This patch removes the CharacterData.isOtherUppercase and isOtherLowercase methods. It also exploits the fact that isOtherUppercase is always false for all codepoints in the CharacterDataLatin1 range for a small speed-up. I have no means to test if this is correct on PPC, which has intrinsics for isLowerCase/isUpperCase, but unless I'm reading the code wrong the intrinsic for isLowerCase on PPC already appears to effectively do the fused logic of isLowerCase(ch) || isOtherLowerCase(ch) since it handles the two values where isLowerCase and isOtherLowercase disagrees (0xaa, 0xba), which means this change should make the intrinsic and the java code be in better agreement. ------------- Commit messages: - Fold CharacterData.isOtherUpper-/Lowercase into isUpper-/LowerCase Changes: https://git.openjdk.java.net/jdk/pull/2846/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=2846&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8263091 Stats: 98 lines in 8 files changed: 1 ins; 71 del; 26 mod Patch: https://git.openjdk.java.net/jdk/pull/2846.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/2846/head:pull/2846 PR: https://git.openjdk.java.net/jdk/pull/2846
