Created attachment 6891
--> http://sourceware.org/bugzilla/attachment.cgi?id=6891
testcase with ifunc that fails on x86-64
This problem is not limited to AArch64. Attached is a testcase that fails on
x86-64 (and probably other arches as well). In this case, an IFUNC resolver
function clobbers xmm0, which is not saved/restored in _dl_runtime_resolve.
