| | | | Change-Id: Ibe0efa4e84fd020a53ded310a92e0b4363f91b12
* Initiate a constant propagation pass in the optimizing compiler.Roland Levillain2014-09-181-0/+1
| | | | | | | | - Perform constant folding on int and long additions and subtractions in the optimizing compiler. - Apply constant folding to conditions and comparisons. Change-Id: Ic88783a3c975fda777c74c531e257fa777be42eb

* Add CFG and SSA form checkers in the optimizing compiler.Roland Levillain2014-09-171-0/+1
| | | | | | | | | | | | | | | | | Checks performed on control-flow graphs: - Ensure that the predecessors and successors of a basic block are consistent within a control-flow graph. - Ensure basic blocks end with a branch instruction. - Detect phi functions listed in non-phi instruction lists and vice versa. - Ensure a block's instructions (and phi functions) are associated with this very block. Checks performed on SSA form graphs: - Ensure an instruction dominates all its uses. - Ensure there are no critical edges. Change-Id: I1c12b4a61ecf608682152c897980ababa7eca847

* Implement suspend checks in new compiler.Nicolas Geoffray2014-09-151-0/+1
| | | | | | | For simplicity, they are currently placed on all (dex-level) back edges, and at method entry. Change-Id: I6e833e244d559dd788c69727e22fe40aff5b3435
* Fix valgrind errors.Nicolas Geoffray2014-09-111-9/+0
| | | | | | | | For now just stack allocate the code generator. Will think about cleaning up the root problem later (CodeGenerator being an arena object). Change-Id: I161a6f61c5f27ea88851b446f3c1e12ee9c594d7
* ART: Fix things for valgrindAndreas Gampe2014-09-102-1/+20
| | | | | | | | | | | | | | | | | | | | | | Wire up valgrind gtests. Add valgrind-test-art-host, currently only depending on valgrind-test-art-host-gtest32. Fix an Alloc setting to allow running valgrind. Refactor the fault handler to manage (and correctly release) the handlers. Fix minor failure-case leaks exposed by tests. Failing tests: The optimizing compiler is leaking non-arena-ed structures (e.g., assembler buffers), as code generators are not destroyed. The solution has been moved to a follow-up CL. Note: All 64b tests are failing as we cannot allocate a heap. Change-Id: I7f854cfd098d9f68107ce492363e7dba9a82b9fa
* Really fix tests.Alex Light2014-08-271-1/+3
| | | | | | | | | | | | Remove extra line in Android.run-test.mk. Update junit code in 082 and 021. Set correct bootclasspath for --no-image. Make host core.art depend on dex files being installed. Make 118 pass in the correct bootclasspath. Bug: 17290452 Change-Id: I415eddfa3632ec7eda927abe95925202de193749
* Add run-test support for running without a working patchoat/dex2oatAlex Light2014-08-261-0/+9
| | | | | | | | Also add it to the test-art target. Bug: 17262039 Change-Id: Id31130194c46df66fc48852d6f8884f14cb08db4
* Use loops to build combinations of run-tests.Ian Rogers2014-08-261-8/+11
| | | | | | | | | | Add a JNI force copy test. Split tracing from GC, relocation from prebuilding. As the combinations of tests is sufficiently large to cause make serious work, only build rules for tests that will be executed. Default to small number of tests rather than full. Use ART_TEST_FULL=true to override. Change-Id: Ic25431f29071b840d2e2295be6853511c0b52cfa
* ART: Add dex dependency for gtestAndreas Gampe2014-08-211-1/+1
| | | | Change-Id: I22d5e9b69e40585c6ee57381ee758b4b32e07f96
* ART: Set default visibility to protectedAndreas Gampe2014-08-191-1/+2
| | | | | | | | | | | | | | | Set default visibility of symbols to protected. This allows the linker to optimize internal calls and helps avoid plt calls. Make almost all assembly stubs hidden, as -fvisibility does not seem to apply to them. Change the assembly tests accordingly. Also allows to clean up previous hacks to avoid plt calls. Bug: 16974467 (cherry picked from commit 235e77bd9f19e4faefda109be40f8744f3a66f40) Change-Id: I9030dcf6116251f434f94a2b08e56e12085af652
* Really fix target gtest dependenciesBrian Carlstrom2014-08-181-2/+2
| | | | | | | | In 64006834b26f7138131fac87c3b0973cda70e560 we started depending on TARGET_CORE_JARS which are phony targets and undefined when using "mm test-art-target". Change-Id: I671c5d6068ff999782ad5f388f3077f4c1594884

* Add --always-clean flag to run-test.Alex Light2014-07-301-0/+3
| | | | | | | | | This flag makes run-test remove the test-artifacts even if it fails. Also enable this option by default when doing run-tests with make. Add a ART_TEST_RUN_TEST_ALWAYS_CLEAN environment variable to control this option. Change-Id: I7867b400d570d8d679d9822d1fa65f49eb3522ae

| * Add a new stack map scheme that encodes compilation info per pc.Nicolas Geoffray2014-07-211-0/+1
| | | | | | | | | | | | | | | | Encodes stack mask, register mask, dex register values, and inlining info. The encoding is currently very straightforward: there is no clever encoding, nor compression. Change-Id: I5fd9ae28189a5513cd9e3c8d52c648463207643d

| |/ | | | | | | | | | | | | | | | | | | Bug: 16362912 The latest version of clang is generating larger frames on elf_writer_quick.cc and dex2oat.cc than we had previously encountered. This change unblocks the LLVM rebase temporarily. Change-Id: I20d9f88959b91e0509e58f01c22532720225f44d

* | Rewrite topological sort order and improve GVN.Vladimir Marko2014-07-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rewrite the topological sort order to include a full loop before the blocks that go after the loop. Add a new iterator class LoopRepeatingTopologicalSortIterator that differs from the RepeatingTopologicalSortIterator by repeating only loops and repeating them early. It returns to the loop head if the head needs recalculation when we reach the end of the loop. In GVN, use the new loop-repeating topological sort iterator and for a loop head merge only the preceding blocks' LVNs if we're not currently recalculating this loop. Also fix LocalValueNumbering::InPlaceIntersectMaps() which was keeping only the last element of the intersection, avoid some unnecessary processing during LVN merge and add some missing braces to MIRGraph::InferTypeAndSize().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
