| # run_dump_test FILE (optional:) EXTRA_OPTIONS |
| # |
| # 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 FILE.s, pass FLAGS to the assembler. |
| # |
| # PROG: PROGRAM-NAME |
| # The name of the program to run to analyze the .o file produced |
| # by the assembler. This can be omitted; run_dump_test will guess |
| # which program to run by seeing which of the flags options below |
| # is present. |
| # |
| # objdump: FLAGS |
| # nm: FLAGS |
| # objcopy: FLAGS |
| # Use the specified program to analyze the .o file, and pass it |
| # FLAGS, in addition to the .o file name. Note that they are run |
| # with LC_ALL=C in the environment to give consistent sorting |
| # of symbols. |
| # |
| # source: SOURCE |
| # Assemble the file SOURCE.s. If omitted, this defaults to FILE.s. |
| # This is useful if several .d files want to share a .s file. |
| # |
| # error: REGEX |
| # An error with message matching REGEX must be emitted for the test |
| # to pass. The PROG, objdump, nm and objcopy options have no |
| # meaning and need not supplied if this is present. |
| # |
| # warning: REGEX |
| # Expect a gas warning matching REGEX. It is an error to issue |
| # both "error" and "warning". |
| # |
| # Each option may occur at most once. |
| # |
| # 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 later in this file; see |
| # further comments there. |
