buzbee [Thu, 23 Jun 2016 20:35:39 +0000 (13:35 -0700)]
ART: Add Mterp export pc poison testing mode

One of the optimizations of the Mterp assembly interpreter is
that it attempts to limit the number of times it updates the saved
dex_pc_ value stored in the shadow frame.  Instead, it maintains
a pointer to the current dex instruction in a dedicated register.

However, whenever execution flow exits the immediate mterp
environment and some other part of the runtime needs to know the
current dex pc (for example - exception throws), mterp must
save - or "export" the dex_pc back into it's home location in
the shadow frame.

Forgetting to do this is a typical bug when developing mterp
instruction handlers.  And, the failures show up in odd and
sometimes hard to track down ways.  This CL adds a testing mode
that poisons the saved dex_pc prior to each instruction
interpretation.  Thus, if any individual handler neglects to
properly export the current dex pc and then goes on to use it
we'll segfault out with an identifiable fault address: 0xdead00ff.

TEST: test-art-target (Nexus 5x, Nexus 6p), test-art-host.  Verified
expected failure by artificially neglecting an EXPORT_PC.

ART: Add very-large threshold to dex2oat

Add a variable threshold to dex2oat. If the total dex file size for
an app reaches this threshold, dex2oat will punt all compilation and
compile the app with verify-at-runtime. This ensures smaller compile
time and memory thrashing, while still extracting the dex files and
thus helping with dirty memory later.

Added tests.

GC doesn't gray immune space objects except when visiting the thread

FillWithDummyObject(). GC updates the fields of immune space objects

Improvements in induction range analysis.

Rationale:
Uses range analysis while determining whether trip-counts
are "safe", which improves analysis of triangular loops.
Also implements more effective triangular loop analysis
by evaluating induction information only once and using
a top level hint (instead of the "iterative refinement"
that was used earlier). Also fixes analysis of triangular
trip counts that may wrap-around. All with tests.
