Hi,

This patch change the vect.exp to run the vect testsuite even the
target has no paired single support.

Tested on ia64 machine:

Running /tools/trunk/gcc/testsuite/gcc.dg/vect/vect.exp ...
FAIL: gcc.dg/vect/pr40254.c execution test

Thanks,
Eric

The code you changed affect mips targets.  How will testing on ia64
help?  Is this a cross compiler?  Additionally, I don't see why the
change is necessary.  You seem to be changing the logic that appends
mpaired-single, not the logic that decides whether to run vect.exp at
all.

Yes. It's a cross compiler for loongson2f. The original logic will
fall into the 'else' fragment when the target doesn't support
paired-single, hence 'return'. The change will make the test go ahead
even the target doesn't support paired-single such as loongson2f which
has SIMD instructions.

Here is the result for the original testsuite.
