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.
