I was trying to find where the trigonometric functions BODIES are and couldn't found anything.
In the file builtin.c  there are many references to the functions, but not the bodies.
Could you help me, please. Thank you very much.

  I don't know if gcc has builtin versions of them, but I did found some [assembler] bodies in
GLIBC (eg: sysdeps/x86_64/fpu/s_cosl.S). Could these be them?

They seem to me to be there.  Look at expand_builtin_pow(), for
example.  

But only the mathematical functions that are gcc builtins are handled
in builtins.c: other functions that are library calls are part of
libc, the GNU version of which is at http://www.gnu.org/software/libc/

Andrew.
