Hello,
I am preparing a package that uses unlikely and likely gcc
extensions. The code includes:
<linux/compiler.h>
and this file does not exist in my toolchain's header directory. How
do I get this file? Am I missing something terribly obvious?
For now, I am considering placing a compiler.h file in the headers
directory that is similar to:
#ifndef likely
# define likely(x) __builtin_expect((!!(x)),1)
#endif
#ifndef unlikely
# define unlikely(x) __builtin_expect((!!(x)),0)
#endif
to get this package compiled.
Thanks in advance,
