5. Show the first few characters of a string.
6. Show the length of a string if we truncate it.

Carl Shapiro [Wed, 8 Jun 2011 04:42:44 +0000 (21:42 -0700)]
Fix two issues with the card table.

Several tricks are used to adjust the base of the card table to save
instructions in the write barrier.  This change corrects two
situtations where the card table did not properly account for the
effects of these tricks.

First, the card table is over allocated to ensure that the start
address can be magically aligned.  When releasing the allocation these
additional bytes were not supplied to munmap creating a potential
leak.

Second, the valid card check did not use the right base address for a
containment check.  The check used the allocation base which is may be
lower than the actual starting address.  This would cause valid cards
at the high end of the heap to be considered invalid and invalid cards
at the low end of the heap to be considered valid.

opcodes are enabled (which is the default, but may be overridden by
targeting an older API level).

Interpreter/Debugger fix #4479968

This one was tricky to track down.  The underlying problem arose
with the consolidation of InterpState with Thread.  Rather than
having a state structure for each instance of the interpreter, we
moved to a model that had a single thread-local struct shared by all
interpreter instances running on that thread.  A portion of interpreter
state can't be shared - and thus was saved and restored on nested
invocations of the interpreter.

The bug here was that the storage for method return values was not
included in the state that needed save/retore.  In normal operation,
it doesn't need to be saved - that storage isn't live across an
invoke that could trigger a nested interpreter activation.  However,
when debugging, the debugger itself may hijack threads and create
new interpreter instances for its own purposed - and there is a small
window in which live retval can be trashed.

The fix is simply to move retval into the InterpSave struct.

Fix alt handling for Jumbo ops

The mterp alt mechanism allows us to break out of the fast
interpreter loop to handle debugging, JIT trace selection and
other non-standard behavior.  It does this by replacing the
base pointer to the instruction handlers with an alternate
base that references a set of dummy handlers that first call
out the dvmCheckBefore() to handle special actions before
routing control to the real handlers.

This mechanism was slightly broken for the Jumbo ops - which
have a first opcode byte of 0xFF (Dispatch), followed by the
Jumbo opcode byte.  In short, when the altHandlerBase was active
dvmCheckBefore() was getting called for both the dispatch opcode
byte and the Jumbo byte.

This change adds special ALT_OP_DISPATCH_FF handlers which skip
the dvmCheckBefore() call.

Type the reference member of JValue as an Object pointer.

Previously this had been a void pointer.  To avoid adding lots of
casts from the logical Object subtypes to Object the RETURN_PTR macro
silently casts its argument to an Object* before performing an
assignment to the JValue return value.  After an inheritance
relationship is established between Object and its subtypes this cast
can be removed.
