khchen added a comment. RISCV supports `-mcpu` with default empty arch to align gcc's `-mtune` behavior since clang didn't support `-mtune` before. But now clang has `-mtune`, is it a good idea to remove those options? (ex. `rocket-rv32/rv64`, `sifive-7-rv32/64`)
================ Comment at: clang/test/Driver/riscv-cpus.c:82 +// Check interaction between mcpu and mtune. +// +// RUN: %clang -target riscv32 -### -c %s 2>&1 -mcpu=sifive-e31 -mtune=sifive-e76 | FileCheck -check-prefix=MTUNE-E31-MCPU-E76 %s ---------------- maybe we can describe what is expected interaction behavior somewhere.
