Summary: -mno-speculative-load-hardening isn't a cc1 option, therefore, before this change: clang -mno-speculative-load-hardening hello.cpp would have the following error: error: unknown argument: '-mno-speculative-load-hardening' This change will only ever forward -mspeculative-load-hardening which is a CC1 option based on which flag was passed to clang. Also added a test that uses this option that fails if an error like the above is ever thrown. Thank you ericwf for help debugging and fixing this error.
