From: Nicolai Hähnle Date: Wed, 19 Apr 2017 08:08:25 +0000 (+0200) Subject: glsl: add intrinsics for ARB_shader_group_vote and ARB_shader_ballot X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=99941a97241e550985e8e5624e4959835eb0cd6b;p=mesa.git glsl: add intrinsics for ARB_shader_group_vote and ARB_shader_ballot These operations are currently implemented as IR expressions. However, they cannot be transformed and moved in the way that other IR expressions can because they have non-trivial interactions with control-flow.
