word	The word the cfg is produced from.
post-order	The blocks of the cfg in a post order traversal sequence.
stack-frame	stack-frame of the cfg.
frame-pointer?	Whether the cfg needs a frame pointer. Only cfgs generated for #alien-callback nodes does need it. If the slot is t, then the frame pointer register (RBP on x86.64 archs) will not be clobbered by register allocation. See compiler.cfg.linear-scan for details.
