scribam db926ee671 rsx: Apply Clang-Tidy fix "performance-unnecessary-value-param" 2019-06-12 15:11:52 +03:00
kd-11 3cbccdd760 rsx: Fragment shader decompiler cleanup 
TODO: Investigate the _s input modifier behaviour further, in case it can avoid generating zeroes from a MAD instruction.
x = MAD(+ve, -ve, -ve) with _s input modifier in BFBC expects result to be Non-zero

kd-11 463b1b220d rsx: Improve accuracy of shadow compare Ops when non-integer depth formats are used 
- The fixed-point D24S8 format does special Z clamping during compare which matches PS3 behaviour
- D32S8 is a floating point format and comparison with Dref > 1 always fails causing black edges/borders

kd-11 06a85f00d1 rsx: Shader decompiler cleanup and improvements 
- Improve support for float16_t by minimizing mixed inputs to functions
(ambiguous overloads)
- Minimize amount of downcasts in code by using opcode flags
- Re-enable float16_t support for vulkan
 2019-04-25 16:23:05 +03:00
kd-11 a668560c68 rsx: Use native half float types if available 
- Emulating f16 with f32 is not ideal and requires a lot of value clamping
- Using native data type can significantly improve performance and accuracy
- With openGL, check for the compatible extensions NV_gpu_shader5 and
AMD_gpu_shader_half_float
- With Vulkan, enable this functionality in the deviceFeatures if
applicable. (VK_KHR_shader_float16_int8 extension)
- Temporarily disable hw fp16 for vulkan

kd-11 736415fcd9 rsx/fp: Detect broken/NOP shaders automatically 
- Do not compile body if the shader is of no consequence, leave as a passthrough shader

kd-11 dea5193fd7 rsx: Fix FP temp register count 2018-09-03 21:39:18 +03:00
scribam 04ad49de4d typos 2018-05-14 21:14:39 +04:00
kd-11 68b3229756 rsx/fp: Improve rgister component gather detection 
- Also avoids clobbering register data by keeping gathered bits in a temp var
 2018-03-13 18:55:03 +03:00
kd-11 a64bea1286 rsx/fp: Discard shaders with undefined (non-existent) writes. On nvidia+vulkan, undefined writes autofill with blue color 2018-02-16 16:14:54 +03:00
kd-11 33bcdd476c glsl/fp/vp: Avoid shader clutter 
- Do not add unused subroutines in shaders unless necessary
-- makes shaders easier to read and disassembled spir-v has less clutter
- glsl: Replace switch block with lookup table

lewmpk d64e79bd9f fix clang warning: logical-op-parentheses 2017-12-31 22:08:17 +03:00
kd-11 f7c52d3bb7 rsx/fp: Implement TEXBEM (untested) 2017-12-18 10:45:37 +03:00
kd-11 cdd4fd9867 rsx/fp: Explicitly insert global functions. 
- Functions such as pack/unpack ops must exist before the shared gather functions are declared
 2017-12-04 18:22:18 +03:00
kd-11 fe9090bd39 rsx/fp: Implement register gather (only for UP(X) instructions) 
- Workaround for temp register aliasing between H and R variants
- TODO: Implement temp regs as 128 bit-blocks with r/w as pack/unpack
 2017-12-01 21:00:50 +03:00
kd-11 a8c0dd649e rsx/fp: RE work on precision modifier bits 
- Testing DS2 has revealed clamping bits in SRC1 that were not respected and left negative values reaching the framebuffer
