8b1680acc3 ir_constant_expression: Implement builtins that wrap an expression. 
These builtin functions are represented by ir_expression_operations, so
we can just create one of those and ask for its value.

38cb1b273f ir_constant_expression: Add support for builtins dFdx, dFdy, and fwidth. 
These always return zero (the derivative of a constant).

54f583a206 glsl2: Don't dereference a NULL var in CE handling during a compile error. 
If an undeclared variable was dereferenced in an expression that
needed constant expression handling, we would walk off a null ir->var
pointer.

Fixes:

3e882ec84a ir_constant_expression: Fix broken code for floating point modulus. 
It's supposed to be x - y * floor(x/y), not (x - y) * floor(x/y).
 2010-07-22 17:45:45 -07:00

9a6d40fbfb ir_constant_expression: Add support for array == and !=. 
Piglit parser tests const-array-03.frag and const-array-04.frag now
generate the correct code.

a096fa7476 ir_constant_expression: Add support for constant arrays. 
Fixes piglit test const-array-02.frag.

46d6b8d1ba ir_constant_expression: Add support for ir_unop_u2f. 
Also make ir_unop_i2f only operate on signed integers.

3163f87463 ir_constant_expression: Remove open coded equality comparisons. 
The ir_constant::has_value method already does this.
 2010-07-21 16:38:32 -07:00
Kenneth Graunke
e4768eecd5 ir_constant_expression: Remove pointless use of variable_referenced. 
ir_dereference_variable always references an ir_variable, so there's no
point in calling a function and NULL-checking the result.

Kenneth Graunke
98f32a13be ir_constant_expression: Use "this" pointer directly. 
In ir_expression's signature, I replaced ir->operands[i] with op[i] as
it is more concise; an assertion already ensures these are equal.

fb2ffd2846 ir_constant_expression: Convert from a visitor to a virtual function. 
The constant_expression_wrapper was already the only external API, and
much of the internal code used it anyway.  Also, it wouldn't ever visit
non-rvalue ir_instructions, so using a visitor seemed a bit unnecessary.

This uses "ir_foo *ir = this;" lines to avoid code churn.  These should
be removed.

e340854115 glsl2: Move constant_expression_value method to ir_rvalue. 
This prevents top-level callers from asking for the value of something
that is guaranteed not to have one.

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
Kenneth Graunke
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))

323d909ab2 ir_constant_expression: Add support for ir_unop_trunc. 
This uses a C99 function.

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.

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.
 2010-07-06 16:03:33 -07:00

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.
