thread support broken on ppc-aix.
Thread support got broken when adding 64bit support on ppc-aix.
Upon digging further, I found that the following patch...
| * gdb_ptrace.h: Use ptrace64 instead of ptrace if HAVE_PTRACE64
| is defined.
| * rs6000-nat.c: Check for __ld_info64_ if compiling 64 BIT gdb.
| (rs6000_ptrace32): Call ptrace64 instead of ptrace if present.
| (rs6000_ptrace64): Call ptace64 instead of ptracex if present.
| * configure.ac: Check for ptrace64.
| * configure, config.in: Regenerate.
... is responsible for this regression:
(gdb) x /x &__n_pthreads
0xf06a8258 <__n_pthreads>: Cannot access memory at address 0xf06a8258
Prior to the patch, we have:
(gdb) x /x &__n_pthreads
0xf06a8258 <__n_pthreads>: 0x00000003
The problem occurs inside rs6000_ptrace32, while calling ptrace64.
The address is given to rs6000_ptrace32 as an "int *", while
ptrace64 takes a "long long". The cast causes the address to be
sign-extended, which results in GDB trying to read the wrong address.
This patch fixes the issue by casting the address to a "uintptr_t"
instead, and letting the compiler do the implicit conversion to
"long long" in the function call.
gdb/ChangeLog:
* rs6000-nat.c (rs6000_ptrace32): Cast "addr" to "uintptr_t"
instead of "long long" in call to ptrace64.

cleanup: use value_lazy_at instead of allocate_value_lazy/attribute setter
I came across a pattern used to construct a value in the following way:
struct value *val = allocate_value_lazy (type);
VALUE_LVAL (val) = lval_memory;
set_value_address (val, address);
Instead we fold the above call into:
value_at_lazy (type, addr);

* dwarf2loc.c (dwarf2_evaluate_loc_desc_full): Use value_at_lazy instead
of assembling value via allocate_value_lazy and attribute setter.

assembling value via allocate_value_lazy and attribute setter.
* valops.c (do_search_struct_field): Use value_at_lazy instead of

Add options to skip unavailable locals
This is the patch to add new option '--skip-unavailable' to MI
commands '-stack-list-{locals, arguments, variables}'. This patch
extends list_args_or_locals to add a new parameter 'skip_unavailable',
and don't list locals or arguments if values are unavailable and
'skip_unavailable' is true.
This is inspecting a trace frame (tfind mode), where only a few
locals have been collected.
-stack-list-locals, no switch vs new switch:
-stack-list-locals --simple-values
^done,locals=[{name="array",type="unsigned char [2]"},{name="i",type="int",value="<unavailable>"}]
-stack-list-locals --skip-unavailable --simple-values
^done,locals=[{name="array",type="unsigned char [2]"}]
-stack-list-arguments, no switch vs new switch:
-stack-list-arguments --simple-values
^done,stack-args=[frame={level="0",args=[{name="j",type="int",value="4"},{name="s",type="char *",value="<unavailable>"}]},frame={level="1",args=[]}]
-stack-list-arguments --skip-unavailable --simple-values
^done,stack-args=[frame={level="0",args=[{name="j",type="int",value="4"}]},frame={level="1",args=[]}]
-stack-list-variables, no switch vs new switch:
-stack-list-variables --simple-values
^done,variables=[{name="j",arg="1",type="int",value="4"},{name="s",arg="1",type="char *",value="<unavailable>"},{name="array",type="unsigned char [2]"},{name="i",type="int",value="<unavailable>"}]
-stack-list-variables --skip-unavailable --simple-values
^done,variables=[{name="j",arg="1",type="int",value="4"},{name="array",type="unsigned char [2]"}]
tests are added to test these new options.

remote.c: don't install a deprecated_xfer_memory hook.
There's no need for deprecated_xfer_memory nowadays. Memory access
goes through target_xfer_partial/TARGET_OBJECT_MEMORY, etc. In fact,
the remote target already handles that, and is deferring to the same
helpers the deprecated_xfer_memory hook is. Basically, only a few
adjustments to make these helper routines's interfaces closer to
target_xfer_partial's were necessary.
Tested on x86_64 Fedora 17 w/ gdbserver.

[Committing the `catch syscall' patch for ARM, from Samuel Bronson.]
This time, it passes all the tests and comes with a nearly complete
XML file (plus a script that can nearly regenerate the XML file).
(I elected to leave out __ARM_NR_cmpxchg, since it has dire warnings
to the effect that the only pieces of code that should be aware of it
are the implementation and the __kuser_cmpxchg code in entry-armv.S.)

fix dwz.exp on 32-bit targets
This fixes dwz.exp on 32-bit targets. It does so by introducing a new

introduce gdb_remote_download and finish parallel fixes in gdb.dwarf2
This finishes making gdb.dwarf2 parallel-safe.
To do this, this patch introduces a new gdb_remote_download proc, that
works somewhat differently in the one specific case where it matters:
for a copy to "host", if no destination was given, and the host is not
actually remote, then standard_output_file is used. In parallel mode
this guarantees that the resulting file will end up in a parallel-safe
location.

dwarf2_evaluate_loc_desc_full (frame #7) knows to handle
NOT_AVAILABLE_ERROR errors, but read_memory always throws
a generic error.
Presently, only the value machinery knows to handle unavailable
memory. We need to push the awareness down to the target_xfer layer,
making it return a finer grained error indication. We can only return
a generic -1 nowadays, which leaves the upper layers with no clue on
why the xfer failed. Use target_xfer_partial directly, rather than
propagating the error through target_read_memory so as to get a better
address to display in the error message.
(target_read_memory & friends build on top of target_read (thus the
target_xfer machinery), but turn all errors to EIO, an errno value. I
think this is a mistake, and we'd better convert all these to return a
target_xfer_error too, but that can be done separately. I looked
around a bit over memory_error calls, and the need to handle random
errno values, other than the EIOs gdb itself hardcodes, probably comes
(only) from deprecated_xfer_memory, which uses errno for error
indication, but I didn't look exhaustively. We should really get rid
of deprecated_xfer_memory and of passing down errno values as error
indication in target_read & friends methods).
Tested on x86_64 Fedora 17, native and gdbserver. Fixes the test in
the PR, which will be added to the testsuite later.

fix PR python/15816
This fixes PR python/15816.
The bug here is that python-selftest.exp can fail:
No symbol "RETURN_MASK_ALL" in current context.
RETURN_MASK_ALL is a macro, so if macros do not end up in the
debuginfo (very typical) then the test fails.
It seemed simplest to me to simply turn the RETURN_MASK_ defines into
enum constants. This way they end up in the debuginfo and all is

move gdbarch object from objfile to per-BFD
This moves the "gdbarch" field from the objfile into the BFD.
This field's value is derived from the BFD and is immutable over the
lifetime of the BFD. This makes it a reasonable candidate for pushing
into the per-BFD object.
This is part of the long-term objfile splitting project. In the long
run I think this patch will make it simpler to moves types from the
objfile to the per-BFD object; but the patch makes sense as a minor
cleanup by itself.

linux-nat.c: no need to block child signals so aggressively.
In http://sourceware.org/ml/gdb-patches/2013-08/msg00174.html , the
issue of child signal handling around ptrace option support discovery
being different between GDB and GDBserver came up.
I recalled adding these block_child_signals calls, and the "We don't
want those ptrace calls to be interrupted" comment, but not exactly
why. So I looked into it. My first guess is that I got confused.
The patch that added this
<http://sourceware.org/ml/gdb-patches/2009-04/msg00125.html> rewrote
the linux native async support completely, and the old async support
code had the SIGCHLD handler itself do waitpid, so in places that we'd
want a blocking waitpid, we'd have to have the signal handler blocked.
That was probably the mindset I had at the time. Anyway, whatever the
case, looks like I was wrong on the need for this blocking.
Given GDBserver doesn't block like this, I investigated why this is
currently needed on GDB but not on GDBserver.
I removed the block_child_signals (and restore) calls, and hacked
linux-nat.c to call linux_test_for_tracefork in a loop, like:
@@ -534,7 +534,10 @@ static int
linux_supports_tracefork (int pid)
{
if (linux_supports_tracefork_flag == -1)
- linux_test_for_tracefork (pid);
+ {
+ while (1)
+ linux_test_for_tracefork (pid);
+ }
return linux_supports_tracefork_flag;
}
Running the resulting GDB, I then saw bad things happening.
Specifically, I'd end up with a bunch of zombies, and eventually, the
machine would refuse to spawn new processes, claming insufficient
resources.
The issue is that linux_test_for_tracefork test forks, and has the
child fork again. If we don't block SIGCHLD on entry to the function,
the children will inherit SIGCHLD's action/disposition (meaning,
SIGCHLD will be unblocked in the child). When the first child forks
again a second child, and that child exits, the first child gets a
SIGCHLD. Now, when we try to wrap up for the whole options test, we
kill the first child, and collect the waitstatus. Here, when SIGCHLD
isn't blocked, GDB will first see the child reporting a stop with
SIGCHLD. gdbserver's ptrace options test does a PTRACE_KILL loop at
the end, which catches the SIGCHLD, and retries the kill. The GDB
version did not do that. So the GDB version would proceed, leaving
the child zombie (until GDB exists), as nothing collected its final
waitstatus.
So this patch makes the GDB version of linux_test_for_tracefork do the
exact same as the GDBserver version, removes all this unnecessary
blocking throughout, and adds a couple comments at places that do need
it -- namely: places where we'll use sleep with sigsuspend; and
linux_async_pipe, as that destroys the pipe the signal handler
touches.
Tested on x86_64 Fedora 17, sync and async.

src-release: Strip "-cvs" from GDB source dir and tarball.
The nightly snapshots we have been creating in the past did not
include the "-cvs" suffix at the end of the version number. Snapshot
packaging started breaking ever since GDB switched to using BFD's
version number. Things got partially fixed with the previous change
to this file, but the change missed the fact that the "-cvs" suffix
in the tarball name (Eg: gdb-7.6.50-20130816-cvs.tar) is undesirable.
This patch removes it.
ChangeLog:
* src-release (VER): When using $(TOOL)/common/create-version.sh,
strip the "-cvs" suffix from the version number if present.

move some static thread state into remote_state
This moves a few static variables from thread-info functions into
remote_state. Pedro said on irc that these functions implement the
ancient thread-discovery method and that he wouldn't be surprised if
they had rotted; nevertheless it seems safer to me to make them
explicitly per-remote.
This necessitated moving a couple of macros and a typedef earlier in
the file.
