John David Anglin <danglin at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jason at gcc dot gnu.org --- Comment #3 from John David Anglin <danglin at gcc dot gnu.org> --- The ELF specification says "To facilitate removing a group without leaving dangling references and with only minimal processing of the symbol table, the following rules are followed. References to the sections comprising a group from sections outside of the group must be made through symbol table entries with STB_GLOBAL or STB_WEAK binding and section index SHN_UNDEF." The label _ZN3uhd9transport3sphL19handle_overflow_nopEv is not globalized. Probably, TREE_PUBLIC is not being set or there needs to be an addition check added to assemble_start_function to globalize COMDAT functions. Jason, could you take a look?
