Subject: [Bug optimization/14637] [lno] wrong code with -O2 -finline-functions
Date: Fri, 19 Mar 2004 21:04:00 -0000	[thread overview]

------- Additional Comments From reichelt at gcc dot gnu dot org  2004-03-19 21:03 -------
This might be related to PR 14433.
When I did a full bootstrap, the bug was there.
When I compiled tree-ssa by hand it disappeared.
To me this looks like a miscompilation of the compiler.

Fortunately, the bug disappeared on 2004-03-12.
I don't know when it appeared (since doing a full bootstrap
for each iteration of a binary search was just too much work).

Since the last merge of the lno-branch was before that date,
it might be possible that you ran into the same problem on
the lno-branch.

To support that theory you might want to try tree-ssa as of
2004-03-10 and see whether you can reproduce the problem there.
Or you can wait for the next lno-merge, and see whether the bug
disappears or not.
