Node:mmo, Previous:elf, Up:BFD back ends
The mmo object format is used exclusively together with Professor
Donald E. Knuth's educational 64-bit processor MMIX. The simulator
mmix which is available at
<http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz>
understands this format. That package also includes a combined
assembler and linker called 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
<http://www-cs-faculty.stanford.edu/~knuth/mmix.html> for more
information about MMIX. The ELF format is used for intermediate
object files in the BFD implementation.
