------- Comment #17 from amacleod at redhat dot com 2007-04-05 14:23 ------- Is the output from .optimized different? (once the ssa versions numbers have been stripped). Those PHIs should be irrelevant, the question is whether the different versioning has any effect.
The only way I can think that out-of-ssa could produce different results is if it had to choose between two same-cost coalesces, and the versioning resulted in them being in different places in the coalesce list. Check the .optimized output and if the code is equivalent, the problem is after that stage. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19780
