Replace the custom unsigned divide / remainder functions with the compiler-optimized Long.divideUnsigned / remainderUnsigned.
No new tests. Existing tier1-3 tests continue to pass. I added a new set of divide benchmarks. Results in thread. I also removed the BigDecimal.toString benchmarks. They no longer serve their purpose - toString caches the returned value, so we were only benchmarking the cache access time. ------------- Commit messages: - Fix whitespace - Remove useless toString benchmarks - Update copyright - Remove redundant benchmarks - Use unsigned ops in BigDecimal - Simplify logic - Use divide/remainderUnsigned - Add BigInteger.divide microbenchmark Changes: https://git.openjdk.org/jdk/pull/19134/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=19134&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8331907 Stats: 212 lines in 4 files changed: 39 ins; 132 del; 41 mod Patch: https://git.openjdk.org/jdk/pull/19134.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/19134/head:pull/19134 PR: https://git.openjdk.org/jdk/pull/19134
