# gas target specific configuration file. This is a -*- sh -*- file.

# Output shell variables:
# cpu_type canonical gas cpu type; identifies the config/tc-* files
# fmt output format; identifies the config/obj-* files
# em emulation; identifies the config/te-* files
# Optional output shell variables; these are not always set:
# arch the default architecture; sets DEFAULT_ARCH on some systems
