[Bug target/26290] [4.1 Regression]: some loop optimizations no longer run at -O2

------- Comment #5 from steven at gcc dot gnu dot org  2006-02-18 14:32 -------
For the record, AMD64  (usr-)timings:

GCC 4.0         GCC 4.1
0m5.412s        0m4.400s
0m5.388s        0m4.404s
0m5.408s        0m4.404s

So for AMD64 we in fact booked significant progress in GCC 4.1 wrt. GCC 4.0.

This is with:
xgcc (GCC) 4.0.3 20060211 (prerelease)
xgcc (GCC) 4.1.0 20060211 (prerelease)
