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.

* better handle error recovery when calling remote_desc_activity
(avoid exhausting safe fd range)
* fix small error in m_gdbserver/README_DEVELOPERS
* implemented mknod and poll syscall on mknodat and ppoll
(mknod and poll are not directly supported on arm64)
* implement or fix various gdbsrv specific things needed for arm64
* changed assert condition in aspacemgr to VKI_SHMLBA >= VKI_PAGE_SIZE
With these changes, gdbserver integration seems to be basically working.
However, when breakpoints are placed or removed, discard_translations
causes an assert as the unchain has not been implemented yet for arm64 :
--1118:1:gdbsrv remove software_breakpoint at addr 0x400DE74 0x400DE74: _dl_debug_state (in /usr/lib64/ld-2.17.so)
--1118:2:transtab discard_translations(0x400de74, 2) req by m_gdbserver breakpoint remove
--1118:2:transtab FAST, ec = 27

What remains to be done:
* arm64 xml register description files (allowing shadow registers to be looked at).
* ptrace invoker : currently disabled for both arm and arm64
* cpsr transfer to/from gdb to be looked at (see also arm equivalent code)

* Addition of a function to compute size of buffer needed for VG_(mkstemp)
* Use it to dimension buffers for all VG_(mkstemp) calls.

Necessary changes to Valgrind to support MIPS64LE on Linux.
Minor cleanup/style changes embedded in the patch as well.
The change corresponds to r2687 in VEX.

Bug caused by the following problem:
for each mmap, Valgrind reads the 1st 1024 bytes to detect
if this is an mmap-ed file containing debug info to decode.
Reading this 1Kb is done with VG_(pread). VG_(pread) should be
the equivalent of syscall pread but on linux, it is implemented as
a seek+read.
The patch implements VG_(pread) in terms of the underlying pread syscall.
Test mmap_fcntl_bug.c completed to also verify the fd current position
before and after the mmap.
tested on linux x86/amd64/ppc32/ppc64/s390.

To that effect observe the environment variable TMPDIR. If defined,
its value takes precedence over VG_TMPDIR.
Because the directory name is no longer a compile time constant,
VG_(err_config_error) was changed to take a variable argument list.
Fixes#267020.

I tried using 'svn merge' to do the merge but it did a terrible job and
there were bazillions of conflicts. So instead I just took the diff between
the branch and trunk at r10155, applied the diff to the trunk, 'svn add'ed
the added files (no files needed to be 'svn remove'd) and committed.

that are memory offsets) with PtrdiffT; OffT should only be used for file
sizes and offsets.
Change Off64T from a ULong to a Long, as it should be. Replace some uses
of ULong in the address space manager with Off64T to match.
Also add a comment explaining the meanings of the basic types like Addr,
OffT, SizeT, etc.
Also fix the prototype for VG_(pread) -- the last arg is an OffT, not an
Int.
