| H A D | cmpxchg-xchg.h | 9e3f84ce Fri Jan 08 01:23:58 CST 2016 Michael S. Tsirkin <mst@redhat.com> sh: move xchg_cmpxchg to a header by itself
Looks like future sh variants will support a 4-byte cas which will be
used to implement 1 and 2 byte xchg.
This is exactly what we do for llsc now, move the portable part of the
code into a separate header so it's easy to reuse.
