   3 # Generates ELF, COFF and MachO object files for different architectures
   4 # containing all relocations:
   5 #
   6 # ELF:   i386, x86_64, ppc64, aarch64, arm, mips, mips64el
   7 # COFF:  i386, x86_64
   8 # MachO: i386, x86_64, arm
   9 # (see end of file for triples)
  10 #
  11 # To simplify generation, object files are generated with just the proper
  12 # number of relocations through repeated instructions. Afterwards, the
  13 # relocations in the object file are patched to their proper value.
