Adjust LOAD segment to generate GNU_RELRO segment This patch fixes 2 GNU_RELRO segment bugs: 1. lang_size_sections didn't properly align base to the maximum alignment power of sections between DATA_SEGMENT_ALIGN and DATA_SEGMENT_RELRO_END. 2. ld failed to adjust LOAD segment to generate GNU_RELRO segment when LOAD segment doesn't fit GNU_RELRO segment. This is https://sourceware.org/bugzilla/show_bug.cgi?id=14207 We "fixed" ld by not generating GNU_RELRO segment. This patch adjusts LOAD segment to generate GNU_RELRO segment. It fixes PR ld/16322 and at the same time it also fixes PR binutils/16323 since now we can adjust LOAD segment if it is too small. bfd/ PR ld/14207 PR ld/16322 PR binutils/16323 * elf.c (_bfd_elf_map_sections_to_segments): Don't check section size for PT_GNU_RELRO segment.
