[PATCH] D145883: [Flang][RISCV] Emit target features for RISC-V

[Andrzej Warzynski via Phabricator via cfe-commits]

awarzynski added a comment.

Why does "flang/test/Driver/target-features.f90" list all RISC-V features?  Why not use https://github.com/llvm/llvm-project/blob/main/flang/test/Driver/target-cpu-features.f90 instead?

+! RUN: %flang --target=riscv64-linux-gnu --target=riscv64 -c %s -### 2>&1 \
+! RUN: | FileCheck %s -check-prefix=CHECK-RV64
----------------
What happens if the RISC-V backend is not available?

 This one line will require updating once respective bit of LLVM is updated. Let's avoid that :)
