Alan Modra e81830c5c6 link_hash_copy_indirect and symbol flags 
A while ago HJ fixed PR ld/18720 with commit 6e33951ed, which, among
other things, modified _bfd_elf_link_hash_copy_indirect to not copy
ref_dynamic, ref_regular, ref_regular_nonweak, non_got_ref, needs_plt
and pointer_equality_needed when setting up an indirect non-versioned
symbol pointing to a non-default versioned symbol.  I didn't notice at
the time, but the pr18720 testcase fails on hppa-linux with
"internal error, aborting at binutils-gdb-2.28/bfd/elf32-hppa.c:3933
in elf32_hppa_relocate_section".

Now hppa-linux creates entries in the plt even for local functions, if
they are referenced using plabel (function pointer) relocations.   So
needs_plt is set for foo when processing pr18720a.o.  When the aliases
in pr28720b.o are processed, we get an indirection from foo to
foo@FOO, but don't copy needs_plt.  Since foo@FOO is the "real" symbol
that is used after that point, no plt entry is made for foo and we
bomb when relocating the plabel.

As shown by the hppa-linux scenario, needs_plt should be copied even
for non-default versioned symbols.  I believe all of the others ought
to be copied too, with the exception of ref_dynamic.  Not copying
ref_dynamic is right because if a shared lib references "foo" it
should not be satisfied by any non-default version "foo@FOO".

	* elflink.c (_bfd_elf_link_hash_copy_indirect): Only omit
	copying one flag, ref_dynamic, when versioned_hidden.

Alan Modra 64f52338e9 elf_backend_dtrel_excludes_plt 
Now that all targets creating .rel.plt/.rela.plt use the ELF hash

Alan Modra ce558b89b1 Delete duplicate target short-cuts to dynamic sections 
We'd like to have the elf_link_hash_table srelplt field rather than
some private target field used to save short-cuts to a PLT relocation
section.  This save a little space but mainly is so that the generic
ELF code can access the field.  Ditto for other dynamic sections.

Alan Modra 50e03d47b7 Pass link_info to _bfd_merge_private_bfd_data 
Most BFD linker functions take a bfd_link_info param, which reinforces
the fact that they are linker functions and allow access to linker
callbacks, eg. einfo for printing errors.  I was going to use einfo
for --fatal-warnings support before I decided a better way was the
patch commit 4519d071.

Alan Modra 1a72702bb3 Return void from linker callbacks 
The ldmain.c implementation of these linker callback functions always
return true, so any code handling a false return is dead.  What's
more, some of the bfd backends abort if ever a false return is seen,
and there seems to be some confusion in gdb's compile-object-load.c.
The return value was never meant to be "oh yes, a multiple_definition
error occurred", but rather "out of memory or other catastrophic
failure".

This patch removes the status return on the callbacks that always
return true.  I kept the return status for "notice" because that one
does happen to need to return "out of memory".

H.J. Lu 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.

Alan Modra 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.

Alan Modra 6cabe1ea46 Copy relocations against protected symbols 
Copy relocs are used in a scheme to avoid dynamic text relocations in
non-PIC executables that refer to variables defined in shared
libraries.  The idea is to have the linker define any such variable in
the executable, with a copy reloc copying the initial value, then have
both the executable and shared library refer to the executable copy.
If the shared library defines the variable as protected then we have
two copies of the variable being used.
