Detailed Description

C++ view class that accepts both !cir.struct and !cir.union types.

Follows the MLIR BaseMemRefType pattern: StructType and UnionType are the concrete tablegen types; RecordType is a hand-written view class that covers both. Use it when code must handle either kind generically.

Methods that are common to both types are forwarded through dyn_cast dispatch. Type-specific methods (getPadding, getUnionStorageType) are only available on the concrete type.

Member Function Documentation

classof()

bool cir::RecordType::classof ( mlir::Type t )

inlinestatic

Definition at line 155 of file CIRTypes.h.

complete()

void RecordType::complete	(	llvm::ArrayRef< mlir::Type >	members,
		bool	packed,
		mlir::Type	padding,
		llvm::ArrayRef< RecordMemberKind >	memberKinds )

padding is union-only.

A struct carries its padding as a member marked pad.

getAllDataKinds()

llvm::SmallVector< RecordMemberKind > RecordType::getAllDataKinds ( llvm::ArrayRef< mlir::Type > members )

static

One Data kind per member.

Takes the member list rather than a count so the length cannot drift from the record it describes.
