From 12c5175d68a840960e4cf7d3001c926f15c4d006 Mon Sep 17 00:00:00 2001 From: Mark Kettenis Date: Wed, 5 Feb 2014 13:30:33 +0100 Subject: [PATCH] Avoid bison-isms when using yacc. YYPRINT is a bison-ism so c_print_token() ends up being unused when yacc is used which makes gcc unhappy. Make sure we only define YYPRINT and c_print_token() when bison is used to generate the parser. gdb/ChangeLog: * c-exp.y (YYPRINT, c_print_token): Only define if YYBISON is defined. --- gdb/ChangeLog | 5 +++++ gdb/c-exp.y | 6 ++++++ 2 files changed, 11 insertions(+) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index a6fa6fcd4dd..fcec3552231 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,8 @@ +2014-02-05 Mark Kettenis + + * c-exp.y (YYPRINT, c_print_token): Only define if YYBISON is + defined. + 2014-02-05 Yao Qi * remote.c (remote_pass_signals): Remove local 'buf' and use diff --git a/gdb/c-exp.y b/gdb/c-exp.y index 277242ea08b..4704845e203 100644 --- a/gdb/c-exp.y +++ b/gdb/c-exp.y @@ -169,8 +169,10 @@ static struct stoken operator_stoken (const char *); static void check_parameter_typelist (VEC (type_ptr) *); static void write_destructor_name (struct stoken); +#ifdef YYBISON static void c_print_token (FILE *file, int type, YYSTYPE value); #define YYPRINT(FILE, TYPE, VALUE) c_print_token (FILE, TYPE, VALUE) +#endif %} %type exp exp1 type_exp start variable qualified_name lcurly @@ -3201,6 +3203,8 @@ c_parse (void) return result; } +#ifdef YYBISON + /* This is called via the YYPRINT macro when parser debugging is enabled.
