2025-10-13T14:14:45+00:00

Closes https://github.com/shader-slang/slang/issues/8154 However there is further design work to do on implementing the "NonAddressableType" suggestion

Add slangc flag to `-zero-initialize` all variables (#3987)

2024-06-12T16:46:24+00:00

* Default (zero'd) values with `-zero-initialize` flag Adds `-zero-initialize` flag to set values to a __default() expression if they are missing a initExpr. * address review and ensure __default calls ctor + zero's fields. 1. We must keep zero-initialize in SemanticsDeclHeaderVisitor. This is done because else a ctor will be initialized before we can set struct fields to `__default`. 2. IRDefaultCtorDecoration was added to track default ctor's with parent struct. 3. ParentAggTypeModifier was added to track ChildOfStruct->IRType for sharing data such as with functions. This is required to ensure we associate a lowered function with a lowered struct type * Removed decoration to track defaultCtor in favor of field. This was done since decorations are checked for IR objects, storing auxillary info does not work here as a result if usable object. * address some review comments Since `IDefaultInitializable` is taking a considerabley larger amount of time than anticipated I am pushing some of the other fixes requested. I did not remove the "IRStruct storing a default Ctor" hack yet. mostly renamed/adjusted tests to work as intended added test to ensure we don't synthisize a junk `= 0` when not in `zero initialize` mode removed member in favor of sharedContext+dictionary. * a working but incorrect impl * default init without any IR hacks (fully working aside from generic/containored-types) * Finish zero init code 1. IDefaultInitializer interface was added. If conforming, your type may be zero-initialized. To Conform a `__init()` is required 2. `[OnlyAutoInitIfForced]` was added. This attribute states that a default initializer should only be implicitly called if forced by the compiler (`zero-initialize` for example). This allows types which implicitly/explicitly conform to IDefaultInitialize to have optional auto-init behavior (which is Slang's default for user structs) to be disabled. * note about `[OnlyAutoInitIfForced]`. This is required for std-lib to not automatically resolve init-expressions for std-lib, but it has the added benifit of allowing user made structs/classes to control the default behavior of initializing * fix ErrType assumption * testing why dx12 fails local but passes CI * push vector changes to generic test * push syntax adjustment, still figuring out what is wrong with cuda. * remove debug changes & adjust style * fix field-init expressions with structs initializers don't init a static in a ctor. This would be illegal code and wrong code (init list in lower-to-ir) * minor adjustments temporarily while the rest of the issue is discussed * fix * implement IDefaultInitializable * remove a unneeded whitespace change * fix type checking error should be checking if a valid type is `Type`, not `BasicExpressionType` * needs to be DeclRefType, not Type * fix langguage server error * change findinheritance for correctness + cleanup * remove return false verified the issue was `findInheritance` * push attempt at language server fix * still trying to fix inheritance * added extension support, remove redundant code Did not address all review comments yet, want to see if CI also passes my changes * undo a change which caused CI to fail * change logic + DefaultConstructExpr setup code to use defaultConstructExpr when possible to construct a default without overhead of invoke/related also changed code so parent's defaultInitializable propegates to derived member * 1. fix error in `isSubtype` 2. add flag to isSubtype `subtypeInheritanceIsNotFullyResolved` was added since we may not be done the lookup stage but still require `isSubtype` checking to verify usage of inheritance while working with inheritance. In This case we will just skip `ensureLookup` and "caching" (since we don't have a cache invalidation system, nor need) * fix bug in logic + add test to better catch the bug * address comment + isSubTypeOption + wrapper type test, * fix wrong code adjustment I checked on the CI and realized I caused a failure, mistake was made not negating some code * syntax, class naming capital * remove stdlib default initialize changes, replace with `__default()` for init * remove redundant code + fix defaultConstruct emitting previously defaultConstruct emitting was crashing due to having generics unresolved. By not resolving the default construct immediately, everything works. * remove a coment * add test to ensure static variables dont `init` inside a struct's `__init` * fix Ptr members breaking struct use * address review and add -zero-initialize test `-zero-initialize` test was added to be sure debug pointers are not broken with default init values --------- Co-authored-by: Yong He
