[Bug middle-end/41193] [4.5 Regression] slow compilation with graphite / ice with graphite

[spop at gcc dot gnu dot org]

------- Comment #7 from spop at gcc dot gnu dot org  2009-10-15 16:21 -------
With a patch to solve an ICE triggered by this testcase (to be
committed soon with a reduced testcase to the graphite branch),
I am seeing these numbers on the graphite branch:

./f951 -O2 ~/ex/graphite/pr41193.f90

 Graphite loop transforms:   0.46 ( 8%) usr   0.00 ( 0%) sys   0.45 ( 7%) wall 
   412 kB ( 2%) ggc
 Graphite code generation:   0.00 ( 0%) usr   0.00 ( 0%) sys   0.02 ( 0%) wall 
    91 kB ( 0%) ggc

./f951 -O3 ~/ex/graphite/pr41193.f90

 Graphite loop transforms:   0.49 ( 6%) usr   0.00 ( 0%) sys   0.53 ( 6%) wall 
   417 kB ( 1%) ggc
 Graphite code generation:   0.03 ( 0%) usr   0.01 ( 8%) sys   0.05 ( 1%) wall 
    92 kB ( 0%) ggc

./f951 -Os ~/ex/graphite/pr41193.f90

 Graphite loop transforms:   0.35 ( 6%) usr   0.00 ( 0%) sys   0.34 ( 6%) wall 
   317 kB ( 1%) ggc
 Graphite code generation:   0.03 ( 1%) usr   0.00 ( 0%) sys   0.00 ( 0%) wall 
    89 kB ( 0%) ggc
