2015-12-16Detect phi cycles. Nicolas Geoffray
Having reference and non-reference phi equivalent, only happened for the 0/null constant. To avoid such occurences, we must detect phi cycles. bug:25493693 Change-Id: Ie1a8460c3abacca96c299da107fa4407e17dd792

2015-12-15Lower jitthreshold for jit profile test. Calin Juravle
The test still proves to be flacky on the build bots. Lowering the threshold will trigger compilation earlier. Change-Id: Iacabf88d9fbd2a15fd3456f817402c9aaf3ec766
2015-12-15x86 Baker's read barrier fast path implementation. Roland Levillain
Introduce an x86 fast path implementation in Optimizing for Baker's read barriers (for both heap reference loads and GC root loads). The marking phase of the read barrier is performed by a slow path, invoking a new runtime entry point (artReadBarrierMark). Other read barrier algorithms continue to use the original slow path based implementation, which has been renamed as GenerateReadBarrierSlow/GenerateReadBarrierForRootSlow.

2015-12-14ART: Refactor SsaBuilder for more precise typing info David Brazdil
This patch refactors the SsaBuilder to do the following: 1) All phis are constructed live and marked dead if not used or proved to be conflicting. 2) Primitive type propagation, now not a separate pass, identifies conflicting types and marks corresponding phis dead. 3) When compiling --debuggable, DeadPhiHandling used to revive phis which had only environmental uses but did not attempt to resolve conflicts. This pass was removed as obsolete and is now superseded by primitive type propagation (identifying conflicting phis) and SsaDeadPhiEliminiation (keeping phis live if debuggable + env use). 4) Resolving conflicts requires correct primitive type information on all instructions. This was not the case for ArrayGet instructions which can have ambiguous types in the bytecode. To this end, SsaBuilder now runs reference type propagation and types ArrayGets from the type of the input array. 5) With RTP being run inside the SsaBuilder, it is not necessary to run it as a separate optimization pass. Optimizations can now assume that all instructions of type kPrimNot have reference type info after SsaBuilder (with the exception of NullConstant). 6) Graph now contains a reference type to be assigned to NullConstant. All reference type instructions therefore have RTI, as now enforced by the SsaChecker. Bug: 24252151 Bug: 24252100 Bug: 22538329 Bug: 25786318 Change-Id: I7a3aee1ff66c82d64b4846611c547af17e91d260

2015-12-11Replace rotate patterns and invokes with HRor IR. Scott Wakeling
Replace constant and register version bitfield rotate patterns, and rotateRight/Left intrinsic invokes, with new HRor IR. Where k is constant and r is a register, with the UShr and Shl on either side of a |, +, or ^, the following patterns are replaced: x >>> #k OP x << #(reg_size - k) x >>> #k OP x << #-k x >>> r OP x << (#reg_size - r) x >>> (#reg_size - r) OP x << r x >>> r OP x << -r x >>> -r OP x << r Implemented for ARM/ARM64 & X86/X86_64. Tests changed to not be inlined to prevent optimization from folding them out. Additional tests added for constant rotate amounts. Change-Id: I5847d104c0a0348e5792be6c5072ce5090ca2c34

2015-12-10ART: Stash a resolved method late in the verifier Andreas Gampe
Invoke-interface should only be called on an interface method. We cannot move the check earlier, as there are other checks that must be done that can fail a class hard. So postpone a push to the dex cache. Clean up the test a bit. Also templatize ResolveMethod with a version always checking the invoke type, and on a cache miss check whether type target type is an interface when an interface invoke type was given.

2015-12-10Optimizing: Add direct calls to math intrinsics Mark Mendell
Support the double forms of: cos, sin, acos, asin, atan, atan2, cbrt, cosh, exp, expm1, hypot, log, log10, nextAfter, sinh, tan, tanh Add these entries to the vector addressed off the thread pointer. Call the libc routines directly, which means that we have to implement the native ABI, not the ART one. For x86_64, that includes saving XMM12-15 as the native ABI considers them caller-save, while the ART ABI considers them callee-save. We save them by marking them as used by the call to the math function. For x86, this is not an issue, as all the XMM registers are caller-save. Other architectures will call Java as before until they are ready to implement the new intrinsics. Bump the OAT version since we are incompatible with old boot.oat files.

2015-12-10Enable profiled guided compilation in dex2oat Calin Juravle
- add parsing of the profile info saved during JIT. - don't compile methods which are not part of the profile info. - delete old profile hooks. - add test for reading/writing profile. The test is disable in: * interpreter modes: the test needs JIT. * no-dex2oat/no-prebuild: we only save profiling info for the primary oat file. In these modes we don't create oat files and thus nothing is saved. Bug:26080105 Change-Id: Ifdc63dc9d4b537fc79e54c3edc3ae3a462bc30fb

2015-12-10ART: Fix bug in DCE not removing phis from catch phi uses David Brazdil
Due to the missing edges between throwing instructions and catch phis DCE needs to manually remove dead instructions from catch phi users, being overly conservative if the inputs are not in the dead blocks. DCE used to do this for normal instructions, but it needs to do the same for phis. Change-Id: I7edfcb84ec6ff7303945d5d5cd436b1d1e95df2a

Invoke-interface should only be called on an interface method. Move the check earlier, as otherwise we'll try to resolve and potentially inject a method into the dex cache. Also templatize ResolveMethod with a version always checking the invoke type, and on a cache miss check whether type target type is an interface when an interface invoke type was given.
