--- Comment #23 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Comment on attachment 45830 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=45830 proposed patch Please update the get_block_for_section function comment accordingly: /* Return the object_block structure for section SECT. Create a new structure if we haven't created one already. Return null if SECT itself is null. */ This should say that we return NULL also for mergeable sections and why - that section anchors can't be used in mergeable sections anyway, because the linker might move objects around, and that using the object blocks infrastructure in that case is both a waste and maintenance burden. Given: /* Don't use anchors for small data sections. The small data register acts as an anchor for such sections. */ if (sect->common.flags & SECTION_SMALL) return false; we could do the same for SECTION_SMALL, but I'm not suggesting that ATM.
