From b3f11165aad39586cca0352ed5fe32b721699c76 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Fri, 22 Apr 2016 16:40:33 +0100 Subject: Centralize yacc interface names remapping (yyparse, yylex, yyerror, etc) This factors out all the yy-variables remapping to a single file, instead of each parser having to do the same, with different prefixes. With this, a parser just needs to define the prefix they want and include yy-remap.h, which does the dirty job. Note this renames the c_error, ada_error, etc. functions. Writing the remapping pattern as: #define yyerror GDB_YY_REMAP (error) instead of: #define yyerror GDB_YY_REMAP (yyerror) would have avoided the renaming. However, that would be problematic if we have a macro 'foo' in scope, when we write: #define yyfoo GDB_YY_REMAP (foo) as that would expand 'foo'. The c_yyerror etc. naming end ups indicating that this is a yacc related function more clearly, so feels like a good change, anyway. gdb/ChangeLog: 2016-04-22 Pedro Alves * ada-exp.y: Remove all yy symbol remappings.
