           Summary: ICE in gcc.dg/altivec-5.c in 3.3 branch for non-Altivec
                    powerpc
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: target
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: dank at kegel dot com
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-unknown-linux-gnu
  GCC host triplet: i686-unknown-linux-gnu
GCC target triplet: powerpc-unknown-linux-gnu

I built and tested gcc-ss-3_3-20030714 using http://kegel.com/crosstool
for two powerpc CPUs that lack altivec support, ppc405 and ppc750.
They both had the following failure in 'make check-gcc':

FAIL: gcc.dg/altivec-5.c (test for excess errors)
Excess errors:

internal compiler error: in extract_insn, at recog.c:2175


Seems like there are two problems here:
1. the compiler shouldn't ICE
2. the test case should't be compiled for targets that don't have altivec
in the triplet (or was that done on purpose?)
