makes parse_expression and friends return a unique_ptr
instead of raw pointer [1]:
typedef gdb::unique_malloc_ptr<expression> expression_up;
and then adjusts the codebase throughout to stop using cleanups to
manage lifetime of expression pointers.
Whenever I found a structure owning an expression pointer, I made it
store a unique_ptr instead of a raw pointer, which then requires using
new/delete of the holding structure, instead of XNEW/xfree.
[1] - I'd like to set the rule that types named with an "_up" suffix
are unique_ptr typedefs.
Note I used gdb::unique_xmalloc_ptr instead of gdb::unique_ptr, simply
because we still use xmalloc instead of new to allocate expression
objects. Once that's changed, all we need to do is change the
expression_up typedef and the smart pointer will then call delete
instead of xfree.

breakpoint.c:commands_command_1 constification and cleanup
This is constification needed for next patch. Adjust
commands_command_1 to use std::string too because the "arg" parameter
is currently overwritten and then passed to make_cleanup. The
constification alone would trigger a compile error in the make_cleanup
call otherwise (passing const char * to void * parameter). Using
std::string gets rid of the cleanup in the first place, resulting in
simpler code.

Check for truncated registers in process_g_packet
While investigating an unrelated issue in remote.c I noticed that the
bound checking for 'g' packets was bogus:
The previous code would only check that the first byte of the register
was within bounds before passing the buffer to regcache_raw_supply.
If it turned out that the register in the 'g' packet was incomplete
then regcache_raw_supply would proceed to memcpy out-of-bounds.
Since the buffer is allocated with alloca it's relatively unlikely to
crash (you just end up dumping gdb's stack into the cache) but it's
still a bit messy.
I changed this logic to check for truncated registers and raise an
error if one is encountered. Hopefully it should make debugging
remote stubs a bit easier.

arc/nps400: Validate address type operands correctly
When we match against an address type operand within an instruction it
is important that we match exactly the right address type operand early
on, during the opcode selection phase. If we wait until the operand
insertion phase to check that we have the correct address operand, then
it is too late to select an alternative opcode. This becomes important
only when we have multiple opcodes with the same mnemonic, and operand
lists that differ only in the type of the address operands.
This commit fixes this issue, and adds some example instructions that
require this issue to be fixed (the instructions are identical except
for the address type operand).

set default-directory in dwarf-browse
I've been using dwarf-mode.el again recently and I found it mildly
annoying that the mode doesn't set default-directory. Setting it
means that operations in the dwarf-browsing buffer default to the
directory holding the object file being investigated.
This bumps the version number as well so that updating it via the
package manager works properly.

ld: Allow EXCLUDE_FILE to be used outside of the section list
Currently the EXCLUDE_FILE linker script construct can only be used
within the input section list, and applied only to the section pattern
immediately following the EXCLUDE_FILE. For example:
*.o (EXCLUDE_FILE (a.o) .text .rodata)
In this case all sections matching '.text' are included from all files
matching '*.o' but not from the file 'a.o'. All sections matching
'.rodata' are also included from all files matching '*.o' (incluing from
'a.o').
If the user wants to restrict the inclusion of section '.rodata' so that
this too is not taken from the file 'a.o' then the above example must be
extended like this:
*.o (EXCLUDE_FILE (a.o) .text EXCLUDE_FILE (a.o) .rodata)
However, due to the internal grammar of the linker script language the
snippet 'EXCLUDE_FILE (a.o) .text' is parsed by a pattern called
'wildcard_spec'. The same 'wildcard_spec' pattern is also used to parse
the input file name snippet '*.o' in the above examples. As a result of
this pattern reuse within the linker script grammar then the following
is also a valid linker script construct:
EXCLUDE_FILE (a.o) *.o (.text .rodata)
However, though the linker accepts this without complaint the
EXCLUDE_FILE part is silently ignored and has no effect.
This commit takes this last example and makes it a useful, valid,
construct. The last example now means to include sections '.text' and
'.rodata' from all files matching '*.o' except for the file 'a.o'.
If the list of input sections is long, and the user knows that the file
exclusion applies across the list then the second form might be a
clearer alternative to replicating the EXCLUDE_FILE construct.
I've added a set of tests for EXCLUDE_FILE to the linker, including
tests for the new functionality.

ld: Create test object files based on source file name
When creating object files during testing, base the name of the object
file on the name of the source file, rather than using dump0.o,
dump1.o, etc. There's a few places where we have multiple source
files with the same name but in different directories, in these cases,
even after this change, we still add a numerical suffix to make the
object file names unique. So if we have 'foo/src.s' and 'bar/src.s',
we will create object files 'src.o' and 'src1.o'.
Update the few tests that hard code the object file name into the
expected test results.

[ARC] Fix ldbit test on 32-bit systems
The long immediate operand chosen for one of the ldbit tests is
equivalent to a small negative value that would fit inside an s9
operand, leading to the assembler to choose an unexpected (but
legitimate) encoding of the instruction on 32-bit systems, and
therefore causing the test to fail. This commit fixes the test by
changing the offending limm value so that it can no longer be
interpreted as an s9 operand.
gas/ChangeLog:
* testsuite/gas/arc/nps400-6.s: Change ldbit tests so that
limm operands are out of the range of an s9, in order to fix
the test.

arc: Change max instruction length to 64-bits
The current handling for arc instructions longer than 32-bits is all
handled as a special case in both the assembler and disassembler.
The problem with this approach is that it leads to code duplication,
selecting a long instruction is exactly the same process as selecting a
short instruction, except over more bits, in both cases we select based
on bit comparison, and initial operand insertion and extraction.
This commit unifies both the long and short instruction worlds,
converting the core opcodes library from being largely 32-bit focused,
to being largely 64-bit focused.
The changes are, on the whole, not too much. There's obviously a lot of
type changes but otherwise the bulk of the code just works. Most of the
actual functional changes are to code that previously handled the longer
48 or 64 bit instructions. The insert/extract handlers for these have
now been brought into line with the short instruction insert/extract
handlers.
All of the special case handling code that was previously added has now
been removed again. Overall, this commit reduces the amount of code in
the arc assembler and disassembler.

Remove GDBARCH_BREAKPOINT_MANIPULATION and SET_GDBARCH_BREAKPOINT_MANIPULATION
Both of them are used in conversion. We can remove them since the
conversion is done.
There are many architectures only have one breakpoint instruction,
so their gdbarch methods breakpoint_kind_from_pc and
sw_breakpoint_from_kind look very similar. Instead of macro, we
use template "template <size_t, const gdb_byte *> struct bp_manipulation"
for these architectures. In order to use template, I also change
breakpoint instruction of type "static const gdb_byte[]" to
"constexpr gdb_byte[]", and rename them to ARCH_break_insn.

New gdbarch methods breakpoint_kind_from_pc and sw_breakpoint_from_kind
This patch adds two gdbarch methods breakpoint_kind_from_pc and
sw_breakpoint_from_kind, and uses target_info.placed_size as "kind"
of the breakpoint. This patch updates the usages of
target_info.placed_size.
The "kind" of a breakpoint is determined by gdbarch rather than
target, so we have gdbarch method breakpoint_kind_from_pc, and we
should set target_info.placed_size out of each implementation of
target to_insert_breakpoint. In this way, each target doesn't have
to set target_info.placed_size any more.
This patch also sets target_info.placed_address before
target_insert_breakpoint too, so that target to_insert_breakpoint
can use it, see record_full_insert_breakpoint.
Before we call target_insert_breakpoint, we set
target_info.placed_address and target_info.placed_size like this,
CORE_ADDR addr = bl->target_info.reqstd_address;
bl->target_info.placed_size = gdbarch_breakpoint_kind_from_pc (bl->gdbarch, &addr);
bl->target_info.placed_address = addr;
return target_insert_breakpoint (bl->gdbarch, &bl->target_info);
target_insert_breakpoint may fail, but it doesn't matter to the "kind"
and "placed_address" of a breakpoint. They should be determined by
gdbarch.

gdbarch_breakpoint_from_pc doesn't return NULL
gdbarch_breakpoint_from_pc doesn't return NULL except for
ia64_breakpoint_from_pc, and we checked its return value in three
places. In microblaze_linux_memory_remove_breakpoint and
ppc_linux_memory_remove_breakpoint, gdbarch_breakpoint_from_pc never
returns NULL, so we can remove the NULL checking. In
default_memory_insert_breakpoint, gdbarch_breakpoint_from_pc can't
returns NULL too because ia64 defines its own memory_insert_breakpoint.

Fix dwarf_expr_context method regressions
This fixes some regressions found in the patch to convert
dwarf_expr_context to use methods. Specifically:
* get_base_type could erroneously throw; this was rewritten to move
the size checks into the only spot needing them.
* Previously the "symbol needs frame" implementation reused th
"cfa" function for the get_frame_pc slot; this reimplements
it under the correct name.
* Not enough members were saved and restored in one implementation
of push_dwarf_reg_entry_value; this patch fixes this oversight
and also takes the opportunity to remove an extraneous structure
definition.

BFD: Fix double BFD_FAIL calls in `bfd_default_reloc_type_lookup'
Break out of the outer switch statement once the inner switch for the
BFD_RELOC_CTOR relocation has been processed, preventing double BFD_FAIL
calls from being made, once from the inner switch and then again from
the default case of the outer switch.
Noticed with a `-Wimplicit-fallthrough' build error reported by a recent
GCC version:
In file included from .../bfd/reloc.c:52:0:

gdb/doc: Remove mention of vCont's default actions
Discussion with qemu folks suggests that the vCont description could
be even simpler and clearer. Given we now say:
For each inferior thread, the leftmost action with a matching
thread-id is applied.
There's really no need to even talk about "default" actions, which
raises doubts about whether "default" is special in some way (it's
not).

gdb: Require C++11
Use AX_CXX_COMPILE_STDCXX to detect if the compiler supports C++11,
and if -std=xxx switches are necessary to enable C++11.
We need to tweak AX_CXX_COMPILE_STDCXX a bit though. Pristine
upstream AX_CXX_COMPILE_STDCXX appends -std=gnu++11 to CXX directly.
That doesn't work for us, because the top level Makefile passes CXX
down to subdirs, and that overrides whatever gdb/Makefile may set CXX
to. The result would be that a make invocation from the build/gdb/
directory would use "g++ -std=gnu++11" as expected, while a make
invocation at the top level would not.
So instead of having AX_CXX_COMPILE_STDCXX set CXX directly, tweak it
to AC_SUBST a separate variable -- CXX_DIALECT -- and use '$(CXX)
(CXX_DIALECT)' to compile/link.
Confirmed that this enables C++11 starting with gcc 4.8, the first gcc
release with full C++11 support.
Also confirmed that configure errors out gracefully with older GCC
releases:
checking whether /opt/gcc-4.7/bin/g++ supports C++11 features by default... no
checking whether /opt/gcc-4.7/bin/g++ supports C++11 features with -std=gnu++11... no
checking whether /opt/gcc-4.7/bin/g++ supports C++11 features with -std=gnu++0x... no
checking whether /opt/gcc-4.7/bin/g++ supports C++11 features with -std=c++11... no
checking whether /opt/gcc-4.7/bin/g++ supports C++11 features with -std=c++0x... no
checking whether /opt/gcc-4.7/bin/g++ supports C++11 features with +std=c++11... no
checking whether /opt/gcc-4.7/bin/g++ supports C++11 features with -h std=c++11... no
configure: error: *** A compiler with support for C++11 language features is required.
Makefile:9451: recipe for target 'configure-gdb' failed
make[1]: *** [configure-gdb] Error 1
make[1]: Leaving directory '/home/pedro/brno/pedro/gdb/mygit/cxx-convertion/build-gcc-4.7'
If we need to revert back to making C++11 optional, all that's
necessary is to change the "mandatory" to "optional" in configure.ac
and regenerate configure (both gdb and gdbserver).

gdb: Import AX_CXX_COMPILE_STDCXX from the GNU Autoconf Archive
This macro throws C++11 code at the compiler in order to check whether
it supports C++11. final/override, rvalue references, static_assert,
decltype, auto, constexpr, etc., and adds -std=gnu++11 to CXX if
necessary.
Nothing uses the macro yet. Simply adding it as separate preliminary
step because we'll need local changes.

gdb/testsuite: Avoid a buffer overrun in `gdb.base/maint.exp'
Fixes:
PASS: gdb.base/maint.exp: maint w/o args
ERROR: internal buffer is full.
UNRESOLVED: gdb.base/maint.exp: maint info line-table w/o a file name
The problem is just many symtabs and long line tables, enough to
overflow the expect buffer. Fix this by matching input incrementally.
gdb/testsuite/ChangeLog:
2016-10-28 Pedro Alves <palves@redhat.com>
* gdb.base/maint.exp <maint info line-table w/o a file name>: Use
gdb_test_multiple, tighten regexps and match symtabs and line
tables incrementally.

Make gdb.base/foll-exec.exp test pattern more general
Testing a powerpc toolchain running gdbserver on the other end i noticed a
failure in gdb.base/foll-exec.exp. Turns out gdb is outputting a slightly
different pattern due to the presence of debug information.
--
foll-exec is about to execlp(execd-prog)...^M
Continuing.^M
process 21222 is executing new program: gdb.d/outputs/gdb.base/foll-exec/execd-prog^M
^M
Catchpoint 2 (exec'd gdb.d/outputs/gdb.base/foll-exec/execd-prog), _start () at ../sysdeps/powerpc/powerpc32/dl-start.S:32^M
--
Notice the presence of source file information.
Now, on my local machine, i get this:
--
foll-exec is about to execlp(execd-prog)...^M
Continuing.^M
process 9285 is executing new program: gdb/testsuite/outputs/gdb.base/foll-exec/execd-prog^M

--
So the output differs slightly and the testcase is actually expecting only
the second form with the "in" anchor.
This patch removes the "in" pattern and lets the test match both kinds of
output.

Fix gdb.base/maint.exp regressions
This commit fixes these regressions:
FAIL: gdb.base/maint.exp: mt set per on for expand-symtabs
FAIL: gdb.base/maint.exp: maint set per-command on
caused by commit 1e3b796d58ac ("Change command stats reporting to use
class").
gdb.log shows that the command stats are now printing garbage:
(gdb) mt set per on
Command execution time: -6.-419590 (cpu), 1467139648.-7706296840 (wall)
Space used: 9809920 (-33276528 for this command)
(gdb) FAIL: gdb.base/maint.exp: mt set per on for expand-symtabs
while there should have been no output at all.
The stats printing is done from within the scoped_command_stats's
destructor, depending on whether some flags in the object are set.
The problem is simply that scoped_command_stats's ctor misses clearing
those flags on some paths.
Since scoped_command_stats objects are allocated on the stack, whether
you'll see the regression simply depends on whatever happens to
already be on the stack space the object occupies.
gdb/ChangeLog:
2016-10-28 Pedro Alves <palves@redhat.com>
* maint.c (scoped_command_stats::scoped_command_stats): Clear

btrace: bridge gaps
Most of the time, the trace should be in one piece. This case is handled fine
by GDB. In some cases, however, there may be gaps in the trace. They result
from trace decode errors or from overflows.
A gap in the trace means we lost an unknown amount of trace. Gaps can be very
small, such as a few instructions in the same function, or they can be rather
big. We may, for example, lose a few function calls or returns. The trace may
continue in a different function and we likely don't know how we got there.
Even though we can't say how the program executed across a gap, higher levels
may not be impacted too much by it. Let's assume we have functions a-e and a
trace that looks roughly like this:
a
\
b b
\ /
c <gap> c
/
d d
\ /
e
Even though we can't say for sure, it is likely that b and c are the same
function instance before and after the gap. This patch is trying to connect
the c and b function segments across the gap.
This will add a to the back trace of b on the right hand side. The changes are
reflected in GDB's internal representation of the trace and will improve:
- the output of "record function-call-history /c"
- the output of "backtrace" in replay mode
- source stepping in replay mode
will be improved indirectly via the improved back trace
I don't have an automated test for this patch; decode errors will be fixed and
overflows occur sporadically and are quite rare. I tested it by hacking GDB to
provoke a decode error and on the expected gap in the gdb.btrace/dlopen.exp
test.
The issue is that we can't predict where we will be able to re-sync in case of
errors. For the expected decode error in gdb.btrace/dlopen.exp, for example, we
may be able to re-sync somewhere in dlclose, in test, in main, or not at all.
Here's one example run of gdb.btrace/dlopen.exp with and without this patch.

It worked nicely in this case but it may, of course, also lead to weird
connections; it is a heuristic, after all.
It works best when the gap is small and the trace pieces are long.

btrace: preserve function level for unexpected returns
When encountering a return for which we have not seen a corresponding call, GDB
starts a new back trace from level -1, i.e. from the level of the first function
in the trace.
In the presence of trace gaps, this may cause some rather big jump.
(gdb) record function-call-history /c 192, +8
192 sbrk
193 brk
194 __x86.get_pc_thunk.bx
195 brk
196 __kernel_vsyscall
197 [disabled]
198 __kernel_vsyscall
199 brk
200 sbrk
This doesn't help to make things more clear. Let's remain on the same level
instead.
(gdb) record function-call-history /c 192, +8
192 sbrk
193 brk
194 __x86.get_pc_thunk.bx
195 brk
196 __kernel_vsyscall
197 [disabled]
198 __kernel_vsyscall
199 brk
200 sbrk
In this case it will look like we were able to connect the trace parts across
the disabled gap. We were not. More work is required to achieve this.
In the general case, the function-call history for the two trace parts won't
match. They may be off by a few levels or they may be entirely different. All
this patch does is to preserve the indentation level of the record
function-call-history command.
The disabled gap is caused by a sysenter not returning to the next instruction.

I've seen this on 32-bit Fedora 23. I have not investigated what causes this
and whether we can avoid the gap in the first place. Let's first try to make
GDB handle such gaps more gracefully.

btrace: update tail call heuristic
An unconditional jump to the start of a function typically indicates a tail
call.
If we can't determine the start of the function at the destination address, we
used to treat it as a tail call, as well. This results in lots of tail calls
for code for which we don't have symbol information.
Restrict the heuristic to only consider jumps as tail calls that switch
functions in the case where we can't determine the start of a function. This
effectively disables tail call detection for code without symbol information.

btrace: allow leading trace gaps
GDB ignores trace gaps from decode errors or overflows at the beginning of the
trace. There isn't really a gap in the trace; the trace just starts a bit

In cases where there is no trace at all or where the trace is smaller than
expected, this may hide the reason for the missing trace.
Allow leading trace gaps. They will be shown as decode warnings and by the
record function-call-history command.

Also add a warning when decoding the trace and print the instruction number
preceding the trace gap in that warning message. It looks like this:

Get pending events in random
Nowadays, we select events to be reported to GDB in random, however
that is not enough when many GDBserver internal events (not reported
to GDB) are generated.
GDBserver pulls all events out of kernel via waitpid, and leave them
pending. When goes through threads which have pending events,
GDBserver uses find_inferior to find the first thread which has
pending event, and consumes it. Note that find_inferior always
iterate threads in a fixed order. If multiple threads keep hitting
GDBserver breakpoints, range stepping with single-step breakpoint for
example, threads in the head of the thread list are more likely to be
processed and threads in the tail are starved. This causes some timeout
fails in gdb.threads/non-stop-fair-events.exp when range stepping is
enabled on arm-linux.
This patch fixes this issue by randomly selecting pending events. It
adds a new function find_inferior_in_random, which iterates threads
which have pending events randomly.

gas/arc: Don't rely on bfd list of cpu type for cpu selection
In the ARC assembler, when a cpu type is specified using the .cpu
directive, we rely on the bfd list of arc machine types in order to
validate the cpu name passed in.
This validation is only used in order to check that the cpu type passed
to the .cpu directive matches any machine type selected earlier on the
command line. Once that initial check has passed a full check is
performed using the assemblers internal list of know cpu types.
The problem is that the assembler knows about more cpu types than bfd,
some cpu types known by the assembler are actually aliases for a base
cpu type plus a specific set of assembler extensions. One such example
is NPS400, though more could be added later.
This commit removes the need for the assembler to use the bfd list of
machine types for validation. Instead the error checking, to ensure
that any value passed to a '.cpu' directive matches any earlier command
line selection, is moved into the function arc_select_cpu.
I have taken the opportunity to bundle the 4 separate static globals
that describe the currently selected machine type into a single
structure (called selected_cpu).

PR 20569, segv in follow_exec
The following testcases make GDB crash whenever an invalid sysroot is
provided, when GDB is unable to find a valid path to the symbol file:
gdb.base/catch-syscall.exp
gdb.base/execl-update-breakpoints.exp
gdb.base/foll-exec-mode.exp
gdb.base/foll-exec.exp

gdb.threads/non-ldr-exc-2.exp
gdb.threads/non-ldr-exc-3.exp
gdb.threads/non-ldr-exc-4.exp
gdb.threads/thread-execl.exp
The immediate cause of the segv is that follow_exec is passing a NULL
argument (the result of exec_file_find) to strlen.
However, the problem is deeper than that: follow_exec simply isn't
prepared for the case where sysroot translation fails to locate the
new executable. Actually all callers of exec_file_find have bugs due
to confusion between host and target pathnames. This commit attempts
to fix all that.
In terms of the testcases that were formerly segv'ing, GDB now prints
a warning but continues execution of the new program, so that the
tests now mostly FAIL instead. You could argue the FAILs are due to a
legitimate problem with the test environment setting up the sysroot
translation incorrectly.
A new representative test is added which exercises the ne wwarning
code path even with native testing.
Tested on x86_64 Fedora 23, native and gdbserver.

Make symfile_add_flags and objfile->flags strongly typed
This makes these flag types be "enum flag" types. The benefit is
making use of C++'s stronger typing -- mixing the flags types by
mistake errors at compile time.
This caught one old bug in symbol_file_add_main_1 already, fixed by
this patch as well:
@@ -1318,7 +1326,7 @@ symbol_file_add_main_1 (const char *args, int from_tty, int flags)

- if ((flags & SYMFILE_NO_READ) == 0)
+ if ((add_flags & SYMFILE_NO_READ) == 0)
set_initial_language ();
}
Above, "flags" are objfile flags, not symfile_add_flags. So that was
actually checking for "flag & OBJF_PSYMTABS_READ", which has the same
value as SYMFILE_NO_READ...
I moved the flags definitions to separate files to break circular

gdb: Coalesce/aggregate (async) vCont packets/actions
Currently, with "maint set target-non-stop on", that is, when gdb
connects with the non-stop/asynchronous variant of the remote
protocol, even with "set non-stop off", GDB always sends one vCont
packet per thread resumed. This patch makes GDB aggregate and
coalesce vCont packets, so we send vCont packets like "vCont;s:p1.1;c"
in non-stop mode too.
Basically, this is done by:
- Adding a new target method target_commit_resume that is called
after calling target_resume one or more times. When resuming a
batch of threads, we'll only call target_commit_resume once after
calling target_resume for all threads.
- Making the remote target defer sending the actual vCont packet to
target_commit_resume.
Special care must be taken to avoid sending a vCont action with a
"wildcard" thread-id (all threads of process / all threads) when that
would resume threads/processes that should not be resumed. See
remote_commit_resume comments for details.
Unlike all-stop's remote_resume implementation, this handles the case
of too many actions resulting in a too-big vCont packet, by flushing
the vCont packet and starting a new one.
E.g., imagining that the "c" action in:
vCont;s:1;c
overflows the packet buffer, we split the actions like:
vCont;s:1
vCont;c
Tested on x86_64 Fedora 20, with and without "maint set
target-non-stop on".
Also tested with a hack that makes remote_commit_resume flush the vCont
packet after every action appended (which caught a few bugs).

gdbserver: Leave already-vCont-resumed threads as they were
Currently GDB never sends more than one action per vCont packet, when
connected in non-stop mode. A follow up patch will change that, and
it exposed a gdbserver problem with the vCont handling.
For example, this in non-stop mode:
=> vCont;s:p1.1;c
<= OK
Should be equivalent to:
=> vCont;s:p1.1
<= OK
=> vCont;c
<= OK
But gdbserver currently doesn't handle this. In the latter case,
"vCont;c" makes gdbserver clobber the previous step request. This
patch fixes that.
Note the server side must ignore resume actions for the thread that
has a pending %Stopped notification (and any other threads with events
pending), until GDB acks the notification with vStopped. Otherwise,
e.g., the following case is mishandled:
#1 => g (or any other packet)
#2 <= [registers]
#3 <= %Stopped T05 thread:p1.2
#4 => vCont s:p1.1;c
#5 <= OK
Above, the server must not resume thread p1.2 when it processes the
vCont. GDB can't know that p1.2 stopped until it acks the %Stopped
notification. (Otherwise it wouldn't send a default "c" action.)
(The vCont documentation already specifies this.)
Finally, special care must also be given to handling fork/vfork
events. A (v)fork event actually tells us that two processes stopped
-- the parent and the child. Until we follow the fork, we must not
resume the child. Therefore, if we have a pending fork follow, we
must not send a global wildcard resume action (vCont;c). We can still
send process-wide wildcards though.
(The comments above will be added as code comments to gdb in a follow
up patch.)

This apparently is due to - man gcc - -fsplit-stack:
When code compiled with -fsplit-stack calls code compiled without
-fsplit-stack, there may not be much stack space available for the
latter code to run. If compiling all code, including library code,
with -fsplit-stack is not an option, then the linker can fix up these
calls so that the code compiled without -fsplit-stack always has
a large stack. Support for this is implemented in the gold linker in
GNU binutils release 2.21 and later.

Convert dwarf_expr_context_funcs to methods
This patch converts the function pointers in dwarf_expr_context_funcs
into methods on dwarf_expr_context, and then updates the various
implementations and callers to follow.
NB this patch uses "override" (which caught a couple of renaming bugs
during development) -- but this is C++11, so this patch at least has
to wait for Pedro's patch that adds the OVERRIDE macro.
After this patch it would be possible to do one more, that makes
various members of dwarf_expr_context "protected"; but I haven't done
this.

This removes make_command_stats_cleanup in favor of an RAII class.
The patch is reasonably straightforward, but keeping the same
semantics without excessive reindentation required splitting
captured_main in two.

Remove make_cleanup_restore_current_ui
This removes make_cleanup_restore_current_ui by converting the last
use. The last use was in a few functions used to iterate over all
UIs. This patch replaces these functions with a class, and arranges
for the class destructor to do the needed cleanup.

Change minimal_symbol_reader to store objfile
This changes minimal_symbol_reader to require the objfile to be
passed to the constructor. The class now records the objfile and
automatically uses it later in "install".
This is a minor cleanup that will come in useful in the next patch.
It is separate from the first patch to keep that one a bit simpler to
understand.

Use RAII to save and restore scalars
This patch replaces many (but not all) uses of
make_cleanup_restore_integer with a simple RAII-based template class.
It also removes the similar restore_execution_direction cleanup in
favor of this new class. Subsequent patches will replace other
similar cleanups with this class.
The class is typically instantiated using make_scoped_restore. This
allows for template argument deduction.

Fix symbol table file name on AIX
When xlc -qfuncsect or gcc -ffunction-sections options is used in AIX,
each function csect is associated with each psymtab, so each psymtab
will have it's corresponding filename entries set.
If the pst filename isn't set then we will be seeing the below output
when we set a breakpoint.
(gdb) br main
Breakpoint 1 at 0x10000374: file _start_ , line 18.

gdb: no longer define __STDC_CONSTANT_MACROS/__STDC_LIMIT_MACROS
My gnulib fix at:
https://lists.gnu.org/archive/html/bug-gnulib/2015-11/msg00010.html
was merged upstream meanwhile and our gnulib copy now includes it.
As a concidence, Kevin was telling me today that these macros are
causing a build problem on FreeBSD:
common/common-defs.h:47:0: error: "__STDC_CONSTANT_MACROS" redefined [-Werror]
#define __STDC_CONSTANT_MACROS 1
/usr/include/sys/cdefs.h:408:0: note: this is the location of the previous definition
#define __STDC_CONSTANT_MACROS
(and a similar error for __STDC_LIMIT_MACROS)
The problem seems to be that we should be defining these input macros
before including any system header, but, we're not.
So let's just revert e063da67902e ([C++] Define __STDC_CONSTANT_MACROS
/ __STDC_LIMIT_MACROS for stdint.h). If this causes a problem
somewhere, we can re-define the macros higher up in the file, before
system headers are included.

Update gnulib to current upstream master
I tried building gdb with G++ 4.7 and CXX="g++ -std=gnu+11", and that
tripped on a build error:

Updating gnulib to current master fixes it, since it brings in this
fix:
http://lists.gnu.org/archive/html/bug-gnulib/2016-04/msg00000.html
Our last update was in August 2015. This doesn't bring in much added
baggage, it's mostly bug fixes. It pulled in the "limits-h" module as
automatic dependency, and given that looks potentially useful I added
it to the set of modules we require.
Tested on x86_64 Fedora 23, with g++ 4.7 and g++ 5.3, native and gdbserver.

Introduce gdb::unique_ptr
Many make_cleanup uses in the code base are best eliminated by using a
"owning" smart pointer to manage ownership of the resource
automatically.
The question is _which_ smart pointer.
GDB currently supports building with a C++03 compiler. We have
std::auto_ptr in C++03, but, as is collective wisdom by now, that's
too easy to misuse, and has therefore been deprecated in C++11 and
finally removed in C++17.
It'd be nice to be able to use std::unique_ptr instead, which is the
modern, safe std::auto_ptr replacement in C++11.
In addition to extra safety -- moving (i.e., transfer of ownership of
the managed pointer between smart pointers) must be explicit --
std::unique_ptr has (among others) one nice feature that std::auto_ptr
doesn't --- ability to specify a custom deleter as template parameter.
In gdb's context, that allows easily creating a smart pointer for
memory allocated with xmalloc -- the smart pointer then knows to
release with xfree instead of delete. This is particularly
interesting when managing objects allocated in C libraries, and also,
for C++-fying parts of GDB that interact with other parts that still
return objects allocated with xmalloc.
Since std::unique_ptr's API is quite nice, and eventually we'd like to
move to C++11, this patch adds a C++03-compatible smart pointer that
exposes the subset of the std::unique_ptr API that we're interested
in. An advantage is that whenever we start requiring C++11, we won't
have to learn a new API. Meanwhile, this allows continuing to support
building with a C++03 compiler.
Since C++03 doesn't support rvalue references (boost gets close to
emulating them, but it's not fully transparent to user code), the
C++03 std::unique_ptr emulation here doesn't try hard to prevent
accidentally moving, which is where most of complication of a more
thorough emulation would be. Instead, we rely on the fact that GDB
will be usually compiled with a C++11 compiler, and use the real
std::unique_ptr in that case to catch such accidental moves. IOW, the
goal here is to allow code that would be correct using std::unique_ptr
to be equally correct in C++03 mode, and, just as efficient.
The C++03 version was originally based on GCC 7.0's std::auto_ptr and
then heavily customized to behave more like C++11's std::unique_ptr:
- Support for custom (stateless) deleters. (Support for stateful
deleters could be added, if necessary.)
- unique_ptr<T[]> partial specialization (auto_ptr<T> does not know
to use delete[]).
- Support for all of 'ptr != NULL', 'ptr == NULL' and 'if (ptr)'
using the safe bool idiom to emulate C++11's explicit bool
operator.
- There's no nullptr in C++03, so this allows initialization and
assignment from NULL instead (std::auto_ptr allows neither).
- Variable names un-uglified (ie., no leading __ prefix everywhere).
- Formatting made to follow GDB's coding conventions, including
comment style.
- Converting "move" constructors done differently in order to truly
support:
unique_ptr<Derived> func_returning_unique_ptr (.....);
...
unique_ptr<Base> ptr = func_returning_unique_ptr (.....);
At this point, it no longer shares much at all with the original file,
but, that's the history.
See comments in the code to find out more.
I thought of putting the "emulation" / shim in the "std" namespace, so
that when we start requiring C++11 at some point, no actual changes to
users of the smart pointer throughout would be necessary. Putting
things in the std namespace is technically undefined, however in
practice it doesn't cause any issue with any compiler. However,
thinking that people might be confused with seeing std::unique_ptr and
thinking that we're actually requiring C++11 already, I put the new
types in the "gdb" namespace instead.
For managing xmalloc pointers, this adds a gdb::unique_xmalloc_ptr<T>
"specialization" with a custom xfree deleter.
No actual use of any smart pointer is introduced in this patch.
That'll be done in following patches.
Tested (along with the rest of the series) on:
- NetBSD 5.1 (gcc70 on the compile farm), w/ gcc 4.1.3
- x86-64 Fedora 23, gcc 5.3.1 (gnu++03)

gdb: Fix phony iconv build
Cross building gdb for mingw32 on Fedora 23 fails with:
x86_64-w64-mingw32-g++ -g -O2 [...] ../../src/gdb/charset.c
In file included from ../../src/gdb/charset.c:21:0:
../../src/gdb/charset.h:134:3: error: 'iconv_t' does not name a type

size_t r = iconv (m_desc, &inptr, &m_bytes, &outptr, &out_avail);
^
This is a regression caused by commit cda6c55bd399 (Turn wchar
iterator into a class). The problem is that iconv_t is now exposed in
gdb/charset.h, while before it was only used in gdb/charset.c.
gdb/charset.c, under #ifdef PHONY_ICONV, does:
#undef iconv_t
#define iconv_t int
So it seems the simplest is to use 'int' in the header file too.

[ARC] Disassembler: fix LIMM detection for short instructions.
The ARC (short) instructions are using a special register number to
indicate is the instruction uses a long immediate (LIMM). In the case
of short instruction, this LIMM indicator depends on the ISA version
used. Thus, for ARCv1 processors, the LIMM indicator is 0x3E, the same
value used in "long" instructions. However, for the ARCv2 processors,
this LIMM indicator is 0x1E.
This patch fixes the LIMM detection for ARCv1 ISA and adds two tests.

Convert tid_range_parser and get_number_or_range to classes
This converts tid_range_parser and get_number_or_range to be classes.
The various tid_range_parser_* and get_number_or_range_* functions
become methods on the respective classes. Then it updates the users
to follow.
The rationale for the change is that this provides better
encapsulation. For example, this forced me to think of a better
interface between tid_range_parser and get_number_or_range, since the
former peeked into the latter's internals a bit too much. That ended
up resulting mostly in these two not-just-straight-1-1 changes:
void
-tid_range_parser_skip (struct tid_range_parser *parser)
+tid_range_parser::skip_range ()
{
...
- tid_range_parser_init (parser, parser->range_parser.end_ptr,
- parser->default_inferior);
+ m_range_parser.skip_range ();
+ init (m_range_parser.string (), m_default_inferior);
}
and:
/* If we successfully parsed a thread number or finished parsing a
thread range, switch back to assuming the next TID is
inferior-qualified. */
- if (parser->range_parser.end_ptr == NULL
- || parser->range_parser.string == parser->range_parser.end_ptr)
+ if (!m_range_parser.in_range ())
{
For the same reason (encapsulation), this moves the enum
tid_range_state definition to within the tid_parser class's scope,
since that is private implementation detail.
While at it, switch to use "bool" for booleans.

Fixup gdb.python/py-value.exp for bare-metal aarch64-elf
I noticed that testing aarch64-elf gdb with a physical board
ran into issues with gdb.python/py-value.exp. Further investigation showed
that we were actually trying to dereference a NULL pointer (argv) when trying
to access argv[0].
Being bare-metal, argv is not guaranteed to be valid. So we need to make sure
argv is sane before accessing argv[0].
The following patch fixes up the test program to check for a NULL argv and also
improves the testcase a bit so it doesn't have to work with a hardcoded argc
value.
Regression-tested on x86-64 Ubuntu 16.04.
gdb/testsuite/ChangeLog:
2016-10-12 Luis Machado <lgustavo@codesourcery.com>
* gdb.python/py-value.c (main): Check if argv is NULL before using it.
* gdb.python/py-value.exp (test_value_in_inferior): Don't use hardcoded
argc values.
Add 1 to argc so we guarantee distinct initial/modified argc values.

Always descend into output section statements in lang_do_assignments
See https://sourceware.org/ml/binutils/2016-07/msg00091.html
This patch stop --gc-sections elf_gc_sweep_symbol localizing symbols
that ought to remain global.
The difficulty with always descending into output section statements
is that symbols defined by the script in such statements don't have
a bfd section when lang_do_assignments runs early in the link process.
There are two approaches to curing this problem. Either we can
create the bfd section early, or we can use a special section. This
patch takes the latter approach and uses bfd_und_section. (Creating
bfd sections early results in changed output section order, and thus
lots of testsuite failures. You can't create all output sections
early to ensure proper ordering as KEEP then stops empty sections
from being stripped.)
The wrinkle with this approach is that some code that runs at
gc-sections time needs to be made aware of the odd defined symbols
using bfd_und_section.

MIPS64: Adjust cfi* testcases.
The CFI* testcases fail on MIPS64 because the augmentation string does
not match the regexp. This is because MIPS64 doesn't use the default of
4 for DWARF2_FDE_RELOC_SIZE which ends up as "b" in the augmentation
string. MIPS64 uses the address size which is 8 resulting in "c".
Adding c to the regexp fixes a couple of them. Others also need
adjustments in the FDE header lines due to different
sizes/offsets.

Consolidate API of target_supports_multi_process
This simple commit consolidates the API of
target_supports_multi_process. Since both GDB and gdbserver use the
same function prototype, all that was needed was to move create this
prototype on gdb/target/target.h and turn the macros declared on
gdb/{,gdbserver/}target.h into actual functions.
Regtested (clean pass) on the BuildBot.

Remove Java support
This patch removes the Java support from gdb. gcj has not seen much
development or use for years now, and was recently removed from GCC.
This patch changes gdb to follow; in the unlikely event that there are
still users using gcj, they can continue to use an older gdb to debug.
Or, they can debug in C++ mode.
Built and regtested on x86-64 Fedora 24.

mips-tdep: Make FCRs always 32-bit
Fix a regression from commit f8b73d13b7ca ("Target-described register
support for MIPS"),
<https://sourceware.org/ml/gdb-patches/2007-05/msg00340.html>,
<https://sourceware.org/ml/gdb-patches/2007-06/msg00256.html>, which
caused Floating Point Control Registers (FCRs) to be shown as 64-bit
with 64-bit targets.
This came from the legacy register format where all raw registers
matched the width of the architecture regardless of their actual size.
The correct size was then set in `mips_register_type' for cooked
registers presented to the user, which in the case of FCRs meant the
cooked size was always forced to 32 bits, reflecting their actual
hardware size, even though the raw format carried them in 64-bit
quantities on 64-bit targets. The upper 32 bits carried in the raw FCR
format have always been don't-cares, not actually retrieved from
hardware and never written back.
With the introduction of XML register descriptions the layout of
previously defined raw registers has been preserved, so as to keep
existing register handling code unchanged and make it easier for GDB and
`gdbserver' to interact with each other whether neither, either or both
parties talking over RSP support XML register descriptions. For the
XML-described case however `mips_register_type' is not used in raw to
cooked register conversion, so any special cases coded there are not
taken into account.
Instead a new function, `mips_pseudo_register_type', has been introduced
to handle size conversion, however lacking the special case for FCRs for
the Linux and the now defunct IRIX target. The correct size has been
maintained for embedded targets however, due to the bundling of FCRs
with the embedded registers under the `rawnum >= MIPS_EMBED_FP0_REGNUM +
32' condition.
Add the missing case to `mips_pseudo_register_type' then, referring to
the FCR indices explicitly, and observing that between
`MIPS_EMBED_FP0_REGNUM + 32' and `MIPS_FIRST_EMBED_REGNUM' there is an
unused register slot whose contents are ignored so with the removal of
embedded FCRs from under that condition we don't have to care about it
and we can refer to the embedded registers starting from
MIPS_FIRST_EMBED_REGNUM instead.
Add a test case too so that we have means to check automatically that
the correct user-visible size of FCRs is maintained.

Fix PR11094: JIT breakpoint is not properly recreated on reruns

[...]
This is GDB trying to print the location spec of the JIT event
breakpoint, but that's an internal breakpoint without one.
If I add a NULL check, then we see that the JIT breakpoint is now
pending (because its location has shlib_disabled set):
(gdb) maint info breakpoints
Num Type Disp Enb Address What
[...]
-8 jit events keep y <PENDING> inf 1
[...]
But that's incorrect. GDB should have managed to recreate the JIT
breakpoint's location for the second run. So the problem is
elsewhere.
The problem is that if the JIT loads at the same address on the second
run, we never recreate the JIT breakpoint, because we hit this early
return:
static int
jit_breakpoint_re_set_internal (struct gdbarch *gdbarch,
struct jit_program_space_data *ps_data)
{
[...]
if (ps_data->cached_code_address == addr)
return 0;
[...]
delete_breakpoint (ps_data->jit_breakpoint);
[...]
ps_data->jit_breakpoint = create_jit_event_breakpoint (gdbarch, addr);
Fix this by deleting the breakpoint and discarding the cached code
address when the objfile where the previous JIT breakpoint was found
is deleted/unloaded in the first place.
The test that was originally added for PR11094 doesn't trip on this
because:
#1 - It doesn't test the case of the JIT descriptor's address _not_
changing between reruns.
#2 - And then it doesn't do "maint info breakpoints", or really
anything with the JIT at all.
#3 - and even then, to trigger the problem the JIT descriptor needs
to be in a separate library, while the current test puts it in
the main program.
The patch extends the test to cover all combinations of these
scenarios.

$1 = (struct jit_descriptor *) 0x601040 <__jit_debug_descriptor>
(gdb) PASS: gdb.base/jit-simple.exp: blah 1
[...]
(gdb) run
[...]
Starting program: build/gdb/testsuite/outputs/gdb.base/jit-simple/jit-simple
Unsupported JIT protocol version 4 in descriptor (expected 1)
Breakpoint 2, main () at src/gdb/testsuite/gdb.base/jit-simple.c:36
36 return 0;
(gdb) print &__jit_debug_descriptor
$2 = (struct jit_descriptor *) 0x601040 <__jit_debug_descriptor>
(gdb) PASS: gdb.base/jit-simple.exp: blah 1
All tests PASSed, but note the "Unsupported JIT protocol version 4"
message.
Also notice that "__jit_debug_descriptor" has the same address before
and after the rerun, while the test is built in a way that should make
that address change between runs.
The test doesn't catch any of this because it doesn't compare
before/after addresses.
And then notice the "blah 1" test messages. "blah" is clearly a WIP
message, but it should be at least "blah 2" the second time. :-)
The reason this sometimes happens is that the test recompiles the
program and expects gdb to reload it automaticallyt on "run". However,
if the original program and the new recompilation happen to be in the
same second, then gdb does not realize that the binary needs to be
reloaded. (This is an old problem out of scope of this series.) If
that happens, then GDB ends up using the wrong symbols for the program
that it spawns, reads the JIT descriptor out of the wrong address,
finds garbage, and prints that "unsupported version" notice.
Fix that in the same way gdb.base/reread.exp handles it -- by sleeping
one second before recompiling.

Refine .cfi_sections check to only consider compact eh_frame
The .cfi_sections directive can be safely used multiple times
with different sections named at any time unless the compact form
of exception handling is requested after CFI information has
been emitted. Only the compact form of CFI information changes
the way in which CFI is generated and therefore cannot be
retrospectively requested after generating CFI information.

The .exp patch is an obvious typo fix I think. The regex was written to
accept "ADDR in main" and I find it OK as checking .debug_line validity is not
the purpose of this testfile.
gcc-4.8.5-11.el7.x86_64 did not put the 'mov $0x0,%eax' instruction there at
all so there was no problem with .debug_line.

Allow DW_OP_GNU_uninit in dwarf_expr_require_composition
In DWARF expression handling, some operators are required to be either
at the end of an expression or followed by a composition operator. So
far only the operators DW_OP_reg0-31 were allowed to be followed by
DW_OP_GNU_uninit instead, and particularly DW_OP_regx was not, which is
obviously inconsistent.
This patch allows DW_OP_GNU_uninit after all operators requiring a
composition, to simplify the code and make it more consistent. This
policy may be more permissive than necessary, but in the worst case just
leads to a DWARF location description resulting in an uninitialized
value instead of an error message.
gdb/ChangeLog:
* dwarf2expr.c (dwarf_expr_require_composition): Allow
DW_OP_GNU_uninit.
(execute_stack_op): Use dwarf_expr_require_composition instead of

arc: Remove annoying debug message
The logging message is called too often - once for each register when it's
value has to be evaluated. This floods the screen for commands like "info
register all", but doesn't give really any help at debugging GDB issues.
Between increasing the debug level of this message and removing it altogether I
think that removing it is preferable.

bar/foo-baz-expedite or foo-expedite. In x86 expedite registers, we
use the former now, but it will be much simpler if we use the latter.
This is what this patch does. This patch removes them, and defines
three generic expedite. Re-run 'make GDB=/path/build/gdb all' to
regenerate regformats/*.dat files, and they are not changed.

Fold arithmetic integer expressions
Commit b751e639 regressed arm linux kernel builds, that have an
ASSERT (((__hyp_idmap_text_end - (__hyp_idmap_text_start
& ~ (((0x1 << 0xc) - 0x1))))
<= (0x1 << 0xc)), HYP init code too big or misaligned)
Due to some insanity in ld expression evaluation, the integer values
0x1 and 0xc above are treated as absolute addresses (ie. they have an
associated section, *ABS*, see exp_fold_tree_1 case etree_value) while
the expression (0x1 << 0xc) has a plain number result. The left hand
side of the inequality happens to evaluate to a "negative" .text
section relative value. Comparing a section relative value against an
absolute value works since the section relative value is first
converted to absolute. Comparing a section relative value against a
number just compares the offsets, which fails since the "negative"
offset is really a very large positive number.
This patch works around the problem by folding integer expressions, so
the assert again becomes
ASSERT (((__hyp_idmap_text_end - (__hyp_idmap_text_start
& 0xfffffffffffff000))
<= 0x1000), HYP init code too big or misaligned)
* ldexp.c (exp_value_fold): New function.
(exp_unop, exp_binop, exp_trinop): Use it.

Add test for user context selection sync
This patch adds a test to verify that events are sent properly to all
UIs when the user selection context (inferior, thread, frame) changes.
The goal of the C test file is to provide two threads that are stopped with the
same predictable backtrace (so that we can test frame switching). The barrier
helps us know when the child threads are started. Then, scheduler-locking is
used to bring each thread one by one to the position we expect them to be
during the test.

Emit inferior, thread and frame selection events to all UIs
With this patch, when an inferior, thread or frame is explicitly
selected by the user, notifications will appear on all CLI and MI UIs.
When a GDB console is integrated in a front-end, this allows the
front-end to follow a selection made by the user ont he CLI, and it
informs the user about selection changes made behind the scenes by the
front-end.
This patch addresses PR gdb/20487.
In order to communicate frame changes to the front-end, this patch adds
a new field to the =thread-selected event for the selected frame. The
idea is that since inferior/thread/frame can be seen as a composition,
it makes sense to send them together in the same event. The vision
would be to eventually send the inferior information as well, if we find
that it's needed, although the "=thread-selected" event would be
ill-named for that job.
Front-ends need to handle this new field if they want to follow the
frame selection changes that originate from the console. The format of
the frame attribute is the same as what is found in the *stopped events.
Here's a detailed example for each command and the events they generate:
thread
------
1. CLI command:
thread 1.3
MI event:
=thread-selected,id="3",frame={...}
2. MI command:
-thread-select 3
CLI event:
[Switching to thread 1.3 ...]
3. MI command (CLI-in-MI):
thread 1.3
MI event/reply:
&"thread 1.3\n"
~"#0 child_sub_function () ...
=thread-selected,id="3",frame={level="0",...}
^done
frame
-----
1. CLI command:
frame 1
MI event:
=thread-selected,id="3",frame={level="1",...}
2. MI command:
-stack-select-frame 1
CLI event:
#1 0x00000000004007f0 in child_function...
3. MI command (CLI-in-MI):
frame 1
MI event/reply:
&"frame 1\n"
~"#1 0x00000000004007f9 in ..."
=thread-selected,id="3",frame={level="1"...}
^done
inferior
--------
Inferior selection events only go from the console to MI, since there's
no way to select the inferior in pure MI.
1. CLI command:
inferior 2
MI event:
=thread-selected,id="3"
Note that if the user selects an inferior that is not started or exited,
the MI doesn't receive a notification. Since there is no threads to
select, the =thread-selected event does not apply...
2. MI command (CLI-in-MI):
inferior 2
MI event/reply:
&"inferior 2\n"
~"[Switching to inferior 2 ...]"
=thread-selected,id="4",frame={level="0"...}
^done
Internal implementation detail: this patch makes it possible to suppress
notifications caused by a CLI command, like what is done in mi-interp.c.
This means that it's now possible to use the
add_com_suppress_notification function to register a command with some
event suppressed. It is used to implement the select-frame command in
this patch.
The function command_notifies_uscc_observer was added to extract
the rather complicated logical expression from the if statement. It is
also now clearer what that logic does: if the command used by the user
already notifies the user_selected_context_changed observer, there is
not need to notify it again. It therefore protects again emitting the
event twice.
No regressions, tested on ubuntu 14.04 x86 with target boards unix and
native-extended-gdbserver.

PR gdb/20609 - attach of JIT-debug-enabled inf 7.11.1 regression
Regression: gdb --pid $(pidof qemu-system-x86_64) stopped working with gdb 7.11.1

Message-ID: <cbdf2e04-4fa8-872a-2a23-08c9c1b26e00@redhat.com>
https://sourceware.org/ml/gdb-patches/2016-05/msg00450.html
jit_breakpoint_re_set() is specific by trying to insert a breakpoint into the
main executable, not into a shared library. During attachment GDB thinks it
needs to use 'breakpoint always-inserted' from
breakpoints_should_be_inserted_now() as a newly attached thread is
'thread_info->executing' due to 'lwp_info->must_set_ptrace_flags' enabled and
the task not yet stopped. This did not happen before the 'bad commit' above
which adds tracking of such thread.
GDB then fails to insert the breakpoints to invalid address as PIE executable
gets properly relocated during later phase of attachment. One can see in the
backtraces below:
-> jit_breakpoint_re_set_internal()
later:
-> svr4_exec_displacement()
One can suppress the initial breakpoint_re_set() call as there will be another
breakpoint_re_set() done from the final post_create_inferior() call in
setup_inferior().
BTW additionally 'threads_executing' cache bool is somehow stale (somewhere is
missing update_threads_executing()). I was trying to deal with that in my
first/second attempt below but in my final third attempt (attached) I have
left it as it is.
First attempt trying not to falsely require 'breakpoint always-inserted':
https://people.redhat.com/jkratoch/rhbz1375553-fix1.patch
Reduced first attempt:
https://people.redhat.com/jkratoch/rhbz1375553-fix2.patch
The third attempt suppresses breakpoint insertion until PIE executable gets
relocated by svr4_exec_displacement(). Applied.

This is triggered by this check in display_debug_frames (dwarf.c):
case DW_CFA_restore:
if (opa >= (unsigned int) cie->ncols
|| opa >= (unsigned int) fc->ncols)
reg_prefix = bad_reg;
cie->ncols is number of registers referenced in the CIE which is 15 due
to r14 being given as return address column. So for the CFA_restore of
r15 a "bad register" is being printed while the same rule on r14 is ok.
The reason for this check is to prevent wild memory accesses when
reading input with corrupted register values while accessing the
col_type/col_offset arrays. However in that case r15 is a perfectly
valid register. It just happens not to be mentioned in the CIE. Hence
restoring the CIE rule for r15 should end up with the default rule which
is DW_CFA_undefined.
This probably wasn't observed on other platforms because they either do
not use CFA_restore (x86-64) or do not issue CFA_restore on registers
with a higher number than the return address column.

If you run an infcall from the command line, and immediately after run
some other command, GDB incorrectly processes the other command before

The problem is that the fix for PR gdb/20418 (Problems with

Small improvements to the remote protocol manual
I was reading the gdb RSP manual recently and I found a number of
small problems in the documentation. This patch attempts to improve
these areas. Specfically:
* The term "memory breakpoint" is used only in this section of the
manual, and there inconsistently. I found this term confusing --
initially I thought it might be a watchpoint. This patch changes it
to use the term "software breakpoint", which is used in the rest of
the manual.
* The z0 packet didn't document how "kind" was written. And, it had a
stray link to the architecture-specific protocol details node. This
patch moves this link to a better spot.
* The z1 patch didn't document that it accepts cmd_list.
* I couldn't find any text saying what response is given to a command
like vCont in non-stop mode. The answer is that OK is sent, and
then a stop reply is sent as a notification. This patch adds a note
about this.
* The "create" stop reply did not document that the "R" argument is
ignored.
* The "W", "X", and "w" packets did not document how the "AA" part is
formatted.
* The %Stop notification example said "%%Stop", but I think this is
incorrect.
2016-09-28 Tom Tromey <tom@tromey.com>
* gdb.texinfo (Packets) <z0>: Use "software breakpoint" rather
than "memory breakpoint". Further document "kind". Move
protocol-details link earlier.
<z1>: Document the cmd_list argument. Fix typo.
<g>: Remove incorrect sentence.
(Stop Reply Packets): Document "OK" response to requests when in

<swbreak>: Use "software breakpoint" rather than "memory

PowerPC .gnu.attributes
This patch extends Tag_GNU_Power_ABI_FP to cover long double ABIs,
makes the assembler warn about undefined tag values, and removes
similar warnings from the linker. I think it is better to not
warn in the linker about undefined tag values as future extensions to
the tags then won't result in likely bogus warnings. This is
consistent with the fact that an older linker won't warn on an
entirely new tag.

gdb: Replace operator new / operator new[]
If xmalloc fails allocating memory, usually because something tried a
huge allocation, like xmalloc(-1) or some such, GDB asks the user what
to do:
.../src/gdb/utils.c:1079: internal-error: virtual memory exhausted.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
If the user says "n", that throws a QUIT exception, which is caught by
one of the multiple CATCH(RETURN_MASK_ALL) blocks somewhere up the
stack.
The default implementations of operator new / operator new[] call
malloc directly, and on memory allocation failure throw
std::bad_alloc. Currently, if that happens, since nothing catches it,
the exception escapes out of main, and GDB aborts from unhandled
exception.
This patch replaces the default operator new variants with versions
that, just like xmalloc:
#1 - Raise an internal-error on memory allocation failure.
#2 - Throw a QUIT gdb_exception, so that the exact same CATCH blocks
continue handling memory allocation problems.
A minor complication of #2 is that operator new can _only_ throw
std::bad_alloc, or something that extends it:
void* operator new (std::size_t size) throw (std::bad_alloc);
That means that if we let a gdb QUIT exception escape from within
operator new, the C++ runtime aborts due to unexpected exception
thrown.
So to bridge the gap, this patch adds a new gdb_quit_bad_alloc
exception type that inherits both std::bad_alloc and gdb_exception,
and throws _that_.
If we decide that we should be catching memory allocation errors in
fewer places than all the places we currently catch them (everywhere
we use RETURN_MASK_ALL currently), then we could change operator new
to throw plain std::bad_alloc then. But I'm considering such a change
as separate matter from this one -- it'd make sense to do the same to
xmalloc at the same time, for instance.
Meanwhile, this allows using new/new[] instead of xmalloc/XNEW/etc.
without losing the "virtual memory exhausted" internal-error
safeguard.
Tested on x86_64 Fedora 23.

Close gdbserver in mi_gdb_exit
In commit 6423214f (testsuite: Don't use expect_background to reap
gdbserver), we override gdb_exit in lib/gdbserver-support.exp, so
that we can close gdbserver first. However, we don't close gdbserver
in mi_gdb_exit. This makes a problem in my aarch64 mulit-arch testing,
in which I run some mi tests, mi-watch.exp for example, in different
variations (aarch64 and arm),
Schedule of variations:
junor0-2
junor0-2-arm/-marm
junor0-2-arm/-mthumb
When the test is done in the first variation (aarch64), test case is
recompiled for arm, but GDBserver with aarch64 program is still
running. When the second variation is started, GDB loads arm program,
but GDBserver still loads aarch64 program because the old GDBserver
process is using it. We'll get,
47-target-select remote junor0-2:2350^M
&"warning: Selected architecture arm is not compatible with reported target architecture aarch64\n"^M
&"warning: Architecture rejected target-supplied description\n"
This patch fixes this problem by closing GDBserver in mi_gdb_exit.

arc: New Synopsys ARC port
ARC is a family of licensable processors developed by Synopsys.
This is an initial patch that doesn't yet support some of the features, that
are already available in Synopsys' fork of GDB, namely:
* longjmp support
* signal frame handling
* prologue analysis
* Linux targets support
* native Linux support
ARC cores are configurable and extensible, which means from debugger
perspective that some registers and debug capabilities are optional, therefore
it is up to the GDB stub to determine exact list of register available on
target and supply it to GDB via XML target descriptions. List of registers
that is known to GDB and is required is intentionally kept small to simplify
requirements to GDB stub and implementation of a GDB client.

PR gdb/20604 - fix "quit" when an invalid expression is used
This fixes PR gdb/20604. The bug here is that passing an invalid
expression to "quit" -- e.g., "quit()" -- causes gdb to enter a
non-functioning state.
The immediate problem is that quit_force resets the terminal before
evaluating the expression. However, it seemed to me that it doesn't
really make sense to pass the quit_force argument to kill_or_detach
(which passes it to to_detach), first because conflating the exit
status for "quit" and the signal to pass when detaching doesn't make
sense, and second because to_detach implementations generally only
accept a constant here, while "quit" accepts an expression. So, I
removed that.
As an aside, I think the "detach SIGNO" functionality is not
documented.
Built and regtested on x86-64 Fedora 24.

[AArch64] Print spaces after commas in addresses
I got an off-list request to make the AArch64 disassembler print
spaces after commas in addresses. This patch does that.
The same code is used to print operands in "did you mean" errors,
so to keep things consistent, the patch also prints spaces between
operands in those messages.

[AArch64] Use "must" rather than "should" in error messages
One of the review comments from the SVE series was that it would
be better to use "must" rather than "should" in error messages.
I think this patch fixes all cases in the AArch64 code.
It also uses "must be" instead of "expected to be".

rather than "should be" or "expected to be" in error messages.

[AArch64] Add SVE condition codes
SVE defines new names for existing NZCV conditions, to reflect the
result of instructions like PTEST. This patch adds support for these
names.
The patch also adds comments to the disassembly output to show the
alternative names of a condition code. For example:
cinv x0, x1, cc
becomes:
cinv x0, x1, cc // cc = lo, ul, last
and:
b.cc f0 <...>
becomes:
b.cc f0 <...> // b.lo, b.ul, b.last
Doing this for the SVE names follows the practice recommended by the
SVE specification and is definitely useful when reading SVE code.
If the feeling is that it's too distracting elsewhere, we could add
an option to turn it off.

[AArch64][SVE 28/32] Add SVE FP immediate operands
This patch adds support for the new SVE floating-point immediate
operands. One operand uses the same 8-bit encoding as base AArch64,
but in a different position. The others use a single bit to select
between two values.
One of the single-bit operands is a choice between 0 and 1, where 0
is not a valid 8-bit encoding. I think the cleanest way of handling
these single-bit immediates is therefore to use the IEEE float encoding
itself as the immediate value and select between the two possible values
when encoding and decoding.
As described in the covering note for the patch that added F_STRICT,
we get better error messages by accepting unsuffixed vector registers
and leaving the qualifier matching code to report an error. This means
that we carry on parsing the other operands, and so can try to parse FP
immediates for invalid instructions like:
fcpy z0, #2.5
In this case there is no suffix to tell us whether the immediate should
be treated as single or double precision. Again, we get better error
messages by picking one (arbitrary) immediate size and reporting an error
for the missing suffix later.

[AArch64][SVE 27/32] Add SVE integer immediate operands
This patch adds the new SVE integer immediate operands. There are
three kinds:
- simple signed and unsigned ranges, but with new widths and positions.
- 13-bit logical immediates. These have the same form as in base AArch64,
but at a different bit position.
In the case of the "MOV Zn.<T>, #<limm>" alias of DUPM, the logical
immediate <limm> is not allowed to be a valid DUP immediate, since DUP
is preferred over DUPM for constants that both instructions can handle.
- a new 9-bit arithmetic immediate, of the form "<imm8>{, LSL #8}".
In some contexts the operand is signed and in others it's unsigned.
As an extension, we allow shifted immediates to be written as a single
integer, e.g. "#256" is equivalent to "#1, LSL #8". We also use the
shiftless form as the preferred disassembly, except for the special
case of "#0, LSL #8" (a redundant encoding of 0).

[AArch64][SVE 26/32] Add SVE MUL VL addressing modes
This patch adds support for addresses of the form:
[<base>, #<offset>, MUL VL]
This involves adding a new AARCH64_MOD_MUL_VL modifier, which is
why I split it out from the other addressing modes.
For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, .... The patch
therefore extends value_aligned_p to handle non-power-of-2 alignments.

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

[AArch64][SVE 24/32] Add AARCH64_OPND_SVE_PATTERN_SCALED
Some SVE instructions count the number of elements in a given vector
pattern and allow a scale factor of [1, 16] to be applied to the result.
This scale factor is written ", MUL #n", where "MUL" is a new operator.
E.g.:
UQINCD X0, POW2, MUL #2
This patch adds support for this kind of operand.
All existing operators were shifts of some kind, so there was a natural
range of [0, 63] regardless of context. This was then narrowered further
by later checks (e.g. to [0, 31] when used for 32-bit values).
In contrast, MUL doesn't really have a natural context-independent range.
Rather than pick one arbitrarily, it seemed better to make the "shift"
amount a full 64-bit value and leave the range test to the usual
operand-checking code. I've rearranged the fields of aarch64_opnd_info
so that this doesn't increase the size of the structure (although I don't
think its size is critical anyway).

[AArch64][SVE 23/32] Add SVE pattern and prfop operands
The SVE instructions have two enumerated operands: one to select a
vector pattern and another to select a prefetch operation. The latter
is a cut-down version of the base AArch64 prefetch operation.
Both types of operand can also be specified as raw enum values such as #31.
Reserved values can only be specified this way.
If it hadn't been for the pattern operand, I would have been tempted
to use the existing parsing for prefetch operations and add extra
checks for SVE. However, since the patterns needed new enum parsing
code anyway, it seeemed cleaner to reuse it for the prefetches too.
Because of the small number of enum values, I don't think we'd gain
anything by using hash tables.

[AArch64][SVE 20/32] Add support for tied operands
SVE has some instructions in which the same register appears twice
in the assembly string, once as an input and once as an output.
This patch adds a general mechanism for that.
The patch needs to add new information to the instruction entries.
One option would have been to extend the flags field of the opcode
to 64 bits (since we already rely on 64-bit integers being available
on the host). However, the *_INSN macros mean that it's easy to add
new information as top-level fields without affecting the existing
table entries too much. Going for that option seemed to give slightly
neater code.

[AArch64][SVE 14/32] Make aarch64_logical_immediate_p take an element size
SVE supports logical immediate operations on 8-bit, 16-bit and 32-bit
elements, treating them as aliases of operations on 64-bit elements in
which the immediate is replicated. This patch therefore replaces the
"32-bit/64-bit" input to aarch64_logical_immediate_p with a more
general "number of bytes" input.

[AArch64][SVE 13/32] Add an F_STRICT flag
SVE predicate operands can appear in three forms:
1. unsuffixed: "Pn"
2. with a predication type: "Pn/[ZM]"
3. with a size suffix: "Pn.[BHSD]"
No variation is allowed: unsuffixed operands cannot have a (redundant)
suffix, and the suffixes can never be dropped. Unsuffixed Pn are used
in LDR and STR, but they are also used for Pg operands in cases where
the result is scalar and where there is therefore no choice to be made
between "merging" and "zeroing". This means that some Pg operands have
suffixes and others don't.
It would be possible to use context-sensitive parsing to handle
this difference. The tc-aarch64.c code would then raise an error
if the wrong kind of suffix is used for a particular instruction.
However, we get much more user-friendly error messages if we parse
all three forms for all SVE instructions and record the suffix as a
qualifier. The normal qualifier matching code can then report cases
where the wrong kind of suffix is used. This is a slight extension
of existing usage, which really only checks for the wrong choice of
suffix within a particular kind of suffix.
The only catch is a that a "NIL" entry in the qualifier list
specifically means "no suffix should be present" (case 1 above).
NIL isn't a wildcard here. It also means that an instruction that
requires all-NIL qualifiers can fail to match (because a suffix was
supplied when it shouldn't have been); this requires a slight change
to find_best_match.
This patch adds an F_STRICT flag to select this behaviour.
The flag will be set for all SVE instructions. The behaviour
for other instructions doesn't change.

[AArch64][SVE 12/32] Remove boolean parameters from parse_address_main
In the review of the original version of this series, Richard didn't
like the use of boolean parameters to parse_address_main. I think we
can just get rid of them and leave the callers to check the addressing
modes. As it happens, the handling of ADDR_SIMM9{,_2} already did this
for relocation operators (i.e. it used parse_address_reloc and then
rejected relocations).
The callers are already set up to reject invalid register post-indexed
addressing, so we can simply remove the accept_reg_post_index parameter
without adding any more checks. This again creates a corner case where:
.equ x2, 1
ldr w0, [x1], x2
was previously an acceptable way of writing "ldr w0, [x1], #1" but
is now rejected.
Removing the "reloc" parameter means that two cases need to check
explicitly for relocation operators.
ADDR_SIMM9_2 appers to be unused. I'll send a separate patch
to remove it.
This patch makes parse_address temporarily equivalent to
parse_address_main, but later patches in the series will need
to keep the distinction.
gas/

accept_reg_post_index parameters. Parse relocations and register

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

parameters.

[AArch64][SVE 09/32] Improve error messages for invalid floats
Previously:
fmov d0, #2
would give an error:
Operand 2 should be an integer register
whereas the user probably just forgot to add the ".0" to make:
fmov d0, #2.0
This patch reports an invalid floating point constant unless the
operand is obviously a register.
The FPIMM8 handling is only relevant for SVE. Without it:
fmov z0, z1
would try to parse z1 as an integer immediate zero (the res2 path),
whereas it's more likely that the user forgot the predicate. This is
tested by the final patch.

[AArch64][SVE 08/32] Generalise aarch64_double_precision_fmovable
SVE has single-bit floating-point constants that don't really
have any relation to the AArch64 8-bit floating-point encoding.
(E.g. one of the constants selects between 0 and 1.) The easiest
way of representing them in the aarch64_opnd_info seemed to be
to use the IEEE float representation directly, rather than invent
some new scheme.
This patch paves the way for that by making the code that converts IEEE
doubles to IEEE floats accept any value in the range of an IEEE float,
not just zero and 8-bit floats. It leaves the range checking to the
caller (which already handles it).
gas/

value that converts to single precision without loss of precision.

[AArch64][SVE 07/32] Replace hard-coded uses of REG_TYPE_R_Z_BHSDQ_V
To remove parsing ambiguities and to avoid register names being
accidentally added to the symbol table, the immediate parsing
routines reject things like:
.equ x0, 0
add v0.4s, v0.4s, x0
An explicit '#' must be used instead:
.equ x0, 0
add v0.4s, v0.4s, #x0
Of course, it wasn't possible to predict what other register
names might be added in future, so this behaviour was restricted
to the register names that were defined at the time. For backwards
compatibility, we should continue to allow things like:
.equ p0, 0
add v0.4s, v0.4s, p0
even though p0 is now an SVE register.
However, it seems reasonable to extend the x0 behaviour above to
SVE registers when parsing SVE instructions, especially since none
of the SVE immediate formats are relocatable. Doing so removes the
same parsing ambiguity for SVE instructions as the x0 behaviour removes
for base AArch64 instructions.
As a prerequisite, we then need to be able to tell the parsing routines
which registers to reject. This patch changes the interface to make
that possible, although the set of rejected registers doesn't change
at this stage.

[AArch64][SVE 01/32] Remove parse_neon_operand_type
A false return from parse_neon_operand_type had an overloaded
meaning: either the parsing failed, or there was nothing to parse
(which isn't necessarily an error). The only caller, parse_typed_reg,
would therefore not consume the suffix if it was invalid but instead
(successfully) parse the register without a suffix. It would still
leave inst.parsing_error with an error about the invalid suffix.
It seems wrong for a successful parse to leave an error message,
so this patch makes parse_typed_reg return PARSE_FAIL instead.
The patch doesn't seem to make much difference in practice.
Most possible follow-on errors use set_first_error and so the
error about the suffix tended to win despite the successful parse.
