A downside to the 2017-10-04 PR22245 fix is that bfd_set_error can now silently accept invalid errors if/when someone passes the a value of the wrong enumeration type, which previously would be caught by the -Wenum-conversion warning.

2017-10-05PR21167, relocation sections not included in groupsAlan Modra2-18/+39
This fixes a wart I've known about for years, but haven't done anything about because BFD treats relocation sections as an adjunct to the section they relocate. SHF_GROUP on the section thus implicitly applies to its relocation section(s), but it is an error that the reloc sections aren't part of the group. Like many patches to gas, this wasn't as straightforward as it could be due to a number of backends, i386, cr16 and others, removing relocs in tc_get_reloc rather than marking them as "done" earlier in md_apply_reloc. So it isn't possible for the group support to reliably detect the presence of relocs by looking at fixups earlier than write_relocs. However the group support needs to create signature symbols, and that must be done before the symbol table is frozen, before write_relocs. So split off the group sizing from elf_adjust_symtab and put it in elf_frob_file_after_relocs. bfd/ PR 21167 * elf.c (_bfd_elf_setup_sections): Don't trim reloc sections from groups. (_bfd_elf_init_reloc_shdr): Pass sec_hdr, use it to copy SHF_GROUP flag from section. (elf_fake_sections): Adjust calls. Exit immediately on failure.

Like the PR22230 fix, we can allocate a buffer with an extra byte rather than letting bfd_simple_get_relocated_section_contents malloc and return a buffer.

2017-09-29Fail when string merge can't alloc memoryAlan Modra2-7/+15
I was looking at Debian bug #874674 again today, and think I might have spotted the problem. It appears that merge.c tries to cope with memory allocation failures in some circumstances, but doesn't quite manage to get everything right. This patch will make ld report memory allocation failures instead of silently not merging strings. * merge.c (merge_strings): Return FALSE on malloc failure.
