23# This script handles target configuration for gold.  This is shell
24# code invoked by the autoconf generated configure script.  Putting
25# this in a separate file lets us skip running autoconf when modifying
26# target specific information.
27
28# This file switches on the shell variable ${targ}, which is a
29# canonicalized GNU configuration triplet.  It sets the following
30# shell variables:
31
32# targ_obj               object file to include in the link, with no extension
33# targ_extra_obj         extra object file to include
34# targ_machine           ELF machine code for this target
35# targ_size              size of this target--32 or 64
36# targ_extra_size        extra targ_size setting for the target
37# targ_big_endian        whether the target is big-endian--true or false
38# targ_extra_big_endian  extra targ_big_endian setting for the target
39# targ_osabi		 EI_OSABI value
40
41# If the target is not recognized targ_obj is set to "UNKNOWN".
