--- Comment #7 from JuzheZhong <juzhe.zhong at rivai dot ai> --- Hi, Robin. I sent a patch switching cost model into generic cost model: https://gcc.gnu.org/pipermail/gcc-patches/2024-January/642428.html But I tweak the cost back to default cost. Since current generic cost model has inferior codegen in dynamic-lmul2-7.c, I think we should switch it first, then we can together tune the cost model together so that we don't block our work.
