Andreas Gampe [Fri, 24 Apr 2015 05:23:47 +0000 (22:23 -0700)]
ART: Check for duplicate classes when loading oat files

Oat files are usually produced standalone, and the compilers take
advantage of any information they get. It is thus possible that
when compile-time and runtime class-path are not the same, classes
are resolved differently and optimized code is incorrect.

This is a very conservative check, scanning the complete class tables
of dex files. In case any duplicate class is found, the new oat file
will be rejected and the original dex files will be used in interpreted
mode.

A possible refinement to this is actual tracking of the compile-time
class-path instead. That is however significantly complicated by the
DexFile API and the non-standard uses it allows.

An alternative for both optimized code and correct resolution is
native multidex. Apps should switch to multidex and benefit from
the optimization as well as the shift of all compile time to install
time. Split APKs are currently compiled separately, but it is a goal
to change that install flow to simulated multidex.

Ensure inlined static calls perform clinit checks in Optimizing.

Calls to static methods have implicit class initialization
(clinit) checks of the method's declaring class in
Optimizing.  However, when such a static call is inlined,
the implicit clinit check vanishes, possibly leading to an
incorrect behavior.

To ensure that inlining static methods does not change the
behavior of a program, add explicit class initialization
checks (art::HClinitCheck) as well as load class
instructions (art::HLoadClass) as last input of static
calls (art::HInvokeStaticOrDirect) in Optimizing' control
flow graphs, when the declaring class is reachable and not
known to be already initialized.  Then when considering the
inlining of a static method call, proceed only if the method
has no implicit clinit check requirement.

The added explicit clinit checks are already removed by the
art::PrepareForRegisterAllocation visitor.  This CL also
extends this visitor to turn explicit clinit checks from
static invokes into implicit ones after the inlining step,
by removing the added art::HLoadClass nodes mentioned
hereinbefore.
