Detailed Description

'{ a, b, c }' - Represents an initializer for a BitsRecTy value.

It contains a vector of bits, whose size is determined by the type.

◆ convertInitializerBitRange()

Init * BitsInit::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::TypedInit.

◆ convertInitializerTo()

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

◆ getBit()

◆ resolveListElementReference()

Init* llvm::BitsInit::resolveListElementReference ( Record R,
const RecordVal RV,
unsigned  Elt 
) const
inlineoverridevirtual

This method is used to implement VarListElementInit::resolveReferences.

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

Implements llvm::TypedInit.

Definition at line 523 of file Record.h.

References llvm_unreachable.

◆ resolveReferences()

Init * BitsInit::resolveReferences ( Record R,
const RecordVal RV 
) const
overridevirtual

This method is used by classes that refer to other variables which may not be defined at the time the expression is formed.

If a value is set for the variable later, this method will be called on users of the value to allow the value to propagate out.

Reimplemented from llvm::Init.
