--- Comment #7 from Jiangning Liu <jiangning.liu at amperecomputing dot com> --- Without reverting the commit g:1118a3ff9d3ad6a64bba25dc01e7703325e23d92, we still see exchange2 performance issue for aarch64. BTW, we have been using -fno-inline-functions-called-once to get the best performance number for exchange2.
