[WinEH] Allow for multiple terminatepads Fixes verifier errors with Windows EH and OpenMP, which injects a terminate scope around parallel blocks. Fixes PR35778 llvm-svn: 321676
2018-01-03 05:34:16 +08:00

[OPENMP] Support for -fopenmp-simd option with compilation of simd loops only. Added support for -fopenmp-simd option that allows compilation of simd-based constructs without emission of OpenMP runtime calls. llvm-svn: 321560

[OPENMP] Fix PR35156: Get correct thread id with windows exceptions. If the thread id is requested in windows mode within funclets, we may generate incorrect function call that could lead to broken codegen. llvm-svn: 317208

[OPENMP] Fix PR35152: Do not use getInvokeDest() function for EH checks. The compiler may crash under some conditions if the getInvokeDest() is used, but later it is not used. Fixed this problem in OpenMP. llvm-svn: 317227
