For now, if the name of sifive-s21 can't be both RV32 and RV64. It must distinguish the name in RISCVTargetParser.def. ================ Comment at: clang/test/Driver/riscv-arch.c:414 +// RUN: -fsyntax-only 2>&1 | FileCheck -check-prefix=RV64-TARGET %s +// RUN: %clang --target=riscv32-unknown-elf -mabi=lp64 -### %s \ +// RUN: -fsyntax-only 2>&1 | FileCheck -check-prefix=RV64-TARGET %s ---------------- jrtc27 wrote: > IMO this kind of thing should remain an error, you're asking for an ABI that > doesn't exist for the requested architecture IMO, if -march is accepted to override riscv32 target triple, and march can get by `riscv::getRISCVArch` function with -mabi, then it should also accept. Or `riscv::getRISCVArch` should not get -march from -mabi.
