- Just a small side note. You will find that generating object or

-quite a bit. Since they're going for object compatibility across all the

- Just a though...

Further thoughts on directly generating object code.
What happens when AT&T, in their infinite wisdom, changes object
code formats from COFF to something else? ( which I understand is to
happen with System V release 4 or 5. ) It's now time to rewrite the
object code generator for the compiler. Generating as(1) source keeps
all of that sort of stuff out of the compiler writers hair ( and they
have enough stuff in their hair as it is... ) Let as worry about the
object file format, and have all the compilers generate as(1) source,
and start up as(1).
Just think, if the MS-DOS world had standardized on one
assembler, with an enter and leave pseudo instructions, it wouldn't be
so hard today to link together products from different compiler
vendors...
Food for thought,
Eric.
