dwz in DWARF5 mode might produce DW_UT_partial unit types, which are the same as DW_UT_compile unit types (but start with a DW_TAG_partial_unit) and it might produce DW_FORM_ref_addr to create a reference between units.

2020-06-26libctf, binutils: support CTF archives like objdumpNick Alcock2-34/+86
objdump and readelf have one major CTF-related behavioural difference: objdump can read .ctf sections that contain CTF archives and extract and dump their members, while readelf cannot. Since the linker often emits CTF archives, this means that readelf intermittently and (from the user's perspective) randomly fails to read CTF in files that ld emits, with a confusing error message wrongly claiming that the CTF content is corrupt. This is purely because the archive-opening code in libctf was needlessly tangled up with the BFD code, so readelf couldn't use it. Here, we disentangle it, moving ctf_new_archive_internal from ctf-open-bfd.c into ctf-archive.c and merging it with the helper function in ctf-archive.c it was already using. We add a new public API function ctf_arc_bufopen, that looks very like ctf_bufopen but returns an archive given suitable section data rather than a ctf_file_t: the archive is a ctf_archive_t, so it can be called on raw CTF dictionaries (with no archive present) and will return a single-member synthetic "archive". There is a tiny lifetime tweak here: before now, the archive code could assume that the symbol section in the ctf_archive_internal wrapper structure was always owned by BFD if it was present and should always be freed: now, the caller can pass one in via ctf_arc_bufopen, wihch has the usual lifetime rules for such sections (caller frees): so we add an extra field to track whether this is an internal call from ctf-open-bfd, in which case we still free the symbol section. include/ * ctf-api.h (ctf_arc_bufopen): New. libctf/ * ctf-impl.h (ctf_new_archive_internal): Declare.

2020-06-26binutils, ld: work with --disable-libctfNick Alcock10-7/+117
This unfortunately means conditionalizing out all the libctf code, but the result is not too unbearably ugly, if a bit repetitive. I have stubbed out code in the !ENABLE_LIBCTF path to avoid extra redundant ifdefs where it seems that might be helpful. (The stubs are not too disruptive, but I've tried to keep them on one line where possible to avoid filling up the screen with stubs that nobody would care about. If this is too much of a coding style violation I can change it.)

2020-06-26x86: fix processing of -M disassembler optionJan Beulich2-4/+10
Multiple -M options can be specified in any order. Therefore stright assignment to fields affected needs to be avoided, such that earlier options' effects won't be discarded. This was in particular a problem for -Msuffix followed by certain of the other sub-options. While updating documentation, take the liberty and also drop the redundant mentioning of being able to comma-separate multiple options.
