The new test FAILs on i686-linux, with the usual
FAIL: gcc.dg/vec-perm-lower.c (test for excess errors)
Excess errors:
.../gcc/testsuite/gcc.dg/vec-perm-lower.c:9:1: warning: SSE vector return
without SSE enabled changes the ABI [-Wpsabi]
.../gcc/testsuite/gcc.dg/vec-perm-lower.c:8:1: warning: MMX vector argument
without MMX enabled changes the ABI [-Wpsabi]
The following patch fixes that.
Tested on x86_64-linux with
make check-gcc
RUNTESTFLAGS='--target_board=unix/\{-m32,-m32/-mno-sse/-mno-mmx,-m64\}
dg.exp=vec-perm-lower.c'
which previously FAILed, now PASSes, ok for trunk?
