From b6bdcf2a908889532ef6d5eb643791176dffcb9d Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Thu, 18 Aug 2011 00:18:15 -0700 Subject: [PATCH] i965/fs: Rudimentary support for non-floating point texture results. Not all texturing operations return floating point data. For example, the resinfo message (textureSize or TXS) returns integer data. In the future, we'll also add integer texture support. ir_texture's type field contains this information; use its base type to appropriately type the destination register. We want to keep it as a four component vector, however, since SIMD8 samplers always have a response length of 4.
