This patch enables the `cxx-benchmarks` target by default. Note that the target still has to be manually invoked since it isn't included in the default 'make' rule. This patch also gets the benchmarks building w/ GCC. The build previously required the '-stdlib=libc++' flag but upstream patches to Google Benchmark now allow the library to build w/ libc++ and GCC. These changes should make the benchmarks easier to build and test. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@279999 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.
