Hi!

The following patch fixes the gcc.dg ones and the excess errors in
vec-narrow-minmax-2.C.
vec-narrow-1.C still fails on ia32, dunno why (added at least -mmmx but it
didn't help, unlike x86_64 ia32 doesn't emulate MMX sized vectors in SSE2),
and the MIN_EXPR scans fail before/after on both x86_64 and ia32.
Tested on x86_64-linux with
GXX_TESTSUITE_STDS=98,11,14,17,20,23,26,29 make check-gcc check-g++
RUNTESTFLAGS="--target_board=unix\{-m64,-m32,-m32/-mno-sse/-mno-mmx\}
tree-ssa.exp='divmul-mod-1.c round-up-ior-1.c vec-mask-zero-1.c
vector-alignup-1.c' dg.exp='vec-narrow-minmax-2.C vec-narrow-1.C'"
Ok for trunk?

* gcc.dg/tree-ssa/divmul-mod-1.c: Add -Wno-psabi to dg-options.
* gcc.dg/tree-ssa/round-up-ior-1.c: Likewise.
* gcc.dg/tree-ssa/vec-mask-zero-1.c: Require vect_int effective
target. Add -Wno-psabi to dg-options and add -msse2 as
dg-additional-options on ia32.
* gcc.dg/tree-ssa/vector-alignup-1.c: Add -msse2 as
dg-additional-options on ia32.
* g++.dg/tree-ssa/vec-narrow-minmax-2.C: Add -Wno-psabi to dg-options.
* g++.dg/tree-ssa/vec-narrow-1.C: Likewise. Add -mmmx as
dg-additional-options on ia32.
