Hi Raman,

Thank you for the contribution! It would be nice to have a more efficient implementations of standard library functions.

That said, this PR description lacks any context / background for the work, and contains a lot
of content which is not consistent with llvm-libc coding conventions, project structure, etc.

I would strongly encourage you to look at the discussion in
https://discourse.llvm.org/t/rfc-llvm-ai-tool-policy-human-in-the-loop/89159, specifically the notes on extractive contributions, tool usage transparency and starting small.

Has this been previously discussed with llvm-libc maintainers? If they would agree on replacing the existing
implementation with a more efficient one (paying the cost of possible additional complexity), can we track this
as an issue and take small steps towards upstreaming this work?
