#!/usr/bin/env python

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