2015-08-08Fix a bug in the register allocator around pair allocation. Nicolas Geoffray
We may get hints that do not work with the current implementation of register pairs, which forces the allocation of (low + 1) for the high register. For example, if the hint is EBX, we will allocate ESP for the high register. bug:23043730 (cherry picked from commit f29758111e71a7d14f3e52d78773561a5d59961f) Change-Id: Ib395e36616017a87d3055218d72417f4e9ff6501

2015-08-05ART: x86_64 RoundDouble/Float intrinsics should initialize out value. Pavel Vyssotski

2015-07-27Bugfix: Java char is 16 bits, can not be treated as boolean. Fredrik Roubert

2015-07-23ART: Fix Quick/Optimizing suspend check assumption mismatch. Vladimir Marko
Quick's SuspendCheckElimination (SCE) expects that every method contains a suspend check and it eliminates suspend checks in loops containing an invoke. Optimizing eliminates the suspend check from leaf methods, so the combination of a Quick-compiled loop calling an Optimizing-compiled leaf method can lead to missing suspend checks and potentially leading to ANRs. Enable Quick's kLeafOptimization flag to remove suspend checks from leaf methods and disable Quick's SCE. This aligns the suspend check placement for the two backends and avoids the broken combination. Currently, all methods containing a try-catch are compiled with Quick, so it's relatively easy to create a regression test. However, this test will not be valid when Optimizing starts supporting try-catch.

2015-07-09Support compiling run-tests with jack Sebastien Hertz
This CL adds support to compile run-test source files with jack. When a test needs to rely on class files, we use jill to convert them to a jack library. We need to pass the full classpath to jack containing at least core classes (like java.lang.Object). This means the Android tree must have been compiled with jack first so we find all the necessary classes.jack files. Some tests still rely on dex files generated with the old toolchain. We keep building them this way for the moment and will update them later, when they get ready for Jack. Also updates a few tests dealing with garbage collection to avoid a situation where a reference can be retained by a local DEX register.
