6 dayslibgomp: Add Fortran version of acc_copyout_finalize_async and ↵Tobias Burnus1-0/+71
acc_delete_finalize_async OpenACC 2.5 added several functions for C and Fortran; while acc_{copyout,delete}{,_finalize,_async} exist for both, for some reasons only the C version of acc_{copyout,delete}_finalize_async was actually added, even though the documentation (.texi) and the .map file listed also the auxiliar Fortran functions! OpenACC 2.5 added the Fortran version with the following odd interface: 'type, dimension(:[,:]...)'. In OpenACC 2.6, it was then updated to the Fortran 2018 syntax: 'type(*), dimension(..)', which is also used in openacc.f90 internally. This commit now also updates the documentation to the newer syntax - plus fixes a function-name typo: acc_delete_async_finalize should have the _async at the end not in the middle! libgomp/ChangeLog: * libgomp.map (OACC_2.5): Move previously unimplemented acc_{copyout,delete}_finalize_async_{32,64,array}_h_ to ... (OACC_2.6.1): ... here. * libgomp.texi (acc_copyin, acc_present_or_copyin, acc_create, acc_present_or_create, acc_copyout, acc_update_device, acc_update_self, acc_is_present): Use 'type(*), dimension(..)' instead of 'type, dimension(:[,:]...)' for Fortran. (acc_delete): Likewise; change acc_delete_async_finalize to acc_delete_finalize_async. * openacc.f90 (openacc_internal): Add interfaces for acc_{copyout,delete}_finalize_async_{{32,64,array}_h,_l}. (openacc): Add generic interfaces for acc_copyout_finalize_async and acc_delete_finalize_async. (acc_{copyout,delete}_finalize_async_{32,64,array}_h): New. * openacc_lib.h: Add generic interfaces for acc_copyout_finalize_async and acc_delete_finalize_async. * testsuite/libgomp.oacc-fortran/pr92970-1.f90: New test.
2025-06-24Fortran/OpenACC: Add Fortran support for acc_attach/acc_detachTobias Burnus2-0/+87
While C/++ support the routines acc_attach{,_async} and acc_detach{,_finalize}{,_async} routines since a long time, the Fortran API routines where only added in OpenACC 3.3. Unfortunately, they cannot directly be implemented in the library as GCC will introduce a temporary array descriptor in some cases, which causes the attempted attachment to the this temporary variable instead of to the original one. Therefore, those API routines are handled in a special way in the compiler. gcc/fortran/ChangeLog: * trans-stmt.cc (gfc_trans_call_acc_attach_detach): New. (gfc_trans_call): Call it. libgomp/ChangeLog: * libgomp.texi (acc_attach, acc_detach): Update for Fortran version. * openacc.f90 (acc_attach{,_async}, acc_detach{,_finalize}{,_async}): Add. * openacc_lib.h: Likewise. * testsuite/libgomp.oacc-fortran/acc-attach-detach-1.f90: New test. * testsuite/libgomp.oacc-fortran/acc-attach-detach-2.f90: New test.

2022-10-28OpenACC: Don't gang-privatize artificial variables [PR90115]Julian Brown5-37/+22
This patch prevents compiler-generated artificial variables from being treated as privatization candidates for OpenACC. The rationale is that e.g. "gang-private" variables actually must be shared by each worker and vector spawned within a particular gang, but that sharing is not necessary for any compiler-generated variable (at least at present, but no such need is anticipated either). Variables on the stack (and machine registers) are already private per-"thread" (gang, worker and/or vector), and that's fine for artificial variables. We're restricting this to blocks, as we still need to understand what it means for a 'DECL_ARTIFICIAL' to appear in a 'private' clause. Several tests need their scan output patterns adjusted to compensate. 2022-10-14 Julian Brown <julian@codesourcery.com> PR middle-end/90115 gcc/ * omp-low.cc (oacc_privatization_candidate_p): Artificial vars are not privatization candidates. libgomp/ * testsuite/libgomp.oacc-fortran/declare-1.f90: Adjust scan output. * testsuite/libgomp.oacc-fortran/host_data-5.F90: Likewise. * testsuite/libgomp.oacc-fortran/if-1.f90: Likewise. * testsuite/libgomp.oacc-fortran/print-1.f90: Likewise. * testsuite/libgomp.oacc-fortran/privatized-ref-2.f90: Likewise.

So that move_sese_region_to_fn works properly, OpenMP/OpenACC constructs for which that function is invoked need an extra artificial BIND_EXPR around their body so that we move all variables of the bodies. The C/C++ FEs do that both for OpenMP constructs like OMP_PARALLEL, OMP_TASK or OMP_TARGET and for OpenACC constructs that behave similarly to OMP_TARGET, but the Fortran FE only does that for OpenMP constructs. The following patch does that for OpenACC constructs too.

making certain variables addressable [PR100280, PR104892] Currently in OpenACC 'kernels' decomposition, there is special handling of 'GOMP_MAP_FORCE_TOFROM', documented to be done to avoid "internal compiler errors in later passes". For performance reasons, the current repetitive to/from device copying for every region is not ideal, compared to using 'present' clauses, as done for almost all other 'GOMP_MAP_*'. Also, the current special handling (incomplete, evidently) is the reason for the PR104892 misbehavior.

2022-02-01[nvptx] Add some support for .local atomicsTom de Vries2-14/+0
The ptx insn atom doesn't support local memory. In case of doing an atomic operation on local memory, we run into: ... operation not supported on global/shared address space ... This is the cuGetErrorString message for CUDA_ERROR_INVALID_ADDRESS_SPACE. The message is somewhat confusing given that actually the operation is not supported on local address space. Fix this by falling back on a non-atomic version when detecting a frame-related memory operand. This only solves some cases that are detected at compile-time. It does however fix the openacc private-atomic-* test-cases. Tested on x86_64 with nvptx accelerator. gcc/ChangeLog: 2022-01-27 Tom de Vries <tdevries@suse.de> * config/nvptx/nvptx.md (define_insn "atomic_compare_and_swap<mode>_1") (define_insn "atomic_exchange<mode>") (define_insn "atomic_fetch_add<mode>") (define_insn "atomic_fetch_addsf") (define_insn "atomic_fetch_<logic><mode>"): Output non-atomic version if memory operands is frame-relative. gcc/testsuite/ChangeLog: 2022-01-31 Tom de Vries <tdevries@suse.de> * gcc.target/nvptx/stack-atomics-run.c: New test. libgomp/ChangeLog: 2022-01-27 Tom de Vries <tdevries@suse.de> * testsuite/libgomp.oacc-c-c++-common/private-atomic-1.c: Remove PR83812 workaround. * testsuite/libgomp.oacc-fortran/private-atomic-1-vector.f90: Same. * testsuite/libgomp.oacc-fortran/private-atomic-1-worker.f90: Same.
