llvm dev - Mar 2013 - [LLVMdev] Tool to convert to backend assembly instruction file

Hello,

I am looking for tool to convert  file from either (.s) bytecode or (.bc)
bitcode to .asm file. Basically assembly instruction file for my x86
backend. I think so we can use llvm-objdump. However I am not able to
figure out its exact options. Could you please tell me how to do that?

Teja,

Your mention of .s being bytecode confuses me, but if you're asking how to
lower a bitcode (.bc) or IR file (.ll) to assembly (.s) than llc is the tool you
are looking for.

llc -O2 path/to/bitcode/input.bc -o output.s

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.

Thanks,
Teja
