Hi Chris,

I am looking for assembly low level machine instruction file. So, input
file can be either IR bytecode or executable bit code file and I want
output as low level machine instruction file. Assembly file having
instructions like mov, push, pop, add, sub etc etc. Command which can take
LLVM specific bytecode or bitcode as input and generates assembly file in
the output.
