21 # This is the GCC build-, host- and target-specific configuration file
22 # where a configuration type, as recognized and generated by config.bfd,
23 # is mapped to different system-specific definitions and files.  This is
24 # invoked by the autoconf-generated configure script, called for build,
25 # host and target in that order, setting ${machine} to each.  Putting it
26 # in a separate shell file lets us skip running autoconf when modifying
27 # build-, host- and target-specific information.
28
29 # This file switches on the shell variable ${machine}, and also uses the
30 # following shell variables:
31 #
32 #  with_*               Various variables as set by configure.
33 #
34 #  enable_threads_flag  Either the name, yes or no depending on whether
35 #                       threads support was requested.

38 #                       requested.

41 #                       requested.
