sambe is a compiler backend. It takes QBE IR as input, and emits x86-64 assembly as output.

You'll need the OCaml package manager opam installed. Using opam, you should install utop, extlib and ounit:

 opam install utop ounit extlib

Then, to build sambe:

 make ./sambe.native test.ssa output.s # sambe produces assembly meant to be compiled with NASM.

First run make sambe.byte to produce .cmo files for all the modules. Then, run utop in the sambe directory. This should start a toplevel with all the modules loaded in.
