-- We only support SparcV9 and better because V8 lacks an atomic CAS
-- instruction so we have to make sure that the assembler accepts the
-- instruction set. Note that the user can still override this
-- (e.g., -mcpu=ultrasparc). GCC picks the "best" -mcpu flag
-- regardless of the ordering.

-- This is a temporary hack.
