------- Comment #7 from dberlin at gcc dot gnu dot org 2005-11-09 22:57 ------- There are also a ton of other bugs related to hard regs in reaching definitions on df.c in mainline, i'm just guessing.
Try the df.c from the dataflow-branch, and see if it fixes the bug, because honestly, i think you are barking up the wrong tree here. Clobbers are most *certainly* not new definitions. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24762
