Make Release(JNI_COMMIT) faster

The Release<primitive>ArrayElements and ReleasePrimitiveArrayCritical
calls take a "mode" argument.  If you pass in JNI_COMMIT, the storage
isn't actually released; instead, the buffer contents are flushed to
the backing storage.  If the VM has handed you a pointer to the raw
data rather than a copy, the call is a no-op.

In its present incarnation, it's a no-op that changes the thread state,
adding overhead and the possibility of suspension.  This change moves
the test for JNI_COMMIT outside the enter/exit macros.

Added JNI hack to support JNI hack

Some of our graphics code wants to get a pointer, release it, and then
continue to use it.  The "forcecopy" mode of CheckJNI was designed
to find any code that does this.  It succeeded.

To support the behavior, we provide a JNI helper function that does
the dirty work.  It passes a magic value into the Get and Release calls
that causes "forcecopy" to skip the copy.  When forcecopy is not
enabled, the values are simply ignored.

To avoid any possibility of the function getting published in the NDK,
the function is not described in JNIHelp.h.

13 years agoEnsure word atomicity in System.arraycopy
Andy McFadden [Thu, 3 Feb 2011 00:55:41 +0000 (16:55 -0800)]
Ensure word atomicity in System.arraycopy

The VM needs to ensure that updates to 16-bit and 32-bit fields
and array elements happen atomically.  System.arraycopy was calling
memmmove(), which in bionic happens to copy a byte at a time.

The new plan is to have bionic provide a platform-optimized memmove
variant that makes guarantees about word sizes.  If it is not present
(either because it hasn't been written for the current platform,
or we're not linking against bionic), we will use a trivial copy loop.

We assume that the memmove-by-word implementation does whatever
it needs to for best performance.  For example, if the function
determines that memcpy() is word-safe and will be faster, it can
call that.  The VM no longer makes assumptions about the internal
workings of libc functions.

I also rearranged the code to avoid making indirect calls, reading
function addresses from memory, and using integer multiplication
instructions when a simple shift will do.  (gcc now generates the
whole thing as one function.)

Also, added some primitive array copy tests to 011-array-copy.

Replace collect with clear for the SoftReference policy.

The garbage collector is invoked with a parameter that changes the
SoftReference clearing policy.  This parameter is normally false,
meaning the garbage collector will attempt to preserve some
softly-reachable referents of SoftReference instances.  When true, the
garbage collector will treat SoftReference instances as WeakReference
instances and always clearly referent fields with softly-reachable
referents.

The code refers to this action as collecting soft references which is
misleading.  The change to the garbage collector policy has an effect
on the referent field of SoftReference instances and any SoftReference
instance which is unreachable is subject collection like any other
object.  With this change we now use the description clearing soft
refernces to describe the policy.

Change suspend order in GC

The GC currently does this:

 1. acquire heapLock
 2. suspend all threads
 3. acquire heapWorkerLock

When the HeapWorker thread is suspended in #2, it might be holding
the lock we want in step #3, leading to VM deadlock.  This change
reverses the order of #2 and #3, which should allow the HeapWorker
thread to progress to a point where it releases the lock before
the GC requests the suspension.

If futexes are being unfair, the GC might have to wait a bit
longer while the HeapWorker does stuff (it might unlock, do work,
and re-lock without the scheduler giving time to the GC thread;
with the old scheme the HeapWorker would see the pending thread
suspension immediately and stop).  A better fix is planned.

Fix JNI invocation of constructors.

The code that "virtualizes" method invocations was attempting to
virtualize a call to a constructor.  Constructors are direct methods,
so this resulted in a spurious CloneNotSupportedException.
