[PATCH] D146054: [RISCV] Add --print-supported-extensions and -march=help support

[Kito Cheng via Phabricator via cfe-commits]

kito-cheng added inline comments.


================
Comment at: clang/tools/driver/cc1_main.cpp:187-188
+/// Print supported extensions of the given target.
+static int PrintSupportedExtensions(std::string TargetStr) {
+  llvm::riscvMarchHelp();
+
----------------
Plz make sure only RISC-V print that, x86 or other target print RISC-V's ext is really weird.
