[net.unix-wizards] ld -A

ptw@vaxine.UUCP (P. T. Withington) (09/28/83)

I have been playing with the ld -A feature of 4bsd.  This seems like a highly
useful feature (for my user-customizable program).  Has anyone else had
experience with it?  In particular:

	Will it stay around, e.g., in 4.2?  (Would I be a fool to depend on
	it?)

	Does -A make any sense without -N?  (I don't think so.  It doesn't
	appear to work, either.)

	Is there any library to support incremental loads?  (I have dink-ed
	something up for a test, but don't want to reinvent...)

	Does it have any meaning in an I/D machine, or a machine with execute
	protection?  (Seems like you'd need textbrk(2).)

Some folks here have used the ld -A feature to load new object modules
into PSL (Portable Standard Lisp).  I'm not sure exactly how it does it,
it was done by Russ Fish (utah-cs!fish or fish@utah-cs).
