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
Date: Mon, 21 Jul 2008 15:31:00 -0000	[thread overview]
Message-ID: <bug-36889-10678@http.gcc.gnu.org/bugzilla/> (raw)

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
FAIL: gfortran.fortran-torture/execute/common.f90 execution, -O2

-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'
./gcc-4.0.4/stage3-gcc/testsuite/gfortran/gfortran.log:0
./gcc-4.1.2/stage3-gcc/testsuite/gfortran/gfortran.log:0
./gcc-4.2.4/gcc/testsuite/gfortran/gfortran.log:0
./gcc-4.3.1/gcc/testsuite/gfortran/gfortran.log:0
./gcc-4.4-20080718/gcc/testsuite/gfortran/gfortran.log:219
