Valentin Clement	4df2a5f782	[flang][openacc] Add check for tile clause restriction ... The tile clause in OpenACC 3.0 imposes some restriction. Element in the tile size list are either * or a constant positive integer expression. If there are n tile sizes in the list, the loop construct must be immediately followed by n tightly-nested loops. This patch implement these restrictions and add some tests. Reviewed By: klausler Differential Revision: https://reviews.llvm.org/D86655	2020-08-27 22:13:46 -04:00
Valentin Clement	05169af5ce	[flang][openacc] Handle optional end directive in combined construct ... OpenACC combined construct can have an optional end directive. This patch handle this case in the parsing/unparsing with a canonicalization step. Unlike OmpEndLoopDirective, this doesn't need a special treatment in the pre-fir tree as there is no clause attached to a AccEndCombinedDirective.
