Here's what I've checked in after i686-unknown-linux-gnu,
x86_64-unknown-linux-gnu, and i386-pc-solaris2.11 testing:
2014-10-24 Rainer Orth <r...@cebitec.uni-bielefeld.de>
* gcc.dg/pr63594-1.c: Apply -mno-mmx to all i?86-*-* and x86_64-*-*
targets.
* gcc.dg/pr63594-2.c: Likewise.

This seems to be the same issue as PR target/61535.
