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

Subject: [Bug testsuite/36889] New: [4.4 regression] gfortran.fortran-torture/execute/execute.exp tries to run sse2 execute tests without checking for host support
Reply-to: gcc-bugzilla at gcc dot gnu dot org

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'

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'
