ART jitted code profiling support.
- Generate perf map for method level profiling.
- Generate jit dump for instruction level profiling.
Command line example of perf map approach:
$ perf record dalvikvm -Xcompiler-option -g -cp <classpath> MyClass
$ perf report
Command line example of perf jit dump approach:
$ perf record -k mono dalvikvm -Xcompiler-option -g -cp <classpath> MyClass
$ perf inject -i perf.data -o perf.data.jitted
$ perf report -i perf.data.jitted
$ perf annotate -i perf.data.jitted
NOTE: 4.1 or newer kernel is needed for this jit dump analysis.
Test: Compile.
Test: Verified that perf-PID.map and jit-PID.dump files are only generated
when running ART JIT with -g option. Tested on aosp_angler-userdebug
and hikey-userdebug devices. The file formats are correct.
