* Move image intern table into imageMathieu Chartier2015-06-111-3/+6
| | | | | | | | | | | | | Previously we recreated this intern table during runtime startup. This added 50-100ms of boot time. Fixed bug where we didn't copy over hashcodes into the image. Deleted some stale code. Bug: 20727525 Bug: 19569780 Change-Id: I08959e9aa2a73cedb52f393033e2ffea3a26e76b
* Move mirror::ArtMethod to nativeMathieu Chartier2015-06-021-4/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 (cherry picked from commit e401d146407d61eeb99f8d6176b2ac13c4df1e33) Change-Id: I622469a0cfa0e7082a2119f3d6a9491eb61e3f3d Fix some ArtMethod related bugs Added root visiting for runtime methods, not currently required since the GcRoots in these methods are null. Added missing GetInterfaceMethodIfProxy in GetMethodLine, fixes --trace run-tests 005, 044. Fixed optimizing compiler bug where we used a normal stack location instead of double on ARM64, this fixes the debuggable tests. TODO: Fix JDWP tests. Bug: 19264997 Change-Id: I7c55f69c61d1b45351fd0dc7185ffe5efad82bd3 ART: Fix casts for 64-bit pointers on 32-bit compiler. Bug: 19264997 Change-Id: Ief45cdd4bae5a43fc8bfdfa7cf744e2c57529457 Fix JDWP tests after ArtMethod change Fixes Throwable::GetStackDepth for exception event detection after internal stack trace representation change. Adds missing ArtMethod::GetInterfaceMethodIfProxy call in case of proxy method. Bug: 19264997 Change-Id: I363e293796848c3ec491c963813f62d868da44d2 Fix accidental IMT and root marking regression Was always using the conflict trampoline. Also included fix for regression in GC time caused by extra roots. Most of the regression was IMT. Fixed bug in DumpGcPerformanceInfo where we would get SIGABRT due to detached thread. EvaluateAndApplyChanges: From ~2500 -> ~1980 GC time: 8.2s -> 7.2s due to 1s less of MarkConcurrentRoots Bug: 19264997 Change-Id: I4333e80a8268c2ed1284f87f25b9f113d4f2c7e0 Fix bogus image test assert Previously we were comparing the size of the non moving space to size of the image file. Now we properly compare the size of the image space against the size of the image file. Bug: 19264997 Change-Id: I7359f1f73ae3df60c5147245935a24431c04808a [MIPS64] Fix art_quick_invoke_stub argument offsets. ArtMethod reference's size got bigger, so we need to move other args and leave enough space for ArtMethod* and 'this' pointer. This fixes mips64 boot.

* ART: Clean up arm64 kNumberOfXRegisters usage.Vladimir Marko2015-05-261-1/+0
| | | | | | | | | | | | | | | | | | | | | Avoid undefined behavior for arm64 stemming from 1u << 32 in loops with upper bound kNumberOfXRegisters. Create iterators for enumerating bits in an integer either from high to low or from low to high and use them for <arch>Context::FillCalleeSaves() on all architectures. Refactor runtime/utils.{h,cc} by moving all bit-fiddling functions to runtime/base/bit_utils.{h,cc} (together with the new bit iterators) and all time-related functions to runtime/base/time_utils.{h,cc}. Improve test coverage and fix some corner cases for the bit-fiddling functions.

* Relocate DWARF using .oat_patches.David Srbecky2015-04-111-5/+0
| | | | | | | | | | | | | | | | | | | | | | The current solution is to hard-code knowledge of DWARF in the linker. This works for simple use of DWARF, but breaks as soon as I try to do anything more complex. Making the linker fully support DWARF would be non-trivial task and would be essentially rewrite. Using .oat_patches is much easier solution. Relocating .debug_* sections required extending .oat_patches to support more sections than just .text. I have encoded each section as null-terminated section name followed by ULEB128 deltas. The ULEB128 encoding shrinks .oat_patches for .text by factor of about 6 with 64-bit compiler, and factor of 3 with 32-bit compiler. On the other hand, it grows by the extra .oat_patches for DWARF which were not present before (if debug symbols are included). Overall, it is still a clear improvement even with the DWARF patches.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add linear alloc. Moved ArtField to be native object.

* Change 64 bit ArtMethod fields to be pointer sizedMathieu Chartier2014-11-181-8/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | Changed the 64 bit entrypoint and gc map fields in ArtMethod to be pointer sized. This saves a large amount of memory on 32 bit systems. Reduces ArtMethod size by 16 bytes on 32 bit. Total number of ArtMethod on low memory mako: 169957 Image size: 49203 methods -> 787248 image size reduction. Zygote space size: 1070 methods -> 17120 size reduction. App methods: ~120k -> 2 MB savings. Savings per app on low memory mako: 125K+ per app (less active apps -> more image methods per app). Savings depend on how often the shared methods are on dirty pages vs shared. TODO in another CL, delete gc map field from ArtMethod since we should be able to get it from the Oat method header. Bug: 17643507 Change-Id: Ie9508f05907a9f693882d4d32a564460bf273ee8 (cherry picked from commit e832e64a7e82d7f72aedbd7d798fb929d458ee8f)
* Instruction set features for ARM64, MIPS and X86.Ian Rogers2014-11-131-2/+2
| | | | | | | | | | | | | 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
* ART: Add support for patching and loading OAT files compiled with PICIgor Murashkin2014-10-271-3/+38
| | | | | | | | | | | | * Images (.art) compiled with pic now have a new field added. * isDexOptNeeded will now skip patch-ing for apps compiled PIC * First-boot patching now only copies boot.art, boot.oat is linked As a result, all system preopted dex files (with --compile-pic) no longer take up any space in /data/dalvik-cache/<isa>.

* ART: Fix some -Wpedantic errorsAndreas Gampe2014-09-291-1/+1
| | | | | | | | | | | | | | | | Remove extra semicolons. Dollar signs in C++ identifiers are an extension. Named variadic macros are an extension. Binary literals are a C++14 feature. Enum re-declarations are not allowed. Overflow. Change-Id: I7d16b2217b2ef2959ca69de84eaecc754517714a
* Make patchoat use the sht_entsize when patching.Alex Light2014-08-061-2/+3
| | | | | | This fixes an occasional problem with multiarch use of patchoat. Change-Id: I80799de36774720bd985704f9b709a8378bb5af5
* Runtime can now be set to require relocationAlex Light2014-07-221-0/+1
| | | | | | | | | | | | | | 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.

* Add patchoat tool to Art.Alex Light2014-07-071-0/+119
Add a new executable called patchoat to art. This tool takes already compiled images and oat files and changes their base address, acting as a cheap form of relocation. Add a --include-patch-information flag to dex2oat and code to add required patch information to oat files created with the quick compiler.
