Joel Dice	7ea6036842	fix isThunkUnsafeStack ... This function was broken in two different ways: 1. It only checked MyProcessor::thunks, not MyProcessor::bootThunks. It needs to check both. 2. When checking MyProcessor::thunks, it used fields from MyProcessor::bootThunks instead of from the same thunk collection. This fixes both problems.	2010-06-16 20:29:41 -06:00

Joel Dice	9559aca825	fix Thread.getStackTrace race conditions ... Implementing Thread.getStackTrace is tricky. A thread may interrupt another thread at any time to grab a stack trace, including while the latter is executing Java code, JNI code, helper thunks, VM code, or while transitioning between any of these. To create a stack trace we use several context fields associated with the target thread, including snapshots of the instruction pointer, stack pointer, and frame pointer. These fields must be current, accurate, and consistent with each other in order to get a reliable trace. Otherwise, we risk crashing the VM by trying to walk garbage stack frames or by misinterpreting the size and/or content of legitimate frames. This commit addresses sensitive transition points such as entering the helper thunks which bridge the transitions from Java to native code (where we must save the stack and frame registers for use from native code) and stack unwinding (where we must atomically update the thread context fields to indicate which frame we are unwinding to). When grabbing a trace for another thread, we determine what kind of code we caught the thread executing in and use that information to choose the thread context values with which to begin the trace. See MyProcessor::getStackTrace::Visitor::visit for details. In order to atomically update the thread context fields, we do the following: 1. Create a temporary "transition" object to serve as a staging area and populate it with the new field values. 2. Update a transition pointer in the thread object to point to the object created above. As long as this pointer is non-null, interrupting threads will use the context values in the staging object instead of those in the thread object. 3. Update the fields in the thread object. 4. Clear the transition pointer in the thread object. We use a memory barrier between each of these steps to ensure they are made visible to other threads in program order. See MyThread::doTransition for details.	2010-06-15 19:10:48 -06:00

Eric Scharff	9909c0cec3	Fix Mac OS X specific path bug ... In Mac OS X, if a path contains a space, the path of the main executable will contain a special URL-encoded character (%20 in this case). This probably happens when any non-ASCII character is provided. The fix is to use CFURLCreateStringByReplacingPercentEscapes which creates a path that the POSIX API likes better.	2010-04-26 10:24:53 -06:00

Joel Dice	3e5b2cbc7b	fix miscompilation of 64-bit volatile field reads and writes on x86_32 ... We were generating code which clobbered the data we were putting into 64-bit volatile fields (and potentially also clobbering the target or source object in the case of non-static fields) due to misplaced synchronization code. Reordering this code ensures that both the data and the target or source survive across calls to synchronization helper functions.	2010-03-01 18:24:25 -07:00
Joel Dice	c2a9424f91	implement compileTimeMemoryBarrier in arch.h ... This has the same implementation as programOrderMemoryBarrier in x86.h, but makes it available on all architectures.	2010-02-04 18:30:13 -07:00
Joel Dice	99bb7924b0	fix stack frame mapping code for exception handlers ... Previously, the stack frame mapping code (responsible for statically calculating the map of GC roots for a method's stack frame during JIT compilation) would assume that the map of GC roots on entry to an exception handler is the same as on entry to the "try" block which the handler is attached to. Technically, this is true, but the algorithm we use does not consider whether a local variable is still "live" (i.e. will be read later) when calculating the map - only whether we can expect to find a reference there via normal (non-exceptional) control flow. This can backfire if, within a "try" block, the stack location which held an object reference on entry to the block gets overwritten with a non-reference (i.e. a primitive). If an exception is later thrown from such a block, we might end up trying to treat that non-reference as a reference during GC, which will crash the VM. The ideal way to fix this is to calculate the true interval for which each value is live and use that to produce the stack frame maps. This would provide the added benefit of ensuring that the garbage collector does not visit references which, although still present on the stack, will not be used again. However, this commit uses the less invasive strategy of ANDing together the root maps at each GC point within a "try" block and using the result as the map on entry to the corresponding exception handler(s). This should give us safe, if not optimal, results. Later on, we can refine it as described above.	2010-02-04 18:03:32 -07:00
Joel Dice	c9b9db1621	reimplement Java object monitors (second try) ... See commit 8120bee4dc for the original problem description and solution. That commit and a couple of related ones had to be reverted when we found they had introduced GC-safety regressions leading to crashes. This commit restores the reverted code and fixes the regressions.	2010-02-04 17:56:21 -07:00
Joel Dice	48834be209	revert recent commits to reimplement Java object monitors ... We're seeing race conditions which occasionally lead to assertion failures and thus crashes, so I'm reverting these changes for now: 29309fb414 e92674cb73 8120bee4dc	2010-02-04 08:18:39 -07:00

Joel Dice	e92674cb73	fix race condition in monitorWait ... We don't want to check Thread::waiting until we have re-acquired the monitor, since another thread might notify us between releasing Thread::lock and acquiring the monitor.	2010-02-02 12:24:05 -07:00
Joel Dice	3bc37d6e2a	fix encoding of single byte register-to-memory moves on x86_64 ... We need to prefix instructions of the form "mov R,M" with a REX byte when R is %spl, %bpl, %sil, or %dil. Such moves are unencodable on 32-bit x86, and, because of the order in which we pick registers, pretty rare on 64-bit systems, which is why this took so long to notice.	2010-02-02 11:37:08 -07:00
Joel Dice	8120bee4dc	reimplement Java object monitors to avoid running out of OS handles ... Due to SWT's nasty habit of creating a new object monitor for every task added to Display.asyncExec, we've found that, on Windows at least, we tend to run out of OS handles due to the large number of mutexes we create between garbage collections. One way to address this might be to trigger a GC when either the number of monitors created since the last GC exceeds a certain number or when the total number of monitors in the VM reaches a certain number. Both of these risk hurting performance, especially if they force major collections which would otherwise be infrequent. Also, it's hard to know what the values of such thresholds should be on a given system. Instead, we reimplement Java monitors using atomic compare-and-swap (CAS) and thread-specific native locks for blocking in the case of contention. This way, we can create an arbitrary number of monitors without creating any new native locks. The total number of native locks needed by the VM is bounded instead by the number of live threads plus a small constant. Note that if we ever add support for an architecture which does not support CAS, we'll need to provide a fallback monitor implementation.	2010-02-01 18:40:47 -07:00
Joel Dice	45476eb591	fix handling of volatile longs and doubles on PowerPC ... We were miscompiling methods which contained getfield, getstatic, putfield, or putstatic instructions for volatile 64-bit primitives on 32-bit PowerPC due to not noticing that values in registers are clobbered across function calls. The solution is to create a separate Compiler::Operand instance for each object monitor reference before and after the function call to avoid confusing the compiler. To avoid duplicate entries in the constant pool, we add code look for and, if found, reuse any existing entry for the same constant.	2010-01-27 17:46:04 -07:00

Joel Dice	4c0ede8b9a	reuse JNI references when possible ... Before allocating a new reference in NewGlobalReference or when creating a local reference, we look for a previously-allocated reference pointing to the same object. This is a linear search, but usually the number of elements in the reference list is small, whereas the memory, locking, and allocation overhead of creating duplicate references can be large.	2009-12-16 19:16:51 -07:00

Joel Dice	3787985b25	implement basic finalization support ... This implementation does not conform to the Java standard in that finalize methods are called from whichever thread happens to be garbage collecting, and that thread may hold locks, whereas the standard guarantees that finalize will be run from a thread which holds no locks. Also, an object will never be finalized more than once, even if its finalize method "rescues" (i.e. makes reachable) the object such that it might become unreachable a second time and thus a candidate for finalization once more. It's not clear to me from the standard if this is OK or not. Nonwithstanding the above, this implementation is useful for "normal" finalize methods which simply release resources associated with an object.	2009-07-21 18:57:55 -06:00

Joel Dice	47ab980550	fix thread heap overflow corner case in allocate3 ... The previous code relied on the invalid assumption that the thread-local heaps for all threads would have been cleared immediately following a garbage collection. However, the last thing the garbage collection function does is run finalizers which may allocate new objects. This can lead allocate3 to call allocateSmall with a size which is too large to accomodate, overflowing the heap. The solution is to iterate until there really is enough room for the original allocation request.	2009-07-17 19:37:46 -06:00

Joel Dice	dba72409aa	move use of SingleRead::successor; fix build errors ... We now use SingleRead::successor in pickTarget, where we use it to determine the prefered target site for the successor without requiring the target to conform to that preference.

Joel Dice	35d1c6e068	add SingleRead::successor; fix build errors ... The SingleRead::successor field is used (when non-null) to further constrain the SiteMask in SingleRead::intersect based on reads of successor values (as in the cases of moves and condensed-addressing combine and translate instructions).	2009-04-06 18:34:12 -06:00
Joel Dice	fea92ed995	more work on tail recursion ... We now create a unique thunk for each vtable position so as to avoid relying on using the return address to determine what method is to be compiled and invoked, since we will not have the correct return address in the case of a tail call. This required refactoring how executable memory is allocated in order to keep AOT compilation working. Also, we must always use the same register to hold the class pointer when compiling virtual calls, and ensure that the pointer stays there until the call instruction is executed so we know where to find it in the thunk.	2009-04-05 15:42:10 -06:00

Thread B calls function F, sees that it's already been compiled and so runs it. 3. Thread B calls function G from function F, and G needs to be compiled, but it needs to acquire the class lock first, which A owns. 4. Thread A causes a GC, walks thread B's stack, but function F has not yet been added to the method tree, so it thinks the stack has no frames. 5. Thread A finally adds function F to the method tree. 6. Thread A causes another GC and walks thread B's stack again, and this time it finds function F in the method tree. 7.
