The mmo object format is used exclusively together with Professor
Donald E.@: Knuth's educational 64-bit processor MMIX. The simulator
@command{mmix} which is available at
- @url{http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz}
+ @url{http://mmix.cs.hm.edu/src/index.html}
understands this format. That package also includes a combined
assembler and linker called @command{mmixal}. The mmo format has
no advantages feature-wise compared to e.g. ELF. It is a simple
non-relocatable object format with no support for archives or
debugging information, except for symbol value information and
line numbers (which is not yet implemented in BFD). See
- @url{http://www-cs-faculty.stanford.edu/~knuth/mmix.html} for more
+ @url{http://mmix.cs.hm.edu/} for more
information about MMIX. The ELF format is used for intermediate
object files in the BFD implementation.
two remaining bytes, called the @samp{Y} and @samp{Z} fields, or
the @samp{YZ} field (a 16-bit big-endian number), are used for
various purposes different for each lopcode. As documented in
- @url{http://www-cs-faculty.stanford.edu/~knuth/mmixal-intro.ps.gz},
+ @url{http://mmix.cs.hm.edu/doc/mmixal.pdf},
the lopcodes are:
