◆ convertInitializerBitRange()

const Init * BitsInit::convertInitializerBitRange ( ArrayRef< unsigned > Bits ) const

overridevirtual

This function is used to implement the bit range selection operator.

Given a value, it selects the specified bits, returning them as a new Init of type bits. If it is not legal to use the bit selection operator on this value, null is returned.

Reimplemented from llvm::TypedInit.

Definition at line 522 of file Record.cpp.

References get(), getBit(), getNumBits(), and llvm::TypedInit::getRecordKeeper().

◆ convertInitializerTo()

const Init * BitsInit::convertInitializerTo ( const RecTy * Ty ) const

overridevirtual

Convert to a value whose type is Ty, or return null if this is not possible.

This can happen if the value's type is convertible to Ty, but there are unresolved references.

◆ resolveReferences()

const Init * BitsInit::resolveReferences ( Resolver & R ) const

overridevirtual

This function 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.
