<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-flang-openmp Author: Krzysztof Parzyszek (kparzysz) <details> <summary>Changes</summary> OpenMP 6.0 added an optional logical parameter to the requirement clauses (except ATOMIC_DEFAULT_MEM_ORDER) to indicate whether the clause should take effect or not. The parameter defaults to true if not specified. The parameter value is a compile-time constant expression, but it may require folding to get the final value. Since name resolution happens before folding, the argument expression needs to be analyzed by hand. The determination of the value needs to happen during name resolution because the requirement directives need to be available through module files (and the module reader doesn't to semantic checks beyond name resolution). --- Patch is 25.45 KiB, truncated to 20.00 KiB below, full version: https://github.com/llvm/llvm-project/pull/163557.diff 11 Files Affected: - (modified) flang/include/flang/Lower/OpenMP/Clauses.h (+1) - (modified) flang/include/flang/Parser/dump-parse-tree.h (+5) - (modified) flang/include/flang/Parser/parse-tree.h (+48-1) - (modified) flang/lib/Lower/OpenMP/Clauses.cpp (+59-9) - (modified) flang/lib/Parser/openmp-parsers.cpp (+10-4) - (modified) flang/lib/Semantics/check-omp-structure.cpp (+32-9) - (modified) flang/lib/Semantics/resolve-directives.cpp (+21-3) - (modified) flang/test/Parser/OpenMP/requires.f90 (+14) - (added) flang/test/Semantics/OpenMP/requires10.f90 (+13) - (modified) llvm/include/llvm/Frontend/OpenMP/ClauseT.h (+34-23) - (modified) llvm/include/llvm/Frontend/OpenMP/OMP.td (+10) ``````````diff diff --git a/flang/include/flang/Lower/OpenMP/Clauses.h b/flang/include/flang/Lower/OpenMP/Clauses.h index 5cd196a7869a2..273e61166fd9d 100644 --- a/flang/include/flang/Lower/OpenMP/Clauses.h +++ b/flang/include/flang/Lower/OpenMP/Clauses.h @@ -282,6 +282,7 @@ using Replayable = tomp::clause::ReplayableT<TypeTy, IdTy, ExprTy>;
