compiling xmmintrin.h

[ranjith kumar]

Hi,
    I wrote a c program which uses functions and data
types defined in xmmintrin.h.
 Suprisingly,  in assembly code, produced by gcc, each
function call is replaced by a single assembly
instruction.

What is the special about functions defined in
xmmintrin.h.
How they are compiled by gcc?

Any answers or any matirial?
Thanks in advance.
