Hello, It looks like compiler-rt CMake scripts don't take CMAKE_CXX_FLAGS into account. This is because clang_compile and clang_link_shared functions call the newly-built compiler directly, and they don't add those flags. Using CMAKE_CXX_FLAGS is necessary on systems where the C++11-enabled libstdc++ is installed not in the default location. For example, the CentOS buildbot uses: -DCMAKE_CXX_FLAGS=--gcc-to...

...us to be very specific about command-line flags. Of course "just-built Clang" will still need to use system headers and (for unit tests) even system libraries, so _some_ flags must remain configurable by the user. But I'd rather work on the bright future than fix the existing and ugly clang_compile, clang_link etc. set of rules :) Let me know if you're OK with this, or you are in desperate need of the short-term fix (it prevents you from setting up a buildbot, or smth. like that). > > 1) Different compilers.
