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

  70 #
  71 #  tm_file              A list of target macro files, if different from
  72 #                       "$cpu_type/$cpu_type.h". Usually it's constructed
  73 #                       per target in a way like this:
  74 #                       tm_file="${tm_file} dbxelf.h elfos.h ${cpu_type.h}/elf.h"
  75 #                       Note that the preferred order is:
  76 #                       - specific target header "${cpu_type}/${cpu_type.h}"
  77 #                       - generic headers like dbxelf.h elfos.h, etc.
  78 #                       - specializing target headers like ${cpu_type.h}/elf.h
  79 #                       This helps to keep OS specific stuff out of the CPU
  80 #                       defining header ${cpu_type}/${cpu_type.h}.
  81 #
  82 #                       It is possible to include automatically-generated
  83 #                       build-directory files by prefixing them with "./".
  84 #                       All other files should relative to $srcdir/config.

 102 #                       makefile-fragments, if different from
 103 #                       "$cpu_type/t-$cpu_type".
 104 #
 105 #  extra_modes          The name of the file containing a list of extra
 106 #                       machine modes, if necessary and different from

 108 #
 109 #  extra_objs           List of extra objects that should be linked into

 112 #
