* ART: Clean up compilerAndreas Gampe2014-08-224-37/+234
| | | | | | | Clean up the compiler: less extern functions, dis-entangle compilers, hide some compiler specifics, lower global includes. Change-Id: Ibaf88d02505d86994d7845cf0075be5041cc8438
* Replace memory barriers to better reflect Java needs.Hans Boehm2014-07-111-7/+7
| | | | | | | | | | | | | | | | Replaces barriers that enforce ordering of one access type (e.g. Load) with respect to another (e.g. store) with more general ones that better reflect both Java requirements and actual hardware barrier/fence instructions. The old code was inconsistent and unclear about which barriers implied which others. Sometimes multiple barriers were generated and then eliminated; sometimes it was assumed that certain barriers implied others. The new barriers closely parallel those in C++11, though, for now, we use something closer to the old naming. Bug: 14685856 Change-Id: Ie1c80afe3470057fc6f2b693a9831dfe83add831
* Make class status volatile.Ian Rogers2014-06-021-0/+4
| | | | | | | Discourage loads and stores from reordering around the status being updated. Bug: 15347354 Change-Id: Ice805cb834617747c8209e98a142d3e5c7585719
* Now we have a proper C++ library, use std::unique_ptr.Ian Rogers2014-05-195-22/+21
| | | | | | | Also remove the Android.libcxx.mk and other bits of stlport compatibility mechanics. Change-Id: Icdf7188ba3c79cdf5617672c1cfd0a68ae596a61
* Give Compiler a back reference to the driver.Ian Rogers2014-05-061-12/+12
| | | | | | | | | | The compiler driver is a single object delegating work to the compiler, rather than passing it through to every Compiler call make it a member of Compiler so that it maybe queried. This simplifies the Compiler API and makes the relationship to CompilerDriver more explicit. Remove reference arguments that contravene code style.

* Use instruction specific dalvik cache dirs.Narayan Kamath2014-05-011-1/+1
| | | | | | | | | | | | - All oat & art files are now placed under /data/dalvik-cache/<isa>/. - GetDalvikCacheOrDie now requires a mandatory subdirectory argument, and is implicitly rooted under /data/. - Added helper methods to convert InstructionSet enums into strings and vice versa. (cherry picked from commit 2974bc3d8a5d161d449dd66826d668d87bdc3cbe) Change-Id: Ic7986938e6a7091a2af675ebafec768f7b5fb8cd
* Centralize instruction-set pointer-size, alignment, 64b-width codeAndreas Gampe2014-04-141-17/+2
| | | | | | | | | in instruction_set.h/cc This allows to clean up some places that currently make explicit comparisons. Change-Id: I0dcc924c52fa53306f706aceea93a2d4a655c5df
* Add command line support for enabling the optimizing compiler.Nicolas Geoffray2014-03-131-2/+2

* Object model changes to support 64bit.Ian Rogers2014-02-064-7/+7
| | | | | | | | | | | | | | | | | | | | | | | Modify mirror objects so that references between them use an ObjectReference value type rather than an Object* so that functionality to compress larger references can be captured in the ObjectRefererence implementation. ObjectReferences are 32bit and all other aspects of object layout remain as they are currently. Expand fields in objects holding pointers so they can hold 64bit pointers. Its expected the size of these will come down by improving where we hold compiler meta-data. Stub out x86_64 architecture specific runtime implementation. Modify OutputStream so that reads and writes are of unsigned quantities. Make the use of portable or quick code more explicit. Templatize AtomicInteger to support more than just int32_t as a type. Add missing, and fix issues relating to, missing annotalysis information on the mutator lock. Refactor and share implementations for array copy between System and uses elsewhere in the runtime. Fix numerous 64bit build issues. Change-Id: I1a5694c251a42c9eff71084dfdd4b51fff716822
* Add VerfiedMethod to DexCompilationUnit.Vladimir Marko2014-01-281-6/+5
| | | | | | Avoid some mutex locking and map lookups. Change-Id: I8e0486af77e38dcd065569572a6b985eb57f4f63
* Refactor verification results.Vladimir Marko2014-01-281-2/+2
| | | | | | | | Rename VerificationMethodsData to VerificationResults. Create new class VerifiedMethod to hold all the data for a given method. Change-Id: Ife1ac67cede20f3a2f9c7f5345f08a851cf1ed20
* Remove intialized static storage from dex cache.Ian Rogers2014-01-082-46/+22
| | | | | | | | | The initialized static storage array is used by compiled code to determine if for a sget/sput class initialization is necessary. The compiled code typically doesn't require this test as the class is pre-initialized or the class being accessed is the same as the current method. Change-Id: Icbc45e692b3d0ac61e559e69edb6c9b29439e571
* Move compiler code out of method verifier.Vladimir Marko2013-12-171-1/+3
| | | | | | | | | | | | 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.

* Inflate contended lock word by suspending owner.Ian Rogers2013-10-027-232/+3
| | | | | | | | | | | | | | | | | | | | Bug 6961405. Don't inflate monitors for Notify and NotifyAll. Tidy lock word, handle recursive lock case alongside unlocked case and move assembly out of line (except for ARM quick). Also handle null in out-of-line assembly as the test is quick and the enter/exit code is already a safepoint. To gain ownership of a monitor on behalf of another thread, monitor contenders must not hold the monitor_lock_, so they wait on a condition variable. Reduce size of per mutex contention log. Be consistent in calling thin lock thread ids just thread ids. Fix potential thread death races caused by the use of FindThreadByThreadId, make it invariant that returned threads are either self or suspended now. Code size reduction on ARM boot.oat 0.2%. Old nexus 7 speedup 0.25%, new nexus 7 speedup 1.4%, nexus 10 speedup 2.24%, nexus 4 speedup 2.09% on DeltaBlue. Change-Id: Id52558b914f160d9c8578fdd7fc8199a9598576a
* Use class def index from java.lang.Class.Ian Rogers2013-09-191-2/+2
| | | | | | | | | | | | Bug: 10244719 Depends on: https://googleplex-android-review.git.corp.google.com/362363 This removes the computation of the dex file index, when necessary this is computed by searching the dex file. Its only necessary in dalvik.system.DexFile.defineClassNative and DexFile::FindInClassPath, the latter not showing up significantly in profiling with this change.

* | Shard dedupe set locks.Ian Rogers2013-09-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | We're seeing contention during compilation on the dedupe locks, sharding 4 ways on an occam brings down contention by > 5x. Improve dedupe hash function to have a FNV hash function at its heart. Improve naming of dedupe locks. Tidy portable JNI compiler paramters to be pointers, given that's their primary use.

This enables deduplication to be performed on multiple threads. Also added a hash function to avoid excessive comparison of byte arrays.
