If 66.Fa start 67is 0, all the address space of the current execution thread is affected. 68Addresses outside the specified region may be synchronized, too. 69.Pp 70The call always succeeds. 71 72.Sh SEE ALSO 73.Xr arm32_sync_icache 2 74 75.Sh HISTORY 76.Fn m68k_sync_icache 77appeared first in 78.Nx 1.4. 79 80.Sh AUTHORS 81Ignatios Souvatzis 82
