  22 # This is the GCC build-, host- and target-specific configuration file
  23 # where a configuration type, as recognized and generated by config.bfd,
  24 # is mapped to different system-specific definitions and files.  This is
  25 # invoked by the autoconf-generated configure script, called for build,
  26 # host and target in that order, setting ${machine} to each.  Putting it
  27 # in a separate shell file lets us skip running autoconf when modifying
  28 # build-, host- and target-specific information.
  29
  30 # This file switches on the shell variable ${machine}, and also uses the
  31 # following shell variables:
  32 #
  33 #  with_*               Various variables as set by configure.
  34 #
  35 #  enable_threads_flag  Either the name, yes or no depending on whether
  36 #                       threads support was requested.
  37 #
  38 #  gas_flag             Either yes or no depending on whether GNU as was
  39 #                       requested.
  40 #
  41 #  gnu_ld_flag          Either yes or no depending on whether GNU ld was
  42 #                       requested.
  43
  44 # This file sets the following shell variables for use by the
  45 # autoconf-generated configure script:
  46 #
  47 #  cpu_type             The name of the cpu, if different from machine.

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