Merge "Do allocation fence before pushing on allocation stack" into nyc-mr1-dev
Mathieu Chartier [Mon, 18 Jul 2016 18:11:45 +0000 (11:11 -0700)]
Do allocation fence before pushing on allocation stack
Heap::VisitObjects relies on having valid classes for objects in
the allocation stack. If the writes reorder, the thread calling
VisitObjects could see the free list pointer instead of the class
of the object. I believe this is causing crashes in VisitObjects.

Due to AOT and compiling classes that are not ready yet
(eg missing a super class), we need to be conservative when
accessing fields and can end up in a situation where the same

(because of inlining). Therefore, disable removing loads and

27521545
We were hitting a compiler DCHECK that a class would never require to
do access checks on itself. The reason was that the compiler driver
was not trying to resolve a type, but instead relied on the verifier
for pre-populating the dex cache. However, the verifier doesn't
necessarily run in JIT mode.

ART: ArrayGet hoisting restriction added.
Currently if we hoist ArrayGet from loop there is no guarantee
that insn will be executed at runtime. Because of that we could
face issues like crashes in generated code.
This patch introduces restriction for ArrayGet hoisting. We say
that ArrayGet execution is guaranteed at least one time if its bb
dominates all exit blocks.

Hold dex caches live in class table
Prevents temporary dex caches being unloaded for the same dex file.
Usually this is OK, but if someone resolved a string in that dex
cache, it could leave stale pointers in BSS. Also it can use extra
memory in linear alloc if we allocate dex cache arrays multiple
times.

Delay dex-to-dex compilation until Optimizing is done.
This fixes a race between inlining in the Optimizing
backend and dex-to-dex quickening where the Optimizing can
read the non-quickened opcode and then the quickened field
index or vtable index and look up the wrong field or method.
Even if we such tearing of the dex instruction does not
happen, the possible reordering of dex-to-dex and Optimizing
compilation makes the final oat file non-deterministic.
Also, remove VerificationResults::RemoveVerifiedMethod() as
we have only the Optimizing backend now and as such it was
dead code and would have interfered with this change.

Fix race with host_dlopen_handles_
Thread 1 opens an already opened oat file.
Thread 2 dlcloses the oat file and removes it from
host_dlopen_handles_.
Thread 1 checks that it is not already in host_dlopen_handles_ and
proceeds to return the oat file. The problem now is that the BSS is
not cleared since it is the same oat file that was opened earlier.
The fix is to just hold the lock for dlopen / dlclose. This only
affects contention on host.
