2025-11-13openmp, nvptx: ompx_gnu_managed_mem_allocAndrew Stubbs
This adds support for using Cuda Managed Memory with omp_alloc. AMD support will be added in a future patch. There is one new predefined allocator, "ompx_gnu_managed_mem_alloc", plus a corresponding memory space, which can be used to allocate memory in the "managed" space. The nvptx plugin is modified to make the necessary Cuda calls, via two new (optional) plugin interfaces. gcc/fortran/ChangeLog: * openmp.cc (is_predefined_allocator): Use GOMP_OMP_PREDEF_ALLOC_MAX and GOMP_OMPX_PREDEF_ALLOC_MIN/MAX instead of hardcoded values in the comment. include/ChangeLog: * cuda/cuda.h (cuMemAllocManaged): Add declaration and related CU_MEM_ATTACH_GLOBAL flag. * gomp-constants.h (GOMP_OMPX_PREDEF_ALLOC_MAX): Update to 201.

2025-10-09dwarf: create annotation DIEs for btf tagsDavid Faust
The btf_decl_tag and btf_type_tag attributes provide a means to annotate declarations and types respectively with arbitrary user provided strings. These strings are recorded in debug information for post-compilation uses, and despite the name they are meant to be recorded in DWARF as well as BTF. New DWARF extensions DW_TAG_GNU_annotation and DW_AT_GNU_annotation are used to represent these user annotations in DWARF. This patch introduces the new DWARF extension DIE and attribute, and generates them as necessary to represent user annotations from btf_decl_tag and btf_type_tag. The format of the new DIE is as follows: DW_TAG_GNU_annotation DW_AT_name: "btf_decl_tag" or "btf_type_tag" DW_AT_const_value: <arbitrary user-supplied string> DW_AT_GNU_annotation: <reference to another TAG_GNU_annotation DIE> DW_AT_GNU_annotation is a new attribute extension used to refer to these new annotation DIEs. If non-null in any given declaration or type DIE, it is a reference to a DW_TAG_GNU_annotation DIE holding an annotation for that declaration or type. In addition, the DW_TAG_GNU_annotation DIEs may also have a non-null DW_AT_GNU_annotation, referring to another annotation DIE. This allows chains of annotation DIEs to be formed, such as in the case where a single declaration has multiple instances of btf_decl_tag with different string annotations. gcc/ * dwarf2out.cc (struct annotation_node, struct annotation_node_hasher) (btf_tag_htab): New ancillary structures and hash table.

2025-08-17c++: Implement P2115R0 linkage changes for unnamed unscoped enums [PR120503]Nathaniel Shead
We currently list P2115R0 as implemented, but only the modules changes had been done. This patch implements the linkage changes so that unnamed unscoped enums will use the name of the first enumerator for linkage purposes. This is (strictly speaking) a breaking change, as code that previously relied on unnamed enumerations being internal linkage may have overloads using those types become exposed and clash with other functions in a different TU that have been similarly exposed. As such this feature is only implemented for C++20. No ABI flag warning is provided, partly because C++20 is still an experimental standard, but also because any affected functions could not have been part of an ABI until this change anyway. A number of testcases that are testing for behaviour of no-linkage types are adjusted to use an enumeration with no values, so that the pre-C++20 and post-C++20 behaviour is equivalently tested. In terms of implementation, I had originally considered adjusting the DECL_NAME of the enum, as with 'name_unnamed_type', but this ended up being more complicated as it had unwanted interactions with the existing modules streaming and with name lookup and diagnostic messages. This patch instead uses a new function to derive this case. The standard says that ([dcl.enum] p11) such an enum "...is denoted, for linkage purposes, by its underlying type and its first enumerator", so we need to add a new mangling production as well to handle this.

2025-07-09libiberty: add routines to handle type-sensitive doubly linked listsMatthieu Longo
Those methods's implementation is relying on duck-typing at compile time. The structure corresponding to the node of a doubly linked list needs to define attributes 'prev' and 'next' which are pointers on the type of a node. The structure wrapping the nodes and others metadata (first, last, size) needs to define pointers 'first', and 'last' of the node's type, and an integer type for 'size'. Mutative methods can be bundled together and be declarable once via a same macro, or can be declared separately. The merge sort is bundled separately. There are 3 types of macros: 1. for the declaration of prototypes: to use in a header file for a public declaration, or as a forward declaration in the source file for private declaration. 2. for the declaration of the implementation: to use always in a source file. 3. for the invocation of the functions. The methods can be declared either public or private via the second argument of the declaration macros. List of currently implemented methods: - LINKED_LIST_*: - APPEND: insert a node at the end of the list. - PREPEND: insert a node at the beginning of the list. - INSERT_BEFORE: insert a node before the given node. - POP_FRONT: remove the first node of the list. - POP_BACK: remove the last node of the list. - REMOVE: remove the given node from the list. - SWAP: swap the two given nodes in the list. - LINKED_LIST_MERGE_SORT: a merge sort implementation. include/ChangeLog: * doubly-linked-list.h: New file. libiberty/ChangeLog: * Makefile.in: Add new header. * testsuite/Makefile.in: Add new test. * testsuite/test-doubly-linked-list.c: New test.

2025-01-08dwarf2out: Emit DWARF 6 DW_AT_language_{name,version}Jakub Jelinek
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 Burnus
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.

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.

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 Jelinek
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 Burnus
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.

2024-09-24OpenMP: Add support for 'self_maps' to the 'require' directiveTobias Burnus
'self_maps' implies 'unified_shared_memory', except that the latter also permits that explicit maps copy data to device memory while self_maps does not. In GCC, currently, both are handled identical. gcc/c/ChangeLog: * c-parser.cc (c_parser_omp_requires): Handle self_maps clause. gcc/cp/ChangeLog: * parser.cc (cp_parser_omp_requires): Handle self_maps clause. gcc/fortran/ChangeLog: * gfortran.h (enum gfc_omp_requires_kind): Add OMP_REQ_SELF_MAPS.
