17 | # A MIPS version of the GCC dg.exp driver. |
18 | # | |
19 | # There are many MIPS features that we want to test, and many of those | |
20 | # features are specific to certain architectures, certain ABIs and so on. | |
21 | # There are therefore many cases in which we want to test something that | |
22 | # is incompatible with the user's chosen test options. | |
23 | # | |
24 | # In most dg testsuites, the options added by dg-options have a lower | |
25 | # priority than the options chosen by the user. For example, if a test | |
26 | # specifies: | |
27 | # | |
28 | # { dg-options "-mips1" } | |
29 | # | |
30 | # and the user passes the following option to runtest: | |
31 | # | |
32 | # --target_board unix/-mips3 | |
33 | # | |
34 | # the test would be compiled as MIPS III rather than MIPS I. If the | |
35 | # test really wouldn't work with -mips3, normal practice would be to | |
36 | # have something like: | |
37 | # | |
38 | # { dg-do compile { target can_force_mips1 } } | |
39 | # | |
40 | # so that the test is skipped when an option like -mips3 is passed. | |
41 | # | |
42 | # Sticking to the same approach here would cause us to skip many tests, | |
43 | # even though the toolchain can generate the required code. For example, | |
44 | # there are 6 MIPS ABIs, plus variants. Some configurations support | |
45 | # more than one ABI, so it is natural to use something like: | |
46 | # | |
47 | # --target_board unix{-mabi=n32,-mabi=32,-mabi=64} | |
48 | # | |
49 | # when testing them. But these -mabi=* options would normally prevent any | |
50 | # EABI and o64 tests from running. | |
51 | # | |
52 | # This testsuite therefore defines a local version of dg-options that | |
53 | # overrides any user options that are incompatible with the test options. | |
54 | # It tries to keep the other user options intact. | |
55 | # | |
56 | # | |
57 | # Most of the tests in this testsuite are scan-assembler tests, but | |
58 | # sometimes we need a link test instead. In these cases, we must not | |
59 | # try to link code with options that are incompatible with the current | |
60 | # multilib, because xgcc is passed -L and -B options that are specific | |
61 | # to that multilib. | |
62 | # | |
63 | # Normal GCC practice would be to skip incompatible link tests as | |
64 | # unsupported, but in this particular case, it seems better to downgrade | |
65 | # them to an assemble test instead. At least that way we get some | |
66 | # test-for-ICE and code-sanity coverage. | |
67 | # | |
68 | # The same problem applies to run tests. If a test requires runtime | |
69 | # support for a particular feature, and if the current target does not | |
70 | # provide that support, normal practice would be to skip the test. | |
71 | # But in this case it seems better to downgrade it to a link test instead. | |
72 | # (We might then have to downgrade it to an assembler test according to | |
73 | # the constraints just mentioned.) | |
74 | # | |
75 | # The local dg-options therefore checks whether the new options are | |
76 | # link-compatiable with the user's options. If not, it automatically | |
77 | # downgrades link tests to assemble tests. It does the same for run | |
78 | # tests, but in addition, it downgrades run tests to link tests if the | |
79 | # target does not provide runtime support for a required feature or ASE. | |
80 | # | |
81 | # | |
82 | # Another problem is that many of the options we want to test require | |
83 | # certain other features. For example, -mips3d requires both 64-bit | |
84 | # FPRs and a MIPS32 or MIPS64 target; -mfix-r10000 requires branch- | |
85 | # likely instructions; and so on. We could handle this by specifying | |
86 | # a set of options that are guaranteed to give us what we want, such as: | |
87 | # | |
88 | # dg-options "-mips3d -mpaired-single -mhard-float -mgp64 -mfp64 -mabi=n32 -march=mips64 -mips64" | |
89 | # | |
90 | # With the new dg-options semantics, this would override any troublesome | |
91 | # user options like -mips3, -march=vr4100, -mfp32, -mgp32, -msoft-float, | |
92 | # -mno-paired-single and so on. But there are three major problems with | |
93 | # this: | |
94 | # | |
95 | # - It is easy to forget options. | |
96 | # | |
97 | # - If a new option is added, all tests that are incompatible with that | |
98 | # option must be updated. | |
99 | # | |
100 | # - We want to be able to test MIPS-3D with things like -march=mips32, | |
101 | # -march=mips64r2, -march=sb1, and so on. | |
102 | # | |
103 | # The local version of dg-options therefore works out the requirements | |
104 | # of each test option. As with the test options themselves, the local | |
105 | # dg-options overrides any user options that incompatible with these | |
106 | # requirements, but it keeps the other user options the same. | |
107 | # | |
108 | # For example, if the user passes -mips3, a MIPS-3D test will choose | |
109 | # a different architecture like -mips64 instead. But if the user | |
110 | # passes -march=sb1, MIPS-3D tests will be run with that option. | |
111 | # | |
112 | # | |
113 | # Sometimes it is useful to say "I want an environment that is compatible | |
114 | # with option X, but I don't want to pass option X itself". The main example | |
115 | # of this is -mips16: we want to be able to test __attribute__((mips16)) | |
116 | # without requiring the test itself to be compiled as -mips16. The local | |
117 | # version of dg-options lets you do this by putting X in parentheses. | |
118 | # For example: | |
119 | # | |
120 | # { dg-options "(-mips16)" } | |
121 | # | |
122 | # selects a MIPS16-compatible target without passing -mips16 itself. | |
123 | # | |
124 | # It is also useful to say "any architecture within this ISA range is fine". | |
125 | # This can be done using special pseudo-options of the form: | |
126 | # | |
127 | # PROP=VALUE PROP<=VALUE PROP>=VALUE | |
128 | # | |
129 | # where PROP can be: | |
130 | # | |
131 | # isa: | |
132 | # the value of the __mips macro. | |
133 | # | |
134 | # isa_rev: | |
135 | # the value of the __mips_isa_rev macro, or 0 if it isn't defined. | |
136 | # | |
137 | # For example, "isa_rev>=1" selects a MIPS32 or MIPS64 processor, | |
bde8c97c | 138 | # "isa=4" selects a MIPS IV processor, and so on. |
c05854ec | 139 | # |
bde8c97c AN |
140 | # There are also the following special pseudo-options: |
141 | # | |
142 | # isa=loongson | |
c05854ec RS |
143 | # select a Loongson processor |
144 | # | |
145 | # addressing=absolute | |
146 | # force absolute addresses to be used | |
147 | # | |
631c905a AN |
148 | # forbid_cpu=REGEXP |
149 | # forbid processors that match the given regexp; choose a | |
150 | # generic ISA instead. | |
151 | # | |
c05854ec RS |
152 | # |
153 | # In summary: | |
154 | # | |
155 | # (1) Try to avoid { target ... } requirements wherever possible. | |
156 | # Specify the requirements as dg-options instead. | |
157 | # | |
158 | # (2) Don't worry about the consequences of (1) for link and run tests. | |
159 | # If the test uses { dg-do link } or { dg-do run }, and its | |
160 | # dg-options are incompatible with the current target, the | |
161 | # testsuite will downgrade them where necessary. | |
162 | # | |
163 | # (3) Try to use the bare minimum of options and leave dg-options | |
164 | # to work out the dependencies. For example, if you want | |
165 | # a MIPS-3D test, you should generally just specify -mips3d. | |
166 | # Don't specify an architecture option like -mips64 unless | |
167 | # the test really doesn't work with -mips32r2, -mips64r2, | |
168 | # -march=sb1, etc. | |
169 | # | |
170 | # (4) If you want something compatible with a particular option, | |
171 | # but don't want to pass the option itself, wrap that option | |
172 | # in parentheses. In particular, pass '(-mips16)' if you | |
173 | # want to use "mips16" attributes. | |
174 | # | |
175 | # (5) When testing a feature of a generic ISA (as opposed to a | |
176 | # processor-specific extension), try to use the "isa" and | |
177 | # "isa_rev" pseudo-options instead of specific architecture | |
178 | # options. For example, if the feature is present on revision 2 | |
179 | # processors and above, try to use "isa_rev>=2" instead of | |
180 | # "-mips32r2" or "-mips64r2". | |
bde8c97c AN |
181 | # |
182 | # (6) If you need to disable processor-specific extensions use | |
631c905a | 183 | # forbid_cpu=REGEXP instead of forcing a generic ISA. |

198 | # not explicit and can be omitted depending on the base options. | |
199 | # | |
200 | # Base options: | |
201 | # Options that are on by default without being specified in dg-options, | |
202 | # e.g. -march=mips64r2 for mipsisa64r2-elf or because they've been | |

210 | # option that is in effect from this group. If no option is active it | |
211 | # contains the empty string. The flags "explicit_p" and "test_option_p" | |
212 | # are set for explicit and test options. | |
