CUDA: Fix compiler crash with unsized array field - nonuniformres-as-… (#8380)

2025-09-10T12:01:36+00:00

…function-parameter.slang #8315 Root Cause: CUDA compilation crashed with `assert failure: !seenFinalUnsizedArrayField` because unsized arrays like `RWStructuredBuffer globalBuffer[]` were not the final field in generated parameter structs, violating the layout constraint in slang-ir-layout.cpp. Fix: Extended `collectGlobalUniformParameters` to automatically reorder struct fields for CUDA targets - regular fields first, unsized arrays last. Other targets preserve original order. Impact: - Enables CUDA support for nonuniform resource indexing as function parameters - Zero impact on existing GLSL/HLSL/SPIRV targets - Automatic handling - no manual parameter reordering required Files: slang-emit.cpp, slang-ir-collect-global-uniforms.cpp/.h, test file --------- Co-authored-by: slangbot Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> Co-authored-by: Ellie Hermaszewska

Added NativeStringType (#2252)

2022-05-27T21:28:05+00:00

* #include an absolute path didn't work - because paths were taken to always be relative. * Use TerminatedUnownedStringSlice for literals in output C++. * Remove Escape/Unescape functions used in slang-token-reader.cpp Add target type of 'host-cpp' etc to map to the target types. * Fix some corner cases around string encoding. * Added unit test for string escaping. Fixed some assorted escaping bugs. * Updated test output. * Added decode test. * Stop using hex output, to get around 'greedy' aspect. Use octal instead.
