URL: https://github.com/llvm/llvm-project/commit/34b412dc0efe898b18b7afcf02d9e44d7e05b5ec DIFF: https://github.com/llvm/llvm-project/commit/34b412dc0efe898b18b7afcf02d9e44d7e05b5ec.diff LOG: [clang][RISCV][test] Add coverage for __fp16 support in arguments/returns By choice, we don't set HalfArgsAndReturns=true (which would allow __fp16 in args and returns). Add test coverage for this to ensure it isn't changed by accident.
