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 #  default_use_cxa_atexit
39 #                       "no" by default, can be set to "yes" if a target
40 #                       wishes to use __cxa_atexit() by default if the
41 #                       $enable___cxa_atexit variable is not set.
42 #
43 #  gas_flag             Either yes or no depending on whether GNU as was
44 #                       requested.
45 #
46 #  gnu_ld_flag          Either yes or no depending on whether GNU ld was
47 #                       requested.
48
49 # This file sets the following shell variables for use by the
50 # autoconf-generated configure script:
51 #
52 #  cpu_type             The name of the cpu, if different from machine.
53 #

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

87 #
