Member Function Documentation

unsigned llvm::MachOWriter::MachOHeader::cmdSize

(

bool

is64Bit

)

const [inline]

cmdSize - This routine returns the size of the MachOSection as written to disk, depending on whether the destination is a 64 bit Mach-O file.

Definition at line 219 of file MachOWriter.h.

void llvm::MachOWriter::MachOHeader::setMagic	(	bool	isLittleEndian,
		bool	is64Bit
	)			[inline]

setMagic - This routine sets the appropriate value for the 'magic' field based on pointer size and endianness.
