ART: Allow array-ness for unresolved merge types

In case component types aren't resolvable, array types won't be
either. They then may be merged. The merge is still potentially
an array type.

Ensure that merging an unresolved array type with a primitive
array type or a non-array type will be resolved to java.lang.Object.

Added tests.

8 years agoART: Improve JitProfile perf in arm/arm64 mterp
buzbee [Tue, 1 Mar 2016 23:03:16 +0000 (15:03 -0800)]
ART: Improve JitProfile perf in arm/arm64 mterp

ART currently requires two profiling-related things from the
interpreters: hotness updates and OSR switch checks.  The hotness
updates previously used the existing instrumentation framework - which
is flexible, but quite heavyweight.  For most things, the
instrumentation framework overhead is acceptable, but because we do a
hotness update on every backwards branch the overhead is unacceptable.
Prior to this CL, branch profiling dominates interpreter cost.

Here, we bypass the instrumentation framework for hotness updates
and deliver a significant performance improvement.  Running
interpreter-only (dalvikvm -Xint) on a Nexus 6, we see the logic
subtest of Caffeinemark improving from 2600 to 9200, and the
overall score going from 1979 to over 3000.  Compared to the
C++ switch interpreter, we see a 6x improvement on the branchy logic
subtest and a 2.6x improvement overall.

Compared with the previous mterp which did not have support for
jit profiling, we see a few (1% to 5%) performance loss on the
standard command-line benchmarks.  I consider this acceptable
(we could create an alternate non-profiling mterp which would
have no penalty, but I don't consider this overhead big enough to
justify that).
