Global Functions

• _forEachFieldWithKeyPath(of:​options:​body:​)
• _getResilientPointer(_:​_:​)
• swift_desanitizeMetadata(_:​)
• Block_copy(:​): Copies an objective-c block given its pointer, then returns the block back to the caller. This can be used to take a compile time block literal, and elevate it to the runtime by moving it into the heap, or if already there, by incrementing the retain counter.
• Block_release(:​): Releases an objective-c block. If the block is in the heap, this will either (1) decrement the retain count and/or (2) free the memory at the location of the block if the retain count is 0.
• swift_allocObject(:​:​_:​): For swift_allocObject (in this version of the function signature) you pass in UnsafeRawPointer Once we get all the metadata bridged replace it with ClassMetadata or similar type. Also, I'm not sure enough about how the alignment mask works to explain it. If someone feels like documenting it, that would be amazing. (zoomer problem)
• swift_allocBox(_:​): Creates and returns a structure containing an allocated heap object as well as the value itself following it.
• swift_allocateGenericClassMetadata(:​:​_:​): Allocates a ClassMetadata and returns the new memory.
• swift_allocateGenericValueMetadata(:​:​_:​_:​): Allocate a GenericValueMetadata object. This is intended to be called by the metadata instantation function of a generic struct or enum.
• swift_arrayAssignWithCopyBackToFront(:​:​_:​_:​): The type UnsafeRawPointer in the case of the array function signatures actually represent OpaqueValue*. Until That is properly bridged over, it is what it is. Any.Type Represents the self parameter or Metadata. This follows the same principle. Until the proper Array metadata is bridged, we leave it be. This may not be the best solution so every suggestion is appreciated
• swift_arrayAssignWithCopyFrontToBack(:​:​_:​_:​): Using an already existant array and associated heap object, this assigns values from the source object to the destination object by copying them from the front of the object to the back. It does this using a memove when the witness table is POD, and by using a default witness function when not POD.
• swift_arrayAssignWithCopyNoAlias(:​:​_:​_:​): Using an already existant array and associated heap object, this assigns values from the source object object to the destination by defaulting to a witness function to copy the values when not POD, but using memcpy when it is POD.
• swift_arrayDestroy(:​:​_:​): Using an already existant array, it destorys a certain amount of values from inside of it. This is done using the destroy function of the arrays witness table function destroy. There is no alternative to this so non POD values will not be able to utilize the function.
• swift_arrayInitWithCopy(:​:​_:​_:​): Taking an empty heap object and an already initialized one, this initializes the empty one by copying a certain amount of children from the initialized one. If the source object is POD, it gets copied using memcpy. If not, it utilizes the provided witness functions located in the metadata's witness table.
• swift_initWithTakeBackToFront(:​:​_:​_:​): Using an empty heap object and an already existant array, this takes values from the existant one and fills the empty one. If the metadata is POD, this is done memmove; else it is done with a witness funcion.
• swift_initWithTakeFrontToBack(:​:​_:​_:​): Using an empty heap object and an already existant array, this takes values from the existant one and fills the empty one. If the metadata is POD, this is done memmove; else it is done with a witness funcion.
• swift_initWithTakeNoAlias(:​:​_:​_:​): Using an empty heap object and an already existant array, this takes values from the existant one and fills the empty one. If the metadata is POD, this is done memcpy; else it is done with a witness funcion.
• swift_autoDiffAllocateSubContext(:​:​): For this section, UnsafeRawPointer is in place of AutoDiffLinearMapContext; of course, this is here until we exchange the code with the type implementation. I'm thinking that it would be cool to just rewrite the AutoDiffLinearMapContext to tail allocate the initial slab. This would cover their TODO and it would be in swift. Two big bonuses.
• swift_autoDiffCreateLinearMapContext(_:​): malloc's a buffer suitable for the AutoDiffLinearMapContext and returns the initialized memory. The memory passed in increases the allocation internally at the tail.
• swift_autoDiffProjectTopLevelSubcontext(_:​): Calculates and returns the address to the start of the tail-allocated sub-context.
• swift_beginAccess(:​:​_:​): Starts dynamically tracking accesses to a variable for modification monitoring. This is to ensure the exclusivity rule. Learn more about it here at https://www.swift.org/blog/swift-5-exclusivity/
• swift_bridgeObjectRelease(_:​): Decrements the strong retain count of a bridged object by one, or frees the memory if there are no longer any retains.
• swift_bridgeObjectRelease_n(:​:​): Decrements the strong retain count of a bridged object by n, or frees the memory if there are no longer any retains.
• swift_bridgeObjectRetain(_:​): Increments the retain count of the passed in object by one. Nothing happens to the object if the retain count is zero.
