Hi,

Look for the function addPassesToEmitFile, in LLVMTargetMachine. This is
called directly from llc.cpp if I recall correctly, and will emit a
string representation of the assembler code.

If you want pure ELF, look for addPassesToEmitMachineCode (old version)
or addPassesToEmitMC (new version).

Cheers,

James
