I tried vect-97.c on power-pc and couldn't reproduce the problem.
I don't know if this means that the problem goes away with recent
patches or that it only occurs when vectorizing on ia64. I don't
have the ability to build and test on ia64.

I don't see this failure anymore on i686-pc-linux-gnu and powerpc-apple-darwin.

When were you seeing it on those platforms? My monitoring has never shown
this as an i686-pc-linux-gnu failure, but it still fails on ia64-hpux,
both -milp32 and -mlp64, as of today's mainline.

you're right, I might have never seen this failure on these platforms.

Appeared between 2005-05-29 13:00 UTC and 2005-05-29 14:30 UTC. I.e., caused by:
Changes by: dorit@gcc.gnu.org 2005-05-29 13:14:43
Modified files:
gcc : ChangeLog tree-flow.h tree-optimize.c
tree-ssa-alias.c tree-vect-transform.c
Log message:
2005-05-29 Keith Besaw <kbesaw@us.ibm.com>
* tree-ssa-alias.c (new_type_alias): New procedure to
create a type memory tag for a pointer with a may-alias
set determined from a variable declaration.
* tree-flow.h: export declaration of new_type_alias
* tree-optimize.c (init_tree_optimization_passes): document
that pass_may_alias cannot be called after pass_vectorize.
* tree-vect-transform (vect_create_data_ref_ptr): Call
new_type_alias when an type memory tag isn't available
for a reference.
(vectorizable_store): Use copy_virtual_operands to update
virtual defs in place (so that loop_version can be called).
Call mark_for_renaming for the virtual defs in case peeling
is done and virtual uses outside the loop need to be updated.
The problem ought to be reproducible with a cross-compiler cc1.

Started passing again on ia64-hpux between 20050708 and 20050711, I don't know
about on the other platforms discussed.

Test vect-97.c currently passes on ia64-linux and passed on alpha-dec-osf5.1b
on 20050805, and the submitter said it passes on ia64-hpux; this PR can
probably be closed.
