The canonical comment is `/*AddAllExtensions=*/true`


================
Comment at: clang/test/Driver/riscv-cpus.c:86
+// MCPU-ABI-SIFIVE-S21: "-target-feature" "+c"
+// MCPU-ABI-SIFIVE-S21: "-target-feature" "+64bit"
 // MCPU-ABI-SIFIVE-S21: "-target-abi" "lp64"
----------------
If the two features are adjacent, I suggest you place them one the same line.
