680 | # There should be an assembly language file named FILE.s in the test | |
681 | # suite directory, and a pattern file called FILE.d. run_dump_test | |
682 | # will assemble FILE.s, optionally run objcopy on the object file, | |
683 | # optionally run ld, optionally run another objcopy, optionally run | |
684 | # another tool under test specified by PROG, then run a dump tool like | |
685 | # addr2line, nm, objdump, readelf or size on the object file to produce | |
686 | # textual output, and then analyze that with regexps. | |
687 | # The FILE.d file specifies what program to run, and what to expect in | |
688 | # its output. | |
689 | # | |
690 | # The FILE.d file begins with zero or more option lines, which specify | |
691 | # flags to pass to the assembler, the program to run to dump the | |
692 | # assembler's output, and the options it wants. The option lines have | |
693 | # the syntax: | |
694 | # | |
695 | # # OPTION: VALUE | |
696 | # | |
697 | # OPTION is the name of some option, like "name" or "objdump", and | |
698 | # VALUE is OPTION's value. The valid options are described below. | |
699 | # Whitespace is ignored everywhere, except within VALUE. The option | |
700 | # list ends with the first line that doesn't match the above syntax. | |
701 | # However, a line within the options that begins with a #, but doesn't | |
702 | # have a recognizable option name followed by a colon, is considered a | |
703 | # comment and entirely ignored. | |
704 | # | |
705 | # The optional EXTRA_OPTIONS argument to `run_dump_test' is a list of | |
706 | # two-element lists. The first element of each is an option name, and | |
707 | # the second additional arguments to be added on to the end of the | |
708 | # option list as given in FILE.d. (If omitted, no additional options | |
709 | # are added.) | |
710 | # | |
711 | # The interesting options are: | |
712 | # | |
713 | # name: TEST-NAME | |
714 | # The name of this test, passed to DejaGNU's `pass' and `fail' | |
715 | # commands. If omitted, this defaults to FILE, the root of the | |
716 | # .s and .d files' names. | |

718 | # as: FLAGS | |

722 | # Multiple instances of this directive tells run_dump_test to run the test |
723 | # multiple times -- one time with each set of flags provided. | |
724 | # Each instance will run exactly as a file with a single "as" line, it is | |
725 | # not possible to condition any behaviour on which set of "as" flags is | |
726 | # used. That means that the "source" specific options are appended to | |
727 | # the "as" flags for their corresponding files, and any extra processing | |

772 | # DUMPPROG: [nm objdump readelf addr2line] | |
773 | # instead, or just pass a flag that happens to be the default. | |
774 | # If objdump is the dump tool and we're not dumping binary, nor | |
775 | # have run ld, then the standard section names (.text, .data and | |
776 | # .bss) are replaced by target ones if any (eg. rx-elf uses "P" | |
777 | # instead of .text). The substition is done for both the | |

781 | # source: SOURCE [FLAGS] | |
