◆ 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.

◆ convertInitializerBitRange()
|
inlinevirtual |
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 in llvm::IntInit, llvm::BitsInit, and llvm::TypedInit.
◆ convertInitializerTo()
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).
Implemented in llvm::DefInit, llvm::ListInit, llvm::CodeInit, llvm::StringInit, llvm::IntInit, llvm::BitsInit, llvm::BitInit, llvm::UnsetInit, and llvm::TypedInit.
Referenced by llvm::UnOpInit::Fold(), and llvm::TernOpInit::resolveReferences().
◆ convertInitListSlice()
This method is used to implement the list slice selection operator.
Given an initializer, it selects the specified list elements, returning them as a new init of list type. If it is not legal to take a slice of this, return null.
Reimplemented in llvm::ListInit, and llvm::TypedInit.
◆ dump()
| LLVM_DUMP_METHOD void Init::dump | ( | ) | const |
Debugging method that may be called through a debugger, just invokes print on stderr.

◆ getAsString()
|
pure virtual |
Convert this value to a string form.
Implemented in llvm::DagInit, llvm::FieldInit, llvm::VarDefInit, llvm::DefInit, llvm::VarListElementInit, llvm::VarBitInit, llvm::VarInit, llvm::IsAOpInit, llvm::FoldOpInit, llvm::TernOpInit, llvm::BinOpInit, llvm::UnOpInit, llvm::ListInit, llvm::CodeInit, llvm::StringInit, llvm::IntInit, llvm::BitsInit, llvm::BitInit, and llvm::UnsetInit.

◆ getAsUnquotedString()
|
inlinevirtual |
Convert this value to a string form, without adding quote markers.
This primaruly affects StringInits where we will not surround the string value with quotes.
Reimplemented in llvm::CodeInit, and llvm::StringInit.
Definition at line 367 of file Record.h.
References llvm::RecTy::dump(), and llvm::RecTy::getAsString().
Referenced by QualifiedNameOfImplicitName(), and llvm::Record::resolveReferences().
◆ getBit()
This method is used to return the initializer for the specified bit.

Referenced by llvm::BitsInit::resolveReferences(), and llvm::VarBitInit::resolveReferences().
◆ getCastTo()
If this initializer is convertible to Ty, return an initializer whose type is-a Ty, generating a !cast operation if required.
Otherwise, return nullptr.
Implemented in llvm::UnsetInit, and llvm::TypedInit.
Referenced by QualifiedNameOfImplicitName(), and llvm::RecordVal::setValue().
◆ getFieldType()

inlinevirtual |
This method is used to implement the FieldInit class.
Implementors of this method should return the type of the named field if they are of record type.
