18 hoursOpenMP: Fix append_args handling in modify_call_for_omp_dispatchTobias Burnus2-0/+537
At tree level, the addr ref is also required for array dummy arguments, contrary to C; the GOMP_interop calls in modify_call_for_omp_dispatch were updated accordingly (using build_fold_addr_expr). As the GOMP_interop calls had no location data associated with them, the init call happened as soon as executing the previous line of code, which was confusing; solution: use the location data of the function call itself.

Note that this commit also updates the API interface to OpenMP 6.0; while 5.1 and 5.2 use 'int *' for the the ret_code argument, OpenMP 6.0 changed this to omp_interop_rc_t *; this enum also exists in OpenMP 5.1. However, C++ does not like this change such that unless NULL is passed (i.e. the argument is ignored), OpenMP 5.x and 6.x are not compatible. Note that GCC's omp.h already follows OpenMP 6.0 and is now in sync with the documentation. libgomp/ChangeLog: * libgomp.texi (OpenMP 5.1): Add @ref to offload-target specifics for 'interop'.

2025-03-21libgomp/plugin: Add initial interop support to nvptx + gcnTobias Burnus4-3/+1342
The interop directive operates on an opaque object that represents a foreign runtime. This commit adds support for this to the two offloading plugins. For nvptx, it supports cuda, cuda_driver and hip; the latter is AMD's version of CUDA which for Nvidia devices boils down to normal CUDA. Thus, at the end for this limited use, cuda/cuda_driver/hip are all the same - and for plugin-nvptx.c, the they differ only in terms of what gets fr_id, fr_name and get_interop_type_desc return. For gcn, it supports hip and hsa. Regarding get-mapped-ptr-1.c: That's actually a fix for the GOMP_interop commit r15-8654-g99e2906ae255fc that added GOMP_DEVICE_DEFAULT_OMP_61 alias omp_default_device, which is a conforming device number.

libgomp.exp added -fno-diagnostics-show-caret and -fdiagnostics-color=never as 'additional_flags' for compilation. However, it turned out that this now is insufficient as the [...] part of diagnostics have a hyperlink URL. Solution: Use the -fdiagnostics-plain-output flag instead, added in commit r11-2701-g129a1319c0ab73. This flag currently implies the following flags: -fno-diagnostics-show-caret -fno-diagnostics-show-line-numbers -fdiagnostics-color=never -fdiagnostics-urls=never -fdiagnostics-path-format=separate-events -fdiagnostics-text-art-charset=none -fno-diagnostics-show-event-links libgomp/ChangeLog: * testsuite/lib/libgomp.exp (libgomp_init): Add -fdiagnostics-plain-output to additional_flags; remove -fno-diagnostics-show-caret and -fdiagnostics-color=never.

2025-01-30OpenMP: append_args clause fixes + Fortran supportTobias Burnus1-7/+8
This fixes a large number of smaller and larger issues with the append_args clause to 'declare variant' and adds Fortran support for it; it also contains a larger number of testcases. In particular, for Fortran, it also handles passing allocatable, pointer, optional arguments to an interop dummy argument with or without value attribute. And it changes the internal representation such that dumping the tree does not lead to an ICE. gcc/c/ChangeLog: * c-parser.cc (c_finish_omp_declare_variant): Modify how append_args is saved internally. gcc/cp/ChangeLog: * parser.cc (cp_finish_omp_declare_variant): Modify how append_args is saved internally. * pt.cc (tsubst_attribute): Likewise. (tsubst_omp_clauses): Remove C_ORT_OMP_DECLARE_SIMD from interop handling as no longer called for it. * decl.cc (omp_declare_variant_finalize_one): Update append_args changes; fixes for ADL input. gcc/fortran/ChangeLog: * gfortran.h (gfc_omp_declare_variant): Add append_args_list. * openmp.cc (gfc_parser_omp_clause_init_modifiers): New; splitt of from ... (gfc_match_omp_init): ... here; call it. (gfc_match_omp_declare_variant): Update to handle append_args clause; some syntax handling fixes. * trans-openmp.cc (gfc_trans_omp_declare_variant): Handle append_args clause; add some diagnostic. gcc/ChangeLog: * gimplify.cc (gimplify_call_expr): For OpenMP's append_args clause processed by 'omp dispatch', update for internal-representation changes; fix handling of hidden arguments, add some comments and handle Fortran's value dummy and optional/pointer/allocatable actual args. libgomp/ChangeLog: * libgomp.texi (Impl.

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.
