◆ convertInitializerBitRange()

Init * IntInit::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.

Definition at line 403 of file Record.cpp.

References llvm::BitInit::get(), llvm::BitsInit::get(), and llvm::ArrayRef< T >::size().

◆ convertInitializerTo()

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

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

Reimplemented from llvm::TypedInit.

Convert this value to a string form.

Implements llvm::Init.

◆ getBit()

Init* llvm::IntInit::getBit ( unsigned  Bit) const

This method is used to return the initializer for the specified bit.

◆ resolveListElementReference()

Init* llvm::IntInit::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.
