| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `__func__'. * c-decl.c (flag_isoc9x): Set to 1 by default. (c_decode_option): Handle -std= option. Remove -flang-isoc9x. (grokdeclarator): Always emit warning about implicit int for ISO C 9x. * c-parse.in: Allow constructors in ISO C 9x. Rewrite designator list handling. Allow [*] parameters. Don't warn about comma at end of enum definition for ISO C 9x. * cccp.c (c9x): New variable. (rest_extension): New variable. (print_help): Document new -std= option. (main): Recognize -std= option. Set c9x appropriately. (create_definition): Recognize ISO C 9x vararg macros. * gcc.c (default_compilers): Adjust specs for -std options. (option_map): Add --std. (display_help): Document -std. * toplev.c (documented_lang_options): Add -std and remove -flang-isoc9x. * c-lex.c (yylex): Recognize hex FP constants and call REAL_VALUE_ATOF or REAL_VALUE_HTOF based on base of the constants. * fold-const.c (real_hex_to_f): New function. Replacement function for hex FP conversion if REAL_ARITHMETIC is not defined. * real.c (asctoeg): Add handling of hex FP constants. * real.h: Define REAL_VALUE_HTOF if necessary using ereal_atof or real_hex_to_f. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@24049 138bc75d-0d04-0410-961f-82ee72b054a4
