2010-09-13	glsl: introduce ir_binop_all_equal and ir_binop_any_equal, allow vector cmps	Luca Barbieri
	Currently GLSL IR forbids any vector comparisons, and defines "ir_binop_equal" and "ir_binop_nequal" to compare all elements and give a single bool. This is highly unintuitive and prevents generation of optimal Mesa IR. Hence, first rename "ir_binop_equal" to "ir_binop_all_equal" and "ir_binop_nequal" to "ir_binop_any_nequal". Second, readd "ir_binop_equal" and "ir_binop_nequal" with the same semantics as less, lequal, etc. Third, allow all comparisons to acts on vectors.

2010-09-01	glsl2: Perform algebraic simplifications on logical binary operators	Ian Romanick
	Reduces glsl-vs-all-01 from 42 Mesa IR instructions (including the END) to 17.
2010-08-17	glsl: When doing algebraic simplification, make sure the type still matches.	Eric Anholt
	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
2010-08-17	glsl: Make ir_algebraic new expressions allocate out of the parent.	Eric Anholt
	This could reduce the amount of memory used by a shader tree after optimization, and increases consistency with other passes.
2010-08-13	glsl2: 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.
2010-08-09	glsl2: 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%).
2010-08-09	ir_algebraic: Support other comparisons in ir_unop_logic_not	Ian Romanick

2010-08-09	ir_algebraic: Convert ir_unop_logic_not handler to use a switch statement	Ian 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.
2010-07-28	ir_algebraic: Use ir_constant::zero.	Kenneth Graunke

2010-07-27	glsl2: 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).
