2025-09-26Add SPV_NV_bindless_texture support (#8534)Lujin Wang
Treat DescriptorHandle as uint64_t instead of uint2. Implement target-specific SPIR-V emission with the bindless texture support. For OpImageTexelPointer, Image must have a type of OpTypePointer with Type OpTypeImage. Fix the issue by using [constref] in __subscript. Add a test coverage for various texture/sampler handle types. --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

2025-06-06Add command line option for separate debug info (#7178)jarcherNV
* Add command line option for separate debug info Add command line arg -separate-debug-info which, if provided, produces both a .spv and a .dbg.spv file. The .dbg.spv file contains full debug info and the .spv file has all debug info stripped out. Also add a DebugBuildIdentifier instruction to store a unique hash in both the output files, so they can be more easily matched together. A matching API is provided to allow using the Slang API to retrieve a base and debug SPIRV as well as the debug build identifier string.

2025-05-14Support the new CoopVec builtins (#7108)Jay Kwak
**NOTE: This is a breaking change for users who were using POC variant of DXC. In order to keep the compatibility, the users will have to use -capability hlsl_coopvec_poc to their command line. This PR adds a new capability "hlsl_coopvec_poc". When it is used, the HLSL for CoopVec will be emitted for the POC variant of DXC. When it is not used, the HLSL for CoopVec will be emitted for the DXC that officially supports the cooperative vector.

2024-11-05Legalize the Entry-point for WGSL (#5498)Jay Kwak
* Legalize the Entry-point for WGSL The return type of the entry-point needs to be legalized when targeting WGSL. This commit flattens the nested-structs of the return type and the input parameters of the entry-point. Most of code is copied from the legalization code for Metal. The following functions are exactly same to the implementation for Metal or almost same. - flattenInputParameters() : 136 lines - reportUnsupportedSystemAttribute() : 7 lines - ensureResultStructHasUserSemantic() : 46 lines - struct MapStructToFlatStruct : 176 lines - flattenNestedStructs() : 95 lines - maybeFlattenNestedStructs() : 42 lines - _replaceAllReturnInst() : 19 lines - _returnNonOverlappingAttributeIndex() : 16 lines - _replaceAttributeOfLayout() : 23 lines - tryConvertValue() : 41 lines - legalizeSystemValueParameters() : 11 lines They need to be refactored to reduce the duplication later. The test case, `tests/compute/assoctype-lookup.slang`, had a bug that the compute shader was trying to use the varying input/output with the user defined semantics. This commit removes the user defined semantics, because the compute shaders cannot use the user defined semantics. --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

2024-09-09Initial WGSL support (#5006)Anders Leino
* Add WGSL as a target This is required for #4807. * C-like emitter: Allow the function header emission to be overloaded WGSL-style function headers are pretty different from normal C-style headers: Normal C-style headers: ReturnType Func(...) void VoidFunc(...) WGSL-style headers: fn Func(...) -> ReturnType fn VoidFunc(...) This change allows the header style to be overloaded, in order to accomodate WGSL-style headers as required to resolve issue #4807, but retains normal C-style headers as the default implementation. [1] https://www.w3.org/TR/WGSL/#function-declaration-sec * C-like emitter: Allow emission of switch case selectors to be overloaded The C-like emitter will emit code like this: switch(a.x) { case 0: case 1: { ... } break; ... } This is not allowed in WGSL. Instead, selectors for cases that share a body must [1] be separated by commas, like this: switch(a.x) { case 0, 1: { ... } break; ... } To prepare for addressing issue #4807, this patch makes the emission of switch case selectors overloadable. [1] https://www.w3.org/TR/WGSL/#syntax-case_selectors * C-like emitter: Support WGSL-style declarations This patch helps to address issue 4807. C-like languages declare variables like this: i32 a; WGSL declares variables like this: var a : i32 The patch introduces overloads so that the forthcoming WGSL emitter can output WGSL-style declarations, which helps to resolve #4807. * C-like emitter: Support overloading of declarators Unlike C-like languages, WGSL does not support the following types at the syntax level, via declarators: - arrays - pointers - references For this reason, this patch introduces support for overloading the declarator emitter, in order to help address issue #4807. C-like languages: int a[3]; // Array-ness of type is mixed into the "declarator" WGSL: var a : array<int, 3>; // Array-ness of type is part of the... type_specifier! * C-like emitter: Allow struct declaration separator to be overridden C-like languages use ';' as a separator, and languages like e.g. WGSL use ','. This change prepares for addressing issue #4807. * C-like emitter: Allow overriding of whether pointer-like syntax is necessary Things like e.g. structured buffers map to "ptr-to-array" in WGSL, but ptr-typed expressions don't always need C-style pointer-like syntax. Therefore, make it overrideable whether or not such syntax is emitted in various cases in order to address #4807. * C-like emitter: Emit parenthesis to avoid warning about & and + precedence This helps with #4807 because WGSL compilers (e.g. Tint) treat absence of parenthesis as an error. * C-like emitter: Add hook for emitting struct field attributes WGSL requires @align attributes to specify explicit field alignment in certain cases. Thus, this patch prepares for addressing #4807. * C-like emitter: Add hook for emitting global param types Declarations of structured buffers map to global array declarations in WGSL. However, in all other cases such as when structured buffers are used in operands, their types map to *ptr*-to-array. This patch makes it possible for the WGSL back-end to say that structured buffers generally map to "ptr-to-array" types, but still have a special case of just "array" when declaring the global shader parameter. Thus, this patch helps with addressing #4807. * IR lowering: Use std140 for WGSL uniform buffers This patch just cuts out some logic that prevented std140 to be chosen for WGSL uniform buffers. Note that WGSL buffers in the uniform address space is not quite std140, but for now it's close enough to avoid compile issues. Later on, a custom layout should be created for WGSL uniform buffers. When that's done, this change will be revisited, but for now it helps to resolve #4807. * Don't emit line directives in WGSL by default WGSL does not support line directives [1]. The plan currently seems to be to instead support source-map [2]. This is part of addressing issue #4807. [1] https://github.com/gpuweb/gpuweb/issues/606 [2] https://github.com/mozilla/source-map * WGSL IR legalization: Map SV's The implementation closely follows the cooresponding one for Metal. Supported: - DispatchThreadID - GroupID - GroupThreadID - GroupThreadID Unsupported: - GSInstanceID This is not complete, but it helps to address #4807. * WGSL emitter: Add support for basic language constructs A lot of the basics are added in order to generate correct WGSL code for basic Slang language constructs. This addresses issue #4807. This adds support for at least the following: - statments - if statements - ternary operator - while statement - for statements - variable declarations - switch statements - Note: Slang may emit non-constant case expressions, see issue 4834 - literals - integer literals - u?int[16|32|64]_t - float and half literals - bool literals - vector literals and splatting (e.g 1.xxx) - function definitions - assignments - +=, *=, /= - array assignments - vector assignments/updates - swizzles of other vectors - from matrix rows ('m[i]' notation) - from matrix cols (using swizzle notation, e.g 'm._11_12_13') - matrix assignments/updates - to rows ('m[i]' notation) - to cols (using swizzle notation, e.g 'm._11_12_13') - declarations - arrays [1] https://www.w3.org/TR/WGSL/#syntax-switch_body * Add some WGSL capabilities This patch registers some WGSL capabilities required to pass many of the initial compute shader compile tests. Many capabilities still remain to be added -- this is just an initial set to help resolve issue #4807. - asint - min and max - cos and sin - all and any * WGSL and C-like emitters: Add hack to bitcast case expression In WGSL, the switch condition and case types must match. https://www.w3.org/TR/WGSL/#switch-statement Slang currently allows these types to mismatch, as pointed out in #4921. Issue #4921 should eventually be addressed in the front-end by a patch like [1]. However, at the moment that would break Falcor tests. Thus, this patch temporarily works around the issue in the WGSL emitter only in order to help resolve #4807. In the future, the Falcor tests should be fixed, this patch should be dropped and [1] should be merged instead. [1] a32156ef52f43b8503b2c77f2f1d51220ab9bdea

2024-08-12Warn when inout parameter is never written (#4777)venkataram-nv
Addresses #4698 as one approach to diagnose the potential problem. Emit warnings when a user marks a parameter as `inout` but never writes to it in the function. A new intrinsic function `unmodified(out T)` has been added to explicitly indicate that an `inout` variable will not be modified in the function. This is only one way to address the specific validation error in #4698. In general it seems that DXC does some more extensive checks on actual struct fields (as opposed to observing arbitrary struct writes), so that will be the next step.

2024-07-10Implement non member function atomic texture support (#4544)ArielG-NV
* Implement non member function atomic texture support texture_buffer and texture1d Fixes: #4538 Related to: #4291, fixes `tests/compute/atomics-buffer.slang` Texture objects cannot use `__getMetalAtomicRef` to cast objects into atomic value type. [Texture objects mandate use of member functions](https://developer.apple.com/metal/Metal-Shading-Language-Specification.pdf#Texture%20Functions). The implementation is as follows: * We can detect texture object usage through checking for an `IRImageSubscript` Operation. `__isTextureAccess()` was added to evaluate if we have an `IRImageSubscript` operation at compile time (before `static_assert`). `__isTextureAccess()` only checks if we are targeting Metal. * We have all parameter data needed to call a texture atomic function embedded inside `IRImageSubscript`. `__extractTextureFromTextureAccess()` and `__extractCoordFromTextureAccess()` was added to extract this data for use with Metal atomics. Note: * Metal documentation has various incorrect details (function names) * Since we currently hardcode metal versions for compiling, the Metal compiler version was changed to target `Metal 3.1` (`slang-gcc-compiler-util.cpp`) * textures do not permit atomic float operations * add fallthrough attribute + fix bug with 'exchange instead of xor' + fix warning bug * incorrect function name fix * missing filecheck * disable atomics-buffer.slang compute test since GFX issue causing it to fail * Array support for metal interlockedAtomic and proper verification of texture with interlockedAtomic functions * Array support for metal interlockedAtomic * proper verification of texture with interlockedAtomic functions note: had to seperate many functions to allow forceInlining to run * missing getOperand(0) * push atomic fix for metal * fix atomic syntax for metal and hlsl emitting extra brackets (breaks tests) * test changes and meta changes 1. max is 8 rw textures with metal because Metal has this limit. Split up tests to not hit this limit 2. added back `[0]`...,`T` to test since this legalizes metal atomic intrinsic * macro'ify some of the atomic code 1. addresses review 2. makes code easier to modify in the future (rather than sifting through 1000 lines we can just look at ~10-30 * fix test 'check' * missing float support due to macro * add functions macro generates, `InternalAtomicOperationInfo` --------- Co-authored-by: Yong He <yonghe@outlook.com>
2024-06-28Implement HLSL resource bindings and default type `float4` to ↵ArielG-NV
`SubpassInput<T>` (#4462) * Add case to `emitVectorReshape` for `vector<>` type, `scalar` value 1. Add new case 2. Add test * fix warning * fix warning * Implement HLSL resource bindings and default type `float4` to `SubpassInput<T>` fixes: #4440 1. Removed GLSLInputAttachmentIndexLayout modifier and the somewhat 'hacky' binding model 'Input Attachment' previously relied upon. This was changed to work with the slang-type-layout rules system. This change allows Slang automatic bindings, HLSL bindings, GLSL bindings, and translation of GLSL to and from HLSL bindings to work. 2. Added default argument `float4` to SubpassInput<T>. 3. Merged glsl.meta and hlsl.meta SubpassInput logic. * fix InputAttachment attribute checks fix InputAttachment attribute checks for HLSL and GLSL syntax * remove unused var * validate attribute correctly Attributes do not have type information. We must check the type expression to validate attribute usage. * remove hacky validation type based validation before types are fully resolved is quite hacky and unstable to changes and wrapped types * fix warning * remove redundant `!= nullptr` * remove extra `!= nullptr` * fix some warnings/errors * subpass capability to limit to dxc & remove default values in some functions * revert logic to previous logic revert logic to return if we have a binding regardless of if a VarDecl is given the binding
2024-06-25Support atomic intrinsics for Metal (#4473)Jay Kwak
* Support atomic intrinsics for Metal This commit adds a support for the atomic intrinsics in Metal. The atomic member functions for buffers is not implemented yet. Metal requires the first argument for the atomic functions to be an atomic data type. This implementation rely on the fact that we can do a C-style type casting from a regular data type to an atomic data type.
