Subv 0369ee7248 Shaders: Added decodings for the FSET instructions. 2018-04-24 22:42:54 -05:00

bunnei 9f6d305eab shader_bytecode: Decode instructions based on bit strings. 2018-04-20 22:30:56 -04:00
Subv c3a8ea76f1 ShaderGen: Implemented predicated instruction execution.
Each predicated instruction will be wrapped in an `if (predicate) { instruction_body; }` in the GLSL, where `predicate` is one of the predicate boolean variables previously set by fsetp.

Subv 0a5e01b710 ShaderGen: Implemented the fsetp instruction.
Predicate variables are now added to the generated shader code in the form of 'pX' where X is the predicate id.
These predicate variables are initialized to false on shader startup and are set via the fsetp instructions.

TODO:

* Not all the comparison types are implemented.
* Only the single-predicate version is implemented.
