This PR contains API and implementation changes for [JEP-414 Vector API (Second Incubator)](https://openjdk.java.net/jeps/414), in preparation for when targeted.
Enhancements are made to the API for the support of operations on characters, such as for UTF-8 character decoding. Specifically, methods for loading/storing a `short` vector from/to a `char[]` array, and new vector comparison operators for unsigned comparisons with integral vectors. The x64 implementation is enhanced to supported unsigned comparisons.
Enhancements are made to the API for loading/storing a `byte` vector from/to a `boolean[]` array.
The testing of loads/stores can be expanded for scatter/gather, but before doing that i think some refactoring of the tests is required to reposition tests in the right classes. I would like to do that work after integration of the PR.
Paul Sandoz has updated the pull request incrementally with one additional commit since the last revision: JavaDoc refs for unsigned operators. ------------- Changes: - all: https://git.openjdk.java.net/jdk/pull/3803/files - new: https://git.openjdk.java.net/jdk/pull/3803/files/93b093c1..aa6bb717 Webrevs: - full: https://webrevs.openjdk.java.net/?repo=jdk&pr=3803&range=02 - incr: https://webrevs.openjdk.java.net/?repo=jdk&pr=3803&range=01-02 Stats: 16 lines in 1 file changed: 12 ins; 0 del; 4 mod Patch: https://git.openjdk.java.net/jdk/pull/3803.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/3803/head:pull/3803 PR: https://git.openjdk.java.net/jdk/pull/3803
