kandi X-RAY | nanobench Summary

nanobench is a C++ library typically used in Testing, Performance Testing applications. nanobench has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

ankerl::nanobench is a platform independent microbenchmarking library for C++11/14/17/20. The whole executable runs for ~60ms and prints. Which github renders as. The benchmarked code takes 7.52 nanoseconds to run, so ~133 million times per seconds. Measurements fluctuate by 1.1%. On average 6.65 instructions are executed in 24.07 CPU cycles, resulting in 0.276 instructions per second. A single branch is in the code, which branch prediction missed in 8.9% of the cases. Total runtime of the benchmark with the name some double ops is 0.00, so just a few milliseconds.

Asked 2022-Jan-23 at 16:19

I am using a C library which uses various fixed-sized unsigned char arrays with no null terminator as strings.

I've been converting them to std::string using the following function:

QUESTION

Why is POP slow when using register R12?

Asked 2020-Nov-12 at 01:52

On recent Intel CPUs, the POP instruction usually has a throughput of 2 instructions per cycle. However, when using register R12 (or RSP, which has the same encoding except for the prefix), the throughput drops to 1 per cycle if the instructions go through the legacy decoders (the throughput stays at around 2 per cycle if the µops come from the DSB).

This can be reproduced using nanoBench as follows:

Workaround: the pop r/m64 encoding of pop r12 doesn't have this decode penalty. (Thanks @Andreas for testing my guess.)
