2015-02-23Add JIT Mathieu Chartier
Currently disabled by default unless -Xjit is passed in. The proposed JIT is a method JIT which works by utilizing interpreter instrumentation to request compilation of hot methods async during runtime. JIT options: -Xjit / -Xnojit -Xjitcodecachesize:N -Xjitthreshold:integervalue The JIT has a shared copy of a compiler driver which is accessed by worker threads to compile individual methods. Added JIT code cache and data cache, currently sized at 2 MB capacity by default. Most apps will only fill a small fraction of this cache however. Added support to the compiler for compiling interpreter quickened byte codes. Added test target ART_TEST_JIT=TRUE and --jit for run-test. TODO: Clean up code cache. Delete compiled methods after they are added to code cache. Add more optimizations related to runtime checks e.g. direct pointers for invokes. Add method recompilation. Move instrumentation to DexFile to improve performance and reduce memory usage. Bug: 17950037 Change-Id: Ifa5b2684a2d5059ec5a5210733900aafa3c51bca

2014-11-24Eliminate suspend checks on back-edges to return insn. Vladimir Marko
This optimization seems to have been broken for a long time. Change-Id: I62ec85c71bb5253917ad9465a952911e917f6b52
2014-11-21Rewrite GVN's field id and field type handling. Vladimir Marko
Create a helper unit for dex insn classification and cache dex field type (as encoded in the insn) in the MirFieldInfo. Use this for cleanup and a few additional DCHECKs. Change the GVN's field id to match the field lowering info index (MIR::meta::{i,s}field_lowering_info), except where multiple indexes refer to the same field and we use the lowest of the applicable indexes. Use the MirMethodInfo from MIRGraph to retrieve field type for GVN using this index. This slightly reduces GVN compilation time and prepares for further compilation time improvements.
