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)
Change-Id: Ic20b97a97b6d506c32322173bd8332d15c3a4555
openjdk appears to use ppc64/server/libjvm.so and not ppc64le/server/libjvm.so
Change-Id: Iff9e2e0ac9921b0d9d36a49fdcd2323d5dd124ee
(cherry picked from commit 632e4095ad92196480ad82cfa1f106c4c08ae1cc)
need to accept ppc64le as a lib64 using platform in ax_boost_base.m4
Change-Id: I86ef068661082addbd165629d3d6905695090a6b
(cherry picked from commit 2d48c52da712f8fa3c4a579494c824491afb8515)
linux_powerpc64le->linux_powerpc64_le to match dp_platform.cxx
Change-Id: Ib63e5a28d7ff12780a1051d94c5976244eab1814
(cherry picked from commit 2ced4d39cc1b8de233cd886d3ef991b3079500d2)
Related: rhbz#1125588 get as far as privateSnippetExecutor
Change-Id: Icc386083ecd9faefbedebbb9d2496a4eddfa0b2b
(cherry picked from commit 4c5bbbf059924f3aa24620a4cbbc35816978a606)
Related: rhbz#1125588 get to the end of cpp_mediate on ppc64le
Change-Id: Id3928ef5ac68ea13a7aa8723bc8b068ecf8075a0
(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
Change-Id: Ie56d148ebea7fcfc023cb7183bc97f09186e66b4
(cherry picked from commit 6396e18f4d49c24283b170310a1892db40c128d3)
