Coremark-ProをRISC-Vの環境でコンパイルするためにいろいろ修正したまとめ。
まず、util/make/ にRISC-V向けの環境ファイルを追加した。 基本は、fakeio.mak と linux.mak を使ってそれを変更することで対応している。

また、何故かpthreadの定義がコンパイル時に足りないと言われたの、th_al.cに以下を追加した。

最後の方に、余分なdiffが入ってしまっているな... whitespaceを最後に追加してるのを消しちゃったのが原因かな。
これで一通りコンパイルできるようになったが、まだstartupのルーチンとかを入れていないため、ちゃんと動作しないと思う。それはまた修正していく。
ちなみに、x86で動作させるときの実行オプションは、

基本的に引数は付けていないから、main時のargc,argvについて調整を考える必要はないかな。
