2. Frontend options

"clang -cc1 is the frontend, clang is the driver." Ref[1]

 

"Some clang command line options are driver-only options, some are frontend-only options.

Frontend-only options are intended to be used only by clang developers.

Users should not run clang -cc1 directly, because -cc1 options are not guaranteed to be stable." Ref[1]

 

"you can run clang -Xclang <option> ... to force the driver pass <option> to clang -cc1." Ref[1]

 

2.1 -###

-###                    Print (but do not run) the commands to run for this compilation

"You can use the -### command-line option to print out the "frontend flags" that have been translated from the driver" Ref[2]
