Note that for LDC, an even more optimal arrangement is something like[1]:
-
version(LDC)
import ldc.llvmasm;
creal expi(real y) {
return __asm!(creal)("fsincos", "={st(0)},={st(1)},0", y);
}
-
My appologies if I

While implementing some code I have seen that LDC (that uses Tango) isn't able
to inline the code of expi, that is little more than a fsincos asm instruction.
LDC is now able to inline sqrt, etc (that increases their efficiency a lot),
but expi contains asm, and such function
