armv6. It's too ambiguous. We do use the softfp ABI for the moment on armv6, but we allow floating point register use (and the compilers will generate it). This is too ambiguous to use it as a decider for which algorithms to use on the platform. Err on the side of caution and not define it. Submitted by: ian@ Reviewed by: andrew@
