           Summary: simd testsuite regressions due to -msse triggered by --
                    with-arch
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: gschafer at zip dot com dot au
                CC: gcc-bugs at gcc dot gnu dot org
  GCC host triplet: i686-pc-linux-gnu

Building a compiler with "--with-arch=athlon-4" triggers these tests to fail:-

FAIL: gcc.c-torture/compile/simd-5.c (test for excess errors)
FAIL: gcc.c-torture/execute/simd-1.c execution,  -O0 
FAIL: gcc.c-torture/execute/simd-1.c execution,  -O1 
FAIL: gcc.c-torture/execute/simd-1.c execution,  -O2 
FAIL: gcc.c-torture/execute/simd-1.c execution,  -O3 -fomit-frame-pointer 
FAIL: gcc.c-torture/execute/simd-1.c execution,  -O3 -g 
FAIL: gcc.c-torture/execute/simd-1.c execution,  -Os 
FAIL: gcc.c-torture/execute/simd-2.c execution,  -Os 
FAIL: gcc.c-torture/execute/simd-4.c execution,  -O1 
FAIL: gcc.c-torture/execute/simd-4.c execution,  -O2 
FAIL: gcc.c-torture/execute/simd-4.c execution,  -O3 -fomit-frame-pointer 
FAIL: gcc.c-torture/execute/simd-4.c execution,  -O3 -g 
FAIL: gcc.c-torture/execute/simd-4.c execution,  -Os

The test results are here:-

http://gcc.gnu.org/ml/gcc-testresults/2003-08/msg00245.html

The 1st in that list appears to be same as bug 7277 (i.e. triggered by -mmmx) so
pls ignore that one.

All the others seem to be triggered by -msse and may well be an indication of
general problems with the vector types. If this is the case and you already have
a bug report then sorry for wasting your time.

simd-1.c calls abort()
simd-2.c segfaults
simd-4.c calls abort()

Thanks.

------- Additional Comments From pinskia at physics dot uc dot edu  2003-08-05 05:15 -------
All of these are caused by the stack not being aligned, so this is a dup of bug 10395.

*** This bug has been marked as a duplicate of 10395 ***
