2021-04-26Simplify {gimplify_and_,}update_call_from_tree APIRichard Biener1-2/+1
This removes update_call_from_tree in favor of gimplify_and_update_call_from_tree, removing some code duplication and simplifying the API use. Some users of update_call_from_tree have been transitioned to replace_call_with_value and the API and its dependences have been moved to gimple-fold.h. This shaves off another user of valid_gimple_rhs_p which is now only used from within gimple-fold.c and thus moved and made private. 2021-04-14 Richard Biener <rguenther@suse.de> * tree-ssa-propagate.h (valid_gimple_rhs_p): Remove.

2020-03-17Fix up duplicated duplicated words mostly in commentsJakub Jelinek1-3/+3
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.

long and cumbersome. The base class for ranges is currently value_range_base, which is rather long and cumbersome. It also occurs more often than the derived class of value_range. To avoid confusion, and save typing, this patch does a global rename from value_range to value_range_equiv, and from value_range_base to value_range. This way, the base class is simply value_range, and the derived class is value_range_equiv which explicitly states what it does. From-SVN: r277847
