Subject: [PATCH] Resolves: rhbz#1125588 port LibreOffice to ppc64le
Related: rhbz#1125588 first steps for ppc64le
almost certainly won't get us too far, but a start
(cherry picked from commit 170109708e6a082252efba3d2f1726bbd82b6452)
openjdk appears to use ppc64/server/libjvm.so and not ppc64le/server/libjvm.so
(cherry picked from commit 632e4095ad92196480ad82cfa1f106c4c08ae1cc)
need to accept ppc64le as a lib64 using platform in ax_boost_base.m4
(cherry picked from commit 2d48c52da712f8fa3c4a579494c824491afb8515)
linux_powerpc64le->linux_powerpc64_le to match dp_platform.cxx
(cherry picked from commit 2ced4d39cc1b8de233cd886d3ef991b3079500d2)
Related: rhbz#1125588 get as far as privateSnippetExecutor
(cherry picked from commit 4c5bbbf059924f3aa24620a4cbbc35816978a606)
Related: rhbz#1125588 get to the end of cpp_mediate on ppc64le
(cherry picked from commit d8fcd8ca9af087e98a2f6d9cbcf6eb42cddd0c74)
Related: rhbz#1125588 force existence of argument save area
ELFv2 ABI on ppc64 optimises stack allocation
(http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01149.html
so we're getting no argument save area
This now appears to pass the simple cases and onwards
to the tricky ones
(cherry picked from commit 6396e18f4d49c24283b170310a1892db40c128d3)
Related: rhbz#1125588 ppc64le has new struct passing rules
http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01145.html
http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01147.html
now we just fail instead of crash
