; THIS HEADER FILE CONTAINS THE ASSEMBLY PARAMETERS FOR THE COMPILER. YOU
; SHOULD EDIT THIS FILE TO AGREE WITH YOUR SOURCE AND OBJECT HARDWARE AND
; THEN COMPILE THE COMPILER. THERE ARE NO CHECKS; IF YOU SCREW  UP  THESE
; PARAMETERS THE COMPILER MAY NOT RUN, OR IT MAY WORK PERFECTLY, OR  JUST
; SILENTLY GENERATE BAD CODE. YOU HAVE BEEN WARNED.
;
; THESE ARE THE OPTIONS. IN ALL CASES DEFINING THE SYMBOL SERVES TO  TURN
; ON THE OPTION.
;
; C$$EIS	COMPILATION MACHINE HAS EIS. SELECTIVELY ENABLES A NUMBER
;		OF EIS INSTRUCTIONS IN THE COMPILER. MAKES THE COMPILE  A
;		TINY BIT SMALLER BUT DOESN'T SPEED IT UP MUCH.
;
; T$$SXT	TARGET MACHINE HAS SXT. THIS PERMITS SXT INSTRUCTIONS  TO
;		BE USED IN CODE TABLE ENTRIES FOR INT TO LONG CONVERSIONS
;
; T$$XOR	TARGET MACHINE HAS XOR. THIS PERMITS XOR INSTRUCTIONS  TO
;		BE USED IN CODE TABLE ENTRIES FOR "^" AND "^=" OPERATIONS
;		THESE OPERATIONS (DUE TO CLEVER DESIGN OF THE XOR)  ARE 2
;		REGISTER OPERATIONS IF THE XOR INSTRUCTION IS USED;  ONLY
;		TIME WILL TELL IF THIS IMPROVES THE CODE MUCH. 
;
; T$$EIS	TARGET MACHINE HAS EIS. THIS PERMITS MUL,  DIV AND ASH[C]
;		TO BE USED IN CODE TABLE ENTRIES. SMALLER AND FASTER CODE
;		IS OBTAINED. A COMPILER THAT IS COMPILING CODE TO BE  PUT
;		IN AN LSI-11 ROM SHOULD NOT ENABLE THIS OPTION BECAUSE OF
;		A BUG IN THE PROCESSOR MICROCODE THAT MAKES IMMEDIATE OPS
;		TRAP TO 4 IN THE ROM.
;
; T$$FIS	TARGET MACHINE HAS A FIS. ENABLED FOR 11/40'S AND ANY LSI
;		MACHINE WITH THE FIS CHIP. SUBROUTINES ARE USED TO DO ANY
;		COMPARES AND TO CLEAR A FLOAT OFF THE STACK RETAINING THE
;		CODES, ALTHOUGH FIS INSTRUCTIONS ARE USED IN THE ROUTINES
;		IN FIS MACHINES. A GOOD FLAG TO SET IF YOU CAN.
;
; T$$FPP	TARGET MACHINE HAS AN FPP. ENABLED FOR BIG  MACHINES  AND
;		ON 11/23'S WITH THE FPP CHIP. MAKES FLOATS AND DOUBLES BE
;		2 AND 4 WORDS (INSTEAD OF BOTH 2 WORDS). IF YOU ARE LUCKY
;		ENOUGH TO HAVE AN FPP SET THIS!
;
; T$$DMR	USE RITCHIE'S CALLING SEQUENCE. THIS OPTION IS IMPLIED BY
;		THE T$$UNX OPTION.
;
; T$$UNX	THIS OPTION ENABLES THE COMPILATION OF A UNIX  COMPATABLE
;		.S FILE. RITCHIE'S CALLING SEQUENCE IS USED. TEMP. LABELS
; 		ARE LN: INSTEAD OF .N:. THE PSECT DIRECTIVES ARE REPLACED
;		BY .TEXT, .DATA AND .BSS. EXTERNAL SPACE IS ALLOCATED VIA
;		A .COMM. AN UNDERBAR IS PREPENDED TO ANY EXTERNAL NAMES.
