.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
|
1999-07-02 19:14:07 +04:00
|
|
|
and continues for

|
|
|

|
|
|
|
|
.Fa start
|
1999-02-10 01:32:33 +03:00
|
|
|
is 0, all the address space of the current execution thread is affected.
|
|
|
|
|
Addresses outside the specified region may be synchronized, too.
|
|
|
|
|
.Pp
|
|
|
