Is there any interface to call __libm_sse2_sincos under MSVC?

I'm currently working on an optimization of some C codes under MSVC, in which some sin() and cos() calculations are performed.

I use the SSE implementations like:

a = _mm_set_pd(cos(w),sin(w));

However, when I check disassembly codes later, I find that Microsoft compiler interpret cos(w) and sin(w) as follows:

call        __libm_sse2_cos 
...
call        __libm_sse2_sin 

In which cos and sin are called separately. But I would expect that compiler call __libm_sse2_sincos to calculate sin and cos with the same radian simultaneously.

So is it possible that I tell compiler to do this? or any inter开发者_运维技巧face to call them under MSVC? How about under Linux?

Thanks a lot for the help.

Why not just do this:

double s, c;

sincos(w, &s, &c);
a = _mm_set_pd(c, s);

?

if you want sincos under MSVC, you can use the implementation(s) from the XNA math library, namely XMVectorSinCos and XMScalarSinCos, which suck as they are float only or you need to use an external library like AMD's LibM (for x64 only) or a smaller time one like this.
