SPEC2017をビルド・実行できる環境を作ろう (7. RISC-V 向けバイナリでQEMUの実行環境を構築する)

RISC-V バイナリを QEMU で動作させる試行の続き。

LLVMコンフィグレーションでRISC-Vバイナリとしてコンパイルして、QEMUで動かそう。 チマチマ実行コマンドを追加していく。

x264の実行については1つ注意が必要だ。BuckBunny.yuv を先に生成する必要がある。

cd /home/msyksphinz/work/spec2017/spec2017_llvm_riscv64/benchspec/CPU/625.x264_s/run/run_base_test_mytest-m64.0000 && \
qemu-riscv64 -L /home/msyksphinz/work/spec2017/riscv-rootfs /home/msyksphinz/work/spec2017/spec2017_llvm_riscv64/benchspec/CPU/625.x264_s/exe/ldecod_s_base.mytest-m64 -i BuckBunny.264 -o BuckBunny.yuv \
> /home/msyksphinz/work/spec2017/log/inputgen_ldecod_s_base.mytest-m64_x264.out 2>&1

そのあとで、QEMU上でひたすら実行していくわけだ。
