21 # This shell script produces a header file which the gcc driver
|
|
|
22 # program uses to pick which library to use based on the machine
|
|
|
23 # specific options that it is given.
|
|
|
24
|
|
|
25 # The first argument is a list of sets of options. The elements in
|
|
|
26 # the list are separated by spaces. Within an element, the options
|
|
|
27 # are separated by slashes or pipes. No leading dash is used on the
|
|
|
28 # options.
|
|
|
29 # Each option in a set separated by slashes is mutually incompatible
|
|
|
30 # with all other options
|
|
|
31 # in the set.
|
|
|
32 # Each option in a set separated by pipes will be used for the library
|
|
|
33 # compilation and any of the options in the set will be sufficient
|
|
|
34 # for it to be triggered.
|
|
|
35
|
|
|
36 # The optional second argument is a list of subdirectory names. If
|
|
|
37 # the second argument is non-empty, there must be as many elements in
|
|
|
38 # the second argument as there are options in the first argument. The
|
|
|
39 # elements in the second list are separated by spaces. If the second
|
|
|
40 # argument is empty, the option names will be used as the directory
|
|
|
41 # names.
|
|
|
42
|
|
|
43 # The optional third argument is a list of options which are
|
|
|
44 # identical. The elements in the list are separated by spaces. Each
|
|
|
45 # element must be of the form OPTION=OPTION. The first OPTION should
|
|
|
46 # appear in the first argument, and the second should be a synonym for
|
|
|
47 # it. Question marks are replaced with equal signs in both options.
|
|
|
48
|
|
|
49 # The optional fourth argument is a list of multilib directory
|
|
|
50 # combinations that should not be built.
|
|
|
51
|
|
|
52 # The optional fifth argument is a list of options that should be
|
|
|
53 # used whenever building multilib libraries.
|
|
|
54
|
|
|
55 # The optional sixth argument is a list of exclusions used internally by
|
|
|
56 # the compiler similar to exceptions. The difference being that exclusions
|
|
|
57 # allow matching default options that genmultilib does not know about and
|
|
|
58 # is done at runtime as opposed to being sorted out at compile time.
|
|
|
59 # Each element in the list is a separate exclusion rule. Each rule is
|
|
|
60 # a list of options (sans preceding '-') separated by a '/'. The options
|
|
|
61 # on the rule are grouped as an AND operation, and all options much match
|
|
|
62 # for the rule to exclude a set. Options can be preceded with a '!' to
|
|
|
63 # match a logical NOT.
|
|
|
64
|
|
|
65 # The optional seventh argument is a list of OS subdirectory names.
|
|
|
66 # The format is either the same as of the second argument, or a set of
|
|
|
67 # mappings. When it is the same as the second argument, it describes
|
|
|
68 # the multilib directories using OS conventions, rather than GCC
|
|
|
69 # conventions. When it is a set of mappings of the form gccdir=osdir,
|
|
|
70 # the left side gives the GCC convention and the right gives the
|
|
|
71 # equivalent OS defined location. If the osdir part begins with a !,
|
|
|
72 # the os directory names are used exclusively. Use the mapping when
|
|
|
73 # there is no one-to-one equivalence between GCC levels and the OS.
|

|
74
|
|
111
|
75 # The optional eighth argument which intends to reduce the effort to write
|
|
|
76 # so many MULTILIB_EXCEPTIONS rules. This option defines a series of option
|
|
|
77 # combinations that we actually required.
|
|
|
78 # For some cases, the generated option combinations are far more than what
|
|
|
79 # we need, we have to write a lot of rules to screen out combinations we
|
|
|
80 # don't need. If we missed some rules, the unexpected libraries will be built.
|
|
|
81 # Now with this argument, one can simply give what combinations are needed.
|
|
|
82 # It is pretty straigtforward.
|
|
|
83 # This argument can be used together with MULTILIB_EXCEPTIONS and will take
|
|
|
84 # effect after the MULTILIB_EXCEPTIONS.
|
|
|
85
|
|
|
86 # The optional ninth argument is the multiarch name.

89 # option sets.

99 # The SUBDIRECTORY is the subdirectory to use. The OPTIONS are

|
|
|
101 # exclamation point. gcc will consider each line in turn. If none of
|
|
|
102 # the options beginning with an exclamation point are present, and all

103 # of the other options are present, that subdirectory will be used.
|

|

105 # order; that is, a subdirectory is preceded by all its parents.

|
107 # Here is an example (this is from the actual sparc64 case):
|
|
|
108 # genmultilib 'm64/m32 mno-app-regs|mcmodel=medany' '64 32 alt'
|

109 # 'mcmodel?medany=mcmodel?medmid' 'm32/mno-app-regs* m32/mcmodel=*'

113 # ". !m64 !m32 !mno-app-regs !mcmodel=medany;",

115 # "32:../lib32 !m64 m32 !mno-app-regs !mcmodel=medany;",
