On both Solaris 9/x86 and 32-bit Linux/x86, g++.dg/ext/vector26.C FAILs
like this:
FAIL: g++.dg/ext/vector26.C -std=c++11 (test for excess errors)
Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/ext/vector26.C:6:13: warning: M
MX vector argument without MMX enabled changes the ABI [enabled by default]
Like vector2.C, this can be avoided by compiling with -mmmx for 32-bit
x86. The following patch does just that.
Tested with the appropriate runtest invocations on i386-pc-solaris2.9,
i386-pc-solaris2.10, i686-unknown-linux-gnu, and
x86_64-unknown-linux-gnu. Ok for mainline?
