* configure.in support
* new supp file darwin11.supp
* comment out many intercepts in mc_replace_strmem.c and
vg_replace_malloc.c that are apparently unnecessary for Darwin
* add minimal handling for the following new syscalls and mach traps:
mach_port_set_context
task_get_exception_ports
getaudit_addr
psynch_mutexwait
psynch_mutexdrop
psynch_cvbroad
psynch_cvsignal
psynch_cvwait
psynch_rw_rdlock
psynch_rw_wrlock
psynch_rw_unlock
psynch_cvclrprepost
* wqthread_hijack on amd64-darwin: deal with
tst->os_state.pthread having an apparently different offset,
which caused an assertion failure
* m_debuginfo: for 32 bit processes on Lion, use the DebugInfoFSM
cleanup added in r12041/12042 to handle apparently new dyld
behaviour, which is to map text areas r-- first and only
vm_protect them later to r-x.
The following cleanups remain to be done
* remove apparently pointless, commented out wrapper macro
invokations in mc_replace_strmem.c, eg
//MEMMOVE(VG_Z_DYLD, memmove)
(or determine that they are still necessary, and uncomment)
* ditto in vg_replace_malloc.c, plus general VGO_darwin cleanups
there
* write proper syscall wrappers for
mach_port_set_context
task_get_exception_ports
getaudit_addr
psynch_mutexwait
psynch_mutexdrop
psynch_cvbroad
psynch_cvsignal
psynch_cvwait
psynch_rw_rdlock
psynch_rw_wrlock
psynch_rw_unlock
psynch_cvclrprepost
These are currently just no-ops and may be causing Memcheck to
report false undef-value errors
* figure out why it doesn't work properly unless built with gcc-4.2 on
Lion.
gcc-4.2 is the "normal" gcc (i686-apple-darwin11-gcc-4.2.1). Plain
gcc is the hybrid gcc-front-end clang-back-end thing
(i686-apple-darwin11-llvm-gcc-4.2). Whereas on Snow Leopard, plain
gcc is the normal gcc.
The symptoms of the failure are that wqthread_hijack in
syswrap-amd64-linux.c hits this /*NOTREACHED*/ vg_assert(0); right
at the end (you need a pretty complex threaded app to trigger this),
which makes me think that either ML_(wqthread_continue_NORETURN) or
call_on_new_stack_0_1 do return, which they are not expected to.
* figure out if some of the uninitialised value errors reported in
system libraries on are caused by Memcheck being confused by LLVM
generated code, as per bug #242137

perf_event_open some time after we added it, so correct the name
wherever it appears to match the current kernel source.
Also fixup the PRE handler to do the check correctly, using the
size field of the structure to work out how much data there is.

by Kirill Batuzov, batuzovk@ispras.ru. This fixes the main bug in
#222545. Temporarily breaks the build on all other platforms though.

AUXV at startup, rather than by trying to execute a Neon instruction
and seeing whether it SIGILLs. Apparently the latter is not a
reliable way to ascertain the presence of usable Neon support. Fixes

There were some easy-to-resolve conflicts.
Then I had to fix up coregrind/link_tool_exe*.in -- those files had been
added independently on both the trunk and the branch, AFAICT. I just
overwrote the trunk versions with the branch versions.

syscalls I've had the displeasure of encountering. Due to its
ridiculousness, the wrapper misses a PRE_MEM_WRITE check and so can result
in false positives. The POST_MEM_WRITE update is present, though, so it
shouldn't cause subsequent problems. Fixes bug 200760.

following improvements:
- Arch/OS/platform-specific files are now included/excluded via the
preprocessor, rather than via the build system. This is more consistent
(we use the pre-processor for small arch/OS/platform-specific chunks
within files) and makes the build system much simpler, as the sources for
all programs are the same on all platforms.
- Vast amounts of cut+paste Makefile.am code has been factored out. If a
new platform is implemented, you need to add 11 extra Makefile.am lines.
Previously it was over 100 lines.
- Vex has been autotoolised. Dependency checking now works in Vex (no more
incomplete builds). Parallel builds now also work. --with-vex no longer
works; it's little use and a pain to support. VEX/Makefile is still in
the Vex repository and gets overwritten at configure-time; it should
probably be renamed Makefile-gcc to avoid possible problems, such as
accidentally committing a generated Makefile. There's a bunch of hacky
copying to deal with the fact that autotools don't handle same-named files
in different directories. Julian plans to rename the files to avoid this
problem.
- Various small Makefile.am things have been made more standard automake
style, eg. the use of pkginclude/pkglib prefixes instead of rolling our
own.
- The existing five top-level Makefile.am include files have been
consolidated into three.
- Most Makefile.am files now are structured more clearly, with comment
headers separating sections, declarations relating to the same things next
to each other, better spacing and layout, etc.
- Removed the unused exp-ptrcheck/tests/x86 directory.
- Renamed some XML files.
- Factored out some duplicated dSYM handling code.
- Split auxprogs/ into auxprogs/ and mpi/, which allowed the resulting
Makefile.am files to be much more standard.
- Cleaned up m_coredump by merging a bunch of files that had been
overzealously separated.
The net result is 630 fewer lines of Makefile.am code, or 897 if you exclude
the added Makefile.vex.am, or 997 once the hacky file copying for Vex is
removed. And the build system is much simpler.

- Put Darwin syscall DECL_TEMPLATEs in syscall order.
- Removed the "sys_" prefix from Darwin-specific wrappers, it's not
necessary. Renamed a couple of other wrappers similarly.
- Removed the sys_fcntl64 Darwin wrapper, it was unused.
- Improved some code layout.
Overall this removes 6 "DDD"/"GrP" fixme comments.
