In <https://sourceware.org/ml/binutils/2015-12/msg00190.html> (commit
4a07dc8135), Kwok fixed a problem with
the template used for a dummy BFD for an IR file for LTO on MinGW,
where the input and output formats are not the same.
A problem, however, remains in the case of linking for
x86_64-w64-mingw32 -m32, where LTO linking reports an ambiguity
between the pe-i386 and pei-i386 formats. An object (pe-i386) with
plugin data is being tested by the linker to see what formats match.
The default format initially set by the linker when
bfd_check_format_matches is called is pei-i386 (as that's the output
format from the linker script), which does not match, so the function
goes on to the loop over possible BFD vectors. The pe-i386 vector
matches, as it should. One other vector matches: the plugin vector.
bfd_check_format_matches tests a vector for matching by temporarily
modifying the BFD object to use that vector then using
_bfd_check_format on it. So the BFD object is temporarily using
plugin_vec. _bfd_check_format ends up using bfd_plugin_object_p which
uses plugin_object_p from ld which uses plugin_get_ir_dummy_bfd which
succeeds, having created a BFD based on link_info.output_bfd (because
srctemplate is the BFD temporarily using plugin_vec, even after Kwok's
patch link_info.output_bfd is all that's available to base the dummy
BFD on). So we end up with a match from the plugin vector which uses
the pei-i386 vector even though the pei-i386 vector itself does not
match the input object. (In the i686-mingw32 case, as opposed to this
multilib case, pe-i386 is the default BFD target, which would
short-circuit that logic.)
There are two cases of the linker handling inputs with a plugin: they
may be inputs that are also accepted by some non-plugin BFD format, as
here, or they may be a format that would not be recognized at all, as
with some tests in the ld testsuite. In the former case, there is no
need for BFD to accept the objects using the plugin vector, as the
linker has its own logic to allow plugins to claim objects accepted by
some other BFD vector. Thus, this patch arranges for the plugin
vector to have the lowest match priority, and for the priority from
that vector to be used in the relevant case (the attempted match to
the plugin vector results in TEMP pointing to the pei-i386 vector).
Tested for GCC and Binutils testsuites for x86_64-pc-linux-gnu, as
well as verifying that it fixes the observed LTO issue for
x86_64-w64-mingw32.

As defined at AArch64 ELF Specification (4.6.7 Call and Jump
relocations), symbol with type of non STT_FUNC but in different input
section with relocation place should insert long branch veneer also.
Meanwhile the current long branch veneer infrastructure havn't considered
the situation where the branch destination is "sym_value + rela->addend".
This was OK because we only insert veneer for long call destination is
STT_FUNC symbol for which the addend is always zero. But as we relax the
support to other situations by this patch, we need to handle addend be
non-zero value. For example, for static function, relocation against
"local symbol" are turned into relocation against "section symbol + offset"
where there is a valid addend.

The convention within for relocation names is that they start with the
string "R_", however, this is not so for ARC for the display names of
relocations, however, internally, the names for the relocations types do
have the 'R_' prefix. I suspect that the missing 'R_' on the output
strings was an oversight, as I can't see any comment to the contrary.

We have a problem in that in making compatibility checks while merging
private BFD data on the MIPS target we give priority to the attribute
check, which may fail and cause the function to abort early on. The
problem with this is the ABI compatibility aspect recorded in the
attributes is relatively minor compared to aspects recorded in the ELF
file header. However the premature exit causes any more important
compatibility aspect violated to be masked and not reported to the user
once a problem with attributes has been noticed.
So move the attribute check after the ELF file header flag check in
`_bfd_mips_elf_merge_private_bfd_data', and do not return prematurely
there. Take advantage of the resulting grouping of ELF file header
handling together and remove the premature success return point for the
first input object being handled, letting the code later on figure out
output ABI flags even for this object.
Update LD test cases according to messages from ELF file header checks
now preceding ones from attribute checks.
