        (sparc32_frame_cache): For functions where there is no debugging

        function or not, fallback on checking whether the instruction
        at the return address is an "unimp" instruction or not.

  They should be correct now.

	neither imply SSE nor MMX. k6 implies MMX. k6_2 additionally implies
	3DNow!. Athlon additionally implies 3DNow!A. Several new
	entries (those starting with a dot are for sub-arch specification).
	(set_cpu_arch): Handle sub-arch specifications.
	(parse_insn): Distinguish between instructions not supported because
	of insufficient CPU features and because of 64-bit mode.

	* i386.h (i386_optab): paddq and psubq, even in their MMX form, are
	available only with SSE2. Change the MMX additions introduced by SSE
	and 3DNow!A to CpuMMX2 (rather than CpuMMX). Indicate the 3DNow!A
	instructions by their now designated identifier (since combining i686
	and 3DNow! does not really imply 3DNow!A).
