Fix all the places where gcc complains about casts from pointers
(presumably 64 bit) to integers of different size (in this case,
32-bit int). This makes it compile cleanly on 64-bit AIX and also
means it doesn't crash :-)

Use 'ctr' rather than 'lr' for indirect jumps, so as not to trash the
branch predictor(s) for returns from generated code. Makes a big
difference on ppc970 (and POWER4).

- add extra fields to ThreadOSState to make thread cancellation sort-of
work on AIX5
- add function VG_(count_runnable_threads)
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6288
AIX5 support. No changes in logic; just better factorisation of what
is already here.
- add AIX definitions for VG_UCONTEXT_INSTR_PTR et al
- add abstractions VKI_SIGINFO_si_addr and VKI_SIGINFO_si_pid
to enable the rest of the code to be uniform
- track other minor changes: SysRes, VG_(am_find_nsegment)
constness, rearrangement of VG_(sigtimedwait).
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6287
Track SysRes change, and remove unused stuff in header. Perhaps
this should be folded into m_initimg in the fullness of time.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6286
Generalise the machinery developed for function intercepts/wrapping
ppc64-linux, in which we have to deal with the big extra complexity
resulting from TOC pointers. This generalises it to work in 32-bit
mode too.
Add helpers to deal with AIX stack redzones.
Track VG_(am_find_nsegment) constness change and other minor
changes to the m_aspacemgr interface.
(All platforms): use the new VexMiscInfo structure to tell VEX about
host and guest ABI conventions.
This module could do with further tidying up and documentation.

Minor adjustments to the scheduler, mostly cosmetic.
- rename VG_(kill_thread) to VG_(get_thread_out_of_syscall), which
is what it actually does.
- Remove 'semaphore' terminology in places and use 'lock' instead.
- Give an extra 'HChar* who' arg to VG_(set_running) and
VG_(set_sleeping), which is printed when --trace-sched=yes.
This makes it easier to make sense of lock ownership changes
from the debug output.
- various other improvements to debug printing
- add a kludge to encourage the AIX scheduler to switch threads
more often when more than one is runnable (am not claiming to
understand this); otherwise CPU starvation can appear to happen
- more assertions in sema.c (the pipe-based lock); cycle the token
through 'A' to 'Z' to make strace/truss output more understandable;
fix longstanding bug wherein sema_down() tries to read two bytes
even though sema_up only writes one.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6281
Minor enhancements, including dealing with 6-digit PIDs, dealing with
object names of the form "foo.a(bar.o)", and removing debuglog level
zero output.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6278
- track SysRes changes
- track VG_(am_find_nsegment) const-ness change
- increase number of client syscall args supported from 6 to 8
- simplify type SyscallStatus. Simply hold a copy of the SysRes
for the syscall rather than have this be a data structure
incorporating something very similar to the fields of a SysRes,
and more besides. Change various macros in priv_types_n_macros.h
to match.
- syswrap-main.c: instantiate the various impedance-matching
functions for AIX.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6276
- Minor changes for mpxlc
- kludge; add option "initkludge" to cause PMPI_Init to return
&mpiwrap_walk_type_EXTERNALLY_VISIBLE
and adjust mpiwrap_type_test.c accordingly
and also add an export script so that libmpiwrap.so is built
correctly on AIX5 (r????).
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6275
Convert some VG_ names (global visibility) into ML_s (module scope).
and also handle Z-encoded 'ZL' == ( and 'ZR' == )
for intercept/wrapper fn names
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6274
Track SysRes change; support bigpage allocation on AIX; make the
client-arena superblocks much bigger on AIX.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6273
Accumulate statistics about the number of searches in the errors and
suppressions lists, and rearrange the suppressions list when searching
to reduce cost of future searches.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6271
Inline stackPush and stackPop and placate gcc's resulting concerns
about uninitialised variables.
and also change ownership.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6270
Minor changes for redirection on AIX. The only significant change is
that it now checks for, warns about and disallows, attempts to
redirect to, or wrap with, a function for which no TOC pointer can be
found, since that would be really asking for trouble (a segfault).
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6269
Change the SysRes type so as to represent both the error value and the
non-error result at the same time.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6268
- AIX implementations of various stuff, nothing surprising.
- For all platforms: make VG_(read) and VG_(write) return (negative)
actual error values rather than producing -1 for all failures.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6267
Changes to support XCOFF:
- allow modules to have 'member names' as well as file names. A member
name is a "foo.o" name inside a "bar.a"; necessary as AIX
keeps all its dynamic libraries in .a files.
- rename the type RiLoc to DiLoc (this holds a line number indication).
No idea why it was called RiLoc in the first place.
- trace changes in type SysRes
- implement VG_(di_aix5_notify_segchange)
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6266
Interface changes for m_debuginfo:
- new fn VG_(di_aix5_notify_segchange) to notify XCOFF loads/unloads
- new fn VG_(lookup_symbol_SLOW) for looking up the address of a fn
given its name and soname
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6265
New option --sym-offsets=yes|no [no], which causes all symbols to be
shown in the form 'name+offset'. Mostly useful for debugging Valgrind
itself.
Also move command-line-error functions from m_main into m_options.
[Will move them back shortly.]
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6263
Extensions for unwinding stacks on ppc32-aix5 and ppc64-aix5. Also,
extend the mechanism developed for ppc64-linux for fishing return
addresses out of the thread's redirection-stack when needed.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6261
Get rid of VG_(sigtimedwait) and replace it a simpler version,
VG_(sigtimedwait_zero), which polls for signals and returns
immediately. AIX doesn't have a sigtimedwait syscall, so in that case
try and implement VG_(sigtimedwait_zero) using various other signal
syscalls.
