From e16b0a51be7866f3856b62b295df2bcf49e02384 Mon Sep 17 00:00:00 2001 From: Olivier Galibert Date: Tue, 8 May 2012 20:40:36 +0200 Subject: [PATCH] glsl: Bitwise conversion operator support in the software renderers. TGSI doesn't need an opcode, since registers are untyped (but beware once doubles come into the scene). Mesa IR doesn't handle native integers, so trying to handle them there is worthless, the case entries are only added for warning reasons. It was only tested with softpipe, since llvmpipe doesn't support glsl 1.3 yet.
