| # Copied from gas testsuite, tweaked and further extended. |
| # |
| # Assemble a .s file, then run some utility on it and check the output. |
| # |
| # There should be an assembly language file named FILE.s in the test |
| # suite directory, and a pattern file called FILE.d. `run_dump_test' |
| # will assemble FILE.s, run some tool like `objdump', `objcopy', or |
| # `nm' on the .o file to produce textual output, and then analyze that |
| # with regexps. The FILE.d file specifies what program to run, and |
| # what to expect in its output. |
| # |
| # The FILE.d file begins with zero or more option lines, which specify |
| # flags to pass to the assembler, the program to run to dump the |
| # assembler's output, and the options it wants. The option lines have |
| # the syntax: |
| # |
| # # OPTION: VALUE |
| # |
| # OPTION is the name of some option, like "name" or "objdump", and |
| # VALUE is OPTION's value. The valid options are described below. |
| # Whitespace is ignored everywhere, except within VALUE. The option |
| # list ends with the first line that doesn't match the above syntax |
| # (hmm, not great for error detection). |
| # |
| # The optional EXTRA_OPTIONS argument to `run_dump_test' is a list of |
| # two-element lists. The first element of each is an option name, and |
| # the second additional arguments to be added on to the end of the |
| # option list as given in FILE.d. (If omitted, no additional options |
| # are added.) |
| # |
| # The interesting options are: |
| # |
| # name: TEST-NAME |
| # The name of this test, passed to DejaGNU's `pass' and `fail' |
| # commands. If omitted, this defaults to FILE, the root of the |
| # .s and .d files' names. |
| # |
| # as: FLAGS |
| # When assembling, pass FLAGS to the assembler. |
| # If assembling several files, you can pass different assembler |
| # options in the "source" directives. See below. |
| # |
| # ld: FLAGS |
| # Link assembled files using FLAGS, in the order of the "source" |
| # directives, when using multiple files. |
| # |
| # ld_after_inputfiles: FLAGS |
| # Similar to "ld", but put after all input files. |
| # |
| # objcopy_objects: FLAGS |
| # Run objcopy with the specified flags after assembling any source |
| # that has the special marker RUN_OBJCOPY in the source specific |
| # flags. |
| # |
| # objcopy_linked_file: FLAGS |
| # Run objcopy on the linked file with the specified flags. |
| # This lets you transform the linked file using objcopy, before the |
| # result is analyzed by an analyzer program specified below (which |
| # may in turn *also* be objcopy). |
| # |
| # PROG: PROGRAM-NAME |
| # The name of the program to run to analyze the .o file produced |
| # by the assembler or the linker output. This can be omitted; |
| # run_dump_test will guess which program to run by seeing which of |
| # the flags options below is present. |
| # |
| # readelf: FLAGS |
| # objdump: FLAGS |
| # nm: FLAGS |
| # objcopy: FLAGS |
| # Use the specified program to analyze the assembler or linker |
| # output file, and pass it FLAGS, in addition to the output name. |
| # Note that they are run with LC_ALL=C in the environment to give |
| # consistent sorting of symbols. |
| # |
| # source: SOURCE [FLAGS] |
| # Assemble the file SOURCE.s using the flags in the "as" directive |
| # and the (optional) FLAGS. If omitted, the source defaults to |
| # FILE.s. |
| # This is useful if several .d files want to share a .s file. |
| # More than one "source" directive can be given, which is useful |
| # when testing linking. |
| # |
| # dump: DUMP |
| # Match against DUMP.d. If omitted, this defaults to FILE.d. This |
| # is useful if several .d files differ by options only. Options are |
| # always read from FILE.d. |
| # |
| # xfail: TARGET |
| # The test is expected to fail on TARGET. This may occur more than |
| # once. |
| # |
| # target: TARGET |
| # Only run the test for TARGET. This may occur more than once; the |
| # target being tested must match at least one. You may provide target |
| # name "cfi" for any target supporting the CFI statements. |
| # |
| # notarget: TARGET |
| # Do not run the test for TARGET. This may occur more than once; |
| # the target being tested must not match any of them. |
| # |
| # error: REGEX |
| # An error with message matching REGEX must be emitted for the test |
| # to pass. The PROG, readelf, objdump, nm and objcopy options have |
| # no meaning and need not be supplied if this is present. Multiple |
| # "error" directives append to the expected linker error message. |
| # |
| # error_output: FILE |
| # Means the same as 'error', except the regular expression lines |
| # are contains in FILE. |
| # |
| # warning: REGEX |
| # Expect a linker warning matching REGEX. It is an error to issue |
| # both "error" and "warning". Multiple "warning" directives |
| # append to the expected linker warning message. |
| # |
| # warning_output: FILE |
| # Means the same as 'warning', except the regular expression |
| # lines are contains in FILE. |
| # |
| # map: FILE |
| # Adding this option will cause the linker to generate a linker |
| # map file, using the -Map=MAPFILE command line option. If |
| # there is no -Map=MAPFILE in the 'ld: FLAGS' then one will be |
| # added to the linker command line. The contents of the |
| # generated MAPFILE are then compared against the regexp lines |
| # in FILE using `regexp_diff' (see below for details). |
| # |
| # Each option may occur at most once unless otherwise mentioned. |
| # |
| # After the option lines come regexp lines. `run_dump_test' calls |
| # `regexp_diff' to compare the output of the dumping tool against the |
| # regexps in FILE.d. `regexp_diff' is defined in binutils-common.exp; |
| # see further comments there. |
