2025-07-25Fix SPIRV OpMemberName member indices (#7912)davli-nv
OpMemberName instructions were all using member index 0 instead of incrementing indices (0, 1, 2, ...) as required by the SPIR-V spec. The bug was that the member index increment (id++) was only happening for physical struct types, but OpMemberName emission occurs for all struct types when they have name decorations. This fix ensures member indices are properly incremented for both physical and non-physical struct types.

* Fix metallib-asm target parsing by adding missing comma The metallib-asm target was not being recognized from command line because of a syntax error in the target string definition in slang-type-text-util.cpp. A missing comma after the first "metallib-asm" string caused C++ string literal concatenation to create a malformed string.

2025-07-24Avoid early specialization for witness tables in SimplifyIR (#7636)Jay Kwak
* Avoid early specialization for witness tables in SimplifyIR Prevents SimplifyIR from prematurely specializing witness tables before the main specialization pass. Witness tables are hoistable immutable objects that must maintain consistent signatures to avoid incorrect deduplication. SimplifyIR was incorrectly transforming expressions like "witness_table_t(%IFoo)(specialize(%7, %GenericValue4))" into "witness_table_t(%IFoo)(%Foo)" even when %GenericValue4 was unused. Fixes #7233 * Add a missing test file

2025-07-24Organize code better by splitting some big files (#7890)Theresa Foley
* Organize code better by splitting some big files The basic change here is that the majority of the declarations in `slang-compiler.h` have been split out into a set of smaller and more focused files. As a result, the implement of those declarations have been moved from `slang-compiler.cpp` and `slang.cpp` over to those new files when the proper home for code is obvious. I have tried as much as possible to *not* make any edits to the code along the way, and just copy-paste declarations from one place to another as-is. The exceptions I am aware of are: * In some cases a function that used to be file-scope `static` was used by code that landed in two or more different `.cpp` files. In these cases, I changed the function to be non-`static` (removing the `_` prefix from its name, if it had one, per our naming conventions), and put a declaration for the function into the most appropriate header I could identify. * I added a few comments in places where I saw ugly or unfortunate things in the code I was moving, and wanted to tag them with `TODO`s so we can hopefully get to them in the fullness of time. * I added top-level comments to each of the new `.h` files that was introduced to try to explain the logic for what goes into that file. * In cases where one of the new header files mostly existed to declare a single type, I sometimes added more detail to the doc comment on that type, to better explain the type and its role in the compiler (this is text that otherwise might have gone into the comment at the top leve lof the file, but I figured that the doc comment would have higher discoverability). I expect that the most contentious choice here is that the `Session` class lands in `slang-global-session.h` while `slang-session.h` holds the `Linkage` class. The names used in this change are consistent with how the relevant concepts in the public Slang API are named, and are consistent with how we *intend* to rename the classes themselves in time. * format code * fixup --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

2025-07-22Fix scalar to array conversion for tessellation factors (#7837)Yong He
* Fix scalar to array conversion for tessellation factors in GLSL legalization Add scalar-to-array conversion support in adaptType() function to handle cases where users declare scalar tessellation factors (e.g., float TessLevelInner) but GLSL requires arrays (float[2] for gl_TessLevelInner). This prevents the generation of BuiltinCast instructions that crash the SPIR-V emitter. Fixes crash: "unimplemented: Unhandled local inst in spirv-emit: BuiltinCast" - Add scalar-to-array case in slang-ir-glsl-legalize.cpp adaptType() - Fill all array elements with the scalar value for tessellation factors - Add test case for scalar tessellation factor conversion Fixes #7000 Co-authored-by: Yong He <csyonghe@users.noreply.github.com> * Apply review feedback fixes - Change test directive to TEST:SIMPLE - Use IRArrayType instead of IRArrayTypeBase - Use MakeArrayFromElement for cleaner scalar-to-array conversion Co-authored-by: Yong He <csyonghe@users.noreply.github.com> * Fix type conversion in scalar-to-array tessellation factor conversion Convert scalar value to array element type before creating array to handle cases where scalar type differs from array element type (e.g., int to float[3]).

2025-07-22Fix segfault when using -separate-debug-info with unsupported targets (#7777)Copilot
* Initial plan * Fix segfault when using -separate-debug-info with unsupported targets Add validation to emit a diagnostic error when -separate-debug-info is used with targets other than SPIR-V binary. Previously, this would cause a segfault because the separate debug info logic is only implemented for SPIR-V targets. Changes: - Added new diagnostic error (ID 18) for unsupported separate debug info usage - Added validation in OptionsParser::_parse() to check target compatibility - Created test cases for HLSL and GLSL targets to verify the fix - Updated error message to clarify only SPIR-V binary targets are supported The fix prevents segfaults and provides clear feedback to users about target limitations for the -separate-debug-info option.

2025-07-22Fix findFunctionByNameInType to preserve functions with different signatures ↵Copilot
(#7827) findFunctionByNameInType was only returning one function when multiple functions existed with the same name but different signatures. This broke reflection functionality for extension methods. Fix the issue by changing findDeclFromStringInType by not calling maybeResolveOverloadedExpr if checkedTerm is overloaded functions. We still call maybeResolveOverloadedExpr when any candidates in the overloaded list is not DeclRefExpr referencing a function.

2025-07-17slang: Add support for generating getters for IR struct defs. (#7725)Sruthik P
This change expands the IR struct definition generation logic in slang-ir.h.lua to code generate the getters for the operands of an IR. To facilitate the above, the schema for the IR definitions in slang-ir-insts.lua is updated to allow for explicit specification of the operands of an IR, with Fiddle code generating the getters for them. slang-ir.h is updated to remove the hardcoded getters of the IRs since they are now generated by Fiddle. Fixes part of #7185
