# This script handles target configuration for gold. This is shell
# code invoked by the autoconf generated configure script. Putting
# this in a separate file lets us skip running autoconf when modifying
# target specific information.
# This file switches on the shell variable ${targ}, which is a
# canonicalized GNU configuration triplet. It sets the following
# shell variables:
# targ_obj object file to include in the link, with no extension
# targ_extra_obj extra object file to include
# targ_machine ELF machine code for this target
# targ_size size of this target--32 or 64
# targ_extra_size extra targ_size setting for the target
# targ_big_endian whether the target is big-endian--true or false
# targ_extra_big_endian extra targ_big_endian setting for the target
# targ_osabi EI_OSABI value
# If the target is not recognized targ_obj is set to "UNKNOWN".
