Fallout from "Reorder more powerpc64 sections for -z relro"
Commit 23283c1b changed the layout of some bss style sections on powerpc64, but neglected to add a page gap before the third PT_LOAD segment created by this reording. Without a page gap we get two PT_LOAD headers that overlap by one page in memory. That shouldn't be allowed because the dynamic loader will load garbage from the first page of the last segment over the last page of the previous segment. bfd/ * elf.c (_bfd_elf_map_sections_to_segments): Do not make a new segment for loaded sections after nonloaded sections if the sections are on the same page. ld/testsuite/ * ld-powerpc/elfv2so.d: Update
