* Remove 'const' from MemoryBuffers used through the SourceManagerDavid Blaikie2014-06-27
| | | | | | | | | | | | | | This removes a const_cast added in r211884 that occurred due to an inconsistency in how MemoryBuffers are handled between some parts of clang and LLVM. MemoryBuffers are immutable and the general convention in the LLVM project is to omit const from immutable types as it's simply redundant/verbose (see llvm::Type, for example). While this change doesn't remove "const" from /every/ MemoryBuffer, it at least makes this chain of ownership/usage consistent. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211915 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix a bug in my previous patch by restoring the behavior that the fatalChandler Carruth2014-06-27
| | | | | | | | | | | | | | error handler is only registered once. To avoid the use of std::call_once (the obvious way to do this) I've wrapped everything up into a managed static and done the work in a constructor. Silly, but it should be effective. Some out-of-tree libclang users reported this to me, and I've asked them to put together a test case which exhibits this behavior, but I wanted to fix things ASAP since the nature of the fix is straight forward. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211905 91177308-0d34-0410-b5e6-96231b3b80d8

* Flush C stdio streams upon process terminationReid Kleckner2014-06-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to what can only be described as a CRT bug, stdout and amazingly even stderr are not always flushed upon process termination, especially when the system is under high threading pressure. I have found two repros for this: 1) In lib\Support\Threading.cpp, change sys::Mutex to an std::recursive_mutex and run check-clang. Usually between 30 and 40 tests will fail. 2) Add OutputDebugStrings in code that runs during static initialization and static shutdown. This will sometimes generate similar failures. After a substantial amount of troubleshooting and debugging, I found that I could reproduce this from the command line without running check-clang. Simply make the mutex change described in #1, then manually run the following command many times by running it once, then pressing Up -> Enter very quickly: D:\src\llvm\build\vs2013\Debug\bin\c-index-test.EXE -cursor-at=D:\src\llvm\tools\clang\test\Index\targeted-preamble.h:2:15 D:\src\llvm\tools\clang\test\Index\targeted-cursor.c -include D:\src\llvm\build\vs2013\tools\clang\test\Index\Output\targeted-cursor.c.tmp.h -Xclang -error-on-deserialized-decl=NestedVar1 -Xclang -error-on-deserialized-decl=TopVar | D:\src\llvm\build\vs2013\Debug\bin\FileCheck.EXE D:\src\llvm\tools\clang\test\Index\targeted-cursor.c -check-prefix=PREAMBLE-CURSOR1 Sporadically they will fail, and attaching a debugger to a failed instance indicates that stdin of FileCheck.exe is empty. Note that due to the repro in #2, we can rule out a bug in the STL's mutex implementation, and instead conclude that this is a real flake in the windows test harness. Test Plan: Without patch: Ran check-clang 10 times and saw over 30 Unexpected failures on every run. With patch: Ran check-clang 10 times and saw 0 unexpected failures across all runs.
