| * Fix and improve shift and rotate operations.Roland Levillain2016-03-229-119/+141
| | | | | | | | | | | | | | | | | | | | | | | | - Define maximum int and long shift & rotate distances as int32_t constants, as shift & rotate distances are 32-bit integer values. - Consider the (long, long) inputs case as invalid for static evaluation of shift & rotate rotations. - Add more checks in shift & rotate operations constructors as well as in art::GraphChecker.

| * | Ensure object ArraySet with null value does not need a type check.Roland Levillain2016-03-233-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The art::PrepareForRegisterAllocation visitor can remove an art::BoundType instruction as value input of an art::ArraySet instruction, possibly replacing it with an art::NullConstant. If this happens, remove the need for a type check in this art::ArraySet. Bug: 27638110 Change-Id: I6270f8a8e22822a24d8a5919df427ca9c64d121b

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bots are red. Tentative reverting as this is likely the offender. Bug: 27689078 This reverts commit a62d2f04a6ecf804f8a78e722a6ca8ccb2dfa931. Change-Id: I3ec6947a5a4be878ff81f26f17dc36a209734e2a
* | | | Use compiler filter to determine oat file status.Richard Uhler2016-03-222-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Record the compiler filter in the oat header. Use that to determine when the oat file is up-to-date with respect to a target compiler filter level. New xxx-profile filter levels are added to specify if a profile should be used instead of testing for the presence of a profile file. This change should allow for different compiler-filters to be set for different package manager use cases. Bug: 27689078 Change-Id: Id6706d0ed91b45f307142692ea4316aa9713b023

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove unused allocation types, mostly from removed Quick. Move logging one level up to capture memory used by stack maps during AOT compilation. Raise the reporting threshold to 8MiB to limit the output to the worst offenders.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | Rationale: This changelist implements allowing narrowing conversions within inductions and loop control. More induction and loops recognized, more bounds eliminated. We all win. The basic idea is pretty simple (record type with detected induction) but one has to get all the details right, as illustrated by the many new unit tests.
