* Fix crash when handling uninitialized resource type (#6338)kaizhangNV2025-02-12
| | | | | | | | | | | | * Fix crash when handling uninitialized resource type close #6328. When declare a var with struct type, if the struct has a resource type field and it doesn't provide explicit constructor, because slang won't implicit construct such variable at declare site if user doesn't explicitly call the initializer list, we should report the resource type field uninitialized as an error to prevent future possible crash when legalize any use of such variable.

* Fix compilation on musl libc targets (#6334)Colin Marc2025-02-10
| | | | | | | | | | | | | | The musl libc replacement removed fopen64, fgetpos64, and other 64-bit variants because it's 64-bit only. However, it does have the following in its headers: #define fgetpos64 fgetpos Just importing <stdio.h> is enough to get slang compiling on musl systems like Alpine Linux. Fixes #6330.

* Use and() and or() functions for logical-AND and OR (#6310)Jay Kwak2025-02-07
| | | | | | | | | | | | * Use and() and or() functions for logical-AND and OR With this commit, Slang will emit function calls to `and()` and `or()` for the logical-AND and logical-OR when the operands are non-scalar and the target profile is SM6.0 and above. This is required change from SM6.0. For WGSL, there is no operator overloadings of `&&` and `||` when the operands are non-scalar. Unlike HLSL, WGSL also don't have `and()` nor `or()`. Alternatively, we can use `select()`.

* Don't overwrite existing module decl scopes when parsing new source files ↵Anders Leino2025-02-06
| | | | | | | | | | | | | | | | (#6292) When a module consists of multiple source files, the module scope gets over-written for each source file that's parsed into the module. The result is that if you do something like the following, where source1.slang contains an import statement, then the imported module will get imported into the module scope corresponding to source2.slang, but won't be found from the scope of source1.slang. slangc source1.slang source2.slang # 1 module from 2 source files This patch fixes this problem by not over-writing existing container decl scope when parsing new source files into the container. This closes $6221.

* Enable D3D12 experimental feature to use coopvec (#6290)Jay Kwak2025-02-05
| | | | | | This commit enables "D3D12-experimenta-feature" in render-test. This is required to use CoopVec feature with dxcompiler.dll. But it is enabled only when "-dx12-experimental" is used, because it appears that DX12 becomes unstable when the experimental feature is enabled, which causes bunch of tests randomly failing.

* Feature/initialize list side branch (#6058)kaizhangNV2025-02-05
| | | | | | | | | | | | | | | | | | | | | | * SP004: implement initialize list translation to ctor - We synthesize a member-wise constructor for each struct follow the rules described in SP004. - Add logic to translate the initialize list to constructor invoke - Add cuda-host decoration for the synthesized constructor - Remove the default constructor when we have a valid member init constructor - Disable -zero-initialize option, will re-implement it in followup (#6109). - Fix the overload lookup issue When creating invoke expression for ctor, we need to call ResolveInvoke() to find us the best candidates, however the existing lookup logic could find us the base constructor for child struct, we should eliminate this case by providing the LookupOptions::IgnoreInheritance to lookup, this requires us to create a subcontext on SemanticsVisitor to indicate that we only want to use this option on looking the constructor. - Do not implicit initialize a struct that doesn't have explicit default constructor.

* Fix autodiff issue for vector<T, N> (#6275)kaizhangNV2025-02-05
| | | | | | | | | | | | | | | | * Fix autodiff issue for vector<T, N> Close #6154 We didn't implement correctly for vector<T, N> regarding the differentiablity. As we check differentiable before specialization, however according to the definition of vector, it has to be specialized to IFloat to know it's conformed to IDifferential type. Therefore for parameter type vector<T, N> will become no_diff. Therefore, we change the implementation a to make it explicit conform to IDifferential type. * fix typo

* Update Slang-RHI and enable any debug layers up-front (#6226)Anders Leino2025-01-31
| | | | | | | | | | | | | | | | | | | | * Update Slang-RHI and enable any debug layers up-front As [1] shows, creating a D3D12 device and then enabling debug layers causes future device creation to fail. That means enabling debug layers is a process-wide decision that should be done at startup, and not just before creating an individual device. Previously, Slang-RHI enabled debug layers as part of device creation. The new Slang-RHI revision doesn't do that anymore, but instead allows the user to enable debug layers earlier, with a separate API. This change calls the mentioned API before creating any device. This closes #6172. * Compile fixes needed after updating slang-rhi --------- Co-authored-by: Yong He <yonghe@outlook.com>

* Respect per-target debug options (#6193)Anders Leino2025-01-31
| | | | | | | | | | | | | | | | | * Base compiler options for targets on target-specific compiler options Before this change, the target compiler options were based on the linkage-wide compiler options, which where later again inherited from (basically a no-op). With this change, the target-specific compiler options are added first, and then the linkage-wide comnpiler options are inherited from. * Remove debug instructions if target-specific setting is NONE This helps to address #6092. * Make sure the linkage debug info level is sufficient for each target This closes #6092.
