BURG and IBURG are not backends, just tree parser generators that can be
used to produce the instruction selection part of a back-end. One
back-end generator that works with lcc is Marion. However, I don't know if
it's available. Also, it's aimed at RISCs.
Two of our students did a globally-optimizing back-end for lcc. They had
some problems with lcc's intermediate representation. It is well
documented, but not made for global optimization and global register
allocation. Instead, lcc makes it easy to produce decent code with a
simple code generator.
