2024-11-21Enable some rendering tests (#5623)Anders Leino
* render-test: Add copy-source usage for render targets I found that Slang-RHI/WGPU was not able to copy from render targets to staging buffers. This helps to address issue #4943. * Add entries to render API util infos Entries for glsl-cross and glsl-rewrite are added. Without glsl-cross, slang-test fails to select a back-end, and winds up crashing when tests/render/cross-compile-entry-point.slang is enabled tests/render/cross-compile0.hlsl fails similarly without glsl-rewrite. * Enable some rendering tests * Add expected test outputs
2024-11-20Change how DeclRef::toText works (#5592)Sai Praveen Bangaru
* Change how DeclRef::toText works We now ignore the decl-ref heirarchy since that only includes nodes with specialization info & simply walk up the tree of decls, while emitting any specializations present in the decl-ref. * Update some tests.

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. This closes #5516. * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

2024-11-06Fix the logic bug in spirv-emit compile option (#5512)kaizhangNV
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. Co-authored-by: Yong He <yonghe@outlook.com>
2024-11-06Fix IntVal unification logic to insert type casts + buffer element lowering ↵Yong He

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>
