2019-09-04gl_shader_decompiler: Rework GLSL decompiler type systemReinUsesLisp1-416/+505
GLSL decompiler type system was broken. We converted all return values to float except for some cases where returning we couldn't and implicitly broke the rule of returning floats (e.g. for bools or bool pairs). Instead of doing this introduce class Expression that knows what type a return value has and when a consumer wants to use the string it asks for it with a required type, emitting a runtime error if types are incompatible. This has the disadvantage that there's more C++ code, but we can emit better GLSL code that's easier to read.
2019-08-21shader_ir: Implement VOTEReinUsesLisp1-0/+47
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.
2019-07-20Shader_Ir: Implement F16 Variants of F2F, F2I, I2F.Fernando Sahmkow1-0/+18
This commit takes care of implementing the F16 Variants of the conversion instructions and makes sure conversions are done.

2019-07-18gl_shader_decompiler: Rename bufferImage to imageBufferReinUsesLisp1-1/+1
The online OpenGL documentation is wrong. The type definition is imageBuffer.

2019-07-08gl_shader_decompiler: Implement gl_ViewportIndex and gl_Layer in vertex shadersReinUsesLisp1-29/+75
This commit implements gl_ViewportIndex and gl_Layer in vertex and geometry shaders. In the case it's used in a vertex shader, it requires ARB_shader_viewport_layer_array. This extension is available on AMD and Nvidia devices (mesa and proprietary drivers), but not available on Intel on any platform. At the moment of writing this description I don't know if this is a hardware limitation or a driver limitation. In the case that ARB_shader_viewport_layer_array is not available, writes to these registers on a vertex shader are ignored, with the appropriate logging.

2019-06-21gl_shader_decompiler: Allow 1D textures to be texture buffersReinUsesLisp1-4/+38
2019-06-07shader: Split SSY and PBK stackReinUsesLisp1-4/+27
Hardware testing revealed that SSY and PBK push to a different stack, allowing code like this: SSY label1; PBK label2; SYNC; label1: PBK; label2: EXIT;
2019-06-06shader: Use shared_ptr to store nodes and move initialization to fileReinUsesLisp1-31/+31
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.
2019-06-03gl_shader_decompiler: Remove guest "position" varyingReinUsesLisp1-19/+19
"position" was being written but not read anywhere besides geometry shaders, where it had the same value as gl_Position. This commit replaces "position" with gl_Position, reducing the complexity of our code and the emitted GLSL code.
2019-05-30gl_rasterizer: Move alpha testing to the OpenGL pipelineReinUsesLisp1-19/+1
Removes the alpha testing code from each fragment shader invocation.
2019-05-24gl_shader_decompiler: Use an if based cbuf indexing for broken driversReinUsesLisp1-3/+20
The following code is broken on AMD's proprietary GLSL compiler: ```glsl uint idx = ...; vec4 values = ...; float some_value = values[idx & 3]; ``` It index the wrong components, to fix this the following pessimized code is emitted when that bug is present: ```glsl uint idx = ...; vec4 values = ...; float some_value; if ((idx & 3) == 0) some_value = values.x; if ((idx & 3) == 1) some_value = values.y; if ((idx & 3) == 2) some_value = values.z; if ((idx & 3) == 3) some_value = values.w; ```
2019-05-21renderer_opengl/gl_shader_decompiler: Remove redundant name specification in format stringLioncash1-1/+1
This accidentally slipped through a rebase.
2019-05-20shader: Implement S2R Tid{XYZ} and CtaId{XYZ}ReinUsesLisp1-0/+16
2019-05-20gl_shader_decompiler: Make GetSwizzle constexprReinUsesLisp1-7/+7
2019-05-20gl_shader_decompiler: Tidy up minor remaining cases of unnecessary std::string concatenationLioncash1-21/+20
2019-05-20gl_shader_decompiler: Replace individual overloads with the fmt-based oneLioncash1-28/+16
Gets rid of the need to special-case brace handling depending on the overload used, and makes it consistent across the board with how fmt handles them. Strings with compile-time deducible strings are directly forwarded to std::string's constructor, so we don't need to worry about the performance difference here, as it'll be identical.
2019-05-20gl_shader_decompiler: Utilize fmt overload of AddLine() where applicableLioncash1-136/+152
2019-05-19gl_shader_decompiler: Add AddLine() overload that forwards to fmtLioncash1-0/+11
In a lot of places throughout the decompiler, string concatenation via operator+ is used quite heavily. This is usually fine, when not heavily used, but when used extensively, can be a problem. operator+ creates an entirely new heap allocated temporary string and given we perform expressions like: std::string thing = a + b + c + d; this ends up with a lot of unnecessary temporary strings being created and discarded, which kind of thrashes the heap more than we need to. Given we utilize fmt in some AddLine calls, we can make this a part of the ShaderWriter's API. We can make an overload that simply acts as a passthrough to fmt. This way, whenever things need to be appended to a string, the operation can be done via a single string formatting operation instead of discarding numerous temporary strings. This also has the benefit of making the strings themselves look nicer and makes it easier to spot errors in them.
2019-05-10video_core/renderer_opengl/gl_shader_decompiler: Remove unused Composite() functionLioncash1-11/+0
This isn't used at all, so it can be removed.

2019-05-03shader: Remove unused AbufNode Ipa modeReinUsesLisp1-2/+1
2019-04-16shader_ir/decode: Fix half float pre-operations and remove MetaHalfArithmeticReinUsesLisp1-28/+23
Operations done before the main half float operation (like HAdd) were managing a packed value instead of the unpacked one. Adding an unpacked operation allows us to drop the per-operand MetaHalfArithmetic entry, simplifying the code overall.
2019-04-16gl_shader_decompiler: Fix MrgH0 decompilationReinUsesLisp1-2/+2
GLSL decompilation for HMergeH0 was wrong. This addresses that issue.
2019-04-16shader_ir/decode: Implement half float saturationReinUsesLisp1-4/+11

2019-04-05gl_shader_decompiler: Rename GenerateTemporal() to GenerateTemporary()Lioncash1-12/+12
Temporal generally indicates a relation to time, but this is just creating a temporary, so this isn't really an accurate name for what the function is actually doing.
2019-04-05gl_shader_decompiler: Fix TXQ typesReinUsesLisp1-2/+3
TXQ returns integer types. Shaders usually do: R0 = TXQ(); // => int R0 = static_cast<float>(R0); If we don't treat it as an integer, it will cast a binary float value as float - resulting in a corrupted number.

2019-02-07shader_ir: Remove F4 prefix to texture operationsReinUsesLisp1-12/+12
This was originally included because texture operations returned a vec4. These operations now return a single float and the F4 prefix doesn't mean anything.
2019-02-07shader_ir: Clean texture management codeReinUsesLisp1-32/+41
Previous code relied on GLSL parameter order (something that's always ill-formed on an IR design). This approach passes spatial coordiantes through operation nodes and array and depth compare values in the the texture metadata. It still contains an "extra" vector containing generic nodes for bias and component index (for example) which is still a bit ill-formed but it should be better than the previous approach.

2019-02-03shader_ir: Rename BasicBlock to NodeBlockReinUsesLisp1-3/+3
It's not always used as a basic block. Rename it for consistency.
2019-01-30shader_ir: Unify constant buffer offset valuesReinUsesLisp1-2/+3
Constant buffer values on the shader IR were using different offsets if the access direct or indirect. cbuf34 has a non-multiplied offset while cbuf36 does. On shader decoding this commit multiplies it by four on cbuf34 queries.
