2021-07-22shader: Remove old shader managementReinUsesLisp
2020-12-07video_core: Remove unnecessary enum class casting in logging messagesLioncash
fmt now automatically prints the numeric value of an enum class member by default, so we don't need to use casts any more. Reduces the line noise a bit.
2019-12-09shader: Keep track of shaders using warp instructionsReinUsesLisp
2019-11-07shader_ir/warp: Implement FSWZADDReinUsesLisp
2019-11-07gl_shader_decompiler: Reimplement shuffles with platform agnostic intrinsicsReinUsesLisp
2019-10-23video_core/shader: Resolve instances of variable shadowingLioncash
Silences a few -Wshadow warnings.

2019-08-21shader_ir: Implement VOTEReinUsesLisp
Implement VOTE using Nvidia's intrinsics. Documentation about these can be found here https://developer.nvidia.com/reading-between-threads-shader-intrinsics Instead of using portable ARB instructions I opted to use Nvidia intrinsics because these are the closest we have to how Tegra X1 hardware renders. To stub VOTE on non-Nvidia drivers (including nouveau) this commit simulates a GPU with a warp size of one, returning what is meaningful for the instruction being emulated: * anyThreadNV(value) -> value * allThreadsNV(value) -> value * allThreadsEqualNV(value) -> true ballotARB, also known as "uint64_t(activeThreadsNV())", emits VOTE.ANY Rd, PT, PT; on nouveau's compiler. This doesn't match exactly to Nvidia's code VOTE.ALL Rd, PT, PT; Which is emulated with activeThreadsNV() by this commit. In theory this shouldn't really matter since .ANY, .ALL and .EQ affect the predicates (set to PT on those cases) and not the registers.
