*	shader/texture: Join separate image and sampler pairs offline	ReinUsesLisp	2020-06-05	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Games using D3D idioms can join images and samplers when a shader executes, instead of baking them into a combined sampler image. This is also possible on Vulkan. One approach to this solution would be to use separate samplers on Vulkan and leave this unimplemented on OpenGL, but we can't do this because there's no consistent way of determining which constant buffer holds a sampler and which one an image. We could in theory find the first bit and if it's in the TIC area, it's an image; but this falls apart when an image or sampler handle use an index of zero. The used approach is to track for a LOP.OR operation (this is done at an IR level, not at an ISA level), track again the constant buffers used as source and store this pair. Then, outside of shader execution, join the sample and image pair with a bitwise or operation. This approach won't work on games that truly use separate samplers in a meaningful way. For example, pooling textures in a 2D array and determining at runtime what sampler to use. This invalidates OpenGL's disk shader cache :) - Used mostly by D3D ports to Switch

*	shader: Move Node declarations out of the shader IR header	ReinUsesLisp	2019-06-07	1	-1/+6
\| \| \| \| \| \|	Analysis passes do not have a good reason to depend on shader_ir.h to work on top of nodes. This splits node-related declarations to their own file and leaves the IR in shader_ir.h
*	shader: Use shared_ptr to store nodes and move initialization to file	ReinUsesLisp	2019-06-06	1	-0/+60
	Instead of having a vector of unique_ptr stored in a vector and returning star pointers to this, use shared_ptr. While changing initialization code, move it to a separate file when possible. This is a first step to allow code analysis and node generation beyond the ShaderIR class.
