A 'more' apples to apple comparison would be to do: clang -emit-llvm-bc | opt -std-compile-opts | llc > foo.s at compile time, which roughly corresponds to -O3. It will be slower because of the forking/execing and writing/reading of bc files, but the codegen should be comparable. -Chris _______________________________________________ cfe-dev mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/cfe-dev
