llvm-6502/lib/Target/X86/X86ELFWriter.cpp
Chris Lattner 07a9144efe Add support to the X86 backend for emitting ELF files. To use this, we
currently use: llc t.bc --filetype=obj

This will produce a t.o file which is dumpable with readelf.  Currently
the file produced is empty, but the scaffolding to do more is now in place.
