2023-06-20Fortran: Fix parse-dump-tree for OpenMP ALLOCATE clauseTobias Burnus1-3/+6
Commit r14-1301-gd64e8e1224708e added u2.allocator to gfc_omp_namelist for better readability and to permit to use namelist->expr for code like the following: !$omp allocators allocate(align(32) : dt%alloc_comp) allocate (dt%alloc_comp(5)) !$omp allocate(dt%alloc_comp2) align(64) allocate (dt%alloc_comp2(10)) However, for the parse-tree dump the change was incomplete. gcc/fortran/ChangeLog: * dump-parse-tree.cc (show_omp_namelist): Fix dump of the allocator modifier of OMP_LIST_ALLOCATE.

2023-06-19Doc update: -foffload-options= examples + OpenMP in Fortran intrinsic modulesTobias Burnus1-4/+16
With LTO, the -O.. flags of the host are passed on to the lto compiler, which also includes offloading compilers. Therefore, using --foffload-options=-O3 is misleading as it implies that without the default optimizations are used. Hence, this flags has now been removed from the usage examples. The Fortran documentation lists the content (except for API routines) routines of the intrinsic OpenMP modules OMP_LIB and OMP_LIB_KINDS; this commit adds two missing named constants and links also to the OpenMP 5.1 and 5.2 OpenMP spec for completeness. gcc/ChangeLog: * doc/invoke.texi (-foffload-options): Remove '-O3' from the examples. gcc/fortran/ChangeLog: * intrinsic.texi (OpenMP Modules OMP_LIB and OMP_LIB_KINDS): Also add references to the OpenMP 5.1 and 5.2 spec; add omp_initial_device and omp_invalid_device named constants.

2023-06-09fortran: Fix ICE on pr96024.f90 on big-endian hosts [PR96024]Jakub Jelinek1-1/+2
The pr96024.f90 testcase ICEs on big-endian hosts. The problem is that length->val.integer is accessed after checking length->expr_type == EXPR_CONSTANT, but it is a CHARACTER constant which uses length->val.character union member instead and on big-endian we end up reading constant 0x100000000 rather than some small number on little-endian and if target doesn't have enough memory for 4 times that (i.e. 16GB allocation), it ICEs. 2023-06-09 Jakub Jelinek <jakub@redhat.com> PR fortran/96024 * primary.cc (gfc_convert_to_structure_constructor): Only do constant string ctor length verification and truncation/padding if constant length has INTEGER type.

2023-06-06openmp: Add support for the 'present' modifierTobias Burnus4-14/+137
This implements support for the OpenMP 5.1 'present' modifier, which can be used in map clauses in the 'target', 'target data', 'target data enter' and 'target data exit' constructs, and in the 'to' and 'from' clauses of the 'target update' construct. It is also supported in defaultmap. The modifier triggers a fatal runtime error if the data specified by the clause is not already present on the target device.

2023-05-17Fortran/OpenMP: Fix mapping of array descriptors and deferred-length stringsTobias Burnus2-91/+247
Previously, array descriptors might have been mapped as 'alloc' instead of 'to' for 'alloc', not updating the array bounds. The 'alloc' could also appear for 'data exit', failing with a libgomp assert. In some cases, either array descriptors or deferred-length string's length variable was not mapped. And, finally, some offset calculations with array-sections mappings went wrong. Additionally, the patch now unmaps for scalar allocatables/pointers the GOMP_MAP_POINTER, avoiding stale mappings. The testcases contain some comment-out tests which require follow-up work and for which PR exist. Those mostly relate to deferred-length strings which have several issues beyong OpenMP support. gcc/fortran/ChangeLog: * trans-decl.cc (gfc_get_symbol_decl): Add attributes such as 'declare target' also to hidden artificial variable for deferred-length character variables. * trans-openmp.cc (gfc_trans_omp_array_section, gfc_trans_omp_clauses, gfc_trans_omp_target_exit_data): Improve mapping of array descriptors and deferred-length string variables. gcc/ChangeLog: * gimplify.cc (gimplify_scan_omp_clauses): Remove Fortran special case. libgomp/ChangeLog: * testsuite/libgomp.fortran/target-enter-data-3.f90: Uncomment 'target exit data'. * testsuite/libgomp.fortran/target-enter-data-4.f90: New test. * testsuite/libgomp.fortran/target-enter-data-5.f90: New test. * testsuite/libgomp.fortran/target-enter-data-6.f90: New test. * testsuite/libgomp.fortran/target-enter-data-7.f90: New test. gcc/testsuite/ * gfortran.dg/goacc/finalize-1.f: Update dg-tree; shows a fix for 'finalize' as a ptr is now 'delete' instead of 'release'. * gfortran.dg/gomp/pr78260-2.f90: Likewise as elem-size calc moved to if (allocated) block * gfortran.dg/gomp/target-exit-data.f90: Likewise as a var is now a replaced by a MEM< _25 > expression. * gfortran.dg/gomp/map-9.f90: Update dg-scan-tree-dump. * gfortran.dg/gomp/map-10.f90: New test.

2023-05-11fortran: use grep instead of fgrepXi Ruoyao1-1/+1
fgrep has been deprecated in favor of grep -F for a long time, and the curren grep release (3.10) prints a warning of fgrep is used. Stop using fgrep so we won't see the warning. We can't hard code grep -F here or it may break build on hosts w/o GNU grep. autoconf documentation contains a warning about this issue and suggest to use AC_PROG_FGREP and $FGREP, but these are too overkill in the specific case: there is no way "debian" could be interpreted as an non-trivial regex, so we can use a plain grep here. gcc/fortran/ChangeLog: * Make-lang.in: Use grep instead of fgrep.
