2022-09-15[OpenMP] Codegen aggregate for outlined function capturesGiorgis Georgakoudis
Parallel regions are outlined as functions with capture variables explicitly generated as distinct parameters in the function's argument list. That complicates the fork_call interface in the OpenMP runtime: (1) the fork_call is variadic since there is a variable number of arguments to forward to the outlined function, (2) wrapping/unwrapping arguments happens in the OpenMP runtime, which is sub-optimal, has been a source of ABI bugs, and has a hardcoded limit (16) in the number of arguments, (3) forwarded arguments must cast to pointer types, which complicates debugging. This patch avoids those issues by aggregating captured arguments in a struct to pass to the fork_call. Reviewed By: jdoerfert, jhuber6, ABataev Differential Revision: https://reviews.llvm.org/D102107
2022-04-07[OpaquePtrs][Clang] Add -no-opaque-pointers to tests (NFC)Nikita Popov
This adds -no-opaque-pointers to clang tests whose output will change when opaque pointers are enabled by default. This is intended to be part of the migration approach described in https://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9. The patch has been produced by replacing %clang_cc1 with %clang_cc1 -no-opaque-pointers for tests that fail with opaque pointers enabled. Worth noting that this doesn't cover all tests, there's a remaining ~40 tests not using %clang_cc1 that will need a followup change. Differential Revision: https://reviews.llvm.org/D123115

2021-09-18OpenMP 5.0 metadirectivealokmishra.besu
This patch supports OpenMP 5.0 metadirective features. It is implemented keeping the OpenMP 5.1 features like dynamic user condition in mind. A new function, getBestWhenMatchForContext, is defined in llvm/Frontend/OpenMP/OMPContext.h Currently this function return the index of the when clause with the highest score from the ones applicable in the Context. But this function is declared with an array which can be used in OpenMP 5.1 implementation to select all the valid when clauses which can be resolved in runtime. Currently this array is set to null by default and its implementation is left for future. Reviewed By: jdoerfert Differential Revision: https://reviews.llvm.org/D91944
