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()

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

Convert to an initializer whose type is-a Ty, or return nullptr if this is not possible (this can happen if the initializer's type is convertible to Ty, but there are unresolved references).

◆ resolveReferences()

Init * BitsInit::resolveReferences ( Resolver R) 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.
