Modified:
trunk/osprey/be/com/alias_analyzer.cxx
Log:
Fix bug749:
APO transformation will insert OpenMP pragma in PU.
These pragma is lower after LNO before WOPT, generate a separate PU for the
parallel do body.
These PU has no constraint graph info in IPA output IR file, cause assertion
when trying to read constraint graph summary.
Fix is for OpenMP lower generated pu, directly construct constraint graph for
this PU, don?\194?\146t construct from summary.
