  Log Message:
  -----------
  [libc] New version of the mem* framework

    This version is more composable and also simpler at the expense of being more explicit and more verbose. It also provides minimal implementations for ARM platforms.

    Codegen can be checked here https://godbolt.org/z/chf1Y6eGM
