Constrain bind operator()() to not exist if the call is not valid.  Fixes http://llvm.org/bugs/show_bug.cgi?id=15295.

llvm-svn: 175774

Fix a bug in mutex_try_to_lock.  This was previously trying to unlock a mutex that it didn't own, causing an assertion failure in mutex.cpp.  The issue was that the unique_lock went out of scope, releasing the lock on m, then m.unlock() was called on an already-unlocked mutex.  

This change removes the spurious m.unlock() call.  

If this test was previously passing for anyone with assertions enabled, then they should investigate bugs in their pthread implementation, as pthread_unlock() should not return 0 if the mutex is currently unlocked.

 - This is useful for testing with custom ABI libraries.

 - Patch by Michael van der Westhuizen:
--
r174404 accidentally removed stdc format, limit and constant macros from the Linux test runner logic.  This small patch re-adds the macros.

Making this change fixes the following tests on Linux:
 - depr/depr.c.headers/inttypes_h.pass.cpp
 - depr/depr.c.headers/stdint_h.pass.cpp
 - input.output/file.streams/c.files/cinttypes.pass.cpp
 - language.support/cstdint/cstdint.syn/cstdint.pass.cpp

 - Basically I just ran the thread tests many many times on a busy machine and
   bumped the timeouts whenever I hit a test failure.

 - This is obviously subpar, but is the best I can do without the tests being
   rewritten to not depend on arbitrary timeouts.

Change the 'result_type' from unsigned to 'uint_fast32_t'. This eliminates truncation warnings on Linux

Michael van der Westhuizen: The attached patch add support for building against libc++abi and libcxxrt to CMake builds of libc++.

Usage (with the appropriate CC and CXX environment variables) is:
$ cmake -DLIBCXX_CXX_ABI=libcxxabi '-DLIBCXX_LIBCXXABI_INCLUDE_PATHS=/home/michael/libcxxabi/include' ../libcxx
and:
$ cmake -DLIBCXX_CXX_ABI=libcxxrt '-DLIBCXX_LIBCXXRT_INCLUDE_PATHS=/home/michael/libcxxrt/src' ../libcxx

 - This updates the build script to match the change originally in r149634, so
   that we re-export symbols from libc++abi appropriately.

Marcin Zalewski:  Change the name of a template parameter in __copy_backward from _InputIterator to _BidirectionalIterator to better document the intent of the algorithm.

Give a lot more timing latitude to some of the timing tests. Busy buildbots are hitting the timing limits too often.

llvm-svn: 174539

 - This is a reasonable default, and makes testing just work with no required
   parameters.

 - Add notes on all of the inferred or default values.

 - As of this commit, the test suite should now fully pass on both darwin11 and
   darwin12 when testing against either a locally built libc++ or the system libc++.

llvm-svn: 174478

 - Otherwise, we never were actually linking against the right library when
   building the test applications.

  - This is so that we can easily write XFAIL markers for tests that are known
    to fail with versions of libc++ as were shipped with a particular triple.

llvm-svn: 174443

 - We parse up to the first non-empty non-comment (C++ style) line, otherwise
   the format and semantics match what is used for LLVM/Clang tests.

 - For now, the only interesting thing to test against is a user supplied
   target_triple test parameter.

 - This controls whether to execute against the locally built library or
   not. The default is currently True which maps to what was already being done
   by default.

 - I'd appreciate it if someone can implement the proper handling of this flag
   on linux, I no longer remember the details of its .so handling.

template typename deductions on swap<> (used in string.cpp).  Use
decltype(errno) to replicate the type and qualifier information for holding the
errno value.  Because errno is expected to be assignable, there is no need to
use typename std::remove_const<decltype(errno)>::type to hold the value.

building against libsupc++ as the functions for which they are used are provided
by libsupc++.  Simply preprocess them away when building against libsupc++.
