------- Comment #5 from dominiq at lps dot ens dot fr 2007-11-12 22:23 -------
The regression was caused by revision 130043:
PR rtl-optimization/34012
* fwprop.c (try_fwprop_subst): Do not replace if the new
SET_SRC has a higher cost than the old one.
* gcc.target/i386/pr34012.c: New test.
If I revert it, the failures disappear.
