* Enable hlsl-intrinsic/byte-address-buffer/byte-address-struct * Set byte address buffer legalization options for WGSL
2024-11-21Refresh of disabled WGPU tests (#5614)Anders Leino
Some tests are now passing and are enabled. Other tests are still failing, but are given comments categorizing the failures. Tests in the 'Not supported in WGSL' category are also removed from the expected failures list. (Though they are still kept disabled for WebGPU, of course.) This closes #5519.

2024-11-05Fixing the wrong implementation of some math intrinsic (#5491)kaizhangNV
* Fixing the wrong implementation of some math intrinsic Close the issue #5282 The root cause of the issue is that log10 is not supported in wgsl. So add the implementation. Also ldexp in wgsl doesn't support float type exponent, so fix the implementation of the intrinsic. * re-enable the tests

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.
2024-07-18Metal: `Interlocked` (atomic) member function support for buffers (#4655)ArielG-NV
* Metal: `Interlocked` (atomic) member function support for buffers fixes: #4654 fixes: #4481 1. Add `Interlocked` (atomic) member function support for buffers to Metal 2. Fix `__getEquivalentStructuredBuffer` so it works with CPP/Metal targets * add `CompareStore` support * legalize RWByteAddressBuffer to fully replace StructuredBuffer * destroy replaced byte-addr buffer * cleanup as per review and add comment to explain why certain code exists * fix flow of byte-address-buffer replacement * toggle on option to translate byteAddrBuffer to StructuredBuffer * cleanup unused buffers * add treatGetEquivalentStructuredBufferAsGetThis flag to treat getEquivStructuredBuffer as a byteAddressBuffer * comment to explain `treatGetEquivalentStructuredBufferAsGetThis` --------- Co-authored-by: Yong He <yonghe@outlook.com>
2024-07-18Update spirv-header and spirv-tools to Jun/2024 (#4679)Jay Kwak
The following external directories are updated. It is to use a new SPIRV keyword, "OpExtInstWithForwardRefs". Related to #4304 external/spirv-header: > commit 2acb319af38d43be3ea76bfabf3998e5281d8d12 > Author: Kévin Petit kevin.petit@arm.com > Date: Wed Jun 12 16:41:14 2024 +0100 > SPV_ARM_cooperative_matrix_layouts (#433) external/spirv-tools: > commit ce46482db7ab3ea9c52fce832d27ca40b14f8e87 > Author: Nathan Gauër brioche@google.com > Date: Thu Jun 6 12:17:51 2024 +0200 > Add KHR suffix to OpExtInstWithForwardRef opcode. (#5704) > The KHR suffix was missing from the published SPIR-V extension. > This is now fixed, but requires some patches in SPIRV-Tools. external/spirv-tools-generated: This is generated from spirv-tools
2024-07-18Fix bug with uninititialized warnings in nested scopes (#4677)venkataram-nv
Previously the warning system ignores undefined variables in nested scopes (blocks in IR).
2024-07-16SCCP instead of CFG since SCCP removes code of unused branches, not CFG (#4640)ArielG-NV
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>
2024-07-10Support status argument for GatherXXX (#4490)Jay Kwak

2024-06-28Implement CheckAccessFullyMapped (#4509)Jay Kwak
* Implement CheckAccessFullyMapped Closes #4438 Closes #4445 Closes #1712 Related to #4495 This commit implements "CheckAccessFullyMapped()" for HLSL target. All of other "status" variants for Sample/Load are limited to HLSL by the capability system, because they not properly implemented yet.
2024-06-27Extend `countbits` intrinsic for vector types (#4499)venkataram-nv
* Extend `countbits` intrinsic for vector types This commit implements the overloading function for `countbits` function. Because HLSL has following overloadings, ``` uint count_bits(uint value); uint2 count_bits(uint2 value); uint3 count_bits(uint3 value); uint4 count_bits(uint4 value); ``` https://learn.microsoft.com/en-us/windows/win32/direct3dhlsl/countbits
2024-06-27Implement `uint2` variant of `asdouble` intrinsic (#4488)venkataram-nv
* Implement asdouble2 intrinsic and tests Fixes #4437 Adds a new asdouble2 intrinsic for all platforms except Metal. Extends the test for asdouble to test asdouble2 as well.
2024-06-25Add intrinsic for `IsHelperLane()` in HLSL (#4471)venkataram-nv
Add InHelperLane() intrinsic for HLSL, GLSL, Metal and Spirv.
2024-06-24Added float2x2 cast to float4 (and vise versa) (#4432)ArielG-NV
* added float4x4<->float4 casting (and related) Note: not adding `matrix<1,N>` and `matrix<N,1>` translations since this will bloat stdlib with many expensive to process `extension` operations. `matrix<N,1>` is already planned to be treated as vectors (which should solve this problem by proxy). * address review * explicit cast mat to vec
2024-06-14Improve Direct SPIRV Backend Test Coverage (#4396)ArielG-NV
'raytracing' and 'texture-footprint' tests fixed texture-footprint bug changed when we emit raytracing/rayquery extensions with glsl backend (to reduce incorrect extension emitting)
