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 | |
699a42a6 JJ |
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 | |
08b28cd3 | 31 | # in the set. |
699a42a6 JJ |
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. | |
08b28cd3 DE |
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 | |
75814ad4 | 47 | # it. Question marks are replaced with equal signs in both options. |

49 | # The optional fourth argument is a list of multilib directory |
50 | # combinations that should not be built. | |
51 | ||
961b7009 MM |
52 | # The optional fifth argument is a list of options that should be |
53 | # used whenever building multilib libraries. | |
54 | ||
0a8d6618 BC |
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. | |
cc712abf JM |
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 | |
0a8d6618 BC |
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 | ||
55047c9d PE |
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. | |

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 | ||
e0cdc09f MK |
86 | # The optional ninth argument is the multiarch name. |
87 | ||
e7f49d92 TG |
88 | # The optional tenth argument specifies how to reuse multilib for different |
89 | # option sets. | |
90 | ||
c49d2df6 JJ |
91 | # The last option should be "yes" if multilibs are enabled. If it is not |
92 | # "yes", all GCC multilib dir names will be ".". | |
93 | ||
08b28cd3 DE |
94 | # The output looks like |
95 | # #define MULTILIB_MATCHES "\ | |
96 | # SUBDIRECTORY OPTIONS;\ | |
97 | # ... | |
98 | # " | |
99 | # The SUBDIRECTORY is the subdirectory to use. The OPTIONS are | |
100 | # multiple options separated by spaces. Each option may start with an | |
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. | |
104 | # The order of the subdirectories is such that they can be created in | |
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=*' | |
5bbcd587 | 110 | # '' 'm32/!m64/mno-app-regs m32/!m64/mcmodel=medany' |
e7f49d92 | 111 | # '../lib64 ../lib32 alt' '' '' '' yes |
08b28cd3 | 112 | # This produces: |
0a8d6618 | 113 | # ". !m64 !m32 !mno-app-regs !mcmodel=medany;", |
5bbcd587 JJ |
114 | # "64:../lib64 m64 !m32 !mno-app-regs !mcmodel=medany;", |
115 | # "32:../lib32 !m64 m32 !mno-app-regs !mcmodel=medany;", | |
0a8d6618 BC |
116 | # "alt !m64 !m32 mno-app-regs mcmodel=medany;", |
117 | # "alt !m64 !m32 mno-app-regs !mcmodel=medany;", | |
118 | # "alt !m64 !m32 !mno-app-regs mcmodel=medany;", | |
5bbcd587 JJ |
119 | # "64/alt:../lib64/alt m64 !m32 mno-app-regs mcmodel=medany;", |
120 | # "64/alt:../lib64/alt m64 !m32 mno-app-regs !mcmodel=medany;", | |
121 | # "64/alt:../lib64/alt m64 !m32 !mno-app-regs mcmodel=medany;", | |
87e24276 | 122 | # |
0a8d6618 BC |
123 | # The effect is that `gcc -mno-app-regs' (for example) will append "alt" |
124 | # to the directory name when searching for libraries or startup files and | |
125 | # `gcc -m32 -mcmodel=medany' (for example) will append "32/alt". Also note | |
126 | # that exclusion above is moot, unless the compiler had a default of -m32, | |
127 | # which would mean that all of the "alt" directories (not the 64/alt ones) | |
128 | # would be ignored (not generated, nor used) since the exclusion also | |
129 | # matches the multilib_default args. | |
