Bug #: 50670
Summary: GCC testsuite try to execute sse2 code on non-sse2
machines
Classification: Unclassified
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: newsgrp@duradsl.dyndns.org
Created attachment 25447
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25447
testsuite gcc.log
When running gcc testsuite on an athlon-xp machine (which does not support
sse2) it tries to execute pr48377.c compiled with -msse2 switch.
/sources/gcc-4.6.1/gcc-build/gcc/xgcc -B/sources/gcc-4.6.1/gcc-build/gcc/
/sources/gcc-4.6.1/gcc-4.6.1/gcc/testsuite/gcc.dg/vect/pr48377.c -msse2
-ftree-vectorize -fno-vect-cost-model -O2 -fdump-tree-vect-details -lm -o
./pr48377.exe
./pr48377.exe
Illegal instruction (core dumped)
No more core if -msse2 switch is removed
This bug is quite similar to PR36889, but IMHO the PR36889 resolution is not
applicable here.
/sources/gcc-4.6.1/gcc-build/gcc/xgcc -v

What |Removed |Added
----------------------------------------------------------------------------
Status|UNCONFIRMED |RESOLVED
Target Milestone|--- |4.7.0
Resolution|--- |FIXED
--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Fixed on the trunk at the time by r0-108118. Even though the testcase was
backported for GCC 4.6.1, the fix for the testcase was not.
So fixed for GCC 4.7.0.
