This patch fixes the following bugs, all of which were discovered while testing a 32 bit build on a 64 bit machine. * path.itr/iterator.pass.cpp has undefined behavior. 'path::iterator' stashes the value of the element inside the iterator. This violates the BiDirIterator requirements but is allowed for path::iterator. However this means that using reverse_iterator<path::iterator> has undefined behavior because it assumes that 'Iter tmp = it; return *tmp' will not create a dangling reference. However it does, and this caused this particular test to fail. * path.native.obs/string_alloc.pass.cpp tested the SSO with a long string. On 32 bit builds std::wstring only has the SSO for strings of size 2. The test was using a string of size 4. * fs.op.space/space.pass.cpp had overflows while calculating the expected values. The fix here is to convert the statvfs data members to std::uintmax_t before multiplying them. The internal implementation already does this but the tests needed to do it as well. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@273078 91177308-0d34-0410-b5e6-96231b3b80d8
libc++ Documentation ==================== The libc++ documentation is written using the Sphinx documentation generator. It is currently tested with Sphinx 1.1.3. To build the documents into html configure libc++ with the following cmake options: * -DLLVM_ENABLE_SPHINX=ON * -DLIBCXX_INCLUDE_DOCS=ON After configuring libc++ with these options the make rule `docs-libcxx-html` should be available.
