preprocessed source code
When I execute the commands:
{{{
clang++-mp-3.3 -Wall -g -std=c++11 -stdlib=libc++ -march=native -O4 -o
CMakeFiles/bench.dir/bench.cc.o -c /Users/eschnett/src/cc/vecmathlib/bench.cc
clang++-mp-3.3 -v -Wall -g -std=c++11 -stdlib=libc++ -march=native -O4
-Wl,-search_paths_first -Wl,-headerpad_max_install_names
CMakeFiles/bench.dir/bench.cc.o -o bench
}}}
then I receive this error:
{{{

}}}
Things work fine if I replace -O4 by -O3. My processor does support the
blendvps instruction.</pre>
