* shader_ir: Implement VOTEReinUsesLisp2019-08-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* video_core/shader/decode: Prevent sign-conversion warningsLioncash2019-07-191-2/+2
| | | | Makes it explicit that the conversions here are intentional.
* shader_ir: std::move Node instance where applicableLioncash2019-07-171-4/+4
| | | | | | | | | These are std::shared_ptr instances underneath the hood, which means copying them isn't as cheap as a regular pointer. Particularly so on weakly-ordered systems. This avoids atomic reference count increments and decrements where they aren't necessary for the core set of operations.

* shader: Use shared_ptr to store nodes and move initialization to fileReinUsesLisp2019-06-061-0/+1
| | | | | | | | | 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.

* shader_ir: Pass decoded nodes as a whole instead of per basic blocksReinUsesLisp2019-02-031-6/+9
| | | | | | | | | Some games call LDG at the top of a basic block, making the tracking heuristic to fail. This commit lets the heuristic the decoded nodes as a whole instead of per basic blocks. This may lead to some false positives but allows it the heuristic to track cases it previously couldn't.
* shader/decode: Avoid a pessimizing std::move within DecodeRange()Lioncash2019-01-281-1/+1
| | | | | | std::moveing a local variable in a return statement has the potential to prevent copy elision from occurring, so this can just be converted into a regular return.
