; Pattern file for pass 1 of the Rigel microcode allocator.
; ALL MICROWORD BIT PATTERNS MUST BE AN EXACT MULTIPLE OF 4 BITS
;	Pattern 3 gives the bit mask of the 11-bit jump field in the microword.

; The following patterns identify microword bit patterns for each of the cases which need to generate constraints.
;	Pattern 101 is used everywhere an intra-page branch is used to constrain the destination of the branch to
;			have the same page number as the branch itself.
;	Pattern 102 is used for CALL to constrain the microinstruction which is the return point of the called routine
;			to the CALL itself.
