IMPORT M3Context, M3Args, M3LInitOrder, M3LTypeCodes;
This module defines the interface between the pre-linker front-end
and a back-end. In order to support multiple back-ends simultaneously,
the interface is in terms of procedure variables, which must be assigned
by an appropriate implementation.
TYPE
RunProc = PROCEDURE(
c: M3Context.T;
h: M3LInitOrder.T;
tcl: M3LTypeCodes.T
): INTEGER RAISES {};
Activate the pre-linker back end on context 'c, h'. Result < 0 if error
RegisterArgsProc = PROCEDURE(t: M3Args.T) RAISES {};
To register any back-end specific arguments
HardWiredProc = PROCEDURE(interface, proc: TEXT): BOOLEAN RAISES {};
Is 'interface.proc' hard-wired in the implementation, and therefore no
message about it being unimplemented need be generated.
VAR
Run: RunProc;
RegisterArgs: RegisterArgsProc;
HardWired: HardWiredProc;
