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.

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

math_util: Remove the Clamp() function
C++17 adds clamp() to the standard library, so we can remove ours in
favor of it.

Lioncash d9e316e353 common_funcs: Remove ARRAY_SIZE macro
C++17 has non-member size() which we can just call where necessary.

glsl_shader_decompiler: Minor API changes to ShaderWriter
2018-04-19 21:09:25 -04:00
Lioncash 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.

Lioncash 4ef392906b glsl_shader_decompiler: Append indentation without constructing a separate std::string
The interface of std::string already lets us append N copies of a
character to an existing string.

Subv 5367935d35 ShaderGen: Fixed a case where the TEXS instruction would use the same registers for the input and the output.
It will now save the coords before writing the outputs in a subscope.

TODO: The way we handle cached formats must change, framebuffer and texture formats are too different to keep them in the same place.

Subv 7fc516cc1a MaxwellToGL: Added a TODO and partial implementation of maxwell wrap mode 4 (Clamp, GL_CLAMP).
This clamp mode was removed from OpenGL as of 3.1, we can emulate it by using GL_CLAMP_TO_BORDER to get the border color of the texture, and then manually sampling the edge to mix them in the fragment shader.
