This commit corrects the argument ordering in textureGatherOffset. | |||||
2019-10-30 | shader/node: Unpack bindless texture encoding | ReinUsesLisp | 1 | -6/+6 | |
Bindless textures were using u64 to pack the buffer and offset from where they come from. Drop this in favor of separated entries in the struct. Remove the usage of std::set in favor of std::list (it's not std::vector to avoid reference invalidations) for samplers and images. | |||||
2019-10-25 | gl_shader_decompiler: Move entries to a separate function | ReinUsesLisp | 1 | -35/+35 | |
2019-10-25 | Shader_IR: Implement Fast BRX and allow multi-branches in the CFG. | Fernando Sahmkow | 1 | -0/+5 | |
2019-10-16 | gl_shader_decompiler: Resolve fallthrough within ExprDecompiler's ExprCondCode operator() | Lioncash | 1 | -0/+3 | |
This would previously result in NeverExecute and UnusedIndex being treated as regular predicates. | |||||
2019-10-16 | gl_shader_decompiler: Make ExprDecompiler's GetResult() a const member function | Lioncash | 1 | -1/+1 | |
This is only ever used to read, but not write, the resulting string, so we can enforce this by making it a const member function. | |||||
2019-10-16 | gl_shader_decompiler: Use a std::string_view with GetDeclarationWithSuffix() | Lioncash | 1 | -1/+1 | |
This allows the function to be completely non-allocating for inputs of all sizes (i.e. there's no heap cost for an input to convert to a std::string_view). | |||||
2019-10-16 | gl_shader_decompiler: Fold flow_var constant into GetFlowVariable() | Lioncash | 1 | -3/+1 | |
This is only ever used within this function, so we can narrow it's scope down. | |||||
2019-10-16 | gl_shader_decompiler: Mark ASTDecompiler/ExprDecompiler parameters as const references where applicable | Lioncash | 1 | -21/+21 | |
These member functions don't actually modify the input parameter, so we can make this explicit with the use of const. | |||||
2019-10-16 | gl_shader_decompiler: Pass by reference to GenerateTextureArgument() | Lioncash | 1 | -2/+2 | |
Avoids an unnecessary atomic reference count increment and decrement. | |||||
2019-10-16 | gl_shader_decompiler: Use std::holds_alternative within GenerateTexture() | Lioncash | 1 | -1/+1 | |
This only ever queries if the type exists within the variant, but doesn't actually do anything with the return value. We can just use std::holds_alternative for this use case. | |||||
2019-10-16 | gl_shader_decompiler: Avoid unnecessary copies of MetaImage | Lioncash | 1 | -4/+4 | |
MetaImage contains a std::vector, so copying here could result in unnecessary reallocations. Given the operation lives throughout the entire scope, this is safe to do. | |||||

2019-09-21 | gl_shader_decompiler: Use uint for images and fix SUATOM | ReinUsesLisp | 1 | -97/+35 | |
In the process remove implementation of SUATOM.MIN and SUATOM.MAX as these require a distinction between U32 and S32. These have to be implemented with imageCompSwap loop. | |||||

2019-09-04 | gl_shader_decompiler: Rework GLSL decompiler type system | ReinUsesLisp | 1 | -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. | |||||
2019-08-21 | shader_ir: Implement VOTE | ReinUsesLisp | 1 | -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. | |||||
2019-07-20 | Shader_Ir: Implement F16 Variants of F2F, F2I, I2F. | Fernando Sahmkow | 1 | -0/+18 | |
This commit takes care of implementing the F16 Variants of the conversion instructions and makes sure conversions are done. | |||||

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

2019-07-09 | shader_ir: Implement BRX & BRA.CC | Fernando Sahmkow | 1 | -0/+9 | |
2019-07-08 | gl_shader_decompiler: Implement gl_ViewportIndex and gl_Layer in vertex shaders | ReinUsesLisp | 1 | -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. | |||||

2019-06-07 | shader: Split SSY and PBK stack | ReinUsesLisp | 1 | -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; | |||||
2019-06-06 | shader: Use shared_ptr to store nodes and move initialization to file | ReinUsesLisp | 1 | -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. | |||||
2019-06-03 | gl_shader_decompiler: Remove guest "position" varying | ReinUsesLisp | 1 | -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. | |||||
2019-05-30 | gl_rasterizer: Move alpha testing to the OpenGL pipeline | ReinUsesLisp | 1 | -19/+1 | |
Removes the alpha testing code from each fragment shader invocation. | |||||
2019-05-24 | gl_shader_decompiler: Use an if based cbuf indexing for broken drivers | ReinUsesLisp | 1 | -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; ``` | |||||
2019-05-21 | renderer_opengl/gl_shader_decompiler: Remove redundant name specification in format string | Lioncash | 1 | -1/+1 | |
This accidentally slipped through a rebase. | |||||
2019-05-20 | shader: Implement S2R Tid{XYZ} and CtaId{XYZ} | ReinUsesLisp | 1 | -0/+16 | |
2019-05-20 | gl_shader_decompiler: Make GetSwizzle constexpr | ReinUsesLisp | 1 | -7/+7 | |
2019-05-20 | gl_shader_decompiler: Tidy up minor remaining cases of unnecessary std::string concatenation | Lioncash | 1 | -21/+20 | |
2019-05-20 | gl_shader_decompiler: Replace individual overloads with the fmt-based one | Lioncash | 1 | -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. | |||||
2019-05-20 | gl_shader_decompiler: Utilize fmt overload of AddLine() where applicable | Lioncash | 1 | -136/+152 | |
2019-05-19 | gl_shader_decompiler: Add AddLine() overload that forwards to fmt | Lioncash | 1 | -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. | |||||
2019-05-10 | video_core/renderer_opengl/gl_shader_decompiler: Remove unused Composite() function | Lioncash | 1 | -11/+0 | |
This isn't used at all, so it can be removed. | |||||

2019-05-03 | shader: Remove unused AbufNode Ipa mode | ReinUsesLisp | 1 | -2/+1 | |
2019-04-16 | shader_ir/decode: Fix half float pre-operations and remove MetaHalfArithmetic | ReinUsesLisp | 1 | -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. | |||||
2019-04-16 | gl_shader_decompiler: Fix MrgH0 decompilation | ReinUsesLisp | 1 | -2/+2 | |
GLSL decompilation for HMergeH0 was wrong. This addresses that issue. | |||||

2019-04-10 | Remove bounding in LD_C | Fernando Sahmkow | 1 | -2/+1 | |
2019-04-05 | gl_shader_decompiler: Rename GenerateTemporal() to GenerateTemporary() | Lioncash | 1 | -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. | |||||
2019-04-05 | gl_shader_decompiler: Fix TXQ types | ReinUsesLisp | 1 | -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. | |||||

2019-02-07 | shader_ir: Remove F4 prefix to texture operations | ReinUsesLisp | 1 | -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. | |||||
2019-02-07 | shader_ir: Clean texture management code | ReinUsesLisp | 1 | -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. | |||||

It's not always used as a basic block. Rename it for consistency. | |||||
2019-01-30 | shader_ir: Unify constant buffer offset values | ReinUsesLisp | 1 | -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. | |||||
