ART: Make mterp jit profiling race tolerant
The JIT profiling mechanism is intentionally non-precise to minimize
performance overhead. In general, this is not a problem. However,
the on-stack replacement mechanism assumes an order of method
compilation than can sometimes be violated if conditions are just
right.
This change allows compilation requests that were dropped due to
a race condition to eventually be re-issued. It does this by allowing
the 16-bit hotness counter to wrap around.

ART: Change prebuild run-test setup
Prebuild was meant to check whether the runtime correctly loads
pre-existing oat files. With the advent of patching images, this
has actually been reduced to "does the runtime run self-patchoat"
correctly.
We cannot produce a prebuilt oat file that does not have to be
patched, as the runtime will patch the image when it starts.
There are two options to make this more meaningful:
* In the prebuild setting, first run patchoat to explicitly create
a valid dalvik-cache.
* Change the dex2oat output to be the odex file, which can be
patched like a regular file.
This change shows the latter approach.

ART: Fix race in on-stack replacement
The expected sequence of events for on-stack replacement is:
1. Method goes warm, triggering enhanced profiling
2. Method goes hot, triggering method compilation
3. Method goes really hot, triggering an osr method compilation.
4. Interpreter polls for the existence of an osr entry point,
and transitons to compiled code if found.
We have a race problem if #2 and #3 happen closely together, and
the osr method compilation begins before the regular method
compilation. In that case, the jit sees that the method is
already being compiled (the osr method - but it does not
distinguish the two), and discards the normal compilation request.
So, the osr version is compiled and the normal version is discarded.
In #4, the MaybeDoOnStackReplacement() check assumes that a normal
version of the compiled method must exist before doing an on-stack
replacement, so it keeps returning false.
This is why we were seeing sporadic timeout failures of
570-checker-osr when the mterp fast branch profiling was
introduced. The branch profiling performance enhancements
greatly reduced the time between #2 and #3, increasing the liklihood
of losing the race. Further, the new code clamped hotness to avoid
wrap-around. The race existed (and likely occurred) in the previous
version, but because hotness counters were allowed to overflow and
wrap around you'd eventually hit the threshold a second time and
try again - masking the problem.
Tip 'o the hat to Serguei Katkov for identifying the problem.
A possible solution (taken in this CL) is to differentiate osr
compilations from normal method compilations.

Mathieu Chartier [Tue, 5 Apr 2016 21:36:57 +0000 (14:36 -0700)]
Shard classloader classes lock
Used to guard adding and removing classes.
Previously we used the class linker classes lock, but this had
a deadlock issue since the reference processor may need to acquire
the lock to mark the classes of a class loader. Another thread could
be blocked trying to access weak globals while also holding the
class linker classes lock.

Optimizing: Fix codegens for MethodLoadKind::kDexCacheViaMethod.
Use the original method index instead of the target method
index because the target method may point to a different dex
file.
No regression test: this currently happens only if the
codegen uses the kDexCacheViaMethod as a fallback for
another load kind and we aim to avoid that fallback, so it
would be difficult to write a reliable regression test. We
could try and exploit current fallbacks for irreducible
loops on x86 and arm but those fallbacks will eventually
disappear anyway.
