> This PR proposes to fix a performance regression (on x64 platforms) for > 32-bit strings introduced by > [JDK-8345120](https://bugs.openjdk.org/browse/JDK-8345120). > > The PR also fixes a performance regression in the benchmarks caused by using > the wrong type for `MemorySegment`. > > Regrettably, this PR uses different code paths for various architectures. > This gives optimum performance for all platforms at the expense of slightly > more code complexity.
