7b7e7f1da2 Check symbol defined by assignment in linker script
Symbol symbol defined by an assignment in a linker script has type
bfd_link_hash_new.  elf_i386_convert_load and elf_x86_64_convert_load

script.

a6af384b19 Properly convert address load of __start_XXX/__stop_XXX
Since __start_XXX and __stop_XXX symbols aren't defined when address
load is being converted, we need to check if there is an XXX output
section to get their section and value.  This patch adds a new function,
bfd_link_get_defined_symbol, to search for the XXX output section to
check if __start_XXX and __stop_XXX symbols are defined.

0e1862bb40 Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs.  This
patch adds an "output_type" field:

enum output_type
{
  type_unknown = 0,
  type_executable,
  type_dll,
  type_relocatable
};

and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC.  Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

ce875075f9 PR ld/17973 LTO file syms
LTO output objects have an STT_FILE symbol using the name of the file,
a temporary file.  This results in executables that can't be exactly
reproduced, so the file name needs to be dropped.  We don't want to
lose all file symbols when linking a mix of lto and non-lto objects as
a file symbol can be used to figure which source file generated a
given local symbol.  So lto output objects need to be marked.

I chose to mark lto output objects with a new bfd flag.  This flag is
also used to fix a bug in the link-once handling;  An object being
loaded after "loading_lto_outputs" is set might be one extracted from
an archive to satisfy new references from lto objects, not an lto
object itself.

The new flag is copied from archive to elements, and the same done
for no_export.  This fixes a bug in that --exclude-libs doesn't work
with thin archives.  I'm not completely happy with this part of the
patch and may revist this to avoid the hack in
_bfd_look_for_bfd_in_cache.

6346d5ca43 Fallout from recent bfd_reloc_outofrange changes
Commit ec93045b and cd21f5da introduced a large number of tic4x and
tic54x regressions, due to the new checks being wrong for targets
with octets_per_byte != 1.  To fix that I introduced a new
bfd_get_section_limit_octets and performed the check on octets rather
than byte adresses, reducing the number of bfd_octets_per_byte calls.
bfd_octets_per_byte is rather expensive..

I then wondered why the same bfd_reloc_outofrange check added to
bfd_perform_relocation wasn't also added to bfd_install_relocation.
The two functions are virtually identical and ought to remain that
way.  However, adding the same check to bfd_install_relocation
resulted in ld-elf "FAIL Link eh-group.o to eh-group" on many ELF
targets, including x64_64-linux.  The reason being that eh-group.o
has NONE relocs at the end of a section, and most targets give NONE
relocs a non-zero size.  So if we are to keep the new outofrange
check it appears that NONE relocs must have a zero size.

	(bfd_get_section_limit): ..here.

The main aim of this change was to have non_ir_ref set correctly on

WARN has always been able to be handled by the CWARN case (WARN was

must be on the undefs list, so the CWARN test passes).  So let's merge

13e570f80c Fix LTO vs. COFF archives
Avoid scan of symbols on objects in coff archives since we don't need
to do anything special with common symbols.  The scan is quite useless,
and breaks LTO due to slim LTO objects not having symbols available
until after the plugin has claimed them.  Instead we can add objects
based on their archive symbol map.

Also, rip out the archive symbol hash table used by the generic
linker.  Using a hash breaks one feature of unix archive linking;
The first object file in an archive defining any given symbol should
be the object extracted to satisfy that symbol.  What's more a hash
isn't much faster except in pathological cases where object file
ordering causes many scans of the archive.  See the comment which I'm
removing from elf_link_add_archive_symbols.

Finally, tidy elflink.c archive handling a little.

bffebb6ba5 Copy st_other for linker script symbol assignments
This fixes a problem seen on powerpc64le ELFv2 when creating a
function symbol alias with ld --defsym.  st_other needs to be copied
from the source symbol to the alias in order to set up the local entry
offset for the alias.  I decided to make this change in the generic
ELF code rather than in elf64-ppc.c since it looks like other targets
that use st_other bits might benefit too.
