...are parsed and used by the backend passes: 1. Tools such as clang and llc call cl::ParseCommandLineOptions. Any of the options that should be written to the bitcode as function or module attributes (these options are declared as CodeGenOpt, which is a subclass of cl::opt) are saved to Function or ModuleIntAttrs in CodeGenOptions.cpp. 2. setFunctionAttribute is called to move the function and module options saved in step 1 to the bitcode. Also, options stored in TargetOptions are moved to the bitcode too. Pre-existing attributes in the bitcode are overwritten by the options in the command line. 3. The bac...
