Verified with dedicated micro benchmarks on Neoverse V1 hardware.
Instruction | uop/Latency/RThroughput
--------------------------------------------------------
ldp (X-form, offset) | 3/4/1.00
ldpsw (offset) | 3/5/0.50
ldp (X-form, pre-post) | 4/4/1.00
ldpsw (pre-post) | 4/5/0.75
ld[n]p X form has the same throughput as 3 ldr X on Neoverse V1, so consider L[3] resources for these instructions: throughput 3/3. ld[n]p X form post pre index: L[3] + I[1]: throughput 3/3. ldpsw has approximatively the throughput of ld[n]p w-form (L[1]) + 2 sxtw (I[2]): throughput 4/2 ldpsw (post/pre index): add on I uop: L[1] + I[3]: throughput 4/3
