 * Back end tables for pdp 11                           *
 * Authors : Ceriel J.H. Jacobs,Hans van Staveren       *
 *                                                      *
 * wordsize = 2 bytes, pointersize = 2 bytes.           *
 *                                                      *
 * Register r5 is used for the LB, the stack pointer    *
 * is used for SP. Also some global variables are used: *
 * - reghp~     : the heap pointer                      *
 * - trpim~     : trap ignore mask                      *
 * - trppc~     : address of user defined trap handler  *
 * - retar	: function return area for size>4       *
 *                                                      *
 * Timing is based on the timing information available  *
 * for the 11/45. Hardware floating point processor is  *
 * assumed.                                             *
