------- Comment #9 from steven at gcc dot gnu dot org 2005-10-17 09:27 -------
Comments #4 and #5 suggest that there is still some slowdown compared to
gcc 3.4 and earlier, but we know what the problems are and we have open
bug reports for those problems.
Since this bug is now inactive for many months, and there really is not
much information in this bug that isn't reported elsewhere, I'm going to
close this one. After looking at the code differences between 3.4 and 4.1,
I suspect PR18048 is the main source of trouble for the remaining slowdown
so I'm closing this one as a dup of PR18048.
*** This bug has been marked as a duplicate of 18048 ***
