+You may have noticed the 'dwarf' directory. `simple.go` is a non-optimizing
version of the compiler targeting Linux only that adds DWARF debugging
information mapping code locations onto lines in the `ir-dump.txt` byproduct
output file. It's been rewritten in Go since managing all those binary buffers
required to build the symbol table proved to be too painful in C.
