I see that the following test fails if reverse iteration of SmallPtrSet is enabled: /clang/test/SemaCXX/warn-loop-analysis.cpp/ This is because in SemaStmt.cpp we iterate SmallPtrSet and output warnings about the variables not used in the loop. Expected output: /warning: variables 'i', 'j', and 'k' used in loop condition not modified/ Output with reverse iteration: /warning: variables 'k', 'j', and 'i...

...here are only 13 files changed that is much less complicated than previously when it’s combined with -EHa. Major code is surrounding at SehTryStmt and _Finally in CGexception.cpp that is the place to house Windows SEH specific code anyways. The implementation chose to lever Parser/Semantic phase (SemaStmt.cpp, JumpDiagnostics.cpp, scope.h, etc) to identify the right _Try scope for LU dispatching because that is the place “warn_jump_out_of_seh_finally” is diagnosed and reported. I feel this is the most robust approach. Local_unwind is an important feature, broadly used in Windows Kernel for all ar...
