* clang -fno-caret-diagnostics suppresses warning source lines, carets, and the stats line of "n warnings generated" * clang-tidy -extra-arg-before=-fno-caret-diagnotics only suppresses the "n warnings generated" line. * Pass this flag and -quiet to clang-tidy when WITH_TIDY is not 1 or true. Bug: 69051430 Test: normal build and build with WITH_TIDY=1 Change-Id: I34e34cddc0e7329e73b5f04da4b1458dabfcd4c8
