OSWORD &C8 (200) - Pass SWI Operation to Host JGH
This call passes a SWI to the host to be executed. Values passed can be translated to and from absolute ARM address by setting bits in the translate bytes. On entry: XY?0 =regs*4+8 (send block length) XY?1 =regs*4+8 (the receive block length) XY?2 =bitmap of outgoing register values to translate to ARM absolute addresses, b0=1 - r0, b1=1 - r1, etc., XY?3 =bitmap of incoming register values to translate back to local processor addresses as with XY?2 XY!4 =SWI number XY!8 =r0 value XY!12=r1 value ... continues onwards up to the number specified by XY?0 and XY?1. On exit: XY!4=b0-b3=returned flags, NZCV. [*check] If V set in b0, an error number is returned in XY!4 and the CR-terminated error string returned in XY+8 onwards.
