  22 # This is the GCC target-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 target-specific information.
  27
  28 # This file switches on the shell variable ${machine}, and also uses the
  29 # following shell variables:
  30 #
  31 #  with_*               Various variables as set by configure.
  32 #
  33 #  enable_threads_flag  Either the name, yes or no depending on whether
  34 #                       threads support was requested.
  35 #
  36 #  default_use_cxa_atexit
  37 #                       "no" by default, can be set to "yes" if a target
  38 #                       wishes to use __cxa_atexit() by default if the
  39 #                       $enable___cxa_atexit variable is not set.
  40 #
  41 #  gas_flag             Either yes or no depending on whether GNU as was
  42 #                       requested.
  43 #
  44 #  gnu_ld_flag          Either yes or no depending on whether GNU ld was
  45 #                       requested.
  46
  47 # This file sets the following shell variables for use by the
  48 # autoconf-generated configure script:
  49 #
  50 #  cpu_type             The name of the cpu, if different from machine.

  54 #  tm_file              A list of target macro files, if different from
  55 #                       "$cpu_type/$cpu_type.h". Usually it's constructed
  56 #                       per target in a way like this:
  57 #                       tm_file="${tm_file} dbxelf.h elfos.h svr4.h ${cpu_type.h}/elf.h"
  58 #                       Note that the preferred order is:
  59 #                       - specific target header "${cpu_type}/${cpu_type.h}"
  60 #                       - generic headers like dbxelf.h elfos.h, netware.h, etc.
  61 #                       - specializing target headers like ${cpu_type.h}/elf.h
  62 #                       This helps to keep OS specific stuff out of the CPU
  63 #                       defining header ${cpu_type}/${cpu_type.h}.
