1740aa5444 Shaders: Implemented the FSET instruction.
This instruction is similar to the FSETP instruction, but it doesn't set a predicate, it sets the destination register to 1.0 if the condition holds, and 0 otherwise.

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.

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.

d03fc77475 ShaderGen: Register id 255 is special and is hardcoded to return 0 (SR_ZERO). 2018-04-20 14:57:40 -05:00

2e0a9f66a0 ShaderGen: Ignore the 'sched' instruction when generating shaders.
The 'sched' instruction has a very convoluted encoding, but fortunately it seems to only appear on a fixed interval (once every 4 instructions).

glsl_shader_decompiler: Minor API changes to ShaderWriter

e3b6f6c016 glsl_shader_decompiler: Use std::string_view instead of std::string for AddLine()
This function doesn't need to take ownership of the string data being
given to it, considering all we do is append the characters to the
internal string instance.

Instead, use a string view to simply reference the string data without
any potential heap allocation.

Now anything that is a raw const char* won't need to be converted to a
std::string before appending.

4ef392906b glsl_shader_decompiler: Append indentation without constructing a separate std::string
