…ooks Programs that SetFunction() ExitIntr() and Schedule(), or replace ex_LaunchPoint, were never called on m68k (issue #1460). - SFF_SoftInt, SFF_QuantumOver and the pending-switch flag (now SFF_AttnSwitch, replacing ARF_AttnSwitch in AttnResched) are SysFlags bits 13, 14 and 15 on every target, as on Kickstart. Cause() updates SysFlags atomically unless AROS_NO_ATOMIC_OPERATIONS is set. - m68k interrupt handlers leave through the ExitIntr() vector with SysBase pushed, as Kickstart's level handlers do, and ExitIntr() pops it. - m68k Schedule() decides with interrupts masked, as on Kickstart, so the scheduler's non-atomic flag updates cannot lose a bit. - m68k Dispatch() enters the task through ex_LaunchPoint, publishing its own launch code there on first use.
