Instead of storing all block width, height and depths in their shifted
form:
block_width = 1U << block_shift;
Store them like they are provided by the emulated hardware (their
block_shift form). This way we can avoid doing the costly
Common::AlignUp operation to align texture sizes and drop CPU integer
divisions with bitwise logic (defined in Common::AlignBits).
Due to our current infrastructure, it is possible for a mipmap to be set
on as a render target before a texception of that mipmap's superset be
set afterwards. This is problematic as we rely on texture views to set
up texceptions and protecting render targets targets for 3D texture
rendering.
One simple solution is to configure framebuffers after texture setup but
this brings other problems. This solution, forces a reconfiguration of
the framebuffers after such event happens.
These source files have been unused for the entire lifecycle of the
project. They're a hold-over from Citra and only add to the build time
of the project, so they can be removed.
There's also likely no way this would ever work in yuzu in its current
form without revamping quite a bit of it, given how different the GPU on
the Switch is compared to the 3DS.
This test is intended to be invalid GLSL, but it was being invalid in
two points instead of one. The intention is to use a non-immediate
parameter in a textureOffset like function.
The problem is that this shader was being compiled as a separable
shader object and the text was writting to gl_Position without a
redeclaration, being invalid GLSL.
Address that issue by using a user-defined output attribute.
Hardware testing revealed that SSY and PBK push to a different stack,
allowing code like this:
SSY label1;
PBK label2;
SYNC;
label1: PBK;
label2: EXIT;
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
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.
