From b4a08a0d87908b024a3d2595073b1beb6eda161e Mon Sep 17 00:00:00 2001 From: Carl Worth Date: Wed, 21 Jul 2010 13:11:46 -0700 Subject: [PATCH] Avoid more warnings in flex-generated code. This avoids two "function defined but not used" warnings. For the yyinput function we define YY_NO_INPUT which tells flex to simply not generate this function. For unput, we add a call to this function, but inside a while(0) so that it will quiet the warning without actually changing any functionality. --- src/mesa/program/program_lexer.l | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/src/mesa/program/program_lexer.l b/src/mesa/program/program_lexer.l index a9125171650..0a50dab97fd 100644 --- a/src/mesa/program/program_lexer.l +++ b/src/mesa/program/program_lexer.l @@ -139,6 +139,13 @@ handle_ident(struct asm_parser_state *state, const char *text, YYSTYPE *lval) } \ } while(0); +#define YY_NO_INPUT + +/* Yes, this is intentionally doing nothing.
