- Reviewed by Benjamin Poulain.
-
- Add a microbenchmark for a case of StringReplace that we hadn't covered with a microbenchmark
- yet: using something absurd for the replace value. This is interesting for implementing the
- 32_64 version of StringReplace, which gets really weird in the absurd case because of how it
- consumes the entire register file while making the call on x86-32.
