------- Comment #1 from spop at gcc dot gnu dot org 2010-03-12 22:57 -------
It looks like 10 is still a too high number for
PARAM_GRAPHITE_MAX_NB_SCOP_PARAMS
Could you try with --param graphite-max-nb-scop-params=5
I think we should improve the parameter detection to improve the compile time
for now.
We could also switch to ISL instead of PPL, but that would be possible only in
gcc4.6.
