From: Iago Toral Quiroga Date: Fri, 20 Jun 2014 08:38:53 +0000 (+0200) Subject: glsl: Modify ir_end_primitive to have a stream. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4b3fc21032a63f483d381c36c8e41bf3540ebfcc;p=mesa.git glsl: Modify ir_end_primitive to have a stream. This will be necessary to implement EndStreamPrimitive(). EndPrimitive() will produce an ir_end_primitive with the default stream 0.
