A port of gcc to the ROMP has been done by Richard Kenner at NYU
(kenner@vlsi1.ultra.nyu.edu).  It is an AOS (BSD) port, and seems
stable, but I haven't done any real testing.  The compiler will
compile itself.  I am currently using it on an RT 25 running Mach.
The port involved non-trivial hacking of gcc itself, mostly in the
area of instruction scheduling.

The compiler can be ftp'd from jim.ultra.nyu.edu, but only after hours.
Since none of the AOS-supplied compilers will completely compile the
code, the compressed tar file contains all the .o and binary files
and runs about 5M.

To my knowledge, nothing has been done about a port to AIX; this would
involve a change to the stack frame and call sequence, the floating
point interface, miscellaneous assembler differences, and the usual
ugliness attendant to porting BSD code to a SysV-ish system (2.2.1 is
better than some others, but it sure ain't seamless).
