.Sh DESCRIPTION
|
|
.Fn m68k_sync_icache
|
|
synchronizes data and instruction caches over the specified region.
|
|
It should be called prior to executing newly generated code.
|
|
.Pp
|
|
The affected address range starts at
|
|
.Fa start
|
|
and continues for
|
|
.Fa size
|
|
bytes. If
|
|
.Fa start
|
|
is 0, all the address space of the current execution thread is affected.
|
|
Addresses outside the specified region may be synchronized, too.
|
|
.Pp
|
|
The call always succeeds.
