This series implements support for the "array shape-operator" (OpenMP 5.0, 2.1.4) and strided accesses for update operations. It follows on from the in-review series:
https://gcc.gnu.org/pipermail/gcc-patches/2022-December/609031.html and makes use of some of the infrastructure introduced in those patches. Further comments on individual patches. Tested with offloading to NVPTX. OK (for stage 1)? Thanks, Julian Julian Brown (3): OpenMP: Fix "exit data" for array sections for ref-to-ptr components OpenMP: Allow complete replacement of clause during map/to/from expansion OpenMP: Support strided and shaped-array updates for C++ gcc/c-family/c-common.h | 12 +- gcc/c-family/c-omp.cc | 277 ++++++++--- gcc/c-family/c-pretty-print.cc | 5 + gcc/c/c-parser.cc | 32 +- gcc/c/c-tree.h | 2 +- gcc/c/c-typeck.cc | 58 ++- gcc/cp/cp-objcp-common.cc | 1 + gcc/cp/cp-tree.def | 1 + gcc/cp/cp-tree.h | 13 +- gcc/cp/decl.cc | 75 +++ gcc/cp/decl2.cc | 19 +- gcc/cp/error.cc | 5 + gcc/cp/mangle.cc | 1 + gcc/cp/operators.def | 1 + gcc/cp/parser.cc | 303 ++++++++++- gcc/cp/parser.h | 7 + gcc/cp/pt.cc | 39 +- gcc/cp/semantics.cc | 288 +++++++++-- gcc/cp/typeck.cc | 12 +- gcc/gimplify.cc | 74 ++- gcc/omp-general.cc | 47 ++ gcc/omp-general.h | 4 +- gcc/omp-low.cc | 403 ++++++++++++++- gcc/testsuite/g++.dg/gomp/array-shaping-1.C | 22 + gcc/testsuite/g++.dg/gomp/array-shaping-2.C | 134 +++++ .../g++.dg/gomp/bad-array-shaping-1.C | 47 ++ .../g++.dg/gomp/bad-array-shaping-2.C | 52 ++ .../g++.dg/gomp/bad-array-shaping-3.C | 53 ++ .../g++.dg/gomp/bad-array-shaping-4.C | 60 +++ .../g++.dg/gomp/bad-array-shaping-5.C | 55 ++ .../g++.dg/gomp/bad-array-shaping-6.C | 59 +++ .../g++.dg/gomp/bad-array-shaping-7.C | 48 ++ .../g++.dg/gomp/bad-array-shaping-8.C | 50 ++ gcc/tree-pretty-print.cc | 17 + gcc/tree.def | 2 +- include/gomp-constants.h | 7 +- libgomp/libgomp.h | 14 + libgomp/target.c | 216 +++++--- .../testsuite/libgomp.c++/array-shaping-1.C | 469 ++++++++++++++++++ .../testsuite/libgomp.c++/array-shaping-10.C | 61 +++ .../testsuite/libgomp.c++/array-shaping-11.C | 63 +++ .../testsuite/libgomp.c++/array-shaping-12.C | 65 +++ .../testsuite/libgomp.c++/array-shaping-13.C | 89 ++++ .../testsuite/libgomp.c++/array-shaping-2.C | 38 ++ .../testsuite/libgomp.c++/array-shaping-3.C | 38 ++ .../testsuite/libgomp.c++/array-shaping-4.C | 38 ++ .../testsuite/libgomp.c++/array-shaping-5.C | 38 ++ .../testsuite/libgomp.c++/array-shaping-6.C | 54 ++ .../testsuite/libgomp.c++/array-shaping-7.C | 54 ++ .../testsuite/libgomp.c++/array-shaping-8.C | 65 +++ .../testsuite/libgomp.c++/array-shaping-9.C | 95 ++++ 51 files changed, 3421 insertions(+), 261 deletions(-) create mode 100644 gcc/testsuite/g++.dg/gomp/array-shaping-1.C create mode 100644 gcc/testsuite/g++.dg/gomp/array-shaping-2.C create mode 100644 gcc/testsuite/g++.dg/gomp/bad-array-shaping-1.C create mode 100644 gcc/testsuite/g++.dg/gomp/bad-array-shaping-2.C create mode 100644 gcc/testsuite/g++.dg/gomp/bad-array-shaping-3.C create mode 100644 gcc/testsuite/g++.dg/gomp/bad-array-shaping-4.C create mode 100644 gcc/testsuite/g++.dg/gomp/bad-array-shaping-5.C create mode 100644 gcc/testsuite/g++.dg/gomp/bad-array-shaping-6.C create mode 100644 gcc/testsuite/g++.dg/gomp/bad-array-shaping-7.C create mode 100644 gcc/testsuite/g++.dg/gomp/bad-array-shaping-8.C create mode 100644 libgomp/testsuite/libgomp.c++/array-shaping-1.C create mode 100644 libgomp/testsuite/libgomp.c++/array-shaping-10.C create mode 100644 libgomp/testsuite/libgomp.c++/array-shaping-11.C create mode 100644 libgomp/testsuite/libgomp.c++/array-shaping-12.C create mode 100644 libgomp/testsuite/libgomp.c++/array-shaping-13.C create mode 100644 libgomp/testsuite/libgomp.c++/array-shaping-2.C create mode 100644 libgomp/testsuite/libgomp.c++/array-shaping-3.C create mode 100644 libgomp/testsuite/libgomp.c++/array-shaping-4.C create mode 100644 libgomp/testsuite/libgomp.c++/array-shaping-5.C create mode 100644 libgomp/testsuite/libgomp.c++/array-shaping-6.C create mode 100644 libgomp/testsuite/libgomp.c++/array-shaping-7.C create mode 100644 libgomp/testsuite/libgomp.c++/array-shaping-8.C create mode 100644 libgomp/testsuite/libgomp.c++/array-shaping-9.C -- 2.29.2
