# This is the GCC build-, host- and target-specific configuration file
# where a configuration type, as recognized and generated by config.bfd,
# is mapped to different system-specific definitions and files.  This is
# invoked by the autoconf-generated configure script, called for build,
# host and target in that order, setting ${machine} to each.  Putting it
# in a separate shell file lets us skip running autoconf when modifying
# build-, host- and target-specific information.

# This file switches on the shell variable ${machine}, and also uses the
# following shell variables:
#
#  with_*               Various variables as set by configure.
#
#  enable_threads_flag  Either the name, yes or no depending on whether
#                       threads support was requested.
#
#  gas_flag             Either yes or no depending on whether GNU as was
#                       requested.
#
#  gnu_ld_flag          Either yes or no depending on whether GNU ld was
#                       requested.

# This file sets the following shell variables for use by the
# autoconf-generated configure script:

#
#  tm_file              A list of target macro files, if different from

#                       include, like "vax" for "float-vax.h".  If no such

#
#  extra_objs           List of extra objects that should be linked into
