-The x86 directory is also the main support for P6 at the moment, and
-is something of a blended style, meant to be reasonable on all x86s.

-STATUS
-
-The code is well-optimized for AMD and Intel chips, but not so well
-optimized for Cyrix chips.

-RELEVANT OPTIMIZATION ISSUES
-
-For implementations with slow double shift instructions (SHLD and
-SHRD), it might be better to mimic their operation with SHL+SHR+OR.
-(M2 is likely to benefit from that, but not Pentium due to its slow
-plain SHL and SHR.)
