2025-01-02OpenMP: Fortran front-end support for dispatch + adjust_argsPaul-Antoine Arras5-0/+316
This patch adds support for the `dispatch` construct and the `adjust_args` clause to the Fortran front-end. Handling of `adjust_args` across translation units is missing due to PR115271. Minor modifications to the C++ FE and the ME are also folded into this patch as a side effect of the Fortran work. gcc/c-family/ChangeLog: * c-attribs.cc: (c_common_gnu_attributes): Rename "omp declare variant variant adjust_args" into "omp declare variant variant args" to also accommodate append_args. gcc/cp/ChangeLog: * parser.cc (cp_parser_omp_dispatch): Handle INDIRECT_REF. gcc/fortran/ChangeLog: * dump-parse-tree.cc (show_omp_clauses): Handle novariants and nocontext clauses.

Follow up to r15-5392-g884637b6362391. As the name implies, GOMP_OFFLOAD_openacc_async_construct is also externally called. Hence, partially revert previous commit to permit unlocking handling in oacc-async.c's lookup_goacc_asyncqueue by not failing fatally. Hence, also the other (indirect) callers had to be updated: GOMP_OFFLOAD_dev2dev fails now with 'false' and GOMP_OFFLOAD_async_run fatally. libgomp/ChangeLog: * plugin/plugin-gcn.c (GOMP_OFFLOAD_dev2dev, GOMP_OFFLOAD_async_run): Handle omp_async_queue == NULL after call to maybe_init_omp_async.

PTX '%dynamic_smem_size' was "Introduced in PTX ISA version 4.1", and "Requires 'sm_20' or higher". Given that GCC/nvptx generally supports 'sm_20', only the PTX ISA version matters here, and that's all fine if just using GCC's defaults.

2024-12-03OpenMP: 'allocate' directive - fixes for 'alignof' and [[omp::decl]]Tobias Burnus2-0/+60
Fixed a check to permit [[omp::decl(allocate,...)]] parsing in C. Additionaly, we discussed that 'allocate align' should not affect 'alignof' to avoid issues like with: int a; _Alignas(_Alignof(a)) int b; #pragma omp allocate(a) align(128) _Alignas(_Alignof(a)) int c; Thus, the alignment is no longer set in the C and Fortran front ends, but for static variables now in varpool_node::finalize_decl. (For stack variables, the alignment is handled in gimplify_bind_expr.) NOTE: 'omp allocate' is not yet supported in C++. gcc/c/ChangeLog: * c-parser.cc (c_parser_omp_allocate): Only check scope if not in_omp_decl_attribute. Remove setting the alignment. gcc/ChangeLog: * cgraphunit.cc (varpool_node::finalize_decl): Set alignment based on OpenMP's 'omp allocate' attribute/directive. gcc/fortran/ChangeLog: * trans-decl.cc (gfc_finish_var_decl): Remove setting the alignment. libgomp/ChangeLog: * libgomp.texi (Memory allocation): Mention (non-)effect of 'align' on _Alignof. * testsuite/libgomp.c/allocate-7.c: New test. gcc/testsuite/ChangeLog: * c-c++-common/gomp/allocate-18.c: Check that alignof is unaffected by 'omp allocate'. * c-c++-common/gomp/allocate-19.c: Likewise.

Almost all device-specific settings are now centralised into gcn-devices.def for the compiler, mkoffload, and libgomp. No longer will we have to touch 10 files in multiple places just to add another device without any exotic features. (New ISAs and devices with incompatible metadata will continue to need a bit more.) In order to remove the device-specific conditionals in the code a new value HSACO_ATTR_UNSUPPORTED has been added, indicating that the assembler will reject any setting of that option.

Kind of undoes r15-4315-g9f549d216c9716 by adding the original testcase back; namely, adding acc_on_device-1-3.f as acc_on_device-1-4.f with -fno-builtin-acc_on_device removed. libgomp/ChangeLog: * testsuite/libgomp.oacc-fortran/acc_on_device-1-4.f: New test; same as acc_on_device-1-3.f but using the builtin function.

2024-10-13Fortran: Use OpenACC's acc_on_device builtin, fix OpenMP' ↵Tobias Burnus7-26/+104
__builtin_is_initial_device It turned out that 'if (omp_is_initial_device() .eqv. true)' gave an ICE due to comparing 'int' with 'logical(4)'. When digging deeper, it also turned out that when the procedure pointer is needed, the builtin cannot be used, either. (Follow up to r15-2799-gf1bfba3a9b3f31 ) Extend the code to also use the builtin acc_on_device with OpenACC, which was previously only used in C/C++. Additionally, fix folding when offloading is not enabled. Fixes additionally the BT_BOOL data type, which was 'char'/integer(1) instead of bool, backing the booleaness; use bool_type_node as the rest of GCC. gcc/fortran/ChangeLog: * gfortran.h (gfc_option_t): Add disable_acc_on_device. * options.cc (gfc_handle_option): Handle -fno-builtin-acc_on_device. * trans-decl.cc (gfc_get_extern_function_decl): Move __builtin_omp_is_initial_device handling to ... * trans-expr.cc (get_builtin_fn): ... this new function. (conv_function_val): Call it. (update_builtin_function): New. (gfc_conv_procedure_call): Call it. * types.def (BT_BOOL): Fix type by using bool_type_node. gcc/ChangeLog: * gimple-fold.cc (gimple_fold_builtin_acc_on_device): Also fold when offloading is not configured. libgomp/ChangeLog: * libgomp.texi (TR13): Fix minor typos. (omp_is_initial_device): Improve wording. (acc_on_device): Note how to disable the builtin. * testsuite/libgomp.oacc-fortran/acc_on_device-1-1.f90: Remove TODO. * testsuite/libgomp.oacc-fortran/acc_on_device-1-2.f: Likewise.
