[M3devel] -check_procs?

[Jay K]

The front end has a lot of internal options.


Here is one: -check_procs.
It has one effect:

PROCEDURE Gen_Call_indirect (t: Type;  cc: CallingConvention) =  BEGIN    IF Host.doProcChk THEN Check_nil (RuntimeError.BadMemoryReference); END;

Does it really make sense that we use this for NT/x86 and only NT/x86?I kind of think we should use it never or use it always.Or use it on all but NT/x86 -- where the exception handling mechanism is pretty well defined and easy to program. We use it on NT/x86 only (the opposite of my suggestion).

Using it always would bloat our code but trivially give us "safe" portable/consistent behavior.The Modula-3 code would stop right away by calling portable code.Instead of triggering whatever platform-specific signal/exception.

I happened on this code...looking at other stuff...obvious reasons if you look around...
