[Bug tree-optimization/26830] [4.1/4.2 Regression] Insane amount of compile-time / memory needed at -O1 and up

[rguenth at gcc dot gnu dot org]

------- Comment #2 from rguenth at gcc dot gnu dot org  2006-03-23 16:56 -------
gcc 3.3.6 is fine on i686, 400MB ram, 30s compile time at -O1. 3.4.6 is also
fine wit -O1 -funit-at-a-time, so tree-ssa related.  4.0.3 is a little worse,
560MB and 60s, but still reasonable.  So my bet is aliasing - but who knows
until that compile finishes ;)
