Hi,
The other day I noticed that Andreas Jaeger's SPEC2k
testers for the tree-ssa branch have been testing
with BASE="-O2" and PEAK="-O2 -ftree-ccp" for some
time now. But since tree-ccp has been enabled by
default at -O1 already since February (?), BASE==PEAK.
We would get more interesting results if we choose
different flag settings for BASE and PEAK.
I notified Andreas and he asked what flags he should
use instead. So what would be interesting to compare
for tree-ssa? Something like -O1 vs. -O2, or both -O2
but one with a few RTL optimizers disabled? Or
-fdisable-simple (IMVHO not very useful since Diego
already tests that). Make some suggestions! :-)
Gr.
Steven
