Scumbria,

I don't know either, however they (MSFT) have begun the slow process of incorporating the new instructions into the compiler. The largest benefit of SSE2 is in using SSE2.

re: Perhaps their support is limited to inline

Not according to the documents provided, they use the word intrinsics:

Intrinsic Syntax
The following is the syntax for each intrinsic:

data_type intrinsic_name (parameters)
where data_type is the return data type (which can be void, int, __m64, __m128, __m128d, or __m128i, and only the _mm_empty intrinsic returns void) and intrinsic_name is the name of the intrinsic (which behaves like a function that you can use in your C/C++ code instead of inlining the actual instruction).

A table in each section provides the intrinsic names and the corresponding instruction. A detailed description of the intrinsic with the intrinsic's prototype and its corresponding instruction follow each table.
