------- Comment #56 from lucier at math dot purdue dot edu 2008-01-18 01:38 -------
gcc is now 5-6 times faster than it was nearly two years ago when this was
first reported; many changes have made significant improvements in cpu time.
But Steven Bosscher's patch from December still improved things more on this
test case.
In particular, on 12/20/2007, without the patch, CPU time from
http://gcc.gnu.org/bugzilla/attachment.cgi?id=14799
was
TOTAL : 300.21 19.16 319.52
778432 kB
After Steven Bosscher's patch
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34400#c28
it was
TOTAL : 210.97 15.80 226.88
778432 kB
and today it's
TOTAL : 281.08 18.03 299.41
776514 kB
Would it still be a good idea to apply Steven's patch?
