------- Comment #5 from mmitchel at gcc dot gnu dot org 2005-12-19 18:05 -------
I've marked this as P2. We should try to understand the problem, but inlining
heuristics are notoriously hard to get right, so it's hard to be sure whether
we're seeing a real bug in the compiler, or just a situation where we got lucky
before.

------- Comment #6 from uttamp at us dot ibm dot com 2006-01-17 00:42 -------
With the latest mainline, the performance numbers for parser benchmark are very
close to the reported numbers (on July 29th 2005). With the mainline, parser
numbers on powerpc64-linux with "-O3
-m32 -mcpu=power4 -ffast-math -fpeel-loops -ftree-loop-linear -funroll-loops"
flags is, 197.parser: 438 (and the reported drop was at 423).
Looking at the current numbers I don't think I should investigate this any
further. I'm thinking of closing this bug as FIXED.
Any thoughts?

Reporter says this is fixed, and nobody seems to disagree.
