You seem to have a quite recent CPU, as the G++ code contains
instructions like vmovsd. So you can try to do the same with
ldc2, and use AVX or AVX2.
There are the switches:
-march=<string> - Architecture to generate code for:
-mattr=<a1,+a2,-a3,...> - Target specific attributes
(-mattr=help for details)
-mcpu=<cpu-name> - Target a specific cpu type
(-mcpu=help for details)
LDC basically generated something that I can only call "one
straight *whoooosh*"...
