powerpc64: Always restore TOC on longjmp [BZ #21895]
This patch changes longjmp to always restore the TOC pointer (r2 register) to the caller frame on powerpc64 and powerpc64le. This is related to bug 21895 that reports a situation where you have a static longjmp to a shared object file. [BZ #21895] * sysdeps/powerpc/powerpc64/__longjmp-common.S: Remove condition code for restoring r2 in longjmp. * sysdeps/powerpc/powerpc64/Makefile: Added tst-setjmp-bug21895-static to test list. Added rules to build test tst-setjmp-bug21895-static. Added module setjmp-bug21895 and rules to build a shared object from it. * sysdeps/powerpc/powerpc64/setjmp-bug21895.c: New test file. * sysdeps/powerpc/powerpc64/tst-setjmp-bug21895-static.c: New test file.
