differentiable args (#4901)
* Explicitly detach derivative when forming a non-differentiable struct out of differentiable args
This fixes an issue where initializer lists get optimized out and lose information about non-differentiability.
There are 2 places where this could have been fixed:
1. When coercing initializer-list exprs, we can check for non-differentiable aggregate types and use a detach derivative on all the args.
2. Add an extra case in the peephole optimization step that adds detach-derivative when simplifying a make-struct of a non-differentiable type.
Even though solution 2 is more elegant, this PR goes with solution 1 simply to avoid having to use a differentiable-type-conformance-context that is used in the auto-diff IR passes to check for differentiability.

generic types (#4602)
* Fix issue with synthesizing `Differential` type for self-differential generic types
The problem was that we were using the type that was performing the lookup for `.Differential` which can have substitutions based on the local context where the decl is being referenced.
We need to synthesize the type local to the decl itself

* 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

* Fix issue with out-of-date type resolution cache.
Witness tables created during the conformance checking phase not being taken into account during the decl type resolution phase because the epoch is not updated after conformance checking.
This leads to certain complex associated-type lookup chains (such as the one in tests/compute/assoctype-nested-lookup) not resolving properly and causing errors.

* Init expressions for struct members
Following commit handles init expressions of struct's.
The general implementation follows C++ init expression rules for classes & inherited classes.
The logic was implemented after type resolution (`SemanticsDeclAttributesVisitor`):
1. Create a default constructor if missing.
2. Check all member variables (`this` and `super`) for if a member has an init expression, continue to *3* if found.
3. For each constructor, insert a member variable's init expression at the beginning of a constructor. This is to follow how C++ does construction of objects.
Some important notes about implementation:
* We must handle the scenario that there is inheritance. To handle the inheritance information processing `findLevelsOfInheritance` was created.
* If a user manually sets overload rank's of constructor expression's we have no way to assume new default constructor overload ranks.
* address feedback
- moved all scope bound variables into if statment initializers
- added indent
- changed logic for overloadRank to be centered around positive numbers rather than negative
* Inheritance fixes universally & for struct field init
1. reimplemented struct field logic
2. implemented inheritance through calling a "super->init()" inisde a constructor for each "this".
3. implemented support for multi level inheritance (4+) and accessing members without a crash.
* add a way to ignore Forward declared constructors.
* a test and fix for a falcor failiure
the following case was not handled: creating an default Ctor due to a non L-Value struct field. Having an empty Ctor causes a warning.
* remove texture/sampler from test since it will break glsl
* get inheritance info using existing lookup logic
modified Facet lookups to store relative depth rather than arbitrary ::Self or' ::Direct for inheritance (which was 'wong' since depth 2 is not Direct, but was considered a Direct inheritance)
* cleanup unused
* cleanup unused functions and whitespace
* fix compile warning
* clean up, reorder, addressed language server fail
changed logic to safeguard bad code --> no longer breaks language server if code is incomplete.
remove the "semi-ordering" logic because caused a crash (and this code does nothing functionally, just thought it would be nice to add if '0 cost').
Remove rank setting for constructors, in place use an addition to the overload system: "this" expressions have calling priority over "super" expressions.
* undo all inheritance depth checks & code added to the inheritance checking algorithm
Reorder default ctor creation and auto-generation of constructor body.
* Handle same struct types during overload resolution
Changed overload resolution logic to properly handle same struct types; added test to check for multi-param same type function overload.
* remove unused ast object
Used unused object in an incorrect way. This caused the compiler to not flag a warning.
* extension support for default constructors
specialization is not supported with default constructors yet.
* fix bugs
Fix bug in override/overload logic with type comparisons.
used wrong type for ctor list construction
Specialization has not been added yet
* disallow default ctor inside extension
* adjust comment, add new tests
* add explicit types to invoke, use faster default ctor lookup.
* adjust syntax & naming as recomended

(#3881)
* Refactor memory qualifier decorators to be a bit-flag set.
replace GloballyCoherent, ReadOnly, WriteOnly, Volatile, and Restrict memory modifiers and decorations with a bit flag set to more efficiently manage memory qualifiers.
added `restrict` modifier to test to ensure the code works when dropping a `restrict` memory qualifier
* Refine tests & add SSBO memory qualifer support
add CHECK's to tests to ensure memory qualifiers emit as intended
added tests and changed code to ensure memory qualifiers work on SSBO objects (SPIR-V & GLSL)
* add memory qualifiers & fixes.
Add to StructuredBuffer & ByteAddressBuffer `ReadOnly`/NonWritable qualifier.
* Memory qualifiers must be decorated on a variable inst. Due to this the qualifier is added after `lowerStructuredBufferType`
Fixed an error where ReadOnly->NonReadable & WriteOnly->NonWritable
* Adjusted tests accordingly
Added back the removed `globallycoherent` memory qualifier emit'ing code in hlsl-emit (was incorrectly removed).
undo hlsl.meta changes
cleanup

resolves #3587 for GLSL & SPIR-V targets #3631 (#3810)
* [early push of code since memory qualifiers may be made into a seperate branch & pr and I rather make it simple to split the implementation if required]
all type & functions impl. for GLSL image type
added all memory qualifiers & tests for direct read/write [GLSL syntax] (DID NOT test or implement parameter qualifiers, that is next commit)
* this inlcudes emit-glsl & emit-spirv for qualifier decorations
* this also includes error handling
* this includes parsing
* full implementation other than Rect; all errors and basic tests are done & working
what is left:
1. need to now add Rect type support (additional TextureImpl flag)
2. tests
3. testing infrastructure to support variety of types
* testing framework now works with images of all types and imageBuffers -- next steps are actual tests
* push code for mostly working image atomics; missing int64/uint64 tests and slightly broken feature
likley due to missing code from master which I pushed for regular atomics
* fix all remaining shader image atomic issues and tests to work with float & i64/u64 fully
will now clean up code and squash the commits (since they are quite all over the place)
* refactor code to work & look correct, fix all regressions
Turned off tests for texture format R64 due to the shader use limitation of currently being only for storage buffers on most hardware (test fail cause, this is not allowed)
Changed raygen.slang & nv-ray-tracing-motion-blur.slang since both cross-compiled with glslang, which does not respect layout(rgba8) for RWBuffer's, in this scenario making the type into a SPIR-V rgba32f, which is incorrect and a known problem, this causes different code to be outputted from Slang & HLSL+GLSL->Slang paths
Clean up all code and better explain the "why" for the gimageDim definition we use various strings of Slang code, the gist is:
1. Parameters are structured as per IMAGE_PARAM keyword in spec, and we respect this in order to match specification (to allow easy code iteration)
2. sample parameters are required for functions
3. types are inconsistently named
fixed regression of breaking l-value lowering when r-value should be lowered (lower-to-ir)
fix compiler warnings
remove unneeded lambdas
`expr->type.isLeftValue = isMutableGLSLBufferBlockVarExpr(baseExpr) && (expr->type.hasReadOnlyOnTarget == false);` is an adjustment made such that a buffer block is mutable only if the block is mutable and the base expression is mutable (to handle case of readonly buffer block, immutable)
* remove rectangle parameter
* use proper const syntax and struct naming
* adjust syntax
* adjust modifier capabilitites: HLSL+GLSL --> GLSL. Notice most specifically, if the parent is a global struct we can put a memory qualifier, this does not include, struct inside a struct, with a member variable with a memory qualifier (since then you could use the struct in invalid ways). Added test for struct inside struct with member variable with memory qualifier.
adjust syntax and remove code which will rot
* adjust formatting for consistency
* addressing review feedback
addressing review feedback:
change testing code to handle int and float/half correctly in all cases
adjust testing code syntax as requested
change vkdevice code to fit a different form as requested
* adjust code as per requested for review:
1. adjusted testing code logic to handle non 0-1 values appropriately, notice int8_t will likley be the range and set order of {[0,127],[-1,-128]}, this is intentional
2. syntax adjustments for correctness
* trying to fix falcor regressions
* add back removed code for regression testing
* test removing changes which may break falcor
* Revert "test removing changes which may break falcor"
This reverts commit 240da97f06c23e98a26ac23cf1d385995c67b251.
* disable R64 support in attempt to fix falcor tests
* Revert "disable R64 support in attempt to fix falcor tests"
This reverts commit 317cb632eb2f47e980fc4aeafe418f8060f4c473.
* disable major device changes (still trying to figure out falcor fails -- locally working different than CI)
* test removing d3d changes
* remove all format changes
* add back removed code for regression testing
* try something to get code to work with falcor
* address review
* Add way to handle constref/ref/encapsulated texture objects with memory qualifiers as a parameter.
Fixed an issue (and improved codegen) for when we have a store(dst,load(src)) pattern, where dst is supposed to be equal to src for when resolving globalParam's (no need for work-arounds anymore)
* move recent-fix/change to textureType loading into a proper optimization pass which now runs after SPIR-V legalization to catch odd SPIR-V emitting after legalizing types for SPIR-V
* Revert most recent optimization pass change, add work around getting a unmangled global parameter address through a intrinsic op instead of spir-v intrinsic (works same as `__imagePointer()`)
* remove unneeded changes
* remove unneeded `__constref` in glsl.meta
* move memory qualifier checks to visitInvoke of check-expr.cpp
move GetLegalizedSPIRVGlobalParamAddr resolving to spirv-legalization pass
move error for "if using non texture type with memory qualifer in param" earlier such that we error with this first. No point in telling user "you are not putting correct memory qualifiers" when memory qualifiers should not have been used.
* add memory qualifier folding modifier 'MemoryQualifierCollectionModifier' to reduce searching and processing (later will be adapted to whole system) as suggested/asked.
The utility is a method to track memory qualifiers without doing a expensive linked-list traversal (image's have 4 modifiers normally).
* properly pass multiple qualifiers from checkModifier down to the `modifier`s list
* addressing review comments:
* change implementation to properly handle restrict modifier
* add comments about implementation for clarity

(#3675)
The following PR implements raytracing extensions (GLSL_EXT_ray_tracing, GLSL_EXT_ray_query, GLSL_NV_shader_invocation_reorder & GLSL_NV_ray_tracing_motion_blur); for GLSL & SPIR-V targets. Fully implements all functions, built-in variables, & syntax; resolves #3560 for GLSL & SPIR-V Targets.
notes of worth:
* __rayPayloadFromLocation, __rayAttributeFromLocation, and __rayCallableFromLocation, were added as SPIR-V Intrinsics to refer to location's of raytracing objects in SPIR-V for when using GLSL syntax.

* Implement short-circuit logic operator
Implement short-circuit evaluation for logic && and ||
operator.
The short-circuit behavior is only used when the operands
involved are scalar and the parent function is non-differentiable.
In implementation, we define a new class 'LogicOperatorShortCircuitExpr'
derived from 'OperatorExpr'. In the visitInvoke() call, we will create
a new expression object 'LogicOperatorShortCircuitExpr' if the
expression is logic && or ||. So that we can generate new IR code in the
new visit function 'visitLogicOperatorShortCircuitExpr' to implement the
short-circuit behavior.
Add new test to test the short-circuit behavior.
* Fix an compile issue occurred in Falcon test
Previously, we early return when at least one of the operands of
"&&" or "||" is vector in convertToLogicOperatorExpr call. However,
in that case the arguments involved in the expression have already been
type checked. When it falls-back to 'visitInvokeExpr', it will check
the arguments again, and some unexpected behavior could occur
which could in turn cause some internal error.
So we add a check in the 'visitInvokeExpr' to avoid double type checking
of arguments.
* Update glsl subgroup test to not use short-circuit
Since the short-circuit evaluation could cause the threads
diverging in subgroup intrinsics. So change the test to not
using "&&" to chain those subgroup intrinsics together. Instead,
using "&" to chain them together because those test functions have
the return value as bool.
* Disable short-circuit in few situations
Disable short-circuit in following situations:
1. generic parameter list
2. static const varible initialization
* Use a flag to indicate the enablement of short-circuit
Instead of using a struct to indicate the state of the outer
environment of current expression, use a simple bool flag to
indicate whether or not apply the short-circuit to current
expression because there few situations where we will disable
short-circuiting and in those circumstances, there is no nested.
Therefore, a flag is good enough to indicate the case.
* Disable short-circuit in index expression
Also fix the build issue. (A cleanup for the last change.)
* check both 'static' and 'const' modifiers
Previously we only check HLSLStaticModifier to decide whether or
not using short-circuit, but we really should check both 'static'
and 'const' modifiers together, because we only want to disable
the short circuit for init expression for 'static const' variable.
* relax the restriction of short-circuit for index expression
Disable the short-circuit for index expression only when declare
an array.
* Simplify the logic by creating subVisitor
Simplify the logic by create a sub expression visitor so
that we don't need to introduce extra recursion.
* Call convertToLogicOperatorExpr after args check
Change to call convertToLogicOperatorExpr after arguments
check in visitInvokeExpr such that we don't have to check
whether the arguments checked to avoid the double checking
issue.
