call _libm_sse2_sincos and _libm_sse2_log

[vtuneuser]

I found the following calls from the asm/source code listing,

call _libm_sse2_sincos

call _libm_sse2_log

My guess was the compiler is calling the math library to use sse2 instructions to performace some math functions such as sin,cosin or log? Does any one know about this and can confirm my guess was correct?

Thanks.

Yes, icc provides a library of sse2 coded math functions. sincos would return both sin() and cos() of the same argument. This should provide better performance than x87 coded functions, when called directly from sse2 code. There are also "short vector" versions in libsvml, which icc may invoke automatically.
