* Merging r197718:Bill Wendling2013-12-20
| | | | | | | | | | | | | | | | | | | | ------------------------------------------------------------------------ r197718 | hans | 2013-12-19 12:32:44 -0800 (Thu, 19 Dec 2013) | 10 lines Make sys::ThreadLocal<> zero-initialized on non-thread builds (PR18205) According to the docs, ThreadLocal<>::get() should return NULL if no object has been set. This patch makes that the case also for non-thread builds and adds a very basic unit test to check it. (This was causing PR18205 because PrettyStackTraceHead didn't get zero- initialized and we'd crash trying to read past the end of that list. We didn't notice this so much on Linux since we'd crash after printing all the entries, but on Mac we print into a SmallString, and would crash before printing that.) ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@197778 91177308-0d34-0410-b5e6-96231b3b80d8

* [weak vtables] Remove a bunch of weak vtablesJuergen Ributzka2013-11-19
| | | | | | | | | | | | This patch removes most of the trivial cases of weak vtables by pinning them to a single object file. The memory leaks in this version have been fixed.

* Revert r194865 and r194874.Alexey Samsonov2013-11-18
| | | | | | | | | | | | | This change is incorrect. If you delete virtual destructor of both a base class and a subclass, then the following code: Base *foo = new Child(); delete foo; will not cause the destructor for members of Child class. As a result, I observe plently of memory leaks. Notable examples I investigated are: ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194997 91177308-0d34-0410-b5e6-96231b3b80d8
* [block-freq] Add BlockFrequency::scale that returns a remainder from the ↵Michael Gottesman2013-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | division and make the private scale in BlockFrequency more performant. This change is the first in a series of changes improving LLVM's Block Frequency propogation implementation to not lose probability mass in branchy code when propogating block frequency information from a basic block to its successors. This patch is a simple infrastructure improvement that does not actually modify the block frequency algorithm. The specific changes are: 1. Changes the division algorithm used when scaling block frequencies by branch probabilities to a short division algorithm. This gives us the remainder for free as well as provides a nice speed boost. When I benched the old routine and the new routine on a Sandy Bridge iMac with disabled turbo mode performing 8192 iterations on an array of length 32768, I saw ~600% increase in speed in mean/median performance. 2. Exposes a scale method that returns a remainder. This is important so we can ensure that when we scale a block frequency by some branch probability BP = N/D, the remainder from the division by D can be retrieved and propagated to other children to ensure no probability mass is lost (more to come on this). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194950 91177308-0d34-0410-b5e6-96231b3b80d8

* Expose install_fatal_error_handler() through the C API.Filip Pizlo2013-10-17
| | | | | | | | | | | | | | | | | | | I expose the API with some caveats: - The C++ API involves a traditional void* opaque pointer for the fatal error callback. The C API doesn’t do this. I don’t think that the void* opaque pointer makes any sense since this is a global callback - there will only be one of them. So if you need to pass some data to your callback, just put it in a global variable. - The bindings will ignore the gen_crash_diag boolean. I ignore it because (1) I don’t know what it does, (2) it’s not documented AFAIK, and (3) I couldn’t imagine any use for it. I made the gut call that it probably wasn’t important enough to expose through the C API. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192864 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | Some background: One can pass compiled resource files (.res files) directly to the linker on Windows.

* Windows: Use GetModuleHandleEx instead of LoadLibraryDavid Majnemer2013-10-13
| | | | | | | | | | | | | | | | | | | | We were using an anti-pattern of: - LoadLibrary - GetProcAddress - FreeLibrary This is problematic because of several reasons: - We are holding on to pointers into a library we just unloaded. - Calling LoadLibrary results in an increase in the reference count of the library in question and any libraries that it depends on and so-on and so-forth. This is none too quick. Instead, use GetModuleHandleEx with GET_MODULE_HANDLE_EX_FLAG_PIN. This is done because because we didn't bring the reference for the library into existence and therefor shouldn't count on it being around later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192550 91177308-0d34-0410-b5e6-96231b3b80d8
