--- Comment #3 from Nick Clifton <nickc at redhat dot com> --- Hi Jiong, Thanks for taking a look at this. > Looks like AArch64 could avoid emiting COPY relocation if it's a relocation > against writable section. We could adopt similar code from > elf_x86_64_adjust_dynamic_symbol or ppc64_elf_adjust_dynamic_symbol. Ah - maybe not. The original testcase (in the BZ) shows the bug happening when constant data is used rather than writeable data. You can also extend the second testcase I posted to use constant data and the same problem happens. >> It looks like the linker creates a copy of IEEEsingle in the executable but >> then the GOT entry for IEEEsingle is not updated in libLLVM.so, causing any >> accesses to IEEEsingle in libLLVM.so to refer to the original definition > > Does this means this is a glibc bug as well? dynamic linker needs to > redirect > the reference in the .so to the copy as well? This is a possibility, although I am not an expert on the dynamic linker. I think however that we need to verify that the static linker is producing the correct dynamic relocations first.
