Add proper handling of input topologies in the Geometry stage for all three
shader backends (GLASM, GLSL, SPIRV). This implementation uses a lookup table
approach to determine vertex counts based on input topology type (Points,
Lines, LinesAdjacency, Triangles, TrianglesAdjacency) and shifts the vertex
count by 16 bits as required by the invocation info format.
Additional changes:
- Fixed TessellationControl and TessellationEval stages to properly break
after emitting code
- Added proper header include for runtime_info.h in GLASM backend
- Improved code documentation with clear commenting patterns
This change ensures accurate geometry shader behavior across all backends,
improving compatibility with games that rely on proper vertex count reporting.

This crashes their shader compiler for some reason.
|
|
These formats are unsupported by mobile GPUs so they need to be emulated in shaders instead.

ImageGatherSubpixelOffset
Should be more efficient and better readable
|
|
On AMD a subpixel offset of 1/512 of the texel size is applied to the texture coordinates at a ImageGather call to ensure the rounding at the texel centers is done the same way as in Maxwell or other Nvidia architectures.
See https://www.reedbeta.com/blog/texture-gathers-and-coordinate-precision/ for more details why this might be necessary.
This should fix shadow artifacts at object edges in Zelda: Breath of the Wild (#9957, #6956).

shader_recompiler: Remove S32 IR type
|
|
|
|
The frontend IR opcodes do not distinguish between signed and unsigned integer types.
Fixes broken shaders when IR validation/graphics debugging is enabled for shaders that used BitCastS32F32

|
|
The existing implementation only supports 64 invoc-per-subgroup GPUs, and misbehaves on adreno when invocations need to be split into 4 emulated subgroups.
|
|
|
|
Adreno drivers will crash compiling geometry shaders if the input position is not wrapped in a gl_in struct.
