2022-01-21Strengthen a few OpenACC test casesThomas Schwinge15-57/+202
Rather than rubber-stamp whatever requested vs. actual device kernel launch configuration happens, actually (again) verify the requested values (modulo expected variations). This better highlights that "AMD GCN has an upper limit of 'num_workers(16)'", and the deficiency that "AMD GCN uses the autovectorizer for the vector dimension: the use of a function call in vector-partitioned code [...] is not currently supported". And, this removes several instances of race conditions, where variables are concurrently written to in OpenACC gang-redundant mode. libgomp/ * testsuite/libgomp.oacc-c-c++-common/loop-gwv-1.c: Strengthen. * testsuite/libgomp.oacc-c-c++-common/loop-gwv-2.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-red-gwv-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-red-v-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-red-v-2.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-red-w-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-red-w-2.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-red-wv-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-v-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-w-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-wv-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/routine-gwv-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/routine-v-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/routine-w-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/routine-wv-1.c: Likewise.

2022-01-19libgomp, OpenMP: Fix issue for omp_get_device_num on gcn targets.Marcel Vollweiler1-1/+1
Currently omp_get_device_num does not work on gcn targets with more than one offload device. The reason is that GOMP_DEVICE_NUM_VAR is static in icv-device.c and thus "__gomp_device_num" is not visible in the offload image. This patch removes "static" such that "__gomp_device_num" is now part of the offload image and can now be found in GOMP_OFFLOAD_load_image in the plugin. This is not an issue for nvptx. There, "__gomp_device_num" is in the offload image even with "static". libgomp/ChangeLog: * config/gcn/icv-device.c: Make GOMP_DEVICE_NUM_VAR public (remove "static") to make the device num available in the offload image.

2022-01-13Wait at end of OpenACC asynchronous kernels regionsJulian Brown1-1/+0
In OpenACC 'kernels' decomposition, we're improperly nesting synchronous and asynchronous data and compute regions, giving rise to data races when the asynchronicity is actually executed, as is visible in at least on test case with GCN offloading. The proper fix is to correctly use the asynchronous interfaces, making the currently synchronous data regions fully asynchronous (see also <https://gcc.gnu.org/PR97390> "[OpenACC] 'async' clause on 'data' construct", which is to share the same implementation), but that's for later; for now add some more synchronization. gcc/ * omp-oacc-kernels-decompose.cc (add_wait): New function, split out of...

In the patch that implemented omp_get_device_num(), there was an error where the stringification of GOMP_DEVICE_NUM_VAR, which is the macro expanding to the actual symbol used, was erroneously using the STRINGX() macro in the libgomp offload image symbol search, and expansion of the variable name string through the additional layer of preprocessor symbol was not properly achieved.

2021-12-10amdgcn: Change offload variable table discoveryAndrew Stubbs1-18/+21
Up to now the libgomp GCN plugin has been finding the offload variables by using a symbol lookup, but the AMD runtime requires that the symbols are global for that to work. This was ensured by mkoffload as a post-procssing step, but the LLVM 13 assembler no longer accepts this in the case where the variable was previously declared differently. This patch switches to locating the symbols directly from the offload_var_table, which means that only one symbol needs to be forced global. This changes breaks the libgomp image compatibility so GOMP_VERSION_GCN has also been bumped. gcc/ChangeLog: * config/gcn/mkoffload.c (process_asm): Process the variable table completely differently. (process_obj): Encode the varaible data differently. include/ChangeLog: * gomp-constants.h (GOMP_VERSION_GCN): Bump. libgomp/ChangeLog: * plugin/plugin-gcn.c (struct gcn_image_desc): Remove global_variables. (GOMP_OFFLOAD_load_image): Locate the offload variables via the table, not individual symbols.

2021-12-09OpenMP 5.0: Remove array section base-pointer mapping semantics and other ↵Chung-Lin Tang11-75/+190
front-end adjustments This patch implements three pieces of functionality: (1) Adjust array section mapping to have standards conforming behavior, mapping array sections should *NOT* also map the base-pointer: struct S { int *ptr; ... }; struct S s; Instead of generating this during gimplify: map(to:*_1 [len: 400]) map(attach:s.ptr [bias: 0]) Now, adjust to: (i.e. do not map the base-pointer together. The attach operation is still generated, and if s.ptr is already mapped prior, attachment will happen) The correct way of achieving the base-pointer-also-mapped behavior would be to use: (A small Fortran front-end patch to trans-openmp.c:gfc_trans_omp_array_section is also included, which removes generation of a GOMP_MAP_ALWAYS_POINTER for array types, which appears incorrect and causes a regression in libgomp.fortranlibgomp.fortran/struct-elem-map-1.f90) (2) Related to the first item above, are fixes in libgomp/target.c to not overwrite attached pointers when handling device<->host copies, mainly for the "always" case. (3) The third is a set of changes to the C/C++ front-ends to extend the allowed component access syntax in map clauses. These changes are enabled for both OpenACC and OpenMP. gcc/c/ChangeLog: * c-parser.c (struct omp_dim): New struct type for use inside c_parser_omp_variable_list.

2021-12-02fortran: OpenMP/OpenACC array mapping alignment fix (PR90030)Chung-Lin Tang2-0/+32
Fix issue with the Fortran front-end when mapping arrays: when creating the data MEM_REF for the map clause, there was a convention of casting the referencing pointer to 'c_char *' by fold_convert (build_pointer_type (char_type_node), ptr). This causes the alignment passed to the libgomp runtime for array data hardwared to '1', and causes alignment errors on the offload target. This patch fixes this by removing the char_type_node pointer converts, and adding gcc_asserts to ensure POINTER_TYPE_P (TREE_TYPE (ptr)). PR fortran/90030 gcc/fortran/ChangeLog: * trans-openmp.c (gfc_omp_finish_clause): Remove fold_convert to pointer to char_type_node, add gcc_assert of POINTER_TYPE_P.

2021-11-30Make OpenACC orphan gang reductions errorsCesar Philippidis1-0/+1
This patch promotes all OpenACC gang reductions on orphan loops as errors. Accord to the spec, orphan loops are those which are not lexically nested inside an OpenACC parallel or kernels regions. I.e., acc loops inside acc routines. At first I thought this could be a warning because the gang reduction finalizer uses an atomic update. However, because there is no synchronization between gangs, there is way to guarantee that reduction will have completed once a single gang entity returns from the acc routine call. gcc/c/ * c-typeck.c (c_finish_omp_clauses): Emit an error on orphan OpenACC gang reductions. gcc/cp/ * semantics.c (finish_omp_clauses): Emit an error on orphan OpenACC gang reductions. gcc/fortran/ * openmp.c (oacc_is_parallel, oacc_is_kernels): New 'static' functions.
