* Loosen up the timing requirements on 4 more tests.Howard Hinnant2012-08-044-4/+4

* Andrew Morrow: There are two tests under test/utilities/memory that heap ↵Howard Hinnant2012-08-022-4/+0
| | | | | | | | | | | | | allocate two integers which remain unused and are subsequently leaked, so the test fail when run under valgrind. Unless I'm overlooking a subtle reason why they are needed I think they can be removed, allowing these tests to pass under valgrind. The attached patch removes the variables. If there is a reason for them to exist, I can change this to just delete them at the end of the test. llvm-svn: 161195

* Andrew Morrow: This patch fixesHoward Hinnant2012-08-021-1/+1
| | | | | | | | | test/input.output/iostream.format/output.streams/ostream.formatted/ostream.inserters.arithmetic/pointer.pass.cpp to accept '(nil)' as a valid representation for NULL so that the test passes on Linux. The same thing is already done in some other tests, like in /test/localization/locale.categories/category.numeric/locale.nm.put/facet.num.put.members/put_pointer.pass.cpp. llvm-svn: 161188
* Implement [util.smartptr.shared.atomic]. This is the last unimplementedHoward Hinnant2012-07-3011-0/+409
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | section in libc++. This requires a recompiled dylib. Failure to rebuild the dylib will result in a link-time error if and only if the functions from [util.smartptr.shared.atomic] are used. The implementation is not lock free. After considerable thought, I know of no way to make the implementation lock free. Ideas welcome along that front. But changing the ABI of shared_ptr is not on the table at this point. The mutex used to lock these function is encapsulated by std::__sp_mut. The only thing the client knows about std::__sp_mut is that it has a void* data member, can't be constructed, and has lock and unlock members. Within the binary __sp_mut is currently implemented as a pointer to a std::mutex. That can change in the future without disturbing the ABI (as long as sizeof(__sp_mut) remains constant. I specifically did not make __sp_mut a spin lock as I have a pathological distrust of spin locks. Testing on OS X reveals that the use of std::mutex in this role is not a large performance penalty as long as the contention for the mutex is low (more likely to get the lock than to have to wait). In the future we can still make __sp_mut a spin lock if that is what is desired (without ABI damage). The dylib contains 16 __sp_mut's to be chosen based on the hash of the address of the shared_ptr. The constant 16 is a ball-park reasonable space/time tradeoff. std::hash<T*> was changed to call __murmur2_or_cityhash, instead of the identity function. I had thought we had already done this, but I was mistaken. All of this is under #if __has_feature(cxx_atomic) even though the implementation is not lock free, because the signatures require access to std::memory_order, which is currently available only under __has_feature(cxx_atomic). llvm-svn: 160940

* This commit establishes a new bucket_count policy in the unordered ↵Howard Hinnant2012-07-064-4/+4
| | | | | | containers: The policy now allows a power-of-2 number of buckets to be requested (and that request honored) by the client. And if the number of buckets is set to a power of 2, then the constraint of the hash to the number of buckets uses & instead of %. If the client does not specify a number of buckets, then the policy remains unchanged: a prime number of buckets is selected. The growth policy is that the number of buckets is roughly doubled when needed. While growing, either the prime, or the power-of-2 strategy will be preserved. There is a small run time cost for putting in this switch. For very cheap hash functions, e.g. identity for int, the cost can be as high as 18%. However with more typical use cases, e.g. strings, the cost is in the noise level. I've measured cases with very cheap hash functions (int) that using a power-of-2 number of buckets can make look up about twice as fast. However I've also noted that a power-of-2 number of buckets is more susceptible to accidental catastrophic collisions. Though I've also noted that accidental catastrophic collisions are also possible when using a prime number of buckets (but seems far less likely). In short, this patch adds an extra tuning knob for those clients trying to get the last bit of performance squeezed out of their hash containers. Casual users of the hash containers will not notice the introduction of this tuning knob. Those clients who swear by power-of-2 hash containers can now opt-in to that strategy. Clients who prefer a prime number of buckets can continue as they have. llvm-svn: 159836

* The rules for emplace in map, multimap, unordered_map and unordered_multimap ↵Howard Hinnant2012-05-259-12/+33
| | | | | | changed a while back and I'm just now updating to these new rules. In a nutshell, you've got to know you're emplacing to a pair and use one of pair's constructors. I made one extension: If you want to emplace the key and default construct the mapped_type, you can just emplace(key), as opposed to emplace(piecewise_construct, forward_as_tuple(key), forward_as_tuple()). llvm-svn: 157503

| | | | | | is/will be making convincing arguments that a modified form of LWG 2051 (currently NAD Future) is easily acheivable and desirable. He has demonstrated that a tuple<T...> where all of the T are implicitly convertible from U... should have a tuple constructor that is also implicit, instead of explicit. This would support the use cases in LWG 2051 while not undermining T... with explicit conversions from U.... This check-in is an experimental implementation of Daniel's work. I believe this work to be mature enough to warrant inclusion into libc++. If anyone sees real-world problems that this check in causes, please let me know and I will revert it, and provide the feedback to the LWG. llvm-svn: 153855
