2016-05-13Fix misc-macro-parentheses warnings. Chih-Hung Hsieh
* Add parentheses to fix warnings. * Use NOLINT to suppress wrong clang-tidy warnings. Bug: 28705665 Change-Id: Icc8bc9b59583dee0ea17ab83e0ff0383b8599c3e
2015-11-24Revert "lambda: Add support for invoke-interface for boxed innate lambdas" Nicolas Geoffray
955-lambda is flaky Bug: 24618608 Bug: 25107649 This reverts commit 457e874459ae638145cab6d572e34d48480e39d2. Change-Id: I24884344d21d7a4262e53e3f5dba57032687ddb7
2015-11-20lambda: Add support for invoke-interface for boxed innate lambdas Igor Murashkin
Lambda closures created with the 'create-lambda' instruction (termed "innate lambdas") can be turned into an object with 'box-lambda'. This CL enables support for those kinds of lambdas to work with 'invoke-interface' by generating a proxy class for the lambda. Note: MIPS32/64 support not included.

2015-09-27Revert "lambda: Experimental support for capture-variable and liberate-variable" Nicolas Geoffray
Test fails. This reverts commit b72123440d8541362ebdb131436f9dbdda5fd329. Change-Id: Ic9ed92f8c826d8465eb36b746dc44af05caf041c
2015-09-25lambda: Experimental support for capture-variable and liberate-variable Igor Murashkin
Supports capturing/liberating any primitive variables. No support for capturing objects/lambdas yet since they would both need GC changes to track roots through closures. Change-Id: Ibfb68bfe4c579dbf93823aac4c0e6ac8f6360c5d
2015-09-04Fix the read barrier config build. Hiroshi Yamauchi

2015-09-04Merge "lambda: Infrastructure to support capture/liberate-variable dex opcodes" Igor Murashkin
2015-09-03lambda: Infrastructure to support capture/liberate-variable dex opcodes Igor Murashkin
* ArtLambdaMethod - wrap an ArtMethod with extra runtime lambda info * Closure - data representation for a runtime lambda closure (read-only) * ClosureBuilder - writer for creating a Closure at runtime * ShortyFieldType - char/enum wrapper for shorty_field_type in dex Tests: * Closure, ClosureBuilder, ShortyFieldType have full unit test coverage. * ArtLambdaMethod does not, but it is tested indirectly and is otherwise trivial getters. Future CLs will include interpreter integration with minimal changes to this Closure infrastructure. Change-Id: I38a7aea8df1da7b154fd6623258c6c228c8e51df
2015-09-03Some fixes for the CC collector. Hiroshi Yamauchi
- Remove a DCHECK in DisableMarkingCheckpoint, which caused occasional (false) failures. - Check the thread-local GetWeakRefAccessEnabled in boxed lambdas weak access. - Add missing BroadcastForNewAllocationRecords and BroadcastForNewWeakBoxedLambdas. The lack of the former caused occasional deadlocks in the ddmc test. - Remove the 'ensure system weaks disallowed' calls, which weren't useful and dead.

2015-08-04Revert "cleanup: Replace pointers with out-parameters and fix-up formatting" Igor Murashkin
This reverts commit a315f5c546b796f55f4872bb6efc15eb858d9639. -- Revert "runtime: cleanup class_linker out-parameters and formatting" This reverts commit bc1d78daa463572c5a770cdca858a3b51d8e1b7b. -- Revert "base: replace raw pointers for out-parameters with safer out<T>" This reverts commit fb326cffc679cab8eb873b9e44795706f023cb3c.
2015-07-30base: replace raw pointers for out-parameters with safer out<T> Igor Murashkin
Add a zero-cost type-safe abstraction for representing "out" parameters (i.e. when the calling function has to return multiple results out by-reference into the argument slots instead of using the return slot). Change-Id: I33a941e4863b6bed71d2bfa43d7f48e9b111f83f
2015-07-22Move to newer clang annotations Mathieu Chartier
Also enable -Wthread-safety-negative. Changes: Switch to capabilities and negative capabilities. Future work: Use capabilities to implement uninterruptible annotations to work with AssertNoThreadSuspension. Bug: 20072211 Change-Id: I42fcbe0300d98a831c89d1eff3ecd5a7e99ebf33
2015-07-20runtime: Add lambda box/unbox object equality Igor Murashkin
A lambda that is boxed with box-lambda is now stored as a weak reference in a global runtime table (lambda::BoxTable). Repeatedly boxing the same lambda closure value will always return the same java.lang.Object back. Since there is no way to observe the address of an object, a GC can happen and clean up the table of any dead boxed lambdas, which can also shrink the table to prevent the memory use from growing too much. (Note that a lambda closure is immutable, so hashing over it is guaranteed safe.) Change-Id: I786c1323ff14eed937936b303d511875f9642524
