◆ 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 498 of file Record.cpp.

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

◆ convertInitializerTo()

Init * IntInit::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).

Reimplemented from llvm::TypedInit.
