I published an article on Cloudflare blog:

• Branch predictor: How many "if"s are too many? Including x86 and M1 benchmarks!

Notable discussions mentioning this work:

• Looking at BTB behavior and size: a comment on my work from Travis Downs, followed by response from Linus Torvalds.

• Discussion on M1 architecture, with fascinating take on branch predictor interactions with iCache prefetcher.

• Hacker News commentary
