Would gatekeeper help review this patch? https://bugs.open64.net/show_bug.cgi?id=769 Nystrom alias issue: OMPM2001 assert "the child mp pu pool is not equal to _memPool"
This assert happens because, in AliasAnalyzer::~AliasAnalyzer, assume lower_mp will always copy parent PU's aliasTagMap to child in Transfer_Maps. This is correct for APO because lower_mp happens after LNO, then alias analyzer is already there. for openmp testcase, lower_mp is invoked before LNO and preopt in Backend_Processing, so the child PU doesn't have aliasTagmap copied from parent PU. previous fix for APO is not good, it copies extra map and delete directly. Now the fix is always not copy alias tag map when lower_mp create parallel PU. 1. In lower_mp, Create_MicroTask, mark don't copy alias tag map if aliasanalyzer exist. 2. In AliasAnalyzer::~AliasAnalyzer, remove code for deleteing child PU's aliastagmap. Regards Shi Hui
