/**
 * likely - macros for annotating likely/unlikely branches in the code
 *
 * Inspired by Andi Kleen's macros for the Linux Kernel, these macros
 * help you annotate rare paths in your code for the convenience of the
 * compiler and the reader.
 *
 * With CCAN_LIKELY_DEBUG defined, it provides statistics for each
 * likely()/unlikely() call.
 *
 * License: LGPL (v2.1 or any later version)
 * Author: Rusty Russell <rusty@rustcorp.com.au>
 *
 * Example:
 *	#include <ccan/likely/likely.h>
 *	#include <stdio.h>
 *
 *	int main(int argc, char *argv[])
 *	{
 *		// This example is silly: the compiler knows exit() is unlikely.
 *		if (unlikely(argc == 1)) {
 *			fprintf(stderr, "Usage: %s <args>...\n", argv[0]);
 *			return 1;
 *		}
 *		for (argc++; argv[argc]; argc++)
 *			printf("%s\n", argv[argc]);
 *		return 0;
 *	}
