  21 # This is the GCC target-specific configuration file
  22 # where a configuration type is mapped to different system-specific
  23 # definitions and files.  This is invoked by the autoconf-generated
  24 # configure script.  Putting it in a separate shell file lets us skip
  25 # running autoconf when modifying target-specific information.
  26
  27 # When you change the cases in the OS or target switches, consider
  28 # updating ../libgcc/config.host also.
  29
  30 # This file switches on the shell variable ${target}, and also uses the
  31 # following shell variables:
  32 #
  33 #  with_*               Various variables as set by configure.
  34 #
  35 #  enable_threads       Either the name, yes or no depending on whether
  36 #                       threads support was requested.
  37 #
  38 #  default_use_cxa_atexit
  39 #                         The default value for the $enable___cxa_atexit
  40 #                       variable.  enable___cxa_atexit needs to be set to
  41 #                       "yes" for the correct operation of C++ destructors
  42 #                       but it relies upon the presence of a non-standard C
  43 #                       library function called __cxa_atexit.
  44 #                         Since not all C libraries provide __cxa_atexit the
  45 #                       default value of $default_use_cxa_atexit is set to
  46 #                       "no" except for targets which are known to be OK.
  47 #
  48 #  default_gnu_indirect_function
  49 #                       The default value for the $enable_gnu_indirect_function
  50 #                       variable.  enable_gnu_indirect_function relies
  51 #                       upon the presence of a non-standard gnu ifunc support
  52 #                       in the assembler, linker and dynamic linker.
  53 #                       Since not all libraries provide the dynamic linking
  54 #                       support, the default value of
  55 #                       $default_gnu_indirect_function is set to
  56 #                       "no" except for targets which are known to be OK.
  57 #
  58 #  gas_flag             Either yes or no depending on whether GNU as was
  59 #                       requested.
  60 #
  61 #  gnu_ld_flag          Either yes or no depending on whether GNU ld was
  62 #                       requested.
  63
  64 # This file sets the following shell variables for use by the
  65 # autoconf-generated configure script:
  66 #
  67 #  cpu_type             The name of the cpu, if different from the first
  68 #                       chunk of the canonical target name.

  71 #
  72 #  tm_file              A list of target macro files, if different from
  73 #                       "$cpu_type/$cpu_type.h". Usually it's constructed
  74 #                       per target in a way like this:
  75 #                       tm_file="${tm_file} dbxelf.h elfos.h ${cpu_type.h}/elf.h"
  76 #                       Note that the preferred order is:
  77 #                       - specific target header "${cpu_type}/${cpu_type.h}"
  78 #                       - generic headers like dbxelf.h elfos.h, etc.
  79 #                       - specializing target headers like ${cpu_type.h}/elf.h
  80 #                       This helps to keep OS specific stuff out of the CPU
  81 #                       defining header ${cpu_type}/${cpu_type.h}.
  82 #
  83 #                       It is possible to include automatically-generated
  84 #                       build-directory files by prefixing them with "./".

  86 #
  87 #  libgcc_tm_file       A list of target macro files used only for code

  89 #                       are relative to $srcdir/../libgcc/config and
  90 #                       must not have the same names as files in
  91 #                       $srcdir/config.
  92 #
  93 #  tm_p_file            Location of file with declarations for functions

  95 #

 100 #                       the compiler proper and the driver.
 101 #
 102 #  md_file              The name of the machine-description file, if
 103 #                       different from "$cpu_type/$cpu_type.md".
 104 #
 105 #  tmake_file           A list of machine-description-specific
 106 #                       makefile-fragments, if different from
 107 #                       "$cpu_type/t-$cpu_type".
 108 #
 109 #  extra_modes          The name of the file containing a list of extra
 110 #                       machine modes, if necessary and different from
 111 #                       "$cpu_type/$cpu_type-modes.def".
 112 #
 113 #  extra_objs           List of extra objects that should be linked into
 114 #                       the compiler proper (cc1, cc1obj, cc1plus)

 116 #
