Agreed. In that case we simply emit the data all the time and let capable debuggers pick it up. > If the assembler and linker generate errors, it further > delays deployment in GCC. If the assembler generates errors, then surely it's easy to error out at configure time, printing a note about the service pack. So, assuming this is true, when configuring for aix7.1, * configure --without-dwarf2 disables support for dwarf2 entirely, avoiding problems with any missing SP. Presumably by *not* including config/rs6000/aix71.h. * configure checks as/ld as required, erroring out if the SP isn't present; dwarf2out always emits all of the usual dwarf data. Sound good? r~
