--- Comment #5 from Pat Haugen <pthaugen at gcc dot gnu.org> --- Well, it looks to be an interaction amongst 3 files from the benchmark. All 3 have to be compiled with r203979 compiler for the benchmark to fail (others are compiled with r203978). I captured assembler output from both revisions of the files and compared, all 3 have differences in code gen. Some are reassociation type diffs (i.e. swapped operands), the others look like the result of RA/scheduling differences. If you truly meant that "no" code gen differences should be present I could attatch any/all of the 3 files. Or if there is a specific dump/info I should look at and/or attach please let me know.
