gas: xtensa: make trampolines relaxation work with jumps in slots other than 0
add_jump_to_trampoline assumes that jump instruction is in slot 0,
when it's in other slot that results in fixup that references NULL symbol,
which results in segfault later in xtensa_make_cached_fixup.
Search for the non-NULL symbol in the tc_frag_data.slot_symbols and check
that there's exactly one such slot.
xtensa_relax_frag for RELAX_TRAMPOLINE reassigns fixup from the original
instruction with jump to generated jump in the trampoline frag, but does not
fix its fx_r_type or fx_size. That results in "undecodable fix" or
"fixup not contained within frag" error messages during relaxation.
Fix both these fields.

* config/tc-xtensa.c (xtensa_relax_frag): Change fx_size of the
reassigned fixup to size of jump instruction (3) and fx_r_type

(add_jump_to_trampoline): Search
origfrag->tc_frag_data.slot_symbols for the slot with non-NULL

Remove lwp -> pid conversion in linux_nat_xfer_partial
The linux_nat_xfer_partial does a conversion of inferior_ptid: if it's
an LWP (ptid::lwp != 0), it builds a new ptid with the lwp as
the pid and assigns that temporarily to inferior_ptid. For example, if
inferior_ptid is:
{ .pid = 1234, .lwp = 1235 }
it will assign this to inferior_ptid for the duration of the call:
{ .pid = 1235, .lwp = 0 }
Instead of doing this, this patch teaches the inf-ptrace implementation
of xfer_partial to deal with ptids representing lwps by using
get_ptrace_pid.
Also, in linux_proc_xfer_spu and linux_proc_xfer_partial, we use ptid_get_lwp
instead of ptid_get_pid. While not strictly necessary, since the content of
/proc/<pid> and /proc/<lwp> should be the same, it's a bit safer, because:
- some files under /proc/<pid>/ may not work if the <pid> thread is
running, just like ptrace requires a stopped thread. The current
thread's lwp id is more likely to be in the necessary state (stopped).
- if the leader (<pid>) had exited and is thus now zombie, then several
files under "/proc/<pid>" won't work, while they will if you use
"/proc/<lwp>".
The testsuite found no regression on native amd64 linux.
gdb/ChangeLog:
* inf-ptrace.c (inf_ptrace_xfer_partial): Get pid from ptid
using get_ptrace_pid.
* linux-nat.c (linux_nat_xfer_partial): Don't set/restore
inferior_ptid.
(linux_proc_xfer_partial, linux_proc_xfer_spu): Use lwp of
inferior_ptid instead of pid.

Wrap locally used classes in anonymous namespace
Both aarch64-tdep.c and arm-tdep.c defines a class instruction_reader, which
violates ODR, but linker doesn't an emit error. I fix this issue by wrapping
them by anonymous namespace, but I think it is better to apply this for all
locally used classes.
If it is a good idea to put locally used class into anonymous namespace, we
should document this rule into GDB coding convention, or even GCC coding
convention. Note that anonymous namespace has been used in GCC but GCC
coding convention doesn't mention the it.

windows: Use ptid from regcache in register fetch/store
Use the ptid from the regcache so we don't depend on the current value
of the inferior_ptid global.
Also, change how the current thread is passed to sub-functions. The
windows_fetch_inferior_registers function sets current_thread then calls
do_windows_fetch_inferior_registers, which reads current_thread. This
very much looks like passing a parameter through a global variable. I
think it would be more straightforward to pass the thread as a
parameter.
gdb/ChangeLog:
* windows-nat.c (do_windows_fetch_inferior_registers): Add
windows_thread_info parameter and use it instead of
current_thread.
(windows_fetch_inferior_registers): Don't set current_thread,
pass the thread to do_windows_fetch_inferior_registers. Use
ptid from regcache instead of inferior_ptid.
(do_windows_store_inferior_registers): Add windows_thread_info
parameter and use it instead of current_thread.
(windows_store_inferior_registers): Don't set current_thread,
pass the thread to do_windows_store_inferior_registers. Use
ptid from regcache instead of inferior_ptid.

Add rvalue reference tests and docs
This patch adds tests for the initial rvalue reference support patchset. All
of the new tests are practically mirrored regular references tests and, except
for the demangler ones, are introduced in new files, which are set to be
compiled with -std=gnu++11. Tested are printing of rvalue reference types and
values, rvalue reference parameters in function overloading, demangling of
function names containing rvalue reference parameters, casts to rvalue
reference types, application of the sizeof operator to rvalue reference types
and values, and support for rvalue references within the gdb python module.

Add rvalue references to overloading resolution
This patch introduces changes to rank_one_type() dealing with ranking an rvalue
reference type when selecting a best viable function from a set of candidate
functions. The 4 new added rules for rvalue references are:
1) An rvalue argument cannot be bound to a non-const lvalue reference parameter
and an lvalue argument cannot be bound to an rvalue reference parameter.
[C++11 13.3.3.1.4p3]
2) If a conversion to one type of reference is an identity conversion, and a
conversion to the second type of reference is a non-identity conversion, choose
the first type. [C++11 13.3.3.2p3]
3) An rvalue should be first tried to bind to an rvalue reference, and then to
an lvalue reference. [C++11 13.3.3.2p3]
4) An lvalue reference to a function gets higher priority than an rvalue
reference to a function. [C++11 13.3.3.2p3]
This patch is not exactly correct. See c++/15372 for tracking overload
resolution bugs.

Convert lvalue reference type check to general reference type check
In almost all contexts (except for overload resolution rules and expression
semantics), lvalue and rvalue references are equivalent. That means that in all
but these cases we can replace a TYPE_CODE_REF check to a TYPE_IS_REFERENCE
check and, for switch statements, add a case label for a rvalue reference type
next to a case label for an lvalue reference type. This patch does exactly
that.

readelf: Don't error on .debug files with NOBITS .dynamic section.
The fix for PR binutils/17512 added a check for the dynamic segment being
inside the actual ELF file. If not an error message would be produced:
readelf: Error: the dynamic segment offset + size exceeds the size of the file
Unfortunately for separate debuginfo files it is common for the dynamic
segment not being inside the file because the .dynamic section is NOBITS.
Since the check is done unconditionally in process_program_headers and
process_program_headers is always called (to setup dynamic_addr in case
it is needed). The error is produced on any operations done on any .debug
file (even if no program headers or the dynamic segment is used).
If there are section headers then a cross check is done to see if the
.dynamic section is NOBITS in which case dynamic_addr is set to zero
without a warning or error (which is then checked first before any
operation on the dynamic segement is done).
Move the check for the dynamic segment being inside the actual ELF file
after the cross check with the section headers to suppress the error for
.debug files.

* readelf.c (process_program_headers): Move dynamic_addr check

s390: Fix displaced-stepping certain relative branch insns
On s390x targets GDB can not handle displaced stepping correctly for some
relative branch instructions, such as cij (compare immediate and branch
relative). When setting a breakpoint on such an instruction and
single-stepping over it, the branch is never taken. This is because the
check in s390_displaced_step_fixup for relative branch instructions is
incomplete.
Instead of completing the list of relative branch instructions to check
against, this patch just treats relative branches and non-branching
instructions in the same way and adjusts the PC with the negated
displacement in both cases.

DT_TEXTREL vs IFUNC
If you should somehow link non-pic objects into a PIE or shared
library, resulting in an object with DT_TEXTREL (text relocations)
set, and your executable or shared library also contains GNU indirect
functions, then you're in trouble. To apply dynamic relocations
ld.so will make the text segment writable. On most systems this will
make the text segment non-executable, which will then result in a
segfault when ld.so tries to run ifunc resolvers when applying
relocations against ifuncs.
This patch teaches PowerPC ld to detect the situation, and warn.

bsd-uthread: Use ptid from regcache instead of inferior_ptid
This is one of the rare to_fetch/store_registers implementations that will
still rely (for now) on inferior_ptid (because of the memory read/write

be able to remove it when we make the memory operations accept the ptid as a
parameter.

PR remote/21188: Fix remote serial timeout
As Gareth McMullin <gareth@blacksphere.co.nz> reports at
<https://sourceware.org/ml/gdb-patches/2017-02/msg00560.html>, the
timeout mechanism in ser-unix.c was broken by commit 048094acc
("target remote: Don't rely on immediate_quit (introduce quit
handlers)").
Instead of applying a local fix, and since we now finally always use
interrupt_select [1], let's get rid of hardwire_readchar entirely, and
use ser_base_readchar instead, which has similar timeout handling,
except for the bug.
Smoke tested with:
$ socat -d -d pty,raw,echo=0 pty,raw,echo=0
2017/03/14 14:08:13 socat[4994] N PTY is /dev/pts/14
2017/03/14 14:08:13 socat[4994] N PTY is /dev/pts/15
2017/03/14 14:08:13 socat[4994] N starting data transfer loop with FDs [3,3] and [5,5]
$ gdbserver /dev/pts/14 PROG
$ gdb PROG -ex "tar rem /dev/pts/15"
and then a few continues/ctrl-c's, plus killing gdbserver and socat.

Big-endian targets: Don't ignore offset into DW_OP_stack_value
Recently I fixed a bug that caused a DW_OP_implicit_pointer with non-zero
offset into a DW_OP_implicit_value to be handled incorrectly on big-endian
targets. GDB ignored the offset and copied the wrong bytes:
https://sourceware.org/ml/gdb-patches/2017-01/msg00251.html
But there is still a similar issue when a DW_OP_implicit_pointer points
into a DW_OP_stack_value instead; and again, the offset is ignored. There
is an important difference, though: While implicit values are treated like
blocks of data and anchored at the lowest-addressed byte, stack values
traditionally contain integer numbers and are anchored at the *least
significant* byte. Also, stack values do not come in varying sizes, but
are cut down appropriately when used. Thus, on big-endian targets the
scenario looks like this (higher addresses shown right):
|<- - - - - Stack value - - - - - - ->|
| |
|<- original object ->|
|
| offset ->|####|
^^^^
de-referenced
implicit pointer
(Note how the original object's size influences the position of the
de-referenced implicit pointer within the stack value. This is not the
case for little-endian targets, where the original object starts at offset
zero within the stack value.)
This patch implements the logic indicated in the above diagram and adds an
appropriate test case. A new function dwarf2_fetch_die_type_sect_off is
added; it is used for retrieving the original object's type, so its size
can be determined. That type is passed to dwarf2_evaluate_loc_desc_full
via a new parameter.
gdb/ChangeLog:
* dwarf2loc.c (indirect_synthetic_pointer): Get data type of
pointed-to DIE and pass it to dwarf2_evaluate_loc_desc_full.

inf-ptrace: Do not stop memory transfers after a single word
When inf_ptrace_xfer_partial performs a memory transfer via ptrace with
PT_READ_I, PT_WRITE_I (aka PTRACE_PEEKTEXT, PTRACE_POKETEXT), etc., then
it currently transfers at most one word. This behavior yields degraded
performance, particularly if the caller has significant preparation work
for each invocation. And indeed it has for writing, in
memory_xfer_partial in target.c, where all of the remaining data to be
transferred is copied to a temporary buffer each time, for breakpoint
shadow handling. Thus large writes have quadratic runtime and can take
hours.
Note: On GNU/Linux targets GDB usually does not use
inf_ptrace_xfer_partial for large memory transfers, but attempts a single
read/write from/to /proc/<pid>/mem instead. However, the kernel may
reject writes to /proc/<pid>/mem (such as kernels prior to 2.6.39), or
/proc may not be mounted. In both cases GDB falls back to the ptrace
mechanism.
This patch fixes the performance issue by attempting to fulfill the whole
transfer request in inf_ptrace_xfer_partial, using a loop around the
ptrace call.
gdb/ChangeLog:
PR gdb/21220
* inf-ptrace.c (inf_ptrace_xfer_partial): In "case
TARGET_OBJECT_MEMORY", extract the logic for ptrace peek/poke...
(inf_ptrace_peek_poke): ...here. New function. Now also loop

Add test name argument to get_valueof, get_integer_valueof and get_sizeof
An optional parameter TEST has been added to get_hexadecimal_valueof in commit:
https://sourceware.org/ml/gdb-patches/2016-06/msg00469.html
This patch adds a similar optional parameter to other related methods that
retrieve expression values: get_valueof, get_integer_valueof and get_sizeof.
Thus tests that evaluate same expression multiple times can provide custom
test names, ensuring that test names will be unique.

linux-nat: Exploit /proc/<pid>/mem for writing
So far linux_proc_xfer_partial refused to handle write requests. This is
still based on the assumption that the Linux kernel does not support
writes to /proc/<pid>/mem. That used to be true, but has changed with
Linux 2.6.39 released in May 2011.
This patch lifts this restriction and now exploits /proc/<pid>/mem for
writing to inferior memory as well, if possible.
gdb/ChangeLog:
* linux-nat.c (linux_proc_xfer_partial): Handle write operations
as well.

Add asserts in target_fetch/store_registers
We are currently assuming that regcache->ptid is equal to inferior_ptid
when we call target_fetch/store_registers. These asserts just validate
that assumption. Also, since the following patches will change target
code to use regcache->ptid instead of inferior_ptid, asserting that they
are the same should ensure that our changes don't have any unintended
consequences.

testsuite: Disable backslash_in_multi_line_command_test for old DejaGnus
I noticed that backslash_in_multi_line_command_test in
gdb.base/commands.exp failed on our RHEL6 servers. I traced it to the
old version of DejaGnu (1.4.4). I have found that instead of receiving
the expected:
"print \\\nargc\n"
gdb received:
"print argc\n"
thus breaking the test and its purpose. Versionof DejaGnu < 1.5 mess
up sending "\\\n", it somehow gets replaced with a space. I found that
the following commit in DejaGnu fixed the issue:
http://git.savannah.gnu.org/cgit/dejagnu.git/commit/lib/remote.exp?id=3f39294f5cd6802858838d3bcc0ccce847ae17f2
Even though the commit is almost 10 years old, the following release of
DejaGnu was only in 2013, which is why we still have systems with the
old code.
If the DejaGnu version is < 1.5, we just skip the test.
gdb/testsuite/ChangeLog:
* gdb.base/commands.exp (backslash_in_multi_line_command_test):
Skip for versions of DejaGnu < 1.5.

testsuite: Introduce dejagnu_version
The next patch will require checking the DejaGnu version. There is
already a test that does this,
gdb.threads/attach-many-short-lived-threads.exp. This patch introduces
a new procedure, dejagnu_version, and makes that test use it.
The version number is "right-padded" with zeroes, to make sure that we
always return a triplet (major, minor, patch).
The procedure does not consider the DejaGnu versions from git. For
example, if you used DejaGnu from its current master branch, the version
would be "1.6.1-git", meaning that 1.6.1 will be the next release. I
figured we'll cross that bridge when (and if) we get there.
gdb/testsuite/ChangeLog:
* lib/gdb.exp (dejagnu_version): New proc.
* gdb.threads/attach-many-short-lived-threads.exp (bad_dejagnu):
Use dejagnu_version.

Merge libiberty: Initialize d_printing in all cplus_demangle_fill_* functions.
While integrating the d_printing recursion guard change into gdb I
noticed we forgot to initialize the demangle_component d_printing
field in cplus_demangle_fill_{name,extended_operator,ctor,dtor}.
As is done in cplus_demangle_fill_{component,builtin_type,operator}.
It happened to work because in gcc all demangle_components were
allocated through d_make_empty. But gdb has its own allocation

c++/8218: Destructors w/arguments.
For a long time now, c++/8218 has noted that GDB is printing argument types
for destructors:
(gdb) ptype A
type = class A {
public:
~A(int);
}
This happens because cp_type_print_method_args doesn't ignore artificial
arguments. [It ignores the first `this' pointer because it simply skips
the first argument for any non-static function.]
This patch fixes this:
(gdb) ptype A
type = class A {
public:
~A();
}
I've adjusted gdb.cp/templates.exp to account for this and added a new
passing regexp.

ld: Track changes to default region LMA even for empty sections
Given a linker script fragment like this:
SECTIONS {
. = 0x1000;
.text : AT(0x100) { *(.text) }
.data : AT(0x200) { *(.data) }
.rodata : AT(0x300) { *(.rodata) }
}
and an input file containing sections, '.text', '.data.1', and
'.rodata', then we'd expect the linker to place '.text' and '.rodata' in
the obvious way, and the '.data.1' orphan section would be located after
the '.data' section (assuming similar section properties).
Further, I believe that the expectation would be that the LMA for the
orphan '.data.1' section would start from 0x200 (as there is no '.data'
content).
However, right now, the LMA for '.data.1' would be 0x101, following on
from the '.text' section, this is because the change in LMA for the
'.data' section is not noticed by the linker, if there's no content in
the '.data' section.
What can be even more confusing to a user (though the cause is obvious
once you understand what's going on) is that adding some content to
'.data' will cause the orphan '.data.1' to switch to an LMA based off of
0x200.
This commit changes the behaviour so that an empty section that is in
the default lma region, and sets its lma, will adjust the lma of the
default region, this change will then be reflected in following sections
within the default lma memory region.
There's a new test to cover this issue that passes on a range of
targets, however, some targets generate additional sections, or have
stricter memory region size requirements that make it harder to come
up with a generic pass pattern, that still tests the required
features. For now I've set the test to ignore these targets.

* ldlang.c (lang_size_sections_1): Shortcut loop only after
tracking changes to the default regions LMA.

ld: better handling of lma region for orphan sections
When picking an lma_region for an orphan section we currently create a
new lang_output_section_statement_type and then populate this with the
orphan section.
The problem is that the lang_output_section_statement_type has a prev
pointer that links back to the previous output section. For non-orphan
output sections, that are created in linker script order, the prev
pointer will point to the output section that appears previous in linker
script order, as you'd probably expect.
The problem is that orphan sections are placed after processing the
linker script, and so, in the case of an output section created for an
orphan input section, the prev pointer actually points to the last
output section created.
This causes some unexpected behaviour when the orphan section is not
placed after the last non-orphan section that was created.
For example, consider this linker script:
MEMORY {
TEXT : ORIGIN = 0x200, LENGTH = 0x10
RODATA : ORIGIN = 0x400, LENGTH = 0x10
}
SECTIONS {
.text : {*(.text) } AT>TEXT
.data : AT(0x300) { *(.data) }
.rodata : { *(.rodata) } AT>RODATA
}
If we are processing an orphan section '.data.1' and decide to place
this after '.data', then the output section created will have a prev
pointer that references the '.rodata' output section. The result of
this is that '.data.1' will actually be assigned to the RODATA lma
region, which is probably not the expected behaviour.
The reason why '.data.1' is placed into the lma region of the '.rodata'
section is that lma region propagation is done at the time we create the
output section, based on the previous output section pointer, which is
really just a last-output-section-created pointer at that point in time,
though the prev point is fixed up later to reflect the true order of the
output sections.
The solution I propose in this commit is to move the propagation of lma
regions into a separate pass of the linker, rather than performing this
as part of the enter/exit of output sections during linker script
parsing.
During this later phase we have all of the output sections to hand, and
the prev/next points have been fixed up by this point to reflect the
actual placement ordering.
There's a new test to cover this issue that passes on a range of
targets, however, some targets generate additional sections, or have
stricter memory region size requirements that make it harder to come
up with a generic pass pattern, that still tests the required
features. For now I've set the test to ignore these targets.

ld: Orphan section documentation
Make more explicit mention of the fact that orphan sections can cause a
new output section to be created. Though this information is clearly
implied in the manual it might not be clear enough.
A user _might_ (incorrectly) think that orphan sections can only be
inserted into an existing output section.

X86: Add pseudo prefixes to control encoding
Many x86 instructions have more than one encodings. Assembler picks
the default one, usually the shortest one. Although the ".s", ".d8"
and ".d32" suffixes can be used to swap register operands or specify
displacement size, they aren't very flexible. This patch adds pseudo
prefixes, {xxx}, to control instruction encoding. The available
pseudo prefixes are {disp8}, {disp32}, {load}, {store}, {vex2}, {vex3}
and {evex}. Pseudo prefixes are preferred over the ".s", ".d8" and
".d32" suffixes, which are deprecated.

Update -maltivec and -mvsx options to only enable their oldest instructions.
Currently, the -maltivec and -mvsx GAS options enable *all* of the altivec
and vsx instructions respecitively that have ever been added. This is in
constract to GCC's -maltivec and -mvsx options, which only enable the oldest
(ie, first) set of altivec and vsx instructions. This patch changes GAS to
mimic GCC's behaviour with respect to -maltivec and -mvsx and it solves a
problem with trying to assemble the lxvx instruction which is different
between POWER8 and POWER9.

Fix PR18360 - internal error when using "interrupt -a"
If you do "interrupt -a" just while some thread is stepping over a
breakpoint, gdb trips on an internal error.
The test added by this patch manages to trigger this consistently by
spawning a few threads that are constantly tripping on a conditional
breakpoint whose condition always evaluates to false. With current
gdb, you get:
~~~
interrupt -a
.../src/gdb/inline-frame.c:343: internal-error: void skip_inline_frames(ptid_t): Assertion `find_inline_frame_state (ptid) == NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) FAIL: gdb.threads/interrupt-while-step-over.exp: displaced-stepping=on: iter=0: interrupt -a (GDB internal error)
[...]
.../src/gdb/inline-frame.c:343: internal-error: void skip_inline_frames(ptid_t): Assertion `find_inline_frame_state (ptid) == NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) FAIL: gdb.threads/interrupt-while-step-over.exp: displaced-stepping=off: iter=0: wait for stops (GDB internal error)
~~~
The assertion triggers because we're processing a stop for a thread
that had already stopped before and thus had already its inline-frame
state filled in.
Calling handle_inferior_event_1 directly within a
"thread_stop_requested" observer is something that I've wanted to get
rid of before, for being fragile. Nowadays, infrun is aware of
threads with pending events, so we can use that instead, and let the
normal fetch_inferior_event -> handle_inferior_event code path handle
the forced stop.
The change to finish_step_over is necessary because sometimes a thread
that was told to PTRACE_SINGLESTEP reports back a SIGSTOP instead of a
SIGTRAP (i.e., we tell it to single-step, and then interrupt it quick
enough that on the kernel side the thread dequeues the SIGTOP before
ever having had a chance of executing the instruction to be stepped).
SIGSTOP gets translated to a GDB_SIGNAL_0. And then finish_step_over
would miss calling clear_step_over_info, and thus miss restarting the
other threads (which in this case of threads with pending events,
means setting their "resumed" flag, so their pending events can be
consumed).
And now that we always restart threads in finish_step_over, we no
longer need to do that in handle_signal_stop.
Tested on x86_64 Fedora 23, native and gdbserver.

Fix PR 21218: GDB dumps core when escaping newline in multi-line command
With commit 3b12939dfc2399 ("Replace the sync_execution global with a
new enum prompt_state tristate"), GDB started aborting if you try
splitting an input line with a continuation char (backslash) while in
a multi-line command:
(gdb) commands
Type commands for breakpoint(s) 1, one per line.
End with a line saying just "end".
>print \
(gdb) 1 # note "(gdb)" incorrectly printed here.
>end
readline: readline_callback_read_char() called with no handler!
$
That abort is actually a symptom of an old problem introduced when
gdb_readline_wrapper was rewritten to use asynchronous readline, back
in 2007. Note how the "(gdb)" prompt is printed above in the "(gdb)
1" line. Clearly it shouldn't be there, but it already was before the
commit mentioned above. Fixing that also fixes the readline abort
shown above.
The problem starts when command_line_input passes a NULL prompt to
gdb_readline_wrapper when it finds previous incomplete input due to a
backslash, trying to fetch more input without printing another ">"
secondary prompt. That itself should not be a problem, because
passing NULL to gdb_readline_wrapper has the same meaning as passing a
pointer to empty string, since gdb_readline_wrapper exposes the same
interface as 'readline(char *)'. However, gdb_readline_wrapper passes
the prompt argument directly to display_gdb_prompt, and for the
latter, a NULL prompt argument has a different meaning - it requests
printing the primary prompt.
Before commit 782a7b8ef9c096 (which rewrote gdb_readline_wrapper to
use asynchronous readline), GDB behaved like this:
(gdb) commands
[....]
>print \
1
>end
(gdb)
The above is what this commit restores GDB back to.
New test included.

Fix PR tui/21216: TUI line breaks regression
Commit d7e747318f4d04 ("Eliminate make_cleanup_ui_file_delete / make
ui_file a class hierarchy") regressed the TUI's command window.
Newlines miss doing a "carriage return", resulting in output like:
~~~~~~~~~~~~~~~~~~
(gdb) helpList of classes of commands:
aliases -- Aliases of other commands
breakpoints -- Making program stop at certain points
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Before the commit mentioned above, the default ui_file->to_write
implementation had a hack that would defer into the ui_file->to_fputs
method. The TUI's ui_file did not implement the to_write method, so
all writes would end up going to the ncurses window via tui_file_fputs
-> tui_puts.
After the commit above, the hack is gone, but the TUI's ui_file still
does not implement the ui_file::write method. Since tui_file inherits
from stdio_file, writing to a tui_file ends up doing fwrite on the
FILE stream the TUI is "associated" with, via stdio_file::write,
instead of writing to the ncurses window.
The fix is to have tui_file override the "write" method.

Fix "layout reg" crash
Commit d7e747318f4d04 ("Eliminate make_cleanup_ui_file_delete / make
ui_file a class hierarchy") introduced a problem when using "layout
regs", that leads gdb to crash when issuing:
./gdb ./a.out -ex 'layout regs' -ex start
From the backtrace, it's caused by this 'delete' on tui_restore_gdbout():

714 delete gdb_stdout;
The problem is simply that the commit mentioned above made the ui_file
that gdb_stdout is temporarily set to be a stack-allocated
string_file, while before it used to be a heap-allocated ui_file. The
fix is simply to remove the now-incorrect delete.
New test included, which exercises enabling all TUI layouts, with and
without execution. (This particular crash only triggers with
execution.)

amd64-mpx: initialize BND register before performing inferior calls.
This patch initializes the BND registers before executing the inferior
call. BND registers can be in arbitrary values at the moment of the
inferior call. In case the function being called uses as part of the
parameters BND register, e.g. when passing a pointer as parameter, the
current value of the register will be used. This can cause boundary
violations that are not due to a real bug or even desired by the user.
In this sense the best to be done is set the BND registers to allow
access to the whole memory, i.e. initialized state, before pushing the
inferior call.

Certain insns have restrictions on fields. For example, the insn

Putting the name, comp_dir and producer strings in the .debug_str section

GAS: Fix bogus "attempt to move .org backwards" relaxation errors
Fix a commit 6afe8e98a664 ("internal error for backwards .org"),
<https://www.sourceware.org/ml/binutils/2008-06/msg00212.html>,
GAS regression that caused legitimate code to fail assembly with an
"attempt to move .org backwards" error.
For example with the `mips-linux' target we get:
$ cat org.s
.set mips16
la $2, foo
.org 0x1000
.align 2
foo:
.half 0
$ as -o org.o org.s
org.s: Assembler messages:
org.s:3: Error: attempt to move .org backwards
$
where the location pointer is obviously not moved backwards with `.org'.
The cause is positive `stretch' in relaxation due to a PC-relative ADDIU
instruction (produced from the LA macro used) getting expanded from 2 to
4 bytes as `foo' is noticed to be out of range for the short encoding.
This in turn triggers logic in `relax_segment' which concludes in the
processing of an `rs_org' frag produced that the location pointer is
moved backwards while in fact only the amount to space forward to the
location requested has shrunk, resulting in a negative growth of the
frag.
Correct the bad logic then and instead verify that the fixed part of an
`rs_org' frag has not overrun the location requested, as per the comment
already included with the error message:
/* Growth may be negative, but variable part of frag
cannot have fewer than 0 chars. That is, we can't
.org backwards. */
which accurately describes the regression scenario. Move the comment
ahead the conditional noted, for clarity.
Add generic and MIPS test cases for the `.org' pseudo-op, including the
test case discussed though not integrated with the offending commit in
particular, adjusted to work across all targets.

x86: fix handling of 64-bit operand size VPCMPESTR{I,M}
Just like REX.W affects operand size of the implicit rAX/rDX inputs to
PCMPESTR{I,M}, VEX.W does for VPCMPESTR{I,M}. Allow Q or L suffixes on
the instructions.
Similarly the disassembler needs to be adjusted to no longer require
VEX.W to be zero for the instructions to be valid, and to emit proper
suffixes.
Note, however, that this doesn't address the problem of there being no
way to control (at least) {,E}VEX.W for 32- or 16-bit code. Nor does it
address the problem of the many WIG instructions not getting properly
disassembled when VEX.W=1.

Nios2 dynobj handling fixes
A number of places in elf32-nios.c created dynamic sections but didn't
set the hash table dynobj. That meant we could have duplicate dynamic
sections connected to a number of bfds, so size_dynamic_sections
didn't properly discard or allocate contents.
Also, the entire set of dynamic sections was created in check_relocs
on seeing GOT relocs, when only .got related sections are needed,
probably done to hide segfaults later in finish_dynamic_sections.
The patch fixes these issues and makes the assembler emit errors when
nios2 lacks the necessary pc-relative relocs for subtraction
expressions, rather than silently generating bad code.
eg. ld-elf/merge. I've also tidied uses of elf32_nios2_hash_table and
elf_hash_table.

PowerPC addpcis fix
This came up because I was looking at ld/tmpdir/addpcis.o and noticed
the odd addends on REL16DX_HA. They ought to both be -4. The error
crept in due REL16DX_HA howto being pc-relative (as indeed it should
be), and code at gas/write.c:1001 after this comment
/* Make it pc-relative. If the back-end code has not
selected a pc-relative reloc, cancel the adjustment
we do later on all pc-relative relocs. */
*not* cancelling the pc-relative adjustment. So I've made a dummy
non-relative split reloc so that the generic code handles this, rather
than attempting to add hacks later in md_apply_fix which would not be
very robust. Having the new internal reloc also makes it easy to
support
addpcis rx,sym@ha
as an equivalent to
addpcis rx,(sym-0f)@ha
0:
The patch also fixes overflow checking, which must test whether the
addi will overflow too since @l relocs don't have any overflow check.
Lastly, since I was poking at md_apply_fix, I arranged to have the
generic gas/write.c code emit errors for subtraction expressions where
we lack reloc support.

Don't make dynamic .data.rel.ro SEC_READONLY
I'd made this dynamic section read-only so a flag test distinguished
it from .dynbss, but like any other .data.rel.ro section it really
should be marked read-write. (It is read-only after relocation, not
before.) When using the standard linker scripts this usually doesn't
matter since the output section is among other read-write sections and
not page aligned. However, it might matter in the extraordinary case
of the dynamic section being the only .data.rel.ro section with the
output section just happening to be page aligned and a multiple of a
page in size. In that case the output section would be read-only, and
live it its own read-only PT_LOAD segment, which is incorrect.

MIPS/BFD: Also handle `jalr $0, $25' with R_MIPS_JALR
Interpret the `jalr $0, $25' instruction encoding with an R_MIPS_JALR
relocation attached as an alias to `jr $25' and convert the jump to an
equivalent branch where possible, consequently covering the MIPSr6
architecture for the purpose of this optimization too.
