I've now installed the patch to remove the obvious testsuite failures,
but it turned out that the ipa-icf-21.c testcase has further issues on

FAIL: gcc.dg/ipa/ipa-icf-21.c (test for excess errors)
Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.dg/ipa/ipa-icf-21.c:10:10: warning: SSE vector return without SSE enabled changes the ABI [-Wpsabi]
/var/gcc/regression/trunk/3.14.17-gcc-gas-gld-32/build/gcc/include/xmmintrin.h:909:1: error: inlining failed in call to always_inline '_mm_load1_ps': target specific option mismatch
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.dg/ipa/ipa-icf-21.c:10:10: error: called from here

The former can be cured by adding -Wno-psabi to dg-options, but I've no
idea what to do about the latter, especially since it doesn't occur on
