This commit is for Bugzilla 334834. The Bugzilla contains patch 2 of 3
to add PPC64 LE support. The other two patches can be found in Bugzillas
334384 and 334836.
POWER PC, add the functional Little Endian support, patch 2
The IBM POWER processor now supports both Big Endian and Little Endian.
The ABI for Little Endian also changes. Specifically, the function
descriptor is not used, the stack size changed, accessing the TOC
changed. Functions now have a local and a global entry point. Register
r2 contains the TOC for local calls and register r12 contains the TOC
for global calls. This patch makes the functional changes to the
Valgrind tool. The patch makes the changes needed for the
none/tests/ppc32 and none/tests/ppc64 Makefile.am. A number of the
ppc specific tests have Endian dependencies that are not fixed in
this patch. They are fixed in the next patch.
Per Julian's comments renamed coregrind/m_dispatch/dispatch-ppc64-linux.S
to coregrind/m_dispatch/dispatch-ppc64be-linux.S Created new file for LE
coregrind/m_dispatch/dispatch-ppc64le-linux.S. The same was done for
coregrind/m_syswrap/syscall-ppc-linux.S.

to add PPC64 LE support. The other two patches can be found in Bugzillas
334834 and 334836. The commit does not have a VEX commit associated with it.
POWER PC, add initial Little Endian support
The IBM POWER processor now supports both Big Endian and Little Endian.
This patch renames the #defines with the name ppc64 to ppc64be for the BE
specific code. This patch adds the Little Endian #define ppc64le to the
Additionally, a few functions are renamed to remove BE from the name if the
function is used by BE and LE. Functions that are BE specific have BE put
in the name.
The goals of this patch is to make sure #defines, function names and
variables consistently use PPC64/ppc64 if it refers to BE and LE,
PPC64BE/ppc64be if it is specific to BE, PPC64LE/ppc64le if it is LE
specific. The patch does not break the code for PPC64 Big Endian.
The test files memcheck/tests/atomic_incs.c, tests/power_insn_available.c
and tests/power_insn_available.c are also updated to the new #define
definition for PPC64 BE.

Enable vgdb ptrace invoker for aarch64.
This only works in non-bi arch mode. If ever aarch64+arm
are compiled bi-arch, then some more work is needed to have
a 64 bits vgdb able to ptrace invoke a 32 bits valgrind.
Note also that PTRACE_GETREGSET is defined on other platforms
(e.g. ppc64 fedora 18 defines it), but it is not used on
these platforms, as again, PTRACE_GETREGSET implies some
work for bi-arch to work properly.
So, on all platforms except arm64, we use PTRACE_GETREGS
or PTRACE_PEEKUSER.

vgdb must not transmit signals when gdbserver has been ptrace-invoked.
Most of the time, Valgrind masks async signals, and polls for such
signals at regular interval.
There is a very narrow range of code (around client syscall logic)
where such signals are unmasked (as they must be able to interrupt
syscalls).
This is the only range of code where Valgrind is expecting to
receive such a signal.
When gdbserver is ptraced invoked, Valgrind is artificially made
to jump out of this code portion. Signals are not masked.
When ptraceing valgrind, vgdb will get these signals but cannot
transmit them immediately, otherwise they arrive in range
of code where they are not expected (causing internal error
in syscall logic) and/or causing gdbserver syscalls to be
interrupted.
3 solutions to solve that were looked at:
1. have the gdbserver code masking signals "as quickly as possible".
Easy to implement, but this leaves still a small window
of code where signals are not masked and would cause a problem.
2. have vgdb setting the SIGMASK of valgrind before invoking
gdbserver.
This would be easy to implement, but changing the SIGMASK
of the ptrace-d process is only available on very recent kernels.
3. have vgdb queuing signals, and only transmitting them once
gdbserver invocation is finished.
This 3rd solution has been implemented.

Fix 326462 Refactor vgdb to isolate invoker stuff into separate module
vgdb.c contained (conditionally compiled) "invoker" code to have ptrace syscalls
used to allow gdb/vgdb to connect to a valgrind process blocked in a syscall.
This "invoker" code is ptrace based.
Not all platforms are using ptrace.
=> refactor vgdb so as allow invoker code to be added more cleanly
for non ptrace based platforms (e.g. Darwin, Solaris).
* add file vgdb.h for:
- definition of the vgdb-invoker interface
- common declarations between vgdb.c and vgdb-invoker implementations
* move ptrace related code from vgdb.c to new file vgdb-invoker-ptrace.c
* new file vgdb-invoker-none.c containing an empty invoker implementation
used on platforms that do not (yet) have a invoker implementation
(e.g. android and darwin).
* modified Makefile.am to use one of the vgdb-invoker-*.c file depending
on the platform.
* small changes related to changing ptraceinvoker to invoker in various files:
gdbserver_tests/make_local_links, gdbserver_tests/nlcontrolc.vgtest,
gdbserver_tests/mcinvokeRU.vgtest, gdbserver_tests/nlsigvgdb.vgtest
gdbserver_tests/mcinvokeWS.vgtest, coregrind/m_gdbserver/README_DEVELOPERS
