[Bug tree-optimization/26854] Inordinate compile times on large routines



------- Comment #23 from lucier at math dot purdue dot edu  2006-12-11 06:27 -------
Subject: Re:  Inordinate compile times on large routines

After Andrew MacLeod's changes here

http://gcc.gnu.org/ml/gcc-patches/2006-12/msg00691.html

I see

tree SSA to normal    :   5.23 ( 1%) usr   0.06 ( 0%) sys   5.30  
( 1%) wall   52594 kB ( 7%) ggc

instead of

tree SSA to normal    :  30.22 ( 7%) usr   0.07 ( 1%) sys  30.74  
( 6%) wall   54480 kB ( 7%) ggc

Very nice.

Other passes with noticeable run times remaining are

tree alias analysis   : 125.17 (28%) usr   0.52 ( 4%) sys 126.90  
(27%) wall   18481 kB ( 3%) ggc
tree FRE              : 207.84 (46%) usr   0.19 ( 1%) sys 208.56  
(45%) wall   23470 kB ( 3%) ggc
