From: Bryan Cain Date: Tue, 17 May 2011 22:13:20 +0000 (-0500) Subject: mesa: support boolean and integer-based parameters in prog_parameter X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6d89abadbcd68bbe9e08f041412549f8dc1fc73c;p=mesa.git mesa: support boolean and integer-based parameters in prog_parameter The functionality is not used by anything yet, and the glUniform functions will need to be reworked before this can reach its full usefulness. It is nonetheless a step towards integer support in the state tracker and classic drivers. --- diff --git a/src/mesa/main/ff_fragment_shader.cpp b/src/mesa/main/ff_fragment_shader.cpp index 0b53c28f7ae..2ccbaf8f8c3 100644 --- a/src/mesa/main/ff_fragment_shader.cpp +++ b/src/mesa/main/ff_fragment_shader.cpp @@ -875,7 +875,8 @@ static struct ureg register_const4f( struct texenv_fragment_program *p, values[1] = s1;
