* art: Refactor RuntimeOptions/ParsedOptionsIgor Murashkin2015-02-041-75/+22
| | | | | | | | | | | | | Refactor the RuntimeOptions to be a type-safe map (VariantMap, see runtime_options.h) and the ParsedOptions to delegate the parsing to CmdlineParser (see cmdline/cmdline_parser.h). This is the start of a command line parsing refactor, and may include more in the future (dex2oat, patchoat, etc). For more details of the command line parsing generator usage see cmdline/README.md Change-Id: Ic67c6bca5e1f33bf2ec60e2e3ff8c366bab91563
* Remove back-door bootclasspath option from RuntimeRichard Uhler2015-01-081-1/+1
| | | | | | | | | | | | | | | | | The 'bootclasspath' option allowed users of the Runtime to load their own boot class path DexFiles and pass them directly to the Runtime as an option. This obscures the fact that the Runtime must take ownership of the boot class path DexFiles. This change removes the use of the bootclasspath option by dex2oat and the common runtime tests. For dex2oat, we use the existing -Xbootclasspath option instead, and introduce a new -Xbootclasspath-locations option to override the dex locations for the loaded boot class path dex files. For the common runtime tests, we simply use -Xbootclasspath. Bug: 18809837 Change-Id: Idfcd4885390bf0f3dc350993756dd337220def73
* Instruction set features for ARM64, MIPS and X86.Ian Rogers2014-11-131-1/+1
| | | | | | | | | | | | | Also, refactor how feature strings are handled so they are additive or subtractive. Make MIPS have features for FPU 32-bit and MIPS v2. Use in the quick compiler rather than #ifdefs that wouldn't have worked in cross-compilation. Add SIMD features for x86/x86-64 proposed in: https://android-review.googlesource.com/#/c/112370/ Bug: 18056890 Change-Id: Ic88ff84a714926bd277beb74a430c5c7d5ed7666
* Add runtime options for large object spaceMathieu Chartier2014-09-161-0/+3
| | | | | | | | | | | | | | | Adds the two following options: Option -XX:LargeObjectSpace={freelist, map, disabled} Option -XX:LargeObjectThreshold=size specifies the size for which primitive arrays are allocated in the large object space. Added handling for large object space == null in collectors. Fixed an error in the mem map space where we didn't use the page aligned size LOS for bytes allocated, this resutled in heaps appearing a bit smaller than they should be.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | When the non moving space becomes full, we disable moving GC and make the main space the new non moving space. Also added a runtime option for changing the non moving space size: -XX:NonMovingSpaceCapacity.

This will initialize the native bridge library but mark it as unavailable. - also, rename native_bridge_library_path to native_bridge_library_filename to be closer to the actual meaning (it's just the filename without any path).

* ART: Compacting ROS/DlMalloc spaces with semispace copy GCZuo Wang2014-07-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current semispace copy GC is mainly associated with bump pointer spaces. Though it squeezes fragmentation most aggressively, an extra copy is required to re-establish the data in the ROS/DlMalloc space to allow CMS GCs to happen afterwards. As semispace copy GC is still stop-the-world, this not only introduces unnecessary overheads but also longer response time. Response time indicates the time duration between the start of transition request and the start of transition animation, which may impact the user experience. Using semispace copy GC to compact the data in a ROS space to another ROS(or DlMalloc space to another DlMalloc) space solves this problem. Although it squeezes less fragmentation, CMS GCs can run immediately after the compaction. We apply this algorithm in two cases: 1) Right before throwing an OOM if -XX:EnableHSpaceCompactForOOM is passed in as true. 2) When app is switched to background if the -XX:BackgroundGC option has value HSpaceCompact. For case 1), OOMs are significantly delayed in the harmony GC stress test, with compaction ratio up to 0.87. For case 2), compaction ratio around 0.5 is observed in both built-in SMS and browser. Similar results have been obtained on other apps as well.

* Enable concurrent sweeping for non-concurrent GC.Mathieu Chartier2014-04-291-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactored the GarbageCollector to let all of the phases be run by the collector's RunPhases virtual method. This lets the GC decide which phases should be concurrent and reduces how much baked in GC logic resides in GarbageCollector. Enabled concurrent sweeping in the semi space and non concurrent mark sweep GCs. Changed the semi-space collector to have a swap semi spaces boolean which can be changed with a setter. Fixed tests to pass with GSS collector, there was an error related to the large object space limit. Before (EvaluateAndApplyChanges): GSS paused GC time 7.81s/7.81s, score: 3920 After (EvaluateAndApplyChanges): GSS paused GC time 6.94s/7.71s, score: 3900 Benchmark score doesn't go up since the GC happens in the allocating thread. There is a slight reduction in pause times experienced by other threads (0.8s total). Added options for pre sweeping GC heap verification and pre sweeping rosalloc verification.

* Implicit null/suspend checks (oat version bump)Dave Allison2014-03-131-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the ability to use SEGV signals to throw NullPointerException exceptions from Java code rather than having the compiler generate explicit comparisons and branches. It does this by using sigaction to trap SIGSEGV and when triggered makes sure it's in compiled code and if so, sets the return address to the entry point to throw the exception. It also uses this signal mechanism to determine whether to check for thread suspension. Instead of the compiler generating calls to a function to check for threads being suspended, the compiler will now load indirect via an address in the TLS area. To trigger a suspend, the contents of this address are changed from something valid to 0. A SIGSEGV will occur and the handler will check for a valid instruction pattern before invoking the thread suspension check code. If a user program taps SIGSEGV it will prevent our signal handler working. This will cause a failure in the runtime. There are two signal handlers at present. You can control them individually using the flags -implicit-checks: on the runtime command line. This takes a string parameter, a comma separated set of strings. Each can be one of: none switch off null null pointer checks suspend suspend checks all all checks So to switch only suspend checks on, pass: -implicit-checks:suspend There is also -explicit-checks to provide the reverse once we change the default. For dalvikvm, pass --runtime-arg -implicit-checks:foo,bar The default is -implicit-checks:none There is also a property 'dalvik.vm.implicit_checks' whose value is the same string as the command option. The default is 'none'. For example to switch on null checks using the option: setprop dalvik.vm.implicit_checks null It only works for ARM right now. Bumps OAT version number due to change to Thread offsets. Bug: 13121132 Change-Id: If743849138162f3c7c44a523247e413785677370
