The general-purpose add() now sometimes adds unexpected loop-variant pointers to the AliasSetTracker, so certain loops would be rejected with -polly-allow-modref-calls. Use addUnknown() instead, which has the old behavior. I'm not completely convinced the resulting behavior is actually correct: ScopDetection::isValidAccess seems to mostly ignore "unknown" instructions in the AliasSetTracker. But it's not any worse than what was happening before. Committing without pre-commit review to unbreak the buildbots; the following tests were failing: test/ScopInfo/mod_ref_access_pointee_arguments.ll test/ScopInfo/mod_ref_read_pointee_arguments.ll test/ScopInfo/multidim_2d_with_modref_call_2.ll llvm-svn: 342010 |
