Tracing for developers of native methods.
The existing -verbose:jni is mainly useful for VM developers hacking on the JNI
implementation; this is intended to replace the ad hoc logging developers of
native methods need to write.
Use "-Xint:portable -Xjnitrace:ClassNameSubstring" on the command line. To
trace all native methods (mainly useful for testing the tracing), use
"-Xjnitrace:"; to trace just methods in java.util.regex.Matcher, use
"-Xjnitrace:Matcher" or "-Xjnitrace:Ljava/util/regex/Matcher;" or whatever.
To trace all the methods in Matcher and Pattern, you have to use something
like "-Xjnitrace:java/util/regex/". There's no facility for tracing an
individual method or group of methods because I haven't needed such a thing.
Here's a basic example:
-> Ljava/nio/charset/Charsets;.toUtf8Bytes([CII)[B (0x400474b8, 0, 5)
<- Ljava/nio/charset/Charsets;.toUtf8Bytes([CII)[B returned 0x40047548
Here's an example of a non-static native method:
-> Lorg/apache/harmony/luni/platform/OSFileSystem;.writeImpl(I[BII)J this=0x40012e78 (1, 0x400476d0, 0, 5)
<- Lorg/apache/harmony/luni/platform/OSFileSystem;.writeImpl(I[BII)J returned 5
Here's an interesting example showing another native method being called, and
an exception being thrown by a native method:
-> Ljava/lang/VMClassLoader;.loadClass(Ljava/lang/String;Z)Ljava/lang/Class; (0x400466b8, false)
-> Ljava/lang/Throwable;.nativeFillInStackTrace()Ljava/lang/Object; ()
<- Ljava/lang/Throwable;.nativeFillInStackTrace()Ljava/lang/Object; returned 0x400467c8
<- Ljava/lang/VMClassLoader;.loadClass(Ljava/lang/String;Z)Ljava/lang/Class; threw Ljava/lang/ClassNotFoundException;
(This functionality needs to be enabled at compile time. A later patch will
address that.)

Fix for x86-atom/CALLABI.S to handle failure for android.jni.cts.JniStaticTest#test_returnChar. CALLABI.S was not returning unsigned shorts correctly.

This is a contribution of x86-atom targeted assembly for the fast byte-code interpreter engine. This is an initial contribution with minimal optimizations that target the Intel ATOM processor. We expect to continuously improve this code. It is expected that there will be a discussion on the potential merge of this code and similar efforts (i.e. the mterp/x86 directory first included with cupcake). While this code is intended to target ATOM and not a generic X-86 processor, we were able to show the following improvements over the c-portable interpreter using the simulator build:
Build: TARGET_SIMULATOR: true
TARGET_BUILD_TYPE: release
TARGET_PRODUCT: sim
Environment: Intel(R) Core(TM)2 Quad CPU Q9550 @ 2.83GHz
PI = Portable Interpreter
IA = Fast IA Interpreter
Embedded CaffeineMark: (IA-PI)/PI: Average of 70% improvement on overall score
SPECjbb2000*: (IA-PI)/PI: Average of 37% improvement on raw score
SPECjvm98*: (PI/IA) Speedup: Mtrt: 1.2; Jess: 1.34; Compress: 1.57; Db: 1.46; Jack: 1.28
* SPECjbb2000 - 1 warehouse. Noncompliant - modified to run on Dalvik
* SPECjvm98 - Noncompliant - modified to run on Dalivk
