* [ObjC][CodeGen] Remove an assert that is no longer correct.Akira Hatanaka2016-05-132-4/+27
| | | | | | | | | | | | | | | | | | clang asserts when compiling the following code because r231508 made changes to promote constant temporary arrays and records to globals with constant initializers: std::vector<NSString*> strs = {@"a", @"b"}; This commit changes the code to return early if the object returned by createReferenceTemporary is a global variable with an initializer. rdar://problem/25504992 rdar://problem/25955179 Differential Revision: http://reviews.llvm.org/D20045 llvm-svn: 269385

* dsymutil: Fix the DWOId mismatch check for cached modules.Adrian Prantl2016-05-132-6/+21
| | | | | | | | | | | | | | In verbose mode, we emit a warning if the DWOId of a skeleton CU mismatches the DWOId of the referenced module. This patch updates the cached DWOId after a module has been loaded to the DWOId of the module on disk (instead of storing the DWOId we expected to load). This allows us to correctly emit the mismatch warning for all subsequent object files that want to import the same module. This patch also ensures both warnings are only emitted in verbose mode. rdar://problem/26214027 llvm-svn: 269383

| | | | | | | | | | | | | | This one has a lot of code churn, but it's all mechanical and straightforward. - Where we were returning a node before, call ReplaceNode instead. - Where we would return null to fall back to another selector, rename the method to try* and return a bool for success. - Where we were calling SelectNodeTo, just return afterwards.

* Fix some long standing issues that caused tests to be flaky. Greg Clayton2016-05-1210-216/+323
| | | | | | | | | | | | | | | | | | The main issues were: - Listeners recently were converted over to used by getting a shared pointer to a listener. And when they listened to broadcasters they would get a strong reference added to them meaning the listeners would never go away. This caused memory usage to increase and would cause performance issue if many steps were done. - The lldb_private::Process private state thread had an issue where if a "stop" contol signal was attempted to be sent to that thread, it could end up not responding in 2 seconds and end up getting cancelled which might cause us to cancel a thread that had a mutex locked and it would deadlock the test. This change makes broadcasters hold onto weak references to listeners. It also fixes some bad threading code that had races inside of it by making the m_events_mutex be non-recursive and getting rid of fragile use of a Predicate<bool> to say that new events are available, and replacing it with using the m_events_mutex with a new m_events_condition to control access to the events in a safer way. The private state thread now uses a safer way to communicate that the control event has been received by the private state thread: it makes a EventDataReceipt instance that it attaches to the event that sends the control to the private state thread and used this to synchronize the fact that the private state thread has received the event instead of using a Predicate<bool> to convey the info. When the signal event is received, it will pull the event off of the queue in the private state thread and cause the EventData::DoOnRemoval() to be called, which will signal that the event has been received. This cleans up the signal delivery notification so it doesn't rely on a member variable of the process class to convey the info. std::shared_ptr<EventDataReceipt> event_receipt_sp(new EventDataReceipt()); m_private_state_control_broadcaster.BroadcastEvent(signal, event_receipt_sp); <rdar://problem/26256353> Listeners are being kept around longer than they should be due to recent changs <rdar://problem/26256258> Private process state thread can be cancelled and cause deadlocks in test suite llvm-svn: 269377

| | | | | | | | | | | | | This change adds a new entry point, kmp_aligned_malloc(size_t size, size_t alignment), an entry point corresponding to kmp_malloc() but with the capability to return aligned memory as well. Other allocator routines have been adjusted so that kmp_free() can be used for freeing memory blocks allocated by any kmp_*alloc() routine, including the new kmp_aligned_malloc() routine.

* Fix team reuse with foreign threadsJonathan Peyton2016-05-122-0/+84
| | | | | | | | | | | | | | After hot teams were enabled by default, the library started using levels kept in the team structure. The levels are broken in case foreign thread exits and puts its team into the pool which is then re-used by another foreign thread. The broken behavior observed is when printing the levels for each new team, one gets 1, 2, 1, 2, 1, 2, etc. This makes the library believe that every other team is nested which is incorrect. What is wanted is for the levels to be 1, 1, 1, etc. Differential Revision: http://reviews.llvm.org/D19980 llvm-svn: 269363

* [ARM] Support and tests for transform of LDR rt, = to MOVRenato Golin2016-05-126-13/+391
| | | | | | | | | | | | | | | | | | | | | | | | | | This change implements the transformation in processInstruction() for the LDR rt, =expression to MOV rt, expression when the expression can be evaluated and can fit into the immediate field of the MOV or a MVN. Across the ARM and Thumb instruction sets there are several cases to consider, each with a different range of representatble constants. In ARM we have: * Modified immediate (All ARM architectures) * MOVW (v6t2 and above) In Thumb we have: * Modified immediate (v6t2, v7m and v8m.mainline) * MOVW (v6t2, v7m, v8.mainline and v8m.baseline) * Narrow Thumb MOV that can be used in an IT block (non flag-setting) If the immediate fits any of the available alternatives then we make the transformation. Fixes 25722. Patch by Peter Smith. llvm-svn: 269354
* [ARM] Fixup tests to take into account mov translation. NFC.Renato Golin2016-05-126-56/+56
| | | | | | | | | | | | | Alter instances in the test-suite that use immediates that can be represented in the immediate field of a MOV. The reason for doing this is that when the LDR rt,=imm transformation to MOV rt, imm the existing tests do not need to be modified. Required by the patch that fixes PR25722. Patch by Peter Smith. llvm-svn: 269353
* [ARM] Delay ARM constant pool creation. NFC.Renato Golin2016-05-125-6/+92
| | | | | | | | | | | | | | | | | | | | | This change adds a new constant pool kind to ARMOperand. When parsing the operand for =immediate we create an instance of this operand rather than creating a constant pool entry and rewriting the operand. As the new operand kind is only created for ldr rt,= we can make ldr rt,= an explicit pseudo instruction in ARM, Thumb and Thumb2 The pseudo instruction is expanded in processInstruction(). This creates the constant pool and transforms the pseudo instruction into a pc-relative ldr to the constant pool. There are no functional changes and no modifications needed to existing tests. Required by the patch that fixes PR25722. Patch by Peter Smith. llvm-svn: 269352
