[aarch64-port-dev ] 回复：RFR: 8149733: AArch64: refactorchar_array_equals/byte_array_equals/string_equals

[Andrew Haley]

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.
