* glsl2: Remove the const disease from function signature's callee.Eric Anholt2010-07-181-1/+1
|
* glsl2: Make cross() be an expression operation.Eric Anholt2010-07-181-0/+2
| | | | | | 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.
* ir_function_signature: Add method to get the function owning a signatureIan Romanick2010-07-121-1/+1
| | | | | | | | | There is no setter function, the getter returns a constant pointer, and ir_function_signature::_function is private for a reason. The only way to make a connection between a function and function signature is via ir_function::add_signature. This helps ensure that certain invariants (i.e., a function signature is in the list of signatures for its _function) are met.
* ir_call: Add method to set the function signature being calledIan Romanick2010-07-121-0/+8

* glsl2: Add ir_unop_fract as an expression type.Eric Anholt2010-07-011-0/+2
| | | | | Most backends will prefer seeing this to seeing (a - floor(a)), so represent it explicitly.
* glsl2: Make function names and variable names be children of the node.Eric Anholt2010-06-301-3/+2
| | | | This avoids losing their memory when the parser state is freed.
* ir_swizzle: Add new constructor, refactor constructorsIan Romanick2010-06-291-18/+45
| | | | | Adds a new constructor that takes an array of component values. Refactors the meat of the two constructors to an init_mask method.
* glsl2: Move the compiler to the subdirectory it will live in in Mesa.Eric Anholt2010-06-241-0/+818
