[jsm28 at gcc dot gnu dot org]

The following FAILs have appeared on ia64-hpux (both -milp32 and -mlp64) on
mainline on 20050622.  gcc-testresults shows them also on ia64-linux.

FAIL: gcc.dg/vect/vect-reduc-1char.c (test for excess errors)
FAIL: gcc.dg/vect/vect-reduc-1.c (test for excess errors)

The first is a new test.  The second test has changed in the relevant period.

does this ia64 reduction testcase failure still occur?

I still see these failures in my nightly runs.

The compile failures appear to be gone but I get an execution failure on IA64
HP-UX.  There is a second PR (PR 23188) that looks like a duplicate of this and
I *think* this might be the same bug as PR 23240, a litle-endian/big-endian bug
in the IA64 vectorizor code.
