2022-07-04OpenMP: Move omp requires checks to libgompTobias Burnus1-3/+5
Handle reverse_offload, unified_address, and unified_shared_memory requirements in libgomp by saving them alongside the offload table. When the device lto1 runs, it extracts the data for mkoffload. The latter than passes the value on to GOMP_offload_register_ver. lto1 (either the host one, with -flto [+ ENABLE_OFFLOADING], or in the offload-device lto1) also does the the consistency check is done, erroring out when the 'omp requires' clause use is inconsistent. For all in-principle supported devices, if a requirement cannot be fulfilled, the device is excluded from the (supported) devices list. Currently, none of those requirements are marked as supported for any of the non-host devices. gcc/c/ChangeLog: * c-parser.cc (c_parser_omp_target_data, c_parser_omp_target_update, c_parser_omp_target_enter_data, c_parser_omp_target_exit_data): Set OMP_REQUIRES_TARGET_USED.

2022-07-01OpenMP: Handle tofrom with target enter/exit dataTobias Burnus1-1/+1
In 5.2, a map clause can be map-entering or map-exiting, either containing 'tofrom'.

(OpenMP defaults to 'tofrom'.) gcc/c/ChangeLog: * c-parser.cc (c_parser_omp_target_enter_data, c_parser_omp_target_exit_data): Accept tofrom map-type modifier but use 'to' / 'from' internally. gcc/cp/ChangeLog: * parser.cc (cp_parser_omp_target_enter_data, cp_parser_omp_target_exit_data): Accept tofrom map-type modifier but use 'to' / 'from' internally. gcc/fortran/ChangeLog: * dump-parse-tree.cc (show_omp_namelist): For the map-type, also handle the always modifer and release/delete. * openmp.cc (resolve_omp_clauses): Accept tofrom map-type modifier for target enter/exit data, but use 'to' / 'from' internally. libgomp/ChangeLog: * libgomp.texi (OpenMP 5.2): Mark target enter/exit data with fromto as implemented. gcc/testsuite/ChangeLog: * c-c++-common/gomp/target-data-2.c: New test. * c-c++-common/gomp/target-data-3.c: New test. * gfortran.dg/gomp/target-data-1.f90: New test. * gfortran.dg/gomp/target-data-2.f90: New test.

2022-06-13openmp: Conforming device numbers and omp_{initial,invalid}_deviceJakub Jelinek1-1/+1
OpenMP 5.2 changed once more what device numbers are allowed. In 5.1, valid device numbers were [0, omp_get_num_devices()]. 5.2 makes also -1 valid (calls it omp_initial_device), which is equivalent in behavior to omp_get_num_devices() number but has the advantage that it is a constant. And it also introduces omp_invalid_device which is also a constant with implementation defined value < -1. That value should act like sNaN, any time any device construct (GOMP_target*) or OpenMP runtime API routine is asked for such a device, the program is terminated. And if OMP_TARGET_OFFLOAD=mandatory, all non-conforming device numbers (which is all but [-1, omp_get_num_devices()] other than omp_invalid_device) must be treated like omp_invalid_device. For device constructs, we have a compatibility problem, we've historically used 2 magic negative values to mean something special. GOMP_DEVICE_ICV (-1) means device clause wasn't present, pick the omp_get_default_device () number GOMP_DEVICE_FALLBACK (-2) means the host device (this is used e.g. for #pragma omp target if (cond) where if cond is false, we pass -2 But 5.2 requires that omp_initial_device is -1 (there were discussions about it, advantage of -1 is that one can say iterate over the [-1, omp_get_num_devices()-1] range to get all devices starting with the host/initial one. And also, if user passes -2, unless it is omp_invalid_device, we need to treat it like non-conforming with OMP_TARGET_OFFLOAD=mandatory. So, the patch does on the compiler side some number remapping, user_device_num >= -2U ? user_device_num - 1 : user_device_num. This remapping is done at compile time if device clause has constant argument, otherwise at runtime, and means that for user -1 (omp_initial_device) we pass -2 to GOMP_* in the runtime library where it treats it like host fallback, while -2 is remapped to -3 (one of the non-conforming device numbers, for those it doesn't matter which one is which). omp_invalid_device is then -4. For the OpenMP device runtime APIs, no remapping is done. This patch doesn't deal with the initial default-device-var for OMP_TARGET_OFFLOAD=mandatory , the spec says that the inital ICV value for that should in that case depend on whether there are any offloading devices or not (if not, should be omp_invalid_device), but that means we can't determine the number of devices lazily (and let libraries have the possibility to register their offloading data etc.). 2022-06-13 Jakub Jelinek <jakub@redhat.com> gcc/ * omp-expand.cc (expand_omp_target): Remap user provided device clause arguments, -1 to -2 and -2 to -3, either at compile time if constant, or at runtime. include/ * gomp-constants.h (GOMP_DEVICE_INVALID): Define. libgomp/ * omp.h.in (omp_initial_device, omp_invalid_device): New enumerators. * omp_lib.f90.in (omp_initial_device, omp_invalid_device): New parameters. * omp_lib.h.in (omp_initial_device, omp_invalid_device): Likewise. * target.c (resolve_device): Add remapped argument, handle GOMP_DEVICE_ICV only if remapped is true (and clear remapped), for negative values, treat GOMP_DEVICE_FALLBACK as fallback only if remapped, otherwise treat omp_initial_device that way.

(GOMP_target, GOMP_target_ext, GOMP_target_data, GOMP_target_data_ext, GOMP_target_update, GOMP_target_update_ext, GOMP_target_enter_exit_data): Pass true as remapped argument to resolve_device.

2022-05-20libgomp: Add new runtime routines omp_target_memcpy_async and ↵Marcel Vollweiler1-1/+1
omp_target_memcpy_rect_async This patch adds two new OpenMP runtime routines: omp_target_memcpy_async and omp_target_memcpy_rect_async. Both functions are introduced in OpenMP 5.1 as asynchronous variants of omp_target_memcpy and omp_target_memcpy_rect. In contrast to the synchronous variants, the asynchronous functions have two additional function parameters to allow the specification of task dependences: int depobj_count omp_depend_t *depobj_list integer(c_int), value :: depobj_count integer(omp_depend_kind), optional :: depobj_list(*) The implementation splits the synchronous functions into two parts: (a) check and (b) copy. Then (a) is used in the asynchronous functions for the sequential part, and the actual copy process (b) is executed in a new created task. The sequential part (a) takes into account the requirements for the return values: "The routine returns zero if successful. Otherwise, it returns a non-zero value." (omp_target_memcpy_async, OpenMP 5.1 spec, section 3.8.7) "An application can determine the number of inclusive dimensions supported by an implementation by passing NULL pointers (or C_NULL_PTR, for Fortran) for both dst and src. The routine returns the number of dimensions supported by the implementation for the specified device numbers. No copy operation is performed." (omp_target_memcpy_rect_async, OpenMP 5.1 spec, section 3.8.8) Due to asynchronicity an error is thrown if the asynchronous memcpy is not successful (in contrast to the synchronous functions which use a return value unequal to zero). gcc/ChangeLog: * omp-low.cc (omp_runtime_api_call): Added target_memcpy_async and target_memcpy_rect_async to omp_runtime_apis array. libgomp/ChangeLog: * libgomp.map: Added omp_target_memcpy_async and omp_target_memcpy_rect_async. * libgomp.texi: Both functions are now supported. * omp.h.in: Added omp_target_memcpy_async and omp_target_memcpy_rect_async. * omp_lib.f90.in: Added interfaces for both new functions. * omp_lib.h.in: Likewise. * target.c (ialias_redirect): Added for GOMP_task.

For the namespace/file scope variables it instead behaves as default(none). 2021-09-18 Jakub Jelinek <jakub@redhat.com> gcc/ * gimplify.c (omp_default_clause): For C/C++ default({,first}private), if file/namespace scope variable doesn't have predetermined sharing, treat it as if there was default(none). gcc/c/ * c-parser.c (c_parser_omp_clause_default): Handle private and firstprivate arguments, adjust diagnostics on unknown argument. gcc/cp/ * parser.c (cp_parser_omp_clause_default): Handle private and firstprivate arguments, adjust diagnostics on unknown argument. * cp-gimplify.c (cxx_omp_finish_clause): Handle OMP_CLAUSE_PRIVATE. gcc/testsuite/ * c-c++-common/gomp/default-2.c: New test. * c-c++-common/gomp/default-3.c: New test. * g++.dg/gomp/default-1.C: New test. libgomp/ * testsuite/libgomp.c++/default-1.C: New test. * testsuite/libgomp.c-c++-common/default-1.c: New test. * libgomp.texi (OpenMP 5.1): Mark "private and firstprivate argument to default clause in C and C++" as implemented.

2021-08-12OpenMP 5.1: Add proc-bind 'primary' supportTobias Burnus1-15/+17
In OpenMP 5.1 "master thread" was changed to "primary thread" and the proc_bind clause and the OMP_PROC_BIND environment variable now take 'primary' as argument as alias for 'master', while the latter is deprecated. This commit accepts 'primary' and adds the named constant omp_proc_bind_primary and changes 'master thread' in the documentation; however, given that not even OpenMP 5.0 is fully supported, omp_display_env and the dumps currently still output 'master' and there is no deprecation warning when using the 'master' in the proc_bind clause. gcc/c/ChangeLog: * c-parser.c (c_parser_omp_clause_proc_bind): Accept 'primary' as alias for 'master'. gcc/cp/ChangeLog: * parser.c (cp_parser_omp_clause_proc_bind): Accept 'primary' as alias for 'master'. gcc/fortran/ChangeLog: * gfortran.h (gfc_omp_proc_bind_kind): Add OMP_PROC_BIND_PRIMARY. * dump-parse-tree.c (show_omp_clauses): Add TODO comment to change 'master' to 'primary' in proc_bind for OpenMP 5.1. * intrinsic.texi (OMP_LIB): Mention OpenMP 5.1; add omp_proc_bind_primary. * openmp.c (gfc_match_omp_clauses): Accept 'primary' as alias for 'master'. * trans-openmp.c (gfc_trans_omp_clauses): Handle OMP_PROC_BIND_PRIMARY. gcc/ChangeLog: * tree-core.h (omp_clause_proc_bind_kind): Add OMP_CLAUSE_PROC_BIND_PRIMARY. * tree-pretty-print.c (dump_omp_clause): Add TODO comment to change 'master' to 'primary' in proc_bind for OpenMP 5.1. libgomp/ChangeLog: * env.c (parse_bind_var): Accept 'primary' as alias for 'master'.

2021-08-05openmp: Implement omp_get_device_num routineChung-Lin Tang1-0/+29
This patch implements the omp_get_device_num library routine, specified in OpenMP 5.0. GOMP_DEVICE_NUM_VAR is a macro symbol which defines name of a "device number" variable, is defined on the device-side libgomp, has it's address returned to host-side libgomp during device initialization, and the host libgomp then sets its value to the designated device number. libgomp/ChangeLog: * icv-device.c (omp_get_device_num): New API function, host side. * fortran.c (omp_get_device_num_): New interface function. * libgomp-plugin.h (GOMP_DEVICE_NUM_VAR): Define macro symbol. * libgomp.map (OMP_5.0.2): New version space with omp_get_device_num, omp_get_device_num_. * libgomp.texi (omp_get_device_num): Add documentation for new API function. * omp.h.in (omp_get_device_num): Add declaration. * omp_lib.f90.in (omp_get_device_num): Likewise. * omp_lib.h.in (omp_get_device_num): Likewise. * target.c (gomp_load_image_to_device): If additional entry for device number exists at end of returned entries from 'load_image_func' hook, copy the assigned device number over to the device variable. * config/gcn/icv-device.c (GOMP_DEVICE_NUM_VAR): Define static global.

2020-10-22openmp: Change omp_get_initial_device () to match OpenMP 5.1 requirementsJakub Jelinek1-0/+28
> Therefore, I think until omp_get_initial_device () value is changed, we The following so far untested patch implements that change. OpenMP 4.5 said for omp_get_initial_device: The value of the device number is implementation defined. If it is between 0 and one less than omp_get_num_devices() then it is valid for use with all device constructs and routines; if it is outside that range, then it is only valid for use with the device memory routines and not in the device clause. and OpenMP 5.0 similarly, but OpenMP 5.1 says: The value of the device number is the value returned by the omp_get_num_devices routine. As the new value is compatible with what has been required earlier, I think we can change it already now. 2020-10-22 Jakub Jelinek <jakub@redhat.com> * icv.c (omp_get_initial_device): Remove including corresponding ialias. * icv-device.c (omp_get_initial_device): New function.
