From 7ec0c9789669ac88fcdd66c562e6d58281b477ce Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Sat, 9 Apr 2011 10:27:02 -1000 Subject: [PATCH] glsl: Semantically check the RHS of `&&' even when short-circuiting. We just do the AST-to-HIR processing, and only push the instructions if needed in the constant true case.
