◆ InitKind

Discriminator enum (for isa<>, dyn_cast<>, et al.)
This enum is laid out by a preorder traversal of the inheritance hierarchy, and does not contain an entry for abstract classes, as per the recommendation in docs/HowToSetUpLLVMStyleRTTI.rst.
We also explicitly include "first" and "last" values for each interior node of the inheritance tree, to make it easier to read the corresponding classof().
We could pack these a bit tighter by not having the IK_FirstXXXInit and IK_LastXXXInit be their own values, but that would degrade readability for really no benefit.

Member Function Documentation
◆ convertInitializerBitRange()
|
inlinevirtual |
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 in llvm::TypedInit, llvm::BitsInit, and llvm::IntInit.
◆ convertInitializerTo()
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.
Implemented in llvm::TypedInit, llvm::UnsetInit, llvm::ArgumentInit, llvm::BitInit, llvm::BitsInit, llvm::IntInit, llvm::StringInit, llvm::ListInit, and llvm::DefInit.
Referenced by llvm::CheckAssert(), llvm::BinOpInit::Fold(), llvm::TernOpInit::Fold(), llvm::CondOpInit::Fold(), llvm::UnOpInit::Fold(), and llvm::TernOpInit::resolveReferences().
◆ dump()

Otherwise, return null.
Implemented in llvm::TypedInit, llvm::UnsetInit, and llvm::ArgumentInit.
◆ getFieldType()

◆ resolveReferences()
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.
