This revision now requires changes to proceed.


================
Comment at: clang/test/Driver/print-supported-extensions.c:1
+// Test that --print-supported-extensions lists supported extensions.
+
----------------
Some newer tests use `///` to distinguish non-CHECK-non-RUN comments from 
others. This helps automation tools to catch wrong prefixes (e.g. with a typo) 
in comments and helps auto-generating checks in the future while retaining 
manual comments.


================
Comment at: clang/test/Driver/print-supported-extensions.c:3
+
+// REQUIRES: riscv-registered-target
+
----------------
If you remove `all` and `RISCV` from `LLVM_TARGETS_TO_BUILD`, you can test 
whether this feature works without lib/Target/RISCV support. I suspect it 
works, so you may need another build for verification.


================
Comment at: clang/test/Driver/print-supported-extensions.c:10
+// CHECK-RISCV: Target: riscv64
+// CHECK-NEXT: All available -march extensions for RISC-V
+// CHECK-NEXT:         Name                Version
----------------
The formatting matters here. To test formatting see `--strict-whitespace 
--match-full-lines` (example: See
