libcxx fork for Darling build
30b48cb1b3
I've put some work into the Google Benchmark library in order to make it easier to benchmark libc++. These changes have already been upstreamed into Google Benchmark and this patch applies the changes to the in-tree version. The main improvement in the addition of a 'compare_bench.py' script which makes it very easy to compare benchmarks. For example to compare the native STL to libc++ you would run: `$ compare_bench.py ./util_smartptr.native.out ./util_smartptr.libcxx.out` And the output would look like: RUNNING: ./util_smartptr.native.out Benchmark Time CPU Iterations ---------------------------------------------------------------- BM_SharedPtrCreateDestroy 62 ns 62 ns 10937500 BM_SharedPtrIncDecRef 31 ns 31 ns 23972603 BM_WeakPtrIncDecRef 28 ns 28 ns 23648649 RUNNING: ./util_smartptr.libcxx.out Benchmark Time CPU Iterations ---------------------------------------------------------------- BM_SharedPtrCreateDestroy 46 ns 46 ns 14957265 BM_SharedPtrIncDecRef 31 ns 31 ns 22435897 BM_WeakPtrIncDecRef 34 ns 34 ns 21084337 Comparing ./util_smartptr.native.out to ./util_smartptr.libcxx.out Benchmark Time CPU ----------------------------------------------------- BM_SharedPtrCreateDestroy -0.26 -0.26 BM_SharedPtrIncDecRef +0.00 +0.00 BM_WeakPtrIncDecRef +0.21 +0.21 git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@278147 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.
