Hi,
The intrinsic_doc.txt is attached. It is the piece of iWMMXt intrinsic details doc picked out from "Intel Wireless MMX Technology Intrinsic Support" with some modification.

I couldn't find any material to show why __int64 needs to be redefined. And all the tests are passed without this change. So decide to discard this change.

See the intrinsics doc. It says the description of _mm_cvtsi32_si64 is "The integer value is zero-extended to 64 bits.
If r = _mm_cvtsi32_si64(i), then the action is
r [0:31] = i;
r[32:63] = 0;"

The description of _mm_andnot_si64 is "Performs a logical NOT on the 64-bit value in m1 and use the result in a bitwise AND with the 64-bit value in m2."
And, "wandn wRd, wRn, wRm" means "wRd = wRn & ~wRm"
I think __builtin_arm_wandn had better directly match the behavior of wandn.
Therefore, match _mm_andnot_si64 (m1, m2) to __builtin_arm_wandn (m2, m1).
