Re: [aarch64-port-dev ] 回复：RFR: 8149733: AArch64: refactorchar_array_equals/byte_array_equals/string_equals
by Andrew Haley 27 Feb '16

27 Feb '16

My version is at http://cr.openjdk.java.net/~aph/8149733/ The changes I made are: I rewrote most of the comments because I couldn't understand them. I intend no criticism, and I understand that English isn't the language of your birth. Please tell me if you can understand my comments. "generic_array_equals" -> "arrays_equals" Reason: it's not generic, it's only bytes and chars. Also, this is what x86_64 calls the same routine. "ary1" -> "a" Reason: "ary" just looks odd. Also, these are the names in the java code. "cmp; br.nz" -> "eor, bnz" Reason: Don't clobber flags for no reason. There's no need to check for the same arrays if we're comparing strings. Otherwise, the code is the same. I haven't much tested this, but it should give the same performance. Please test it, and tell me if I've broken anything. Thanks, Andrew.

[PATCH] [jdk8u] jvm.cfg parsing broken, resulting in broken JDK
by Andrew Hughes 25 Feb '16

25 Feb '16

Webrev: http://cr.openjdk.java.net/~andrew/aarch64-8/sync/jdk.webrev.02/ This change: http://hg.openjdk.java.net/aarch64-port/jdk8u/jdk/rev/2940c1ead99bd7635 introduced a change to jvm.cfg parsing local to the 8u port. Then, this change: http://hg.openjdk.java.net/aarch64-port/jdk8u/jdk/rev/9399aa7ef558 removed part of that patch, breaking jvm.cfg parsing: "Error: missing `client' JVM at `/builddir/build/BUILD/java-1.8.0-openjdk-1.8.0.72-6.b15.fc24.aarch64/openjdk/build/jdk8.build/images/j2sdk-image/jre/lib/aarch64/client/libjvm.so'." [0] This webrev removes the rest of 2940c1ead99bd7635 and replaces jvm.cfg with the version used in OpenJDK 9, allowing aarch64/jdk8u to build again. Ok to push?
