9be7f63813 glsl2: Make cross() be an expression operation. 
ARB_fp, ARB_vp, Mesa IR, and the 965 vertex shader all have
instructions for cross.  Shaves 12 Mesa instructions off of a
66-instruction shader I have.

ce5ae5f49d ir_constant_expression: Add support for ir_binop_mod. 2010-07-14 16:49:24 -07:00

79fed377f4 ir_constant_expression: Add support for ir_binop_min and ir_binop_max. 
These now work on scalar/vector combos. Semantically, if a is a scalar,
min(a, vec2(x,y)) == vec2(min(a,x), min(a,y))

5e840dba44 ir_constant_expression: Remove bogus assert in ir_unop_abs case. 
abs is defined for integral types; it's even implemented.

ca088cc277 glsl2: Clone methods return the type of the thing being cloned 
This is as opposed to returning the type of the base class of the hierarchy.

f14e596f11 ir_constant_expression: Declare loop counting variables in the loops. 
Fixes "name lookup of 'c' changed" warning.

cf80a4d177 ir_constant_expression: Add support for matrix multiplication. 
Also handles matrix/vector and vector/matrix multiplication.

Fixes piglit tests const-matrix-multiply-01.frag,
const-matrix-multiply-02.frag, and const-vec-mat.frag.

37b3f9d0ed ir_constant_expression: Support scalar * vector and scalar * matrix. 
The test here is slightly different since we need to keep matrix
multiplication separate.

Fixes piglit tests const-vec-scalar-03.frag and const-mat-scalar-03.frag.

6bc432e14e ir_constant_expression: Initialize op[0] and op[1] to NULL. 
This makes it easy to check if there is a second argument.

c63a1db81f ir_constant_expression: Initialize all components of constant data to 0. 
This is probably just a good idea, and will come in useful when
implementing things like matrix multiplication.

d925c91730 glsl2: Add ir_unop_fract as an expression type. 
Most backends will prefer seeing this to seeing (a - floor(a)), so
represent it explicitly.
