[ Sorry for the delay,  I was out for a couple of days.  Re-adding
binutils@sourceware.org (I meant to copy on my 2nd reply). ]

So without PROCESSOR_BDVER2, that means no -march=bdver2 flag support,
but what else?

What if -march/-mtune support is added to GCC for bdver2, how would it
convey -march=bdver2 to the assembler?
