* Load boot image at a random address.Vladimir Marko2018-09-261-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | And perform in-place fixup of references and pointers. This dirties all the boot image memory loaded by zygote, so there shall be no "shared clean" boot image pages anymore, these shall change to "shared dirty". However, as we're using a profile-based boot image, these pages are presumably used often enough and unlikely to be paged out anyway. The in-place fixup takes around 60-120ms when starting the zygote on aosp_taimen-userdebug. However, an experiment with MAP_POPULATE pushes the raw fixup down to around 12-15ms. If we used compressed images, this would be the actual time for fixup as the data would be already present in memory. If we keep using uncompressed images, we shall need to tune the loading with MAP_POPULATE or MADV_WILLNEED. The -Xrelocate/-Xno-relocate option is re-interpreted from "use patchoat if needed" to "relocate the boot image in memory if possible". We do not allow relocation for the AOT compilation to speed up dex2oat execution and help producing deterministic output. The patchoat tool shall be removed in a follow-up CL.

* Move some remaining dex utilitiesDavid Sehr2018-03-191-1/+1
| | | | | | | | | There were several utilities related to building/walking/testing dex files that were not in libdexfile. This change consolidates these. Bug: 22322814 Test: make -j 50 test-art-host Change-Id: Id76e9179d03b8ec7d67f7e0f267121f54f0ec2e0
* ART: Allow oatstatus verification for app dependenciesAndreas Gampe2018-01-191-0/+11
| | | | | | | | | | | | | | Allow taking verification state from the oat file durin compilation if the class is a dependency (thus not being compiled itself). This is necessary in case the dependency itself has been quickened and stripped, as quickened bytecodes are not supported during compile- time verification. Expose this through the CompilerCallbacks.

* Change ClassStatus to fit into 4 bits.Vladimir Marko2018-01-051-1/+1
| | | | | | | | | | | | | | | | | In preparation for extending the type check bit string from 24 to 28 bits, rewrite ClassStatus to fit into 4 bits. Also perform a proper cleanup of the ClassStatus, i.e. change it to an enum class, remove the "Status" word from enumerator names, replace "Max" with "Last" in line with other enumerations and remove aliases from mirror::Class.

* Add support for registering classpath classes status.Nicolas Geoffray2017-09-151-0/+3
| | | | | | | | | | | | | | | | | By doing class unloading after each dex file compilation, we are loosing away verification done on classpath classes. This change introduces a new table for keeping around class status of classpath classes. Multidex quickening compilation improved by ~5% by not re-verifying classpath classes.

* Revert "Support class unloading in dex2oat for quicken multidex"Richard Uhler2017-08-091-9/+0
| | | | | | | | This reverts commit 0b1c341d2d89a483142cd14bdeb4650ab00184f1. New test Dex2oatDeterminism.UnloadCompile fails on bots gtest-debug-gc and friends. Change-Id: Ib101fc4390d90f88fe017d8482775d5e975f2ccb
* Support class unloading in dex2oat for quicken multidexMathieu Chartier2017-08-081-0/+9
| | | | | | | | | | | | | | | | | Support class unloading for the quicken compilation filter. This will be enabled in a follow up CL. Added a test that compares with and without unloading. The way that it tests this is by adding an output app image. Having an app image disables the unloading. This test also covers that app images don't change the odex (currently). Added a test for the assumed verified logic. Bug: 63467744 Test: test-art-host Test: test/testrunner/testrunner.py --interpreter --host -j40 Change-Id: I1e8a862c6f089c06c58aa0c846797e4c24bd072c
* Integrate VerifierDeps in compiler driver.Nicolas Geoffray2016-11-031-0/+1
| | | | | | | | | If a VerifierDeps is given, try fast verify. Otherwise create a new VerifierDeps and do the full verification. test: test-art-host, verifier_deps_test bug: 30937355 Change-Id: Ifb030d7b5232c95872164f601057a56ab96038e1
* Collect verifier dependenciesDavid Brazdil2016-09-161-0/+3
| | | | | | | | | | | | | | | | MethodVerifier tests whether a DEX method is valid w.r.t. the classes in class path. Since the APK does not change across OTA updates, it is not necessary to analyze the bytecode again with MethodVerifier, as long as its dependencies on the class path (which may have changed) are satisfied. This patch introduces VerifierDeps, a class path dependency collector, and adds hooks into MethodVerifier where classes/methods/fields are resolved and where assignability of types is tested.

* ART: Refactor verifier callbacksAndreas Gampe2015-12-091-2/+2
| | | | | | | | | | | | | | | | | | Change the return type of MethodVerified to void. It was never used anyways. Remove the callbacks calls from the core of the verifier (Verify()). Instead, make the convenience functions do the work, and add a parameter to supply the callback so that the verifier becomes independent of the Runtime-stored one. Fix up calls that now need to provide a callback, but leave places that only run the verifier to get metadata (e.g., register type data, lock state) without callback. This avoids callback calls when in JIT mode. Bug: 26075442 Change-Id: I2c270f01e4de088771d4d4b19dae4f07d77640f0
* Move to newer clang annotationsMathieu Chartier2015-07-221-1/+1
| | | | | | | | | | | | | | | Also enable -Wthread-safety-negative. Changes: Switch to capabilities and negative capabilities. Future work: Use capabilities to implement uninterruptible annotations to work with AssertNoThreadSuspension. Bug: 20072211 Change-Id: I42fcbe0300d98a831c89d1eff3ecd5a7e99ebf33
* ART: Some runtime cleanupAndreas Gampe2015-03-271-16/+21
| | | | | | | | Use an enum for the compiler-callback mode. Refactor and remove some unnecessary includes in runtime.h. Change-Id: If2245fa470171311b8e05b677cf6bb28f209585a
* ART: PathClassLoader for compilerAndreas Gampe2015-03-271-1/+9
| | | | | | | | | | | | | | | | | | | | Use an actual PathClassLoader when compiling apps, instead of a side structure and cutout. This CL sets up a minimal object 'cluster' that recreates the Java side of a regular ClassLoader such that the Class-Linker will recognize it and use the internal native fast-path. This CL removes the now unnecessary compile-time-classpath and replaces it with a single 'compiling-the-boot-image' flag in the compiler callbacks. Note: This functionality is *only* intended for the compiler, as the objects have not been completely initialized. Bug: 19781184 Change-Id: I7f36af12dd7852d21281110a25c119e8c0669c1d
* Runtime can now be set to require relocationAlex Light2014-07-221-0/+4
| | | | | | | | | | | | | | Add a pair of runtime flags -Xrelocate and -Xnorelocate that can force the runtime to require that all files that are run are relocated, to prevent attacks based on the known art base address. Add support for running patchoat on oat files compiled without an image. Change run-test to have new --prebuild and --relocate flags. Bug: 15358152 Change-Id: I91166c62dd1ab80e5cbcb7883a2cd0d56afca32d
* Enable annotalysis on clang ART builds.Ian Rogers2014-03-061-1/+1
| | | | | | | | | | | Fix clang build errors aswell as restructure locking/mutex code for correct thread safety analysis support. Reorder make dependencies so that host builds build first as they should provide better compilation errors than target. Remove host's use of -fno-omit-frame-pointer as it has no value with correct use of CFI, which we should have. Change-Id: I72cea8da9a3757b1a0b3acb4081feccb7c6cef90
* Include what is usedKenny Root2014-03-041-0/+1
| | | | | If you use it, you should put an #include in it. Change-Id: I8919fe2e48adb7cc19173cc44838547a2015288f
* Move compiler code out of method verifier.Vladimir Marko2013-12-171-0/+44
We want to detect small methods for inlining at the end of the method verification. Instead of adding more compiler code to the runtime, we create a callback from the runtime into the compiler, so that we can keep the code there. Additionally, we move the compiler-related code that was already in the method verifier to the compiler since it doesn't really belong to the runtime in the first place.
