Zdenek,
the audit trail of this bug seems to indicate that it is fixed
and you applied patches. Can you confirm this an close the bug?

the bugreport actually covers two different bugs. One of them
(failure of gcc.dg/20030324-1.c on Sparc) was in fact a latent bug in
the loop optimizer and this is fixed. The rest is indeed a bug in store
motion, but the patch to fix it
http://gcc.gnu.org/ml/gcc-patches/2003-04/msg00328.html
was not approved yet.

I can't reproduce the problem with gcc version 3.4 20031025 (experimental) but
it may still be latent.

Independent of whether the bug can currently be reproduced, killing off invalid
reg notes is clearly the right thing. I'll approve the patch at
http://gcc.gnu.org/ml/gcc-patches/2003-04/msg00328.html provided that the test
case at http://gcc.gnu.org/ml/gcc-patches/2003-04/msg00529.html is also applied
at the same time (if it hasn't been already).

I may be wrong, but the only thing I have seen so far is the comment
that 'I'll approve the patch...' in bugzilla, which I didn't consider an
approval.

Subject: Re: [3.4 regression] optimizer creates wrong code for loop
Hello,
> Zdenek, do you plan to do anything about this PR?
seems that Jeff Law has already applied the patch some time ago:
2003-09-15 Zdenek Dvorak <rakdver@atrey.karlin.mff.cuni.cz>
Jeff Law <law@redhat.com>
* gcse.c (remove_reachable_equiv_notes): New.
replace_store_insn): Call it. Update antic list.
(store_killed_in_insn): Take REG_EQUAL notes into account.
(build_store_vectors, delete_store): Add parameter to
replace_store_insn call.
which is probably the reason why it does not reproduce any more. I will
close the bug.
