`-mllvm` 后端选项，不走前端语法糖。`--cce-simd-vf-fusion=false` 实际展开成这 7 个后端 pass 选项（false 分支，按编译器源码）： + +``` +-mllvm -cce-vf-enable-vf-fusion=false +-mllvm -cce-vf-enable-vf-loop-extender=false +-mllvm

vf-fusion 选项跑 sim + +ptoas 调 bisheng 的 argv 由 `tools/ptoas/ObjectEmission.cpp` 构造，无原生透传机制。要让 sim 也跑 vf-fusion off，可在该文件的 vec-misched 注入之后加 env 读取，把 `PTOAS_BISHENG_VF_ARGS`（空格分隔）的 token 追加进 bisheng argv，然后 rebuild。跑 sim 时： + +```bash +export PTOAS_BISHENG_VF_ARGS="-mllvm -cce-vf-enable-vf-fusion=false -mllvm -cce-vf-enable-vf-loop-extender=false -mllvm -cce-vf-enable-loop-fusion=false -mllvm
