+// RUN:   -mabi=lp64f -### 2>&1 | FileCheck %s --check-prefix=RISCV
+// RUN: %clang -target riscv64-unknown-elf %s -fuse-ld=lld -flto \
+// RUN:   -mabi=lp64f -### 2>&1 | FileCheck %s --check-prefix=RISCV
+// RUN: %clang -target riscv64-unknown-linux-gnu %s -fuse-ld=gold -flto \

----------------
This isn't a great test, anything that unconditionally passes `-plugin-opt=target-abi=lp64f` passes it. Test RV32 vs RV64 and with multiple ABIs for each to have confidence it does the right thing. Also have a test for not passing anything.
