It made little difference: LDC compiled into AVX2 vectorized addition

Measurements without -mcpu=native:
overhead 0.336s
bytes    0.610s
without branch hints 0.852s
code pasted 0.766s

So we should be able to reduce overhead by means of proper code arrangement and interplay of inlining and outlining. The prize, however, would be to get the AVX instructions for ASCII going. Is that possible? -- Andrei
