             Bug #: 50988
           Summary: gcc.target/powerpc/altivec-34.c: Test build failure on
                    non-AltiVec targets
    Classification: Unclassified
           Product: gcc
           Version: 4.6.2
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: testsuite
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: Kyle.D.Moffett@boeing.com


All of the other AltiVec tests (except altivec-34.c) have:
  /* { dg-require-effective-target powerpc_altivec_ok } */

As a result, a bogus testcase failure is generated on powerpc-linux-gnuspe:
  FAIL: gcc.target/powerpc/altivec-34.c (test for excess errors)
  Excess errors:
 
/srv/build/kmoffett/gcc-4.6-4.6.2/src/gcc/testsuite/gcc.target/powerpc/altivec-34.c:1:0:
error: AltiVec and E500 instructions cannot coexist

Cheers,
Kyle Moffett

Oops, hit "Submit" before I finished editing...

The fix for the "altivec-34.c" test should be to add this line somwhere at the
top:
  /* { dg-require-effective-target powerpc_altivec_ok } */

Additionally, the "gcc.target/powerpc/ehreturn.c" test is failing on e500 as
r30 is saved using "evstdd 30," instead of "stw 30," or "std 30,".  The
scan-assembler line should be updated to allow the e500 evstdd instruction as
well.

Then the "gcc.target/powerpc/ppc-pow.c" test fails with a bunch of these
errors:
  error: target attribute or pragma changes SPE ABI.

Since the test seems to be assuming power6 and standard PPC floating point, I
assume that it should be disabled on powerpc-linux-gnuspe targets.

Cheers,
Kyle Moffett

Klye, could you check this patch on your SPE compiler before I check it in?

I decided to go ahead, and just commit the changes.  Reopen the bug if it does
not fix it for your system.  Change committed in subversion id 182728.
