calcPi_intrinsic rework
This is a rework of calcPi_intrinsic
in v6
of the Pi calculation examples.
This should now work in macOS, but I can't test that.
I replaced built-in functions with proper Intel intrinsics and reworked the __m128d
variables.
On my machine calcPi_intrinsic
is now faster than calcPi_SSE
.
@stvogel, what do you think?
