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.
