The FILE.d file specifies what program to run, and 327 # what to expect in its output. 328 # 329 # The FILE.d file begins with zero or more option lines, which specify 330 # flags to pass to the assembler, the program to run to dump the 331 # assembler's output, and the options it wants.

If no FLAGS are needed then use: 369 # PROG: [nm objcopy objdump readelf addr2line] 370 # instead. 371 # Note: for objdump, we automatically replaces the standard section 372 # names (.text, .data and .bss) by target ones if any (eg. rx-elf 373 # uses "P" instead of .text). The substition is done for both 374 # the objdump options (eg: "-j .text" is replaced by "-j P") and the 375 # reference file. 376 # 377 # source: SOURCE 378 # Assemble the file SOURCE.s. If omitted, this defaults to FILE.s. 379 # This is useful if several .d files want to share a .s file. 380 # 381 # dump: DUMP 382 # Match against DUMP.d. If omitted, this defaults to FILE.d.

Again, 394 # the each glob in the space-separated list is passed to 395 # "istarget", and the test is run if it evaluates *false* for 396 # *all* of them.
