On Mac, the monotonic clock is not available -- Qt fakes monotonic support by using the Mach timebase -- so we need to use gettimeofday.

* Move QRecursiveMutexPrivate to qmutex.cpp and mark inlineThiago Macieira2012-09-141-12/+0
| | | | | | | | | | | | | | | | | Disassembly of the optimised code shows that the compiler was already inlining the bodies of one or both functions (since they're in the same .cpp, it's allowed to do that). However, since there was no "inline" marker, the compiler was also emitting an out-of-line copy, which wasn't used by anyone, as the class is not exported. So add the marker. To make sure that they don't get used by accident elsewhere, the class is moved to the .cpp file too.

* Make QBasicMutex be exclusively non-recursiveThiago Macieira2012-09-141-0/+1
| | | | | | | | | | | | | | | Dispatch to the recursive mutex functions from QMutex::lock, tryLock and unlock. This has the benefit that those using QBasicMutex will not go through the testing for recursive mutexes. It simplifies a little the code for those users. For the users of QMutex, the code required to perform a lock does not appear to change. Change-Id: I0ca9965e012b283c30f1fab8e9f6d9b3288c2247 Reviewed-by: Lars Knoll <lars.knoll@nokia.com>
* Mark mutex locking and unlocking functions with noexceptThiago Macieira2012-08-251-4/+4
| | | | | | | | | | | | | | | | | | | | | Unlocking a mutex can never throw an exception. That doesn't make sense and our code should make sure it can't happen. Right now, provided that the system-level functions don't throw, we don't either. Locking a mutex cannot throw on Linux because we use futexes directly. A non-recursive mutex is just a futex, whereas a recursive mutex uses a mutex (a futex) to manage a lock count. However, on other platforms, due to the freelist, there can be memory allocation, which means it might throw std::bad_alloc. Not because of the freelist itself (that uses malloc and will just crash if malloc fails) but because of Q_GLOBAL_STATIC. In 5.1, the global static will be noexcept provided the type's constructor is so too (it is, in this case).
