[Bug testsuite/36889] New: [4.4 regression] gfortran.fortran-torture/execute/execute.exp tries to run sse2 execute tests without checking for host support

[brian at dessent dot net]

Apparently something in the recent reorganization of the computation of fortran
torture options has caused -msse2 execute tests to be run without checking if
the host supports sse2:

$ egrep '^flags' /proc/cpuinfo
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov
pat pse36 mmx fxsr sse syscall mp mmxext 3dnowext 3dnow

$ egrep 'FAIL.*execute.*sse2'
build/gcc-4.4-20080718/gcc/testsuite/gfortran/gfortran.sum

-ftree-vectorize -msse2 
FAIL: gfortran.fortran-torture/execute/where_8.f90 execution, -O2
-ftree-vectorize -msse2 

Note that these are the only ones that happen to fail, but all the execute
tests are built and run with the problematic option; this is a regression in
4.4:

$ find . -name gfortran.log | xargs egrep -Hc 'execution.*msse2'

I don't that many folks who don't have a SSE2 compatible machine any more ...

(added testsuite maintainer on CC)

Well now you know one.  I understand that this may not affect most gcc
developers.  However it does affect casual volunteers who run the testsuite. 
By polluting the results with spurious fails it makes the results less useful,
and this sends the general message that volunteers running the testsuite on
old/spare hardware is not welcome.  I don't think that is a message you want to
be sending at all and indeed I seriously doubt that there was any such intent
with the changes.  Rather, I think there is simply an undetected bug that was
not caught exactly because most developers have newish machines.

 tests without checking for host support

The patch works for me, thanks.  (Although I could only test the sse2
part not the ultrasparc part.)
