In general, this forces SILGen and IRGen code that's grabbing
a declaration to state whether it's doing so to define it.
Change SIL serialization to serialize the linkage of functions
and global variables, which means also serializing declarations.
Change the deserializer to use this stored linkage, even when
only deserializing a declaration, and to call a callback to
inform the client that it has deserialized a new entity.
Take advantage of that callback in the linking pass to alter
the deserialized linkage as appropriate for the fact that we
imported the declaration. This computation should really take
advantage of the relationship between modules, but currently
it does not.

Attribute field is a fixed 2-bit field, but cast kind exceeds 4,
so using 2-bit attribute field for cast kind will cause overflow.
The fix is to add a record for the cast instruction with a 4-bit
kind field instead of a 2-bit attribute field.

SIL instruction. Implement IR-gen support for same. Fix
the parsing of SIL string literals to properly unescape them.
SIL-gen still emits UTF8 literals unconditionally.
Swift SVN r11904
Make ApplyInst and PartialApplyInst directly take substitutions for generic functions instead of trying to stage out substitutions separately. The legacy reasons for doing this are gone.
Swift SVN r8747
Handle the following SILInstructions:
DeallocBoxInst ArchetypeMetatypeInst ClassMetatypeInst ProtocolMetatypeInst
AllocRefInst DeallocRefInst StoreWeakInst AssignInst
Add an optional 2-bit field for instruction attributes to
SILOneValueOneOperandLayout.
Swift SVN r8418
Handle the following SILInstructions:
LoadWeakInst,
Checked Conversion instructions:
DowncastInst, SuperToArchetypeRefInst,
DowncastArchetypeAddrInst, DowncastArchetypeRefInst,
ProjectDowncastExistentialAddrInst, DowncastExistentialRefInst
Add an optional 2-bit field for instruction attributes to SILOneOperandLayout
and SILOneTypeOneOperandLayout.
Update SILPrinter to print [take] for LoadWeakInst.
Swift SVN r8416
Add command line argument -sil-link-all and -sil-serialize-all for testing
purpose.
Do not create new SILFunction for de-serialized SIL, instead update the
existing declaration with the de-serialized SILFunction.
Add testing case to cover partial_apply.
Swift SVN r8410
Add serialization/deserialization of the following SILInstructions:
BuiltinFunctionRefInst, IndexRawPointerInst, ModuleInst,
Conversion instructions:
RefToObjectPointerInst, UpcastInst, CoerceInst, AddressToPointerInst,
PointerToAddressInst, ObjectPointerToRefInst, RefToRawPointerInst,
RawPointerToRefInst, RefToUnownedInst, UnownedToRefInst
DestroyAddrInst, LoadInst, StrongReleaseInst, StrongRetainInst,
TupleElementAddrInst, TupleExtractInst
Make getModule in ModuleFile public to be used by SILDeserializer, also
make addModuleRef in Serializer public to be used by SILSerializer.
Update testing case to cover the above SILInstructions.
Swift SVN r8372
Use a worklist in SIL linking to traverse the newly serialized SILFunction.
Add serialization/deserialization of the following SILInstructions:
AllocArray, Apply, FunctionRef, IntegerLiteral, Metatype, StructExtract,
Struct and Tuple.
Make getDecl and getIdentifier in ModuleFile public to be used by
SILDeserializer, also make addDeclRef and addIdentifierRef in Serializer
public to be used by SILSerializer.
Update testing case to cover the above SILInstructions.
TODO: lookupSILFunction should replace the existing empty SILFunction instead
of creating a new SILFunction.
Swift SVN r8339
Add implementation to deserialize SILBasicBlock and some SILInstructins.
Add handling of local SIL values.
Add serialization of SILType category and SILValue result number.
Swift SVN r8292
SerializedSILLoader to hold a list of SIL deserializers.
Also add an intial implementation of a linking pass that is run right after
SILGen to link the declaration of SILFunction to the actual definition in
the serialized module.
We add two blocks to the serialized module: a sil index block that
maps identifier to a function ID and also holds a list of function offsets,
and a sil block for the actual SILFunctions. We can probably use subblock
instead of two top-level blocks.
The serialization/de-serialization of the function hash table and the function
offsets are implemented. But we are missing handling of types (see FIXME in
the code).
ModuleFile::Serialized is made public to be used by SIL deserializer, as well
as ModuleFile::getType.
The SIL deserializer holds a pointer to the ModuleFile, it gets the sil cursor
and the sil index cursor from the ModuleFile. The other option is for SIL
deserializer to find the start of the two sil blocks within itself, thus having
less coupling with ModuleFile.
No testing case yet because we are missing handling of types.
Swift SVN r8206
few SIL instructions types.
This will be tested when we have a SIL deserializer. Testing cases covering
each implemented SIL instruction will be added.
