615 # .o file produced by the assembler. Recognised names are: ar,
616 # elfedit, nm, objcopy, ranlib, strings, and strip.
618 # DUMPPROG: PROGRAM-NAME
619 # The name of the program to run to analyze the file produced
620 # by the assembler or the linker. This can be omitted;
621 # run_dump_test will guess which program to run from which of
622 # the flags options below is present.

634 # instead, or just pass a flag that happens to be the default.
635 # If objdump is the dump tool and we're not dumping binary, nor
636 # have run ld, then the standard section names (.text, .data and
