| # run_dump_test FILE |
| # 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 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. |
| # |
| # 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. |
| # |
| # 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. |
| # |
| # 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. |
| # |
| # 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, objdump, nm and objcopy options have no |
| # meaning and need not supplied if this is present. |
| # |
| # 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 later in this file; see |
| # further comments there. |
