(from bug 385408 comment 0):
Valgrind currently lacks support for the z/Architecture vector "support"
instructions introduced with z13. These are documented in the
z/Architecture Principles of Operation, Eleventh Edition (March, 2015),
chapter 21: "Vector Overview and Support Instructions".
This implements a fallback LL/SC implementation as described in bug 344524.
Valgrind side changes:
* Command line plumbing for --sim-hints=fallback-llsc
* memcheck: handle new arm64 guest state in memcheck/mc_machine.c
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@16309
The test suite support for the Power PC ISA 3.0 instructions added in
VEX commit 3222 is added in this commit.
Note, this is part 4 of 5. The NEWS file will be updated when the ISA 3.0
support is complete.

we now similarly count on luch for GS

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.

Necessary changes to Valgrind to support MIPS64LE on Linux.
Minor cleanup/style changes embedded in the patch as well.

This patch adds test cases. Also adds some minor Memcheck
instrumentation tweaks necessitated by the IR changes.

* new files include/pub_tool_groupalloc.h and coregrind/m_groupalloc.c
implementing a group allocator (based on helgrind group alloc).
* include/Makefile.am coregrind/Makefile.am : added pub_tool_groupalloc.h
and m_groupalloc.c
* helgrind/libhb_core.c : use pub_tool_groupalloc.h/m_groupalloc.c
instead of the local implementation.
* include/pub_tool_oset.h coregrind/m_oset.c : new function
allowing to create an oset that will use a pool allocator.
new function allowing to clone an oset (so as to share the pool alloc)
* memcheck/tests/unit_oset.c drd/tests/unit_bitmap.c : modified
so that it compiles with the new m_oset.c
* memcheck/mc_main.c : use group alloc for MC_Chunk
memcheck/mc_include.h : declare the MC_Chunk group alloc
* memcheck/mc_main.c : use group alloc for the nodes of the secVBitTable OSet
* include/pub_tool_hashtable.h coregrind/m_hashtable.c : pass the free node
function in the VG_(HT_destruct).
(needed as the hashtable user can allocate a node with its own alloc,
the hash table destroy must be able to free the nodes with the user
own free).
* coregrind/m_gdbserver/m_gdbserver.c : pass free function to VG_(HT_destruct)
* memcheck/mc_replace_strmem.c memcheck/mc_machine.c
memcheck/mc_malloc_wrappers.c memcheck/mc_leakcheck.c
memcheck/mc_errors.c memcheck/mc_translate.c : new include needed
due to group alloc.
