yes, I can provide the full setup, basically:

1. run the testsuite to have all the.script file generated: `lit -sv ${llvmproject_srcdir}/_build/test/MC/MachO --filter gen-dwarf.s`
2. go to test directory, for hacking: `cd ${llvmproject_dir}/llvm/test/MC/MachO`
3. run the .script file by hand from that directory: `sh ${llvmproject_srcdir}/_build/test/MC/MachO/Output/gen-dwarf.s.script`
