* Replace String CharArray with internal uint16_t array.Jeff Hao2015-04-271-1/+43
| | | | | | | | | | | | Summary of high level changes: - Adds compiler inliner support to identify string init methods - Adds compiler support (quick & optimizing) with new invoke code path that calls method off the thread pointer - Adds thread entrypoints for all string init methods - Adds map to verifier to log when receiver of string init has been copied to other registers. used by compiler and interpreter Change-Id: I797b992a8feb566f9ad73060011ab6f51eb7ce01
* Quick: Clean up temp use counting.Vladimir Marko2015-04-081-0/+5
| | | | | | | | | | | | | | | | | For the boot image on arm64 and x86-64 we're using true PC-relative addressing, so pc_rel_temp_ is nullptr and CanUsePcRelDexCacheArrayLoad() returns true, but we're not actually using the ArtMethod* so fix the AnalyzeMIR() to take it into account. Also don't count intrinsic invokes towards ArtMethod* uses. To avoid repeated method inliner inquiries about whether a method is intrinsic or special (requiring lock acquisition), cache that information in MirMethodLoweringInfo. As part of that cleanup, take quickened invokes into account for suspend check elimination. Change-Id: I5b4ec124221c0db1314c8e72675976c110ebe7ca
* Remove -Wno-unused-parameter and -Wno-sign-promo from base cflags.Ian Rogers2014-11-031-4/+4
| | | | | | | | | | | Fix associated errors about unused paramenters and implict sign conversions. For sign conversion this was largely in the area of enums, so add ostream operators for the effected enums and fix tools/generate-operator-out.py. Tidy arena allocation code and arena allocated data types, rather than fixing new and delete operators. Remove dead code. Change-Id: I5b433e722d2f75baacfacae4d32aef4a828bfe1b
* Change Reference.get() intrinsic to Reference.getReferent().Mathieu Chartier2014-09-091-1/+1
| | | | | | | | | | | | | The reference intrinsic was incorrectly inlining PhantomReference.get(). We now get around this by adding a layer of indirection. Reference.get() now calls getReferent() which is intrinsified and inlined. Requires: https://android-review.googlesource.com/#/c/107100/ Bug: 17429865 Change-Id: Ie91e70abf43cedf3c707c7bb8a5059e19d2a2577
* Added support for patching classes from different dex files.Fred Shih2014-08-061-1/+1
| | | | | | | | | Added support for class patching from different dex files and moved ScopedObjectAccess from the quick compiler to driver. Slight refactoring for clarity. Bug: 16656190 Change-Id: I107fcbce75db42ca61321ea1c5d5f236680a1b3d
* AArch64: Add inlining support for ceil(), floor(), rint(), round()Serban Constantinescu2014-08-041-0/+4
| | | | | | | | | | | | | | | This patch adds inlining support for the following Math, StrictMath methods in the ARM64 backend: * double ceil(double) * double floor(double) * double rint(double) * long round(double) * int round(float) Also some cleanup.

* Add intrinsic for Reference.get()Fred Shih2014-07-101-0/+3
| | | | | | | | | | Added an intrinsic function for Reference.get(). Return immediately without going through JNI if the slow path is not currently in use. Otherwise, branch off to the the existing JNI function. Approximately 47x speedup for cases where slow path is not enabled. Change-Id: I13ad65a356fe4e104d8d83980694dc2740d7d039
* ART: Intrinsic implementation for java.lang.System.arraycopy.DaniilSokolov2014-07-081-0/+4
| | | | | | | | | | | | Implements intrinsic for java.lang.System.arraycopy(char[], int, char[], int, int) - this method is internal to android class libraries and used in such classes as StringBuffer and StringBuilder. It is not possible to call it from application code. The intrinsic for this method is implemented as inline method (assembly code is generated manually). The intrinsic is x86 32 bit only.

* Inlining setters that return one of their arguments.Vladimir Marko2014-04-071-1/+1

* Enable annotalysis on clang ART builds.Ian Rogers2014-03-061-1/+0
| | | | | | | | | | | 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
* Fix clang to compile and run host tests.Ian Rogers2014-02-281-5/+6
| | | | | | | | | | | | | | Don't use the computed goto interpreter with clang 3.4 as it causes compilation to hang. Avoid inclusion of LLVM_(HOST|DEVICE)_BUILD_MK except for with portable as it sets clang incompatible cflags. Most fixes are self-evident, for the quick dex file method inliner the enums were being used with ostreams, so fix the enums and operator out python script to allow this. Note this change effects portable but this is untestable as portable was broken by ELF file and mc linker changes. Change-Id: Ia54348f6b1bd3f76d3b71c6e8c5f97626386b903

|/ | | | | | | | | | | | Perform the FastInstance() check for getters and setters when they are detected by the inliner. This will help avoid the FastInstance() check for inlining. We also record the field offset and whether the field is volatile and whether the method is static for use when inlining or generating the special accessors.

* Get rid of platform-specific method inliners.Vladimir Marko2013-12-101-14/+14
| | | | | | | | | | | The DexFileToMethodInlinerMap dependency on CompilerDriver and its instruction set makes it impossible to implement verification-time checking for methods we want to inline. Therefore, we get rid of the platform-specific method inliners and rely on the backend's existing ability to recognize when it can actually emit an intrinsic function.

* Rewrite intrinsics detection.Vladimir Marko2013-11-181-0/+318
Intrinsic methods should be treated as a special case of inline methods. They should be detected early and used to guide other optimizations. This CL rewrites the intrinsics detection so that it can be moved to any compilation phase. Change-Id: I4424a6a869bd98b9c478953c9e3bcaf1c6de2b33
