  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 ${machine}, and also uses the
  30 # following shell variables:
  31 #
  32 #  with_*               Various variables as set by configure.
  33 #
  34 #  enable_threads_flag  Either the name, yes or no depending on whether
  35 #                       threads support was requested.
  36 #
  37 #  gas_flag             Either yes or no depending on whether GNU as was
  38 #                       requested.
  39 #
  40 #  gnu_ld_flag          Either yes or no depending on whether GNU ld was
  41 #                       requested.
  42
  43 # This file sets the following shell variables for use by the
  44 # autoconf-generated configure script:
  45 #
  46 #  cpu_type             The name of the cpu, if different from machine.
  47 #
  48 #  tm_file              A list of target macro files, if different from
  49 #                       "$cpu_type/$cpu_type.h". Usually it's constructed
  50 #                       per target in a way like this:
  51 #                       tm_file="${tm_file} elfos.h svr4.h ${cpu_type.h}/elf.h"
  52 #                       Note that the preferred order is:
  53 #                       - specific target header "${cpu_type}/${cpu_type.h}"
  54 #                       - generic headers like elfos.h, netware.h, etc.
  55 #                       - specializing target headers like ${cpu_type.h}/elf.h
  56 #                       This helps to keep OS specific stuff out of the CPU
  57 #                       defining header ${cpu_type}/${cpu_type.h}.

  73 #                       formats used for this machine, if different from

  75 #                       include, like "vax" for "float-vax.h".  If no such
  76 #                       file is wanted, set to "none".
  77 #
  78 #  extra_objs           List of extra objects that should be linked into
  79 #                       the compiler proper (cc1, cc1obj, cc1plus)
