10 dayslibiberty: add routines to handle type-sensitive doubly linked listsMatthieu Longo1-0/+447
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.

2025-06-19[PATCH] RISC-V: Use builtin clz/ctz when count_leading_zeros and ↵Sosutha Sethuramapandian1-0/+14
count_trailing_zeros is used longlong.h for RISCV should define count_leading_zeros and count_trailing_zeros and COUNT_LEADING_ZEROS_0 when ZBB is enabled. The following patch patch fixes the bug reported in, https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110181 The divdi3 on riscv32 with zbb extension generates __clz_tab instead of genearating __builtin_clzll/__builtin_clz which is not efficient since lookup table is emitted. Updating longlong.h to use this __builtin_clzll/__builtin_clz generates optimized code for the instruction. PR target/110181 include/ChangeLog * longlong.h [__riscv] (count_leading_zeros): Define.

This patch adds support for OpenMP 5.0 "declare mapper" functionality for C++. I've merged it to og13 based on the last version posted upstream, with some minor changes due to the newly-added 'present' map modifier support. There's also a fix to splay-tree traversal in gimplify.cc:omp_instantiate_implicit_mappers, and this patch omits the rearrangement of gimplify.cc:gimplify_{scan,adjust}_omp_clauses that I separated out into its own patch and applied (to og13) already. gcc/c-family/ * c-common.h (c_omp_region_type): Add C_ORT_DECLARE_MAPPER and C_ORT_OMP_DECLARE_MAPPER codes.

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.

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 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.

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. Additionally, this patch also contains a renaming of an enum used for return address mangling on AArch64. gcc/ChangeLog: * config/aarch64/aarch64.cc (aarch64_output_cfi_directive): New hook for CFI directives.

2024-07-02ctf: use pointers instead of IDs internallyDavid Faust1-0/+5
This patch replaces all inter-type references in the ctfc internal data structures with pointers, rather than the references-by-ID which were used previously. A couple of small updates in the BPF backend are included to make it compatible with the change. This change is only to the in-memory representation of various CTF structures to make them easier to work with in various cases. It is outwardly transparent; there is no change in emitted CTF. gcc/ * btfout.cc (BTF_VOID_TYPEID, BTF_INIT_TYPEID): Move defines to include/btf.h.

2024-05-29libgomp: Enable USM for AMD APUs and MI200 devicesTobias Burnus1-1/+3
If HSA_AMD_SYSTEM_INFO_SVM_ACCESSIBLE_BY_DEFAULT is true, all GPUs on the system support unified shared memory. That's the case for APUs and MI200 devices when XNACK is enabled. XNACK can be enabled by setting HSA_XNACK=1 as env var for supported devices; otherwise, if disable, USM code will use host fallback. gcc/ChangeLog: * config/gcn/gcn-hsa.h (gcn_local_sym_hash): Fix typo. include/ChangeLog: * hsa.h (HSA_AMD_SYSTEM_INFO_SVM_ACCESSIBLE_BY_DEFAULT): Add enum value. libgomp/ChangeLog: * libgomp.texi (gcn): Update USM handling * plugin/plugin-gcn.c (GOMP_OFFLOAD_get_num_devices): Handle USM if HSA_AMD_SYSTEM_INFO_SVM_ACCESSIBLE_BY_DEFAULT is true.
2024-05-29libgomp: Enable USM for some nvptx devicesTobias Burnus1-1/+2
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. (gomp_target_init): Set GOMP_OFFLOAD_CAP_SHARED_MEM is the devices supports USM.
