◆ convertInitializerBitRange()

Init * TypedInit::convertInitializerBitRange ( ArrayRef< unsigned Bits) const
overridevirtual

This method is used to implement the bitrange selection operator.

Given an initializer, it selects the specified bits out, returning them as a new init of bits type. If it is not legal to use the bit subscript operator on this initializer, return null.

Reimplemented from llvm::Init.

Reimplemented in llvm::IntInit, and llvm::BitsInit.

◆ convertInitializerTo()

Init * TypedInit::convertInitializerTo ( RecTy Ty) const
overridevirtual

This virtual function converts to the appropriate Init based on the passed in type.

Implements llvm::Init.

Reimplemented in llvm::DagInit, llvm::DefInit, llvm::ListInit, llvm::CodeInit, llvm::StringInit, llvm::IntInit, and llvm::BitsInit.

Definition at line 1134 of file Record.cpp.

◆ convertInitListSlice()

Init * TypedInit::convertInitListSlice ( ArrayRef< unsigned Elements) const
overridevirtual

This method is used to implement the list slice selection operator.

Given an initializer, it selects the specified list elements, returning them as a new init of list type. If it is not legal to take a slice of this, return null.

Reimplemented from llvm::Init.

Reimplemented in llvm::ListInit.

Definition at line 1231 of file Record.cpp.

◆ getFieldType()

RecTy * TypedInit::getFieldType ( StringInit FieldName) const
overridevirtual

This method is used to implement the FieldInit class.

Implementors of this method should return the type of the named field if they are of record type.

Reimplemented from llvm::Init.

Reimplemented in llvm::DefInit, and llvm::VarInit.

Definition at line 1126 of file Record.cpp.

References llvm::tgtok::Field, and getType().

◆ resolveListElementReference()

virtual Init* llvm::TypedInit::resolveListElementReference ( Record R,
const RecordVal RV,
unsigned  Elt 
) const
pure virtual

This method is used to implement VarListElementInit::resolveReferences.

If the list element is resolvable now, we return the resolved value, otherwise we return null.

Implemented in llvm::DagInit, llvm::FieldInit, llvm::DefInit, llvm::VarListElementInit, llvm::VarInit, llvm::OpInit, llvm::ListInit, llvm::CodeInit, llvm::StringInit, llvm::IntInit, and llvm::BitsInit.
