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.

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.
