Yes, we should use -fno-plt as the default for cmodel=extreme. x86_64 silently ignores -fplt for cmodel=large (their "large" is like our "extreme"), but perhaps it's better for us to just report an error if someone uses "-mcmodel=extreme -fplt" explicitly (if possible, I'm not sure if we can determine whether -fplt is explicitly given in the backend code). -- Xi Ruoyao <xry...@xry111.site> School of Aerospace Science and Technology, Xidian University
