Is there ever a case where using a constant pool isn’t optimal from an execution time POV? Shouldn’t it be 1 cycle if in L1 d-cache?

L1-dcache access in 1 cycle? Which cpu/uarch? I would expect this to be around 4-5 cycles. http://agner.org has Ryzen & Skylake at latency 4.

Ah, for some reason I was under the impression that L1 was faster than it is. My mistake!
