[PATCH 0/7] openmp: OpenMP 5.1 loop transformation directives

with both nvptx-none and amdgcn-amdhsa offloading. Best regards, Frederik Frederik Harwath (7): openmp: Add Fortran support for "omp unroll" directive openmp: Add C/C++ support for "omp unroll" directive openacc: Rename OMP_CLAUSE_TILE to OMP_CLAUSE_OACC_TILE openmp: A

[PATCH 3/7] openacc: Rename OMP_CLAUSE_TILE to OMP_CLAUSE_OACC_TILE

OMP_CLAUSE_TILE will be used for the OpenMP 5.1 loop transformation construct "omp tile". gcc/ChangeLog: * tree-core.h (enum omp_clause_code): Rename OMP_CLAUSE_TILE. * tree.h (OMP_CLAUSE_TILE_LIST): Rename to ... (OMP_CLAUSE_OACC_TILE_LIST): ... this. (OMP_CLAUSE_

[PATCH 4/7] openmp: Add Fortran support for "omp tile"

This commit implements the Fortran front end support for the "omp tile" directive and the corresponding middle end transformation. gcc/fortran/ChangeLog: * gfortran.h (enum gfc_statement): Add ST_OMP_TILE, ST_OMP_END_TILE. (enum gfc_exec_op): Add EXEC_OMP_TILE. (loop_trans

[PATCH 6/7] openmp: Add Fortran support for loop transformations on inner loops

So far the implementation of the "omp tile" and "omp unroll" directives restricted their use to the outermost loop of a loop-nest. This commit changes the Fortran front end to parse and verify the directives on inner loops. The transformation clauses are extended to carry the information about the

[PATCH 00/40] OpenACC "kernels" Improvements

can discuss some of the changes before they can be considered for inclusion in GCC during the next stage 1. Best regards, Frederik Andrew Stubbs (2): openacc: Add data optimization pass openacc: Add runtime a lias checking for OpenACC kernels Frederik Harwath (20): Fortran: Delineariz

[PATCH 03/40] Kernels loops annotation: Fortran.

From: Sandra Loosemore This patch implements the Fortran support for adding "#pragma acc loop auto" annotations to loops in OpenACC kernels regions. It implements the same -fopenacc-kernels-annotate-loops and -Wopenacc-kernels-annotate-loops options that were previously added (and documented) fo

[PATCH 04/40] Additional Fortran testsuite fixes for kernels loops annotation pass.

[PATCH 06/40] Add a "combined" flag for "acc kernels loop" etc directives.

[PATCH 08/40] Annotate inner loops in "acc kernels loop" directives (Fortran).

From: Sandra Loosemore Normally explicit loop directives in a kernels region inhibit automatic annotation of other loops in the same nest, on the theory that users have indicated they want manual control over that section of code. However there seems to be an expectation in user code that the co

[PATCH 09/40] Permit calls to builtins and intrinsics in kernels loops.

From: Sandra Loosemore This tweak to the OpenACC kernels loop annotation relaxes the restrictions on function calls in the loop body. Normally calls to functions not explicitly marked with a parallelism attribute are not permitted, but C/C++ builtins and Fortran intrinsics have known semantics s

[PATCH 10/40] Fix patterns in Fortran tests for kernels loop annotation.

From: Sandra Loosemore Several of the Fortran tests for kernels loop annotation were failing due to changes in the formatting of "acc loop" constructs in the dump file. Now the "auto" clause appears first, instead of after "private". 2020-08-23 Sandra Loosemore gcc/testsuite/

[PATCH 13/40] Fortran: Delinearize array accesses

The Fortran front end presently linearizes accesses to multi-dimensional arrays by combining the indices for the various dimensions into a series of explicit multiplies and adds with refactoring to allow CSE of invariant parts of the computation. Unfortunately this representation interferes with Gr
