From: Marek Olšák Date: Wed, 6 Aug 2014 21:58:10 +0000 (+0200) Subject: gallium: remove PIPE_SHADER_CAP_MAX_ADDRS X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c10332bbb8889d733bdaa729ef23cbd90176b55d;p=mesa.git gallium: remove PIPE_SHADER_CAP_MAX_ADDRS This limit is fixed in Mesa core and cannot be changed. It only affects ARB_vertex_program and ARB_fragment_program. The minimum value for ARB_vertex_program is 1 according to the spec. The maximum value for ARB_vertex_program is limited to 1 by Mesa core. The value should be zero for ARB_fragment_program, because it doesn't support ARL. Finally, drivers shouldn't mess with these values arbitrarily.
