2024-11-14Insert some casts for WGSL texture attribute queries (#5560)Anders Leino
* Add new texture sampling test for WebGPU There are no 1d array textures in WGSL, so add texture-sampling-no-1d-arrays.slang based on texture-sampling.slang, but without 1d texture arrays.

2024-11-13Correct include dir for libslang (#5539)Ellie Hermaszewska
This stops adding the repo root to the include path for anything linking with slang. This enabled a bunch of convenient includes, but might lead to confusing behavior for anyone including slang. Not to mention differences including it from an install vs source. Co-authored-by: Yong He <yonghe@outlook.com>

2024-11-12Fix two specialization bugs (#5540)Anders Leino
* Fix two specialization bugs The first bug was introduced in b2ca2d5a4efeae807d3c3f48f60235e47413b559 and ran some code at scope exit that dereferenced a nullptr context. The second bug was introduced in bea1394ad35680940a0b69b9c67efc43764cc194 and would cause the wrong mangled name to be used during specialization.

2024-11-08Fix EHa flag compiler filtering (#5524)cheneym2
The previous attempt to enable Structured Exception Handling in (only) MSVC using the /EHa compiler flag caused trouble with flags defined with Cmake Generator Expressions. These expressions are not fully resolved, and they fail validation checks in check_cxx_compiler_flag(). The previous attempt at applying /EHa to only MVSC involved refactoring a direct call to target_compile_options() with a call to the Slang helper function add_supported_cxx_flags() where an additional MSVC filter was introduced, but the helper also calls check_cxx_compiler_flag() to see if flags are supported. It was okay for /EHa, but not some other flags that ended up getting newly validated. The above issue is fixed by re-implementing the change that added /EHa to only MSVC. This change goes back to adding compiler flags without the helper function with its extra validation, instead using an additional cmake generator expression to apply /EHa only to MSVC.

2024-11-06Fix the WGSL error about semantic when a nested struct is inlined (#5506)Jay Kwak
After a struct with a semantic is inlined to a newly synthasized struct, the previous semantic must be removed in order to avoid duplicated semantic on the same location. The following function is copied from slang-ir-metal-legalize.cpp, - removeSemanticLayoutsFromLegalizedStructs() This must be refactored to reduce the code duplication later.

2024-11-06Make various parameters and return types require specialization when ↵Anders Leino
targeting WGSL (#5483) Structured buffer types translate to array types in the WGSL emitter. WGSL doesn't allow passing runtime-sized arrays to functions. Similarly for pointers to texture handles. Also, structured buffers (runtime-sized arrays) cannot be returned in WGSL. This closes issue #5228, issue #5278 and issue #5288 by enabling specialized functions to be generated in these cases, in order to work around these constraints.
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>
2024-11-05Catch all exceptions in render-test (#5495)cheneym2
Catch all exceptions in render-test In MSVC, the /EHsc flag is used by default, it causes only C++ (synchronous) exceptions to be caught by try/catch blocks. The /EHa flag can instead be used to catch both synchronous C++ exceptions as well as structured asynchronous exceptions such as those seen in segfaults or other typical bugs. Using /EHa allows render-test to not crash completely if there is a buggy graphics driver in the system. Issue 5275
2024-11-05Fix system semantics of SV_GroupIndex (#5496)kaizhangNV
Close the issue #4940.
2024-11-05Fix issue of infinity float literal (#5489)kaizhangNV
* Fix issue of infinity float literal * add parameters for the test * Correct the way to construct inf and nan In WGSL, expression of "1.0/0.0" is not allowed, it will report compile error, so to construct infinity or nan, we have to assign the float literal to a variable and then use it to bypass the compile error. By doing so, we add getInfinity and getNan functions to the builtin prelude to wgsl. --------- Co-authored-by: Yong He <yonghe@outlook.com>
2024-11-05Update slang-rhi and fix error handling (#5485)cheneym2
Update slang-rhi to pick up a fix in webgpu compilation error handling. In doRenderComparisonTestRun(), only return TestResult::Pass if the shader is ran actually compiled. A similar check is in place elsewhere in slang-test-main, but was missed in doRenderComparisonTestRun(). Add two tests to the github CI skiplist, and use the skiplist in one additional CI config that was running without it. Closes 5291

* 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
