2010-08-13glsl2: Add a generic visitor class to call back with pointers to each rvalue.Eric Anholt
I keep copy and pasting this code all over, so consolidate it in one place.
2010-08-09glsl2: Make ir_algebraic reassociate add/mul operands for constant folding.Eric Anholt
It's rather easy to produce two constant multiplies separated by other multiplies while writing a BRDF shader, and non-obvious enough in the resulting codegen that I didn't catch it in my demo code until just recently. Cuts 3 965 instructions from my demo (<1%), and 20 from glsl-fs-raytrace (1.3%).
2010-08-09ir_algebraic: Support other comparisons in ir_unop_logic_notIan Romanick
2010-08-09ir_algebraic: Convert ir_unop_logic_not handler to use a switch statementIan Romanick
Currently only ir_binop_equal and ir_binop_nequal are supported, but soon all of the relational operators will be added. Making this change now will simplify those commits.
2010-07-28ir_algebraic: Use ir_constant::zero.Kenneth Graunke
2010-07-27glsl2: Add optimization pass for algebraic simplifications.Eric Anholt
This cleans up the assembly output of almost all the non-logic tests glsl-algebraic-*. glsl-algebraic-pow-two needs love (basically, flattening to a temporary and squaring it).
