  22 # This is the libgcc host-specific configuration file
  23 # where a configuration type is mapped to different system-specific
  24 # definitions and files.  This is invoked by the autoconf-generated
  25 # configure script.  Putting it in a separate shell file lets us skip
  26 # running autoconf when modifying host-specific information.
  27
  28 # This file bears an obvious resemblance to gcc/config.gcc.  The cases
  29 # should be kept similar, to ease moving library-specific settings
  30 # from config.gcc to this file.  That is also why tmake_file is
  31 # left as tmake_file, rather than hmake_file, even though this library
  32 # switches on ${host}.
  33
  34 # This file switches on the shell variable ${host}, and also uses the
  35 # following shell variables:
  36 #
  37 #  with_*               Various variables as set by configure.
  38
  39 # This file sets the following shell variables for use by the
  40 # autoconf-generated configure script:
  41 #
  42 #  asm_hidden_op        The assembler pseudo-op to use for hide
  43 #                       lists for object files implemented in
  44 #                       assembly (with -fvisibility=hidden for C).
  45 #                       The default is ".hidden".
  46 #  cpu_type             The name of the cpu, if different from the first
  47 #                       chunk of the canonical host name.
  48 #  extra_parts          List of extra object files that should be compiled
  49 #                       for this target machine.  This may be overridden
  50 #                       by setting EXTRA_PARTS in a tmake_file fragment.
  51 #                       If either is set, EXTRA_PARTS and
  52 #                       EXTRA_MULTILIB_PARTS inherited from the GCC
  53 #                       subdirectory will be ignored.
  54 #  tmake_file           A list of machine-description-specific
  55 #                       makefile-fragments, if different from
  56 #                       "$cpu_type/t-$cpu_type".
