[Bug rtl-optimization/33928] [4.3/4.4/4.5 Regression] 30% performance slowdown in floating-point code caused by r118475



------- Comment #82 from bonzini at gnu dot org  2009-05-08 09:41 -------
Hm, looking at the time reports the patch will save about 30-40% of the fwprop
execution time, and should fix the memory hog problem, but will still leave in
the 70s needed to compute reaching definitions.  I guess it's a step forward
for -O2 but borderline for -O1.
