For datem.f from sixtrack, i get
loop invariant motion : 23.03 (17%) usr 0.05 ( 7%) sys 23.82 (16%) wall
loop iv optimization : 21.03 (15%) usr 0.05 (7%) sys 22.13 (16%) walll
On struct-aliasing, which has vuse bypassing enabled (and thus enables more
optimization), the situation is worse:
loop invariant motion : 23.13 (17%) usr 0.04 (6%) sys 23.94 (15%) wall
tree iv optimization : 68.67 (49%) usr 0.29 (40%) sys 74.50 (50%) wall
For maincr.f, we have:
tree iv optimization : 9.72 (23%) usr 0.06 (13%) sys 10.10 (23%) wall

I cannot reproduce the ivopts problem on daten.f (ivopts are <2% for me, which
is not great, but also not so terrible). IM problem reproduces.
mainrc.f currently runs out of memory for me.

Actually mainrc.f does not run out of memory, but causes segfault during garbage
collection (infinite recursion).

the ivopts stuff may have been fixed by your ivopts patch for important candidates.
i'll try maincr again.

IM problem seems to be caused by some inefficiency in store motion (I suspect
scanning loop repeatedly for various insignificant virtual operands). Anyway,
the patch for PR 17133 (complete rewrite of store motion) fixes this (reduces
the compile time to <1%).

Hmm, I found another testcase where we are slow at LIM:
loop invariant motion : 2.55 ( 5%) usr 0.40 ( 3%) sys 3.36 ( 4%) wall
This is PR8361.
Zdenek can you update your patch for the changes where V_MUST_DEF changes and see what the
compile time improvements you get with the patch?

there is an updated version of the patch
http://gcc.gnu.org/ml/gcc-patches/2004-10/msg01642.html
that should work (possibly with minor changes due to some renaming).

Any news here? This is one of the more serious compile time problems
in GCC4, I've seen a number of cases where these passes are high up in
the profile.

As for ivopts, the problems reported under this PR are solved. So if
you have a testcase where ivopts eat more than 1% of time without a good
reason, please let me know.
I will try to update and resend the patch for inefficiency in store
motion.
