Hi
I want to port r175009 from trunk to google/gcc-4_6 since it fixed 3 dejagnu
failures for arm backend.
Tested on x86-64 with
make check-gcc RUNTESTFLAGS="vect.exp"
Tested on arm qemu with
make check-gcc RUNTESTFLAGS="--target_board=arm-sim/thumb/arch=armv7-a vect.exp"
make check-gcc RUNTESTFLAGS="--target_board=arm-sim/arch=armv7-a vect.exp"
OK for google/gcc-4_6?
thanks

Backport r175009 from trunk.
2011-06-14 Ira Rosen <ira.ro...@linaro.org>
* gcc.dg/vect/vect-16.c: Rename to...
* gcc.dg/vect/no-fast-math-vect16.c: ...this.
* gcc.dg/vect/vect-peel-3.c: Adjust misalignment values
for double-word vectors.
* gcc.dg/vect/vect-peel-4.c: Likewise.
* gcc.dg/vect/bb-slp-10.c: Replace vect_hw_misalign with
vect_element_align.
* gcc.dg/vect/vect.exp: Run no-fast-math-* tests with
-fno-fast-math.
