* [libcxx] Add logic to probe compiler in tests.Eric Fiselier2014-12-061-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch probes the cxx compiler used during testing by getting it to dump its predefined macros. Based on the value of these macros the compiler name and compiler name + version are added to the available features. There are three compiler names: - `clang` - `apple-clang` - `gcc`. The available features added are equivalent to: - `'%s' % compiler_name` - `'%s-%s.%s' % compiler_name, major_version, minor_version` This information can be used to XFAIL tests on different compilers / versions.

* Add support for building and testing libc++ without threads to CMake.Eric Fiselier2014-12-064-11/+48
| | | | | | | | | | | Currently hacks must be used in to configure and build libc++ without threads when using CMake. This patch adds CMake options to enable/disable building with threads and a monotonic clock. This patch also propagates the configuration information to lit so the tests are properly configured as well. llvm-svn: 223591

| | | | | | | | | | | | | | DenseSet. DenseSet used to be implemented as DenseMap<Key, char>, which usually doubled the memory footprint of the map. Now we use a compressed set so the second element uses no memory at all. This required some surgery on DenseMap as all accesses to the bucket now have to go through methods; this should have no impact on the behavior of DenseMap though. The new default bucket type for DenseMap is a slightly extended std::pair as we expose it through DenseMap's iterator and don't want to break any existing users. llvm-svn: 223588

I also worked with the idea of exploiting unreachable defaults by omitting the range check for jump tables, but always ended up with a non-neglible binary size increase. It might be worth looking into some more. SimplifyCFG currently does this transformation, but I'm working towards changing that so we can optimize harder based on unreachable defaults.
