57.Fn m68k_sync_icache
58synchronizes data and instruction caches over the specified region.
59It should be called prior to executing newly generated code.

61The affected address range starts at
62.Fa start
63and continues for
64.Fa size
65bytes. If
66.Fa start
67is 0, all the address space of the current execution thread is affected.
