2020-11-06Fortran: Fix type-decl for PDT / wrong-code pdt_14.f03 issue [PR97652]Tobias Burnus1-0/+3
Parameterized derived types are handled in a special way and start with 'Pdt'. If the 'P' is not uppercase, gfc_get_derived_type (which calls gfc_get_module_backend_decl) does not find the existing declaration and builds a new type. The middle end then sees those types as being different and nonalising, creating an endless loop for pdt_14.f03. gcc/fortran/ChangeLog: PR fortran/97652 * module.c (mio_symbol): Fix symbol name for pdt_type.

2020-03-17Fix up duplicated duplicated words mostly in commentsJakub Jelinek1-2/+2
In the r10-7197-gbae7b38cf8a21e068ad5c0bab089dedb78af3346 commit I've noticed duplicated word in a message, which lead me to grep for those and we have a tons of them. I've used grep -v 'long long\|optab optab\|template template\|double double' *.[chS] */*.[chS] *.def config/*/* 2>/dev/null | grep ' \([a-zA-Z]\+\) \1 ' Note, the command will not detect the doubled words at the start or end of line or when one of the words is at the end of line and the next one at the start of another one. Some of it is fairly obvious, e.g. all the "the the" cases which is something I've posted and committed patch for already e.g. in 2016, other cases are often valid, e.g. "that that" seems to look mostly ok to me. Some cases are quite hard to figure out, I've left out some of them from the patch (e.g. "and and" in some cases isn't talking about bitwise/logical and and so looks incorrect, but in other cases it is talking about those operations). In most cases the right solution seems to be to remove one of the duplicated words, but not always. I think most important are the ones with user visible messages (in the patch 3 of the first 4 hunks), the rest is just comments (and internal documentation; for that see the doc/tm.texi changes). 2020-03-17 Jakub Jelinek <jakub@redhat.com> * lra-spills.c (remove_pseudos): Fix up duplicated word issue in a dump message. * tree-sra.c (create_access_replacement): Fix up duplicated word issue in a comment. * read-rtl-function.c (find_param_by_name, function_reader::parse_enum_value, function_reader::get_insn_by_uid): Likewise. * spellcheck.c (get_edit_distance_cutoff): Likewise. * tree-data-ref.c (create_ifn_alias_checks): Likewise. * tree.def (SWITCH_EXPR): Likewise. * selftest.c (assert_str_contains): Likewise. * ipa-param-manipulation.h (class ipa_param_body_adjustments): Likewise. * tree-ssa-math-opts.c (convert_expand_mult_copysign): Likewise. * tree-ssa-loop-split.c (find_vdef_in_loop): Likewise. * langhooks.h (struct lang_hooks_for_decls): Likewise. * ipa-prop.h (struct ipa_param_descriptor): Likewise. * tree-ssa-strlen.c (handle_builtin_string_cmp, handle_store): Likewise. * tree-ssa-dom.c (simplify_stmt_for_jump_threading): Likewise. * tree-ssa-reassoc.c (reassociate_bb): Likewise. * tree.c (component_ref_size): Likewise. * hsa-common.c (hsa_init_compilation_unit_data): Likewise. * gimple-ssa-sprintf.c (get_string_length, format_string, format_directive): Likewise. * omp-grid.c (grid_process_kernel_body_copy): Likewise. * input.c (string_concat_db::get_string_concatenation, test_lexer_string_locations_ucn4): Likewise. * cfgexpand.c (pass_expand::execute): Likewise. * gimple-ssa-warn-restrict.c (builtin_memref::offset_out_of_bounds, maybe_diag_overlap): Likewise. * rtl.c (RTX_CODE_HWINT_P_1): Likewise. * shrink-wrap.c (spread_components): Likewise. * tree-ssa-dse.c (initialize_ao_ref_for_dse, valid_ao_ref_for_dse): Likewise. * tree-call-cdce.c (shrink_wrap_one_built_in_call_with_conds): Likewise. * dwarf2out.c (dwarf2out_early_finish): Likewise. * gimple-ssa-store-merging.c: Likewise. * ira-costs.c (record_operand_costs): Likewise. * tree-vect-loop.c (vectorizable_reduction): Likewise. * target.def (dispatch): Likewise.

In order to handle large character lengths on (L)LP64 targets, switch the GFortran character length from an int to a size_t. This is an ABI change, as procedures with character arguments take hidden arguments with the character length. I also changed the _size member in vtables from int to size_t, as there were some cases where character lengths and sizes were apparently mixed up and caused regressions otherwise. Although I haven't tested, this might enable very large derived types as well. Also, as there are some places in the frontend were negative character lengths are used as special flag values, in the frontend the character length is handled as a signed variable of the same size as a size_t, although in the runtime library it really is size_t. I haven't changed the character length variables for the co-array intrinsics, as this is something that may need to be synchronized with OpenCoarrays. This is v5 of the patch. v4 was applied but caused breakage on big endian targets. These have been fixed and tested, thanks to access to the GCC compile farm. Overview of v4 of the patch: v3 was applied but had to reverted due to breaking bootstrap. The fix is in resolve.c:resolve_charlen, where it's necessary to check that an expression is constant before using mpz_sgn. Overview of v3 of the patch: All the issues pointed out by FX's review of v2 have been fixed. In particular, there are now new functions gfc_mpz_get_hwi and gfc_mpz_set_hwi, similar to the GMP functions mpz_get_si and mpz_set_si, except that they get/set a HOST_WIDE_INT instead of a long value. Similarly, gfc_get_int_expr now takes a HOST_WIDE_INT instead of a long, gfc_extract_long is replaced by gfc_extract_hwi. Also, the preliminary work to handle gfc_charlen_type_node being unsigned has been removed. Regtested on x86_64-pc-linux-gnu, i686-pc-linux-gnu and powerpc64-unknown-linux-gnu. Also regtested all three targets by modifying gfortran-dg.exp to also test with "-g -flto", no new failures observed. frontend: 2018-01-05 Janne Blomqvist <jb@gcc.gnu.org> PR fortran/78534 PR fortran/66310 * array.c (got_charlen): Use gfc_charlen_int_kind. * class.c (gfc_find_derived_vtab): Use gfc_size_kind instead of hardcoded kind.

In order to handle large character lengths on (L)LP64 targets, switch the GFortran character length from an int to a size_t. This is an ABI change, as procedures with character arguments take hidden arguments with the character length. I also changed the _size member in vtables from int to size_t, as there were some cases where character lengths and sizes were apparently mixed up and caused regressions otherwise. Although I haven't tested, this might enable very large derived types as well. Also, as there are some places in the frontend were negative character lengths are used as special flag values, in the frontend the character length is handled as a signed variable of the same size as a size_t, although in the runtime library it really is size_t. I haven't changed the character length variables for the co-array intrinsics, as this is something that may need to be synchronized with OpenCoarrays. This is v4 of the patch. v3 was applied but had to reverted due to breaking bootstrap. The fix is in resolve.c:resolve_charlen, where it's necessary to check that an expression is constant before using mpz_sgn. Overview of v3 of the patch: All the issues pointed out by FX's review of v2 have been fixed. In particular, there are now new functions gfc_mpz_get_hwi and gfc_mpz_set_hwi, similar to the GMP functions mpz_get_si and mpz_set_si, except that they get/set a HOST_WIDE_INT instead of a long value. Similarly, gfc_get_int_expr now takes a HOST_WIDE_INT instead of a long, gfc_extract_long is replaced by gfc_extract_hwi. Also, the preliminary work to handle gfc_charlen_type_node being unsigned has been removed.
