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}.
58 #
59 #  tm_p_file            Location of file with declarations for functions
60 #                       in $out_file.

63 #                       file, if different from "$cpu_type/$cpu_type.c".
64 #
65 #  md_file              The name of the machine-description file, if
66 #                       different from "$cpu_type/$cpu_type.md".
67 #
68 #  tmake_file           A list of machine-description-specific
69 #                       makefile-fragments, if different from
70 #                       "$cpu_type/t-$cpu_type".

72 #  float_format         Set to the symbolic name for the floating-point
73 #                       formats used for this machine, if different from
74 #                       "i64".  Used to derive a header file name to
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)
80 #                       depending on target.
81 #
