◆ getAlignment()

llvm::Align CIRDataLayout::getAlignment	(	mlir::Type	ty,
		bool	useABIAlign ) const

Internal helper method that returns requested alignment for type.

◆ getTypeAllocSize()

llvm::TypeSize cir::CIRDataLayout::getTypeAllocSize ( mlir::Type ty ) const

inline

Returns the offset in bytes between successive objects of the specified type, including alignment padding.

If Ty is a scalable vector type, the scalable property will be set and the runtime size will be a positive integer multiple of the base size.

This is the amount that alloca reserves for this type. For example, returns 12 or 16 for x86_fp80, depending on alignment.

◆ getTypeAllocSizeInBits()

llvm::TypeSize cir::CIRDataLayout::getTypeAllocSizeInBits ( mlir::Type ty ) const

inline

Returns the offset in bits between successive objects of the specified type, including alignment padding; always a multiple of 8.

If Ty is a scalable vector type, the scalable property will be set and the runtime size will be a positive integer multiple of the base size.

This is the amount that alloca reserves for this type. For example, returns 96 or 128 for x86_fp80, depending on alignment.

◆ getTypeStoreSize()

llvm::TypeSize cir::CIRDataLayout::getTypeStoreSize ( mlir::Type ty ) const

inline

Returns the maximum number of bytes that may be overwritten by storing the specified type.

If Ty is a scalable vector type, the scalable property will be set and the runtime size will be a positive integer multiple of the base size.

For example, returns 5 for i36 and 10 for x86_fp80.

◆ reset()

void CIRDataLayout::reset ( mlir::DataLayoutSpecInterface spec )

Parse a data layout string (with fallback to default values).
