* 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. *
