Hi Toon,

Thanks for the review. My origin intent is to introduce MoveDouble, MoveDouble and MoveInteger64 (they all need 64-bit move instruction, an alternative is to use MoveQuadWord, see https://codereview.chromium.org/26216008/), after that, introduce a new Move macro instruction for all the other movq usage. For x64,
this new Move is implemented by movq and for X32, it is implemented by movl.

I am not sure movp is a right abstraction for all the other movq usages. For the
difference between x64 and x32:
1) Nearly all the movq in the x64 port needs to be replaced with movl by the
script.
    2) 64-bit movq needs to be kept, they are doubles, integer64 and return
address. I have used __k annotation in the X64 code so the script does not
translate them into movl.

Thanks

Would it be possible to use movp rather than MoveReturnAddress, and keep movq rather than introducing MoveInteger64? Movp would just mov a platform-specific
pointer-sized value, while movq and movl would do what the name indicates.

If there's no other reason you introduced those specific Move* functions, I'd
prefer to not overspecify the intent. Otherwise we end up with lots of
specific
macro instructions that add more noise than value.
