All I did was try to self-host Clang.
Maybe I should give some specifics:
- OS: Mac OS X 10.6.8
- Stage 1 compiler: Clang
- Stage 1 options: --enable-optimized --disable-assertions --enable-libcpp CXXFLAGS='-std=gnu++11'
- Stage 2 compiler: Clang (Stage 1)
- Stage 2 options: --enable-optimized --disable-assertions --enable-libcpp --disable-timestamps CXXFLAGS='-std=gnu++11'
It usually hangs (though not always) when trying to build ClangAttrEmitter.cpp during stage 2. Whenever I profile the hanged Clang process, it's always hung in Reassociate.
