From 21b11495d75df8fd0e5b23f0176f6aa676875055 Mon Sep 17 00:00:00 2001 From: Zack Weinberg Date: Thu, 9 Sep 2004 19:16:56 +0000 Subject: cpplib.h (TTYPE_TABLE): Remove CPP_ and SPELL_ prefixes throughout. 2004-09-09 Matt Austern Zack Weinberg * include/cpplib.h (TTYPE_TABLE): Remove CPP_ and SPELL_ prefixes throughout. Add entry for PRAGMA. Remove unnecessary "= 0" from EQ. (enum cpp_ttype): Adjust OP and TK definitions to restore prefixes, via token-paste. (CPP_LAST_EQ, CPP_FIRST_DIGRAPH, CPP_LAST_PUNCTUATOR, CPP_LAST_CPP_OP): Change from #defines to additional cpp_ttype enumerators. (struct cpp_options): Add defer_pragmas. (cpp_handle_deferred_pragma): Prototype new interface. * internal.h (struct cpp_reader): Add directive_result. * directives.c (struct pragma_entry): Add is_internal field; give boolean fields type bool. (start_directive): Initialize pfile->directive_result.type. (_cpp_do__Pragma): Likewise. (run_directive): Do not crash if pfile->buffer->prev is NULL. (insert_pragma_entry): Add 'internal' argument; set new->is_internal from it. (register_pragma): New static function, bulk of former cpp_register_pragma here; add 'internal' argument, pass along to insert_pragma_entry. (cpp_register_pragma): Now a wrapper around register_pragma which always passes false for 'internal' argument. (_cpp_init_internal_pragmas): Call register_pragma directly, passing true for 'internal'. (do_pragma): If CPP_OPTION (pfile, defer_pragmas) and this isn't an internal pragma, save text till the end of the line as a CPP_PRAGMA token instead of executing the pragma. (cpp_handle_deferred_pragma): New interface. * lex.c (token_spellings): Adjust OP and TK definitions to match changes to cpplib.h. (_cpp_lex_token): Check for a directive-result token and return it if present. (cpp_token_val_index): Handle CPP_PRAGMA. * macro.c (cpp_builtin_macro_text): Correct comment. (builtin_macro): Handle directive-result tokens from _cpp_do__Pragma.
