Why does changing 0.1f to 0 slow down performance by 10x?
...
@s73v3r That's a very good question. Now that I look at the assembly, not even + 0.0f gets optimized out. If I had to guess, it could be that + 0.0f would have side-effects if y[i] happened to be a signalling NaN or something... I could be wrong though.

Why do x86-64 instructions on 32-bit registers zero the upper part of the full 64-bit register?
...endency madness is one of the reasons that 16-bit instructions are avoided now. x86-64 inherited this from 8086 for 8-bit and 386 for 16-bit, and decided to have 8 and 16-bit registers work the same way in 64-bit mode as they do in 32-bit mode.
