# 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
# This file switches on the shell variable ${target}, and also uses the
28
# following shell variables:
29
#
30
#  with_*               Various variables as set by configure.
31
#
32
#  enable_threads       Either the name, yes or no depending on whether
33
#                       threads support was requested.
34
#
35
#  default_use_cxa_atexit
36
#                         The default value for the $enable___cxa_atexit
37
#                       variable.  enable___cxa_atexit needs to be set to
38
#                       "yes" for the correct operation of C++ destructors
39
#                       but it relies upon the presence of a non-standard C
40
#                       library function called __cxa_atexit.
41
#                         Since not all C libraries provide __cxa_atexit the
42
#                       default value of $default_use_cxa_atexit is set to
43
#                       "no" except for targets which are known to be OK.
44
#
45
#  gas_flag             Either yes or no depending on whether GNU as was
46
#                       requested.
47
#
48
#  gnu_ld_flag          Either yes or no depending on whether GNU ld was
49
#                       requested.
50
 
51
# This file sets the following shell variables for use by the
52
# autoconf-generated configure script:
53
#
54
#  cpu_type             The name of the cpu, if different from the first
55
#                       chunk of the canonical target name.
56
#
57
#  tm_defines           List of target macros to define for all compilations.
58
#
59
#  tm_file              A list of target macro files, if different from
60
#                       "$cpu_type/$cpu_type.h". Usually it's constructed
61
#                       per target in a way like this:
62
#                       tm_file="${tm_file} dbxelf.h elfos.h svr4.h ${cpu_type.h}/elf.h"
63
#                       Note that the preferred order is:
64
#                       - specific target header "${cpu_type}/${cpu_type.h}"
65
#                       - generic headers like dbxelf.h elfos.h, etc.
66
#                       - specializing target headers like ${cpu_type.h}/elf.h
67
#                       This helps to keep OS specific stuff out of the CPU
68
#                       defining header ${cpu_type}/${cpu_type.h}.
69
#
70
#  tm_p_file            Location of file with declarations for functions
71
#                       in $out_file.
72
#
73
#  out_file             The name of the machine description C support
74
#                       file, if different from "$cpu_type/$cpu_type.c".
75
#
76
#  md_file              The name of the machine-description file, if
77
#                       different from "$cpu_type/$cpu_type.md".
78
#
79
#  tmake_file           A list of machine-description-specific
80
#                       makefile-fragments, if different from
81
#                       "$cpu_type/t-$cpu_type".
82
#
83
#  extra_modes          The name of the file containing a list of extra
84
#                       machine modes, if necessary and different from
85
#                       "$cpu_type/$cpu_type-modes.def".
86
#
87
#  extra_objs           List of extra objects that should be linked into
88
#                       the compiler proper (cc1, cc1obj, cc1plus)
89
#                       depending on target.
90
#
91

98

99
#
100
#  extra_parts          List of extra object files that should be compiled
101
#                       for this target machine.
102
#
103
#  extra_programs       Like extra_passes, but these are used when linking.
104
