Ada compiler for protected-mode 80286?

Ada compiler for protected-mode 80286?

[Dave Littell]

Hi,

Is there an Ada compiler that will generate code for an 80286 in
protected mode?  Can x86 GNAT be convinced to do this?


Thanks,
Dave

Well, the first Alsys Ada compiler (released in 1985) did precisely that. I
doubt if there is much interest in this "legacy" platform, but perhaps you
could find an old copy somewhere.

I don't know about GNAT, but the 16-bit Janus/Ada does not do segment
math, so it should work in a protected mode environment. You'd have to
write (or get) the code to put the processor into that mode in the first
place (we don't have it, and setting up the memory stuff is not that
simple), but once there, the code would work fine.

The 16-bit Janus/Ada 83 is still available; look at www.rrsoftware.com
or contact me directly.

There is no current port of GNAT to the 80286, and this would be a major
project to produce one.
