If you add "-v --save-temps" to the c++ invocation, it'll show you the separate command lines it executes for the subprograms; the first invocation will be of cc1plus, using the -E flag to generate the preprocessed source into a .ii file, it's the second invocation you want, the one which uses the "-fpreprocessed" flag and names the .ii file as input, which is the one that actually then compiles the pre-processed source into assembly.
