2025-03-21OpenMP: 'interop' construct - add ME support + target-independent libgompPaul-Antoine Arras1-1/+12
This patch partially enables use of the OpenMP interop construct by adding middle end support, mostly in the omplower pass, and in the target-independent part of the libgomp runtime. It follows up on previous patches for C, C++ and Fortran front ends support. The full interop feature requires another patch to enable foreign runtime support in libgomp plugins. gcc/ChangeLog: * builtin-types.def (BT_FN_VOID_INT_INT_PTR_PTR_PTR_INT_PTR_INT_PTR_UINT_PTR): New. * gimple-low.cc (lower_stmt): Handle GIMPLE_OMP_INTEROP. * gimple-pretty-print.cc (dump_gimple_omp_interop): New function.

2025-02-11Synchronize include/dwarf2.def with binutilsRoger Sayle1-0/+2
The contents of include/dwarf2.def have diverged between the gcc and the binutils repositories. Currently, it's impossible to build a combined tree, as GCC won't build with the binutils version of dwarf2.def and binutils won't build with the gcc version. This patch realigns this file by copying the defintion of DW_CFA_AARCH64_negate_ra_state_with_pc from binutils, restoring the ability to build a combined source tree. 2025-02-11 Roger Sayle <roger@nextmovesoftware.com> include/ChangeLog * dwarf2.def (DW_CFA_AARCH64_negate_ra_state_with_pc): Define.

2025-01-08dwarf2out: Emit DWARF 6 DW_AT_language_{name,version}Jakub Jelinek2-1/+57
DWARF has voted in recently https://dwarfstd.org/issues/241209.1.html , which is basically just a guarantee that the DWARF 6 draft DW_AT_language_{name,version} attribute codes and content of https://dwarfstd.org/languages-v6.html can be used as an extension in DWARF 5 and won't be changed. So, this patch is an alternative to the https://gcc.gnu.org/pipermail/gcc-patches/2024-November/669671.html patch, which had the major problem that it required changing all the DWARF consumers to be able to debug C17 or later or C++17 or later sources. This patch uses still DWARF 5 DW_LANG_C11 or DW_LANG_C_plus_plus_14, the latest code in DWARF 5 proper, so all DWARF 5 capable consumers should be able to deal with that, but additionally emits the DWARF 6 attributes so that newer DWARF consumers can see it isn't just C++14 but say C++23 or C11 but C23. Consumers which don't know those DWARF 6 attributes would just ignore them. This is like any other -gno-strict-dwarf extension, except that normally we emit say DWARF 5 codes where possible only after DWARF 5 is released, while in this case there is a guarantee it can be used before DWARF 6 is released. 2025-01-08 Jakub Jelinek <jakub@redhat.com> include/ * dwarf2.h (enum dwarf_source_language): Fix comment pasto.

2024-11-22OpenMP: 'interop' construct - add C/C++ parser support, improve Fortran parsingTobias Burnus1-3/+4
Add middle end support for the 'interop' directive and the 'init', 'use', and 'destroy' clauses - but fail with a sorry, unimplemented in gimplify.cc. For Fortran, generate the tree code, update the internal representation, add some more diagnostic checks and update for newer specification changes ('fr' only takes a single value, but it integer expressions are permitted again [like with the old syntax] not only constant identifiers). For C and C++, this patch adds the full parser support for 'interop'. Still missing is actually handling the directive in the middle end and in libgomp. The GOMP_INTEROP_IFR_* internal values have been changed to have space for vendor specific values that are adjacent to the existing values but negative, if needed. gcc/c-family/ChangeLog: * c-common.h (enum c_omp_region_type): Add C_ORT_INTEROP and C_ORT_OMP_INTEROP.

2024-11-21include: Add new post-DWARF 5 DW_LANG_* enumeratorsJakub Jelinek1-0/+20
DWARF changed the language code assignment to be on a web page and after DWARF 5 has been published already 27 codes have been assigned. We have some of those already in the header, but most of them were missing, including one added just yesterday (DW_LANG_C23). Note, this is really post-DWARF 5 stuff rather than DWARF 6, because DWARF 6 plans to switch from DW_AT_language to DW_AT_language_{name,version} pair where we'll say DW_LNAME_C with 202311 version instead of this. 2024-11-21 Jakub Jelinek <jakub@redhat.com> * dwarf2.h (enum dwarf_source_language): Add comment where the post DWARF 5 additions start.

2024-10-25non-gcc: Remove trailing whitespaceJakub Jelinek15-37/+37
I've tried to build stage3 with -Wleading-whitespace=blanks -Wtrailing-whitespace=blank -Wno-error=leading-whitespace=blanks -Wno-error=trailing-whitespace=blank added to STRICT_WARN and that expectably resulted in about 2744 unique trailing whitespace warnings and 124837 leading whitespace warnings when excluding *.md files (which obviously is in big part a generator issue). Others from that are generator related, I think those need to be solved later. The following patch just fixes up the easy case (trailing whitespace), which could be easily automated: for i in `find . -name \*.h -o -name \*.cc -o -name \*.c | xargs grep -l '[ ]$' | grep -v testsuite/`; do sed -i -e 's/[ ]*$//' $i; done I've excluded files which I knew are obviously generated or go FE. Is there anything else we'd want to avoid the changes? Due to patch size, I've split it between gcc/ part and rest (include/, libiberty/, libgcc/, libcpp/, libstdc++-v3/; this part). 2024-10-24 Jakub Jelinek <jakub@redhat.com> include/ * dyn-string.h:

2024-10-07OpenMP: Allocate directive for static vars, clean upTobias Burnus1-0/+8
For the 'allocate' directive, remove the sorry for static variables and just keep using normal memory, but honor the requested alignment and set a DECL_ATTRIBUTE in case a target may want to make use of this later on. The documentation is updated accordingly. The C diagnostic to check for predefined allocators (req. for static vars) failed to accept GCC's ompx_gnu_... allocator, now fixed. (Fortran was already okay; but both now use new common #defined value for checking.) And while Fortran common block variables are still rejected, the check has been improved as before the sorry diagnostic did not work for common blocks in modules. Finally, for 'allocate' clause on the target/task/taskloop directives, there is now a warning for omp_thread_mem_alloc (i.e. predefined allocator with access = thread), which is undefined behavior according to the OpenMP specification. And, last, testing showed that var decl + static_assert sets TREE_USED but does not produce a statement list in C, which did run into an assert in gimplify. This special case is now also handled. gcc/c/ChangeLog: * c-parser.cc (c_parser_omp_allocate): Set alignment for alignof; accept static variables and fix predef allocator check. gcc/fortran/ChangeLog: * openmp.cc (is_predefined_allocator): Use gomp-constants.h consts. * trans-common.cc (translate_common): Reject OpenMP allocate directives. * trans-decl.cc (gfc_finish_var_decl): Handle allocate directive for static variables.

2024-09-23dwarf2: add hooks for architecture-specific CFIsMatthieu Longo1-0/+5
Architecture-specific CFI directives are currently declared an processed among others architecture-independent CFI directives in gcc/dwarf2* files. This approach creates confusion, specifically in the case of DWARF instructions in the vendor space and using the same instruction code. Such a clash currently happen between DW_CFA_GNU_window_save (used on SPARC) and DW_CFA_AARCH64_negate_ra_state (used on AArch64), and both having the same instruction code 0x2d. Then AArch64 compilers generates a SPARC CFI directive (.cfi_window_save) instead of .cfi_negate_ra_state, contrarilly to what is expected in [DWARF for the Arm 64-bit Architecture (AArch64)](https://github.com/ ARM-software/abi-aa/blob/main/aadwarf64/aadwarf64.rst). This refactoring does not solve completely the problem, but improve the situation by moving some of the processing of those directives (more specifically their output in the assembly) to the backend via 2 target hooks: - DW_CFI_OPRND1_DESC: parse the first operand of the directive (if any). - OUTPUT_CFI_DIRECTIVE: output the CFI directive as a string.

A few high-end nvptx devices support the attribute CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS; for those, unified shared memory is supported in hardware. This patch enables support for those - if all installed nvptx devices have this feature (as the capabilities are per device type). This exposes a bug in gomp_copy_back_icvs as it did before use omp_get_mapped_ptr to find mapped variables, but that returns the unchanged pointer in cased of shared memory. But in this case, we have a few actually mapped pointers - like the ICV variables. Additionally, there was a mismatch with regards to '-1' for the device number as gomp_copy_back_icvs and omp_get_mapped_ptr count differently. Hence, do the lookup manually. include/ChangeLog: * cuda/cuda.h (CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS): Add. libgomp/ChangeLog: * libgomp.texi (nvptx): Update USM description. * plugin/plugin-nvptx.c (GOMP_OFFLOAD_get_num_devices): Claim support when requesting USM and all devices support CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS. * target.c (gomp_copy_back_icvs): Fix device ptr lookup.

2024-04-08GCN, nvptx: Errors during device probing are fatalThomas Schwinge1-0/+1
Currently, we silently disable libgomp GCN and nvptx plugins/devices in presence of certain error conditions during device probing, thus typically silently resorting to host-fallback execution. Make such errors fatal, similar as for any other device access later on, so that we early and reliably notice when things go wrong. (Keep just two cases non-fatal: (a) libgomp GCN or nvptx plugins are available but 'libhsa-runtime64.so.1' or 'libcuda.so.1' are not, and (b) those are available, but the corresponding devices are not.) This resolves the issue that we've got execution test cases unexpectedly PASSing, despite: libgomp: GCN fatal error: Run-time could not be initialized Runtime message: HSA_STATUS_ERROR_OUT_OF_RESOURCES: The runtime failed to allocate the necessary resources. This error may also occur when the core runtime library needs to spawn threads or create internal OS-specific events. ..., and therefore they were not offloaded to the GCN device, but ran in host-fallback execution mode. What happend in that scenario is that in 'init_hsa_context' during the initial 'GOMP_OFFLOAD_get_num_devices' we ran into 'HSA_STATUS_ERROR_OUT_OF_RESOURCES', but it wasn't fatal, but just silently disabled the libgomp plugin/device. Especially "entertaining" were cases where such unintended host-fallback execution happened during effective-target checks like 'offload_device_available' (host-fallback execution there meaning: no offload device available), but actual test cases then were running with an offload device available, and therefore mis-configured. include/ * cuda/cuda.h (CUresult): Add 'CUDA_ERROR_NO_DEVICE'. libgomp/ * plugin/plugin-gcn.c (init_hsa_context): Add and handle 'bool probe' parameter. Adjust all users; errors during device probing are fatal. * plugin/plugin-nvptx.c (nvptx_get_num_devices): Aside from 'CUDA_ERROR_NO_DEVICE', errors during device probing are fatal.
