From 73e42eef1617bcfa5b333bdb563efeea1626d112 Mon Sep 17 00:00:00 2001 From: Tobias Burnus Date: Sun, 30 Nov 2014 09:33:25 +0100 Subject: [PATCH] gfortran.h (gfc_option_t): Remove warn_aliasing, 2014-11-30 Tobias Burnus * gfortran.h (gfc_option_t): Remove warn_aliasing, * warn_ampersand, warn_function_elimination, warn_implicit_interface, warn_implicit_procedure, warn_line_truncation, warn_surprising, warn_underflow, warn_intrinsic_shadow, warn_array_temp, warn_align_commons, warn_real_q_constant, warn_unused_dummy_argument, warn_zerotrip, warn_realloc_lhs, warn_realloc_lhs_all, warn_compare_reals, warn_target_lifetime. * arith.c (check_result, gfc_real2real, gfc_real2complex, gfc_complex2real, gfc_complex2complex): Honor changed variable names. * check.c (gfc_check_transfer): Ditto. * expr.c (gfc_check_assign, gfc_check_pointer_assign): Ditto. * interface.c (compare_parameter, gfc_procedure_use, * gfc_ppc_use, gfc_arglist_matches_symbol): Ditto. * intrinsic.c (gfc_warn_intrinsic_shadow): Ditto. * primary.c (match_real_constant, match_string_constant): Ditto. * resolve.c (gfc_resolve_intrinsic, resolve_operator, gfc_resolve_iterator, resolve_select, resolve_ordinary_assign, resolve_charlen, gfc_resolve_finalizers): Ditto. * scanner.c (gfc_next_char_literal): Ditto. * simplify.c (simplify_achar_char, gfc_simplify_iachar): Ditto. * trans-array.c (gfc_trans_create_temp_array, gfc_trans_dummy_array_bias, gfc_conv_array_parameter): Ditto. * trans-common.c (translate_common): * trans-decl.c (generate_local_decl): Ditto. * trans-expr.c (realloc_lhs_warning): Ditto. * trans-intrinsic.c (gfc_conv_intrinsic_transfer): Ditto. * decl.c (do_warn_intrinsic_shadow): Ditto. Renamed from warn_intrinsic_shadow. * frontend-passes.c (do_warn_function_elimination): Honor changed variable names. Renamed from do_warn_function_elimination. * invoke.texi (Wunderflow): Document that it is enabled by * default. * lang.opt (Waliasing, Walign-commons, Warray-temporaries, Wcompare-reals, Wfunction-elimination, Wimplicit-interface, Wimplicit-procedure, Wline-truncation, Wreal-q-constant, Wrealloc-lhs, Wrealloc-lhs-all, Wtarget-lifetime, Wsurprising, Wunderflow, Wintrinsic-shadow, Wunused-dummy-argument, Wzerotrip): Use Var(), add Init() and LangEnabledBy() were required. (Wmaybe-uninitialized, Wreturn-type, Wuninitialized): Add LangEnabledBy. * options.c (gfc_init_options, gfc_post_options, * gfc_handle_option): Remove options handled in lang.opt; handle renaming. (set_Wall, set_Wextra): Remove.
