2019-08-27float_set_predicate: Add missing negation bit for the second operandReinUsesLisp
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.

Downgrade and suppress a series of GPU asserts and debug messages.

2019-07-20Shader_Ir: Implement F16 Variants of F2F, F2I, I2F.Fernando Sahmkow
This commit takes care of implementing the F16 Variants of the conversion instructions and makes sure conversions are done.

2019-07-18video_core/control_flow: Provide operator!= for types with operator==Lioncash
Provides operational symmetry for the respective structures.
2019-07-18video_core/control_flow: Prevent sign conversion in TryGetBlock()Lioncash
The return value is a u32, not an s32, so this would result in an implicit signedness conversion.
2019-07-18video_core/control_flow: Remove unnecessary BlockStack copy constructorLioncash
This is the default behavior of the copy constructor, so it doesn't need to be specified. While we're at it we can make the other non-default constructor explicit.
2019-07-18video_core/control_flow: Use std::move where applicableLioncash
Results in less work being done where avoidable.
2019-07-18video_core/control_flow: Use the prefix variant of operator++ for iteratorsLioncash
Same thing, but potentially allows a standard library implementation to pick a more efficient codepath.
2019-07-18video_core/control_flow: Use empty() member function for checking emptinessLioncash
It's what it's there for.
2019-07-18video_core: Resolve -Wreorder warningsLioncash
Ensures that the constructor members are always initialized in the order that they're declared in.
2019-07-18video_core/control_flow: Make program_size for ScanFlow() a std::size_tLioncash
Prevents a truncation warning from occurring with MSVC. Also the internal data structures already treat it as a size_t, so this is just a discrepancy in the interface.
2019-07-18video_core/control_flow: Place all internally linked types/functions within ↵Lioncash
an anonymous namespace Previously, quite a few functions were being linked with external linkage.
2019-07-18video_core/shader/decode: Prevent sign-conversion warningsLioncash
Makes it explicit that the conversions here are intentional.

2019-07-18Shader_Ir: Downgrade precision and rounding asserts to debug asserts.Fernando Sahmkow
This commit reduces the sevirity of asserts for FP precision and rounding as this are well known and have little to no consequences in gpu's accuracy.

shader/decode/other: Correct branch indirect argument within BRA handling
2019-07-16shader_ir: std::move Node instance where applicableLioncash
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.
2019-07-16shader_ir: Rename Get/SetTemporal to Get/SetTemporaryLioncash
This is more accurate in terms of describing what the functions are actually doing. Temporal relates to time, not the setting of a temporary itself.
2019-07-16shader_ir: Remove unused includesLioncash
Removes unnecessary header dependencies.

2019-07-16shader/decode/other: Correct branch indirect argument within BRA handlingLioncash
This appears to have been a copy/paste error introduced within 8a6fc529a968e007f01464abadd32f9b5eb0a26c

2019-07-14shader: Allow tracking of indirect buffers without variable offsetReinUsesLisp
While changing this code, simplify tracking code to allow returning the base address node, this way callers don't have to manually rebuild it on each invocation.
