In Binutils 2.39 the BFD linker often over-estimate the size of .rela.*. For example if there is only 42 relocations, it may allocate the space for 47 relocations and fill the unused space in the section with zero. Then 5 R_LARCH_NONE will appear. This has already caused trouble when we reviewed LoongArch glibc port, but at last the reviewers considered using NONE relocations as a "padding" acceptable. So in glibc ld.so will treat R_LARCH_NONE as a "dynamic" relocation with no real effect. The issue (or "bug", if we want a more serious term) seems fixed in Binutils trunk, but I've not rebuilt the entire system with it so I'm not sure if it's completely fixed. -- Xi Ruoyao <xry111@xxxxxxxxxxx> School of Aerospace Science and Technology, Xidian University
