2022-10-11Reland^2 "Update instrumentation support for non-java debuggable runtimes" Mythri Alle
This reverts commit 778800e334a3fd0f29dbeabad114032bc849a9d1. Reason for revert: Reland after fixes. Fixes: 1. Update Trace::Start and Trace::Stop to turn on JavaDebuggable, so that necessary support exists for method tracing. Earlier we used to just use interpreter in non-debuggable runtimes. Now we are adding the ability to switch the runtime to debuggable when required. Earlier CL missed updating tracing. 2. Allow installing JITed code with instrumentation support when instrumentation support is required. We disallowed any JITed code for native methods if instrumentation support is needed. 3. Allow loading app images in debuggable runtimes, since we may want to use the AOT code after turning off debuggable. 4. Mark a few tests related to cha (616-cha*) and a test related to dead references (1339-dead-reference-safe) as expected to fail in trace configuration since certain optimizations are disabled in debuggable runtimes. 5. Also temporarily mark 667-jit-jni-stub as expected failure since Jit GC is turned off with tracing. Change-Id: I853113781f1a8c367b01529b8f7337cd2604d4a3 Bug: 206029744

2022-09-07Reland "Update instrumentation support for non-java debuggable runtimes" Mythri Alle
This reverts commit 7cc22bb96e4e05cf63661eed7fd3dda5304bdacc. Reason for revert: Relanding after a fix for jit-on-first-use failures. The fix: 1. When shutting down jvmti agent, pause Jit threads and discard all JITed code. 2. Update the jit compiler options when transitioning the runtime debug state.

2021-11-29Handle baseline/optimized compilation kind in the runtime. Nicolas Geoffray
It used to be adjusted in the compiler, but that does not work anymore as the compiler now always requests a baseline compilation to have a profiling info. Test: 457-regs Bug: 146423102 Change-Id: I522bc515ef1c6f8737ada311265a6f8e0f4db3fd

2019-08-28JIT mini-debug-info: Support JIT data dual mapping. David Srbecky
Ensure that we can add/remove mini-debug-info if the JIT data is read-only and we need to use the other mapping for writes. Pointers into the read-only memory are marked as "const".

2018-11-21Refactor code around JIT creation. Nicolas Geoffray
- Create the JIT early on. - Have dedicated zygote spaces, that get assign after the fork. - Re-parse compiler options after fork to take into account customization of debug flags by the child. Currently, we only create the thread pool in the child, so the zygote isn't jitting yet. Bug: 119800099 Test: test.py, device boots Change-Id: I591ce933ebf54a67937ab1d05206534f55ef2f65

2016-10-27ART jitted code profiling support. xueliang.zhong
- 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. Change-Id: I1bd3ce280f953811d3dfcc27dc8e59b3e1f481aa
2016-09-30Simplify our intrinsic recognizer. Nicolas Geoffray
- Use the modifiers for storing the intrinsic kind. - Delete dex_file_method_inliner and its associated map. This work was also motivated by the fact that the inline method analyzer leaks intrinsic tables, and even worse, might re-use a table from one dex file to another unrelated dex file in the presence of class unloading and the unlikely event of the dex files getting the same address. test: m test-art-host m test-art-target Change-Id: Ia653d2c72df13889dc85dd8c84997582c034ea4b

2015-05-29Move mirror::ArtMethod to native Mathieu Chartier
Optimizing + quick tests are passing, devices boot. TODO: Test and fix bugs in mips64. Saves 16 bytes per most ArtMethod, 7.5MB reduction in system PSS. Some of the savings are from removal of virtual methods and direct methods object arrays. Bug: 19264997 Change-Id: I622469a0cfa0e7082a2119f3d6a9491eb61e3f3d

2015-02-23Add JIT Mathieu Chartier
Currently disabled by default unless -Xjit is passed in. The proposed JIT is a method JIT which works by utilizing interpreter instrumentation to request compilation of hot methods async during runtime. JIT options: -Xjit / -Xnojit -Xjitcodecachesize:N -Xjitthreshold:integervalue The JIT has a shared copy of a compiler driver which is accessed by worker threads to compile individual methods. Added JIT code cache and data cache, currently sized at 2 MB capacity by default. Most apps will only fill a small fraction of this cache however. Added support to the compiler for compiling interpreter quickened byte codes. Added test target ART_TEST_JIT=TRUE and --jit for run-test. TODO: Clean up code cache. Delete compiled methods after they are added to code cache. Add more optimizations related to runtime checks e.g. direct pointers for invokes. Add method recompilation. Move instrumentation to DexFile to improve performance and reduce memory usage. Bug: 17950037 Change-Id: Ifa5b2684a2d5059ec5a5210733900aafa3c51bca
