17 # A MIPS version of the GCC dg.exp driver.
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.
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
28 # { dg-options "-mips1" }
30 # and the user passes the following option to runtest:
32 # --target_board unix/-mips3
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
:
38 #
{ dg
-do compile { target can_force_mips1
} }
40 # so that the test is skipped when an option like
-mips3 is passed.
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
:
47 #
--target_board unix
{-mabi
=n32
,-mabi
=32,-mabi
=64}
49 # when testing them. But these
-mabi
=* options would normally prevent
any
50 # EABI and o64 tests from running.
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.
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
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.
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.
)
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.
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:
88 # dg-options "-mips3d -mpaired-single -mhard-float -mgp64 -mfp64 -mabi=n32 -march=mips64 -mips64"
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
95 # - It is easy to forget options.
97 # - If a new option is added, all tests that are incompatible with that
98 # option must be updated.
100 # - We want to be able to test MIPS-3D with things like -march=mips32,
101 # -march=mips64r2, -march=sb1, and so on.
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.
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.
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.
120 #
{ dg
-options
"(-mips16)" }
122 # selects a MIPS16
-compatible target without passing
-mips16 itself.
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
:
127 # PROP
=VALUE PROP
<=VALUE PROP
>=VALUE
132 # the value of the __mips macro.
135 # the value of the __mips_isa_rev macro
, or
0 if it isn
't defined.
137 # For example, "isa_rev>=1" selects a MIPS32 or MIPS64 processor,
138 # "isa=4" selects a MIPS IV processor, and so on.
140 # There are also the following special pseudo-options:
143 # select a Loongson processor
145 # addressing=absolute
146 # force absolute addresses to be used
149 # forbid processors that match the given regexp; choose a
150 # generic ISA instead.
155 # (1) Try to avoid { target ... } requirements wherever possible.
156 # Specify the requirements as dg-options instead.
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.
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
,
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.
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".
182 # (6) If you need to disable processor-specific extensions use
183 # forbid_cpu=REGEXP instead of forcing a generic ISA.
