Needless to say that if we suceed to make our globals effective, we can burn
away the CSE passes taking about 20% of optimized builds, but we are still
far away of that and no one appears to be walking that direction.
Amusingly %13 of that CSE overhead comes from that stupid bit of
code in cselib I posted a patch for.
Honestly, GCC is littered with stupidities like that. Nobody, and I
mean NOBODY is looking into this. I can say this with some certainly
since it took me 5 minutes to discover a %13 overhead that could be
trivially fixed.
