Differences between __sqrtf() vs sqrtf() functions

In relation to this post I was reading...

http://e2e.ti.com/support/development_tools/compiler/f/343/t/218750.aspx

Can someone describe the differences between using the __sqrtf() compiler intrinsic function vs the sqrtf() function provided by the rtsv7R4_T_be_v3D16_eabi.lib library?  There seems to be significantly more overhead to the sqrtf() function vs the intrinsic function.  Is there a good reason to use the library function instead of the intrinsic function?

I'm currently using the 4.9.5 compiler on the TMS570 product line.
