Kenneth Graunke	1e3bcbdf31	glsl: Add a new ir_txs (textureSize) opcode to ir_texture. ... One unique aspect of TXS is that it doesn't have a coordinate.

Kenneth Graunke	c5a27b5939	glsl: Change texel offsets to a single vector rvalue. ... Having these as actual integer values makes it difficult to implement the texture*Offset built-in functions, since the offset is actually a function parameter (which doesn't have a constant value). The original rationale was that some hardware needs these offset baked into the instruction opcode. However, at least i965 should be able to support non-constant offsets. Others should be able to rely on inlining and constant propagation.	2011-01-31 11:10:59 -08:00

Eric Anholt	b3b0cf6a4c	glsl2: Add a generic visitor class to call back with pointers to each rvalue. ... I keep copy and pasting this code all over, so consolidate it in one place.	2010-08-13 17:54:46 -07:00
