*	glsl: When doing algebraic simplification, make sure the type still matches.	Eric Anholt	2010-08-17	1	-12/+34
\| \| \| \| \| \| \| \| \| \| \| \|	When simplifying (vec4(1.0) / (float(x))) to rcp(float(x)), we forgot to produce a vec4, angering ir_validate when starting alien-arena. Fixes: glsl-algebraic-add-zero-2 glsl-algebraic-div-one-2 glsl-algebraic-mul-one-2 glsl-algebraic-sub-zero-3 glsl-algebraic-rcp-sqrt-2
*	glsl: Make ir_algebraic new expressions allocate out of the parent.	Eric Anholt	2010-08-17	1	-16/+22
\| \| \| \| \|	This could reduce the amount of memory used by a shader tree after optimization, and increases consistency with other passes.
*	glsl2: Add a generic visitor class to call back with pointers to each rvalue.	Eric Anholt	2010-08-13	1	-105/+15
\| \| \| \| \|	I keep copy and pasting this code all over, so consolidate it in one place.
*	glsl2: Make ir_algebraic reassociate add/mul operands for constant folding.	Eric Anholt	2010-08-09	1	-1/+107
\| \| \| \| \| \| \| \|	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%).
*	ir_algebraic: Support other comparisons in ir_unop_logic_not	Ian Romanick	2010-08-09	1	-0/+4

*	ir_algebraic: Convert ir_unop_logic_not handler to use a switch statement	Ian Romanick	2010-08-09	1	-9/+19
\| \| \| \| \| \|	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.
*	ir_algebraic: Use ir_constant::zero.	Kenneth Graunke	2010-07-28	1	-6/+2
\|
*	glsl2: Add optimization pass for algebraic simplifications.	Eric Anholt	2010-07-27	1	-0/+366
	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).
