------- 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 ;)
