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.

/* This provides an extremely minimal setjmp/longjmp facility, in
|
|
which only the host's integer registers are saved/restored. Or at
|
|
least, that is the minimal guaranteed functionality.
|
|
|
|
Until Apr 2011 we used __builtin_setjmp and __builtin_longjmp, but
|
|
it appears that that is not always correctly implemented. See
|
|
https://bugs.kde.org/show_bug.cgi?id=259977. So this module wraps
|
|
those functions up and facilitates replacing them with our own
|
|
implementations where necessary.

/* Don't use jmp_buf, __builtin_setjmp or __builtin_longjmp directly.
|
|
They don't always work reliably. Instead use these macros, which
|
|
provide the opportunity to supply alternative implementations as
|
|
necessary.
|
|
|
|
Note that the abstraction is done with macros (ick) rather than
|
|
functions and typedefs, since wrapping __builtin_setjmp up in a
|
|
second function (eg, VG_(minimal_setjmp)) doesn't seem to work for
|
|
whatever reason -- returns via a VG_(minimal_longjmp) go wrong.
|
|
|
|
VG_MINIMAL_SETJMP stores the current integer register state in the
|
|
supplied argument, and returns zero. VG_MINIMAL_LONGJMP resumes
|
|
with the previously saved state, and returns a nonzero, word-sized
|
|
value. The caller must test all bits of the value in order to make
|
|
a zero/non-zero determination.
