OpenMP: Support strided and shaped-array updates for C++
This patch adds support for OpenMP 5.0 strided updates and the
array-shaping operator ("([x][y][z]) foo[0:n]..."). This is mostly for
C++ only so far, though necessary changes have been made to the C FE to
adjust for changes to shared data structures.
In terms of the implementation of various bits:
- The OMP_ARRAY_SECTION tree code has been extended to take a 'stride'
argument, and changes have been made throughout semantics.cc, etc. to
take the new field into account -- including bounds checking.
- A new type of cast operator has been added to represent the OpenMP
array-shaping operator: OMP_ARRAYSHAPE_CAST_EXPR (1).
- The address tokenization mechanism from previous patches has been
extended with two new access kinds to represent noncontiguous array
updates.
- New mapping kinds have been added to represent noncontiguous updates:
those which may be subject to array shaping, or have non-unit strides.
These are processed by omp-low.cc into a kind of descriptor that is
passed to the libgomp runtime (2).
The current patch reuses an extended version of the helper code for
omp_target_memcpy_rect, which may generate very many small host-device or
device-host copies. (The "descriptor" has also been designed so reusing
that functionality is relatively straightforward.) Optimising those
multiple copies, e.g. by packing them into a single transfer when it
would be beneficial, is left as the subject of a future patch.
This patch has some adjustments to the omp-low.cc code after Chung-Lin's
patch "OpenMP 5.0: Allow multiple clauses mapping same variable"

OpenMP: C++ "declare mapper" support
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.

OpenACC: Improve implicit mapping for non-lexically nested offload regions
This patch enables use of the OMP_CLAUSE_RUNTIME_IMPLICIT_P flag for
OpenACC.
This allows code like this to work correctly:
int arr[100];
[...]
#pragma acc enter data copyin(arr[20:10])
/* No explicit mapping of 'arr' here. */
#pragma acc parallel
{ /* use of arr[20:10]... */ }
#pragma acc exit data copyout(arr[20:10])
Otherwise, the implicit "copy" ("present_or_copy") on the parallel
corresponds to the whole array, and that fails at runtime when the
subarray is mapped.
The numbering of the GOMP_MAP_IMPLICIT bit clashes with the OpenACC
"non-contiguous" dynamic array support, so the GOMP_MAP_NONCONTIG_ARRAY_P
macro has been adjusted to account for that.
gcc/
* gimplify.cc (gimplify_adjust_omp_clauses_1): Set
OMP_CLAUSE_MAP_RUNTIME_IMPLICIT_P for OpenACC also.

OpenMP: 'interop' construct - add ME support + target-independent libgomp
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.

Synchronize include/dwarf2.def with binutils
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. |

dwarf2out: Emit DWARF 6 DW_AT_language_{name,version}
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.

OpenMP: 'interop' construct - add C/C++ parser support, improve Fortran parsing
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_parser_omp_clause_init, c_parser_omp_clause_use,
OMP_INTEROP_CLAUSE_MASK, c_parser_omp_interop): New.
* c-typeck.cc (c_finish_omp_clauses): Add missing OPT_Wopenmp to
a warning; handle new clauses.

and destroy clauses.

include: Add new post-DWARF 5 DW_LANG_* enumerators
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>

the post DWARF 5 additions start. Refresh list from

non-gcc: Remove trailing whitespace
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:

OpenMP: Allocate directive for static vars, clean up
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.
(gfc_trans_deferred_vars): Update for the latter.
gcc/ChangeLog:
* gimplify.cc (gimplify_bind_expr): Fix corner case for OpenMP
allocate directive.
(gimplify_scan_omp_clauses): Warn if omp_thread_mem_alloc is used
as allocator with the target/task/taskloop directive.
include/ChangeLog:
* gomp-constants.h (GOMP_OMP_PREDEF_ALLOC_MAX,
GOMP_OMPX_PREDEF_ALLOC_MIN, GOMP_OMPX_PREDEF_ALLOC_MAX,
GOMP_OMP_PREDEF_ALLOC_THREADS): New defines.
libgomp/ChangeLog:
* allocator.c: Add static asserts for news
GOMP_OMP{,X}_PREDEF_ALLOC_{MIN,MAX} range values.
* libgomp.texi (OpenMP Impl. Status): Allocate directive for
static vars is now supported. Refer to PR for allocate clause.
(Memory allocation): Update for static vars; minor word tweaking.

* c-c++-common/gomp/allocate-9.c: Update for removed sorry.

dwarf2: add hooks for architecture-specific CFIs
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. (aarch64_dw_cfi_oprnd1_desc): Same. (TARGET_OUTPUT_CFI_DIRECTIVE): Hook for output_cfi_directive.
