H.J. Lu 3084d7a27b ELF: Add _bfd_elf_add_dynamic_tags
All ELF backends with shared library support need to add dynamic tags.
Add dt_pltgot_required and dt_jmprel_required to elf_link_hash_table to
indicate that DT_PLTGOT and DT_JMPREL are required dynamic tags.

1. Add _bfd_elf_add_dynamic_tags to add common dynamic tags.
2. Add _bfd_elf_maybe_vxworks_add_dynamic_tags to add common VxWorks
dynamic tags.

H.J. Lu c4b126b87a ELF: Don't check relocations in non-loaded, non-alloced sections
Don't do anything special with non-loaded, non-alloced sections.
In particular, any relocs in such sections should not affect GOT
and PLT reference counting (ie. we don't allow them to create GOT
or PLT entries), there's no possibility or desire to optimize TLS
relocs, and there's not much point in propagating relocs to shared
libs that the dynamic linker won't relocate.

Since check_relocs is no longer called on non-loaded, non-alloced
sections, remove SEC_ALLOC check.  Resolve relocation in debug section
against symbol defined in shared library to 0.

Alan Modra 986f078366 bfd_size_type to size_t
bfd_size_type was invented a long time ago in the K&R days.  Many
places in binutils ought to be using size_t instead (and there are
lots of places that use long or unsigned long that really ought to use
size_t too).  Note that you can't change everything over to size_t: A
32-bit host needs a larger type than size_t to support reading and
processing of 64-bit ELF object files.  This patch just tidies some
of the more obvious uses of bfd_size_type that could be size_t.  There
no doubt are more lurking in the source.  Incidentally, practically
all functions used for output of object files can use size_t and don't
need to worry about overflow of size expressions.  If you have
something like
  symcount * sizeof (void *)
when symcount is counting symbols already in memory then you know that
this expression can't overflow since the size of a symbol in memory is
larger by far than that of a pointer.

Alan Modra fd3619828e bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions.  The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections.  Those sections shouldn't be modified
anyway.

The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma.  I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section.  This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

Stafford Horne 09f7b0de53 or1k: Fix incorrect value in PLT GOT entries, causing infinite loop
The PLT GOT entry should point to the first PLT entry which contains the
runtime linker function.  It was pointing back to the symbol PLT entry
causing an infinite loop.

I found this when testing the OpenRISC glibc port which uses the runtime
dynamic linker.  It seems other libc's we use so far have not been
making use of the initial PLT GOT entries.

bfd/ChangeLog:

	* elf32-or1k.c (or1k_elf_finish_dynamic_symbol): Use correct value for
	PLT GOT entries.

Alan Modra 06f44071cc ELF final_write_processing
Move setting of OSABI to final_write_processing, after symbols are
written.  This allows OSABI to be set based on symbols actually
written to the output rather than assuming input symbols will be
output.

Stafford Horne c8e98e3692 or1k: Add the l.adrp insn and supporting relocations
This patch adds the new instruction and relocation as per proposal:
   https://openrisc.io/proposals/ladrp

This is to be added to the spec in an upcoming revision.  The new instruction
l.adrp loads the page offset of the current instruction offset by
a 21-bit immediate shifted left 13-bits.  This is meant to be used with
a 13-bit lower bit page offset.  This allows us to free up the got
register r16.

  l.adrp  r3, foo
  l.ori   r4, r3, po(foo)
  l.lbz   r5, po(foo)(r3)
  l.sb    po(foo)(r3), r6

The relocations we add are:

 - BFD_RELOC_OR1K_PLTA26	For PLT jump relocation with PLT entry
   asm: plta()			implemented using l.ardp, meaning
				no need for r16 (the GOT reg)

 - BFD_RELOC_OR1K_GOT_PG21	Upper 21-bit Page offset got address
   asm: got()
 - BFD_RELOC_OR1K_TLS_GD_PG21	Upper 21-bit Page offset with TLS General
   asm: tlsgd()			Dynamic calculation
 - BFD_RELOC_OR1K_TLS_LDM_PG21	Upper 21-bit Page offset with TLS local
   asm: tlsldm()		dynamic calculation
 - BFD_RELOC_OR1K_TLS_IE_PG21	Upper 21-bit Page offset with TLS Initial
   asm: gottp() 		Executable calculation
 - BFD_RELOC_OR1K_PCREL_PG21	Default relocation for disp21 (l.adrp
				instructions)

 - BFD_RELOC_OR1K_LO13		low 13-bit page offset relocation
   asm: po()			i.e. mem loads, addi etc
 - BFD_RELOC_OR1K_SLO13		low 13-bit page offset relocation
   asm: po()			i.e. mem stores, with split immediate
 - BFD_RELOC_OR1K_GOT_LO13,	low 13-bit page offset with GOT calcs
   asm: gotpo()
 - BFD_RELOC_OR1K_TLS_GD_LO13	Lower 13-bit offset with TLS GD calcs
   asm: tlsgdpo()
 - BFD_RELOC_OR1K_TLS_LDM_LO13	Lower 13-bit offset with TLS LD calcs
   asm: tlsldmpo()
 - BFD_RELOC_OR1K_TLS_IE_LO13	Lower 13-bit offset with TLS IE calcs
   asm: gottppo()

Alan Modra 3bf083ed23 dyn_relocs tidy
Many targets define their own dyn_relocs struct when they could use
struct elf_dyn_relocs.  This patch tidies that, and uses
readonly_dynrelocs in a few more places.

The SH adjust_dynamic_symbol had some really weird code dating back to
2002 that looked over dynamic relocations for any in SEC_HAS_CONTENTS
or SEC_READONLY sections, rather than just the usual SEC_READONLY
sections.  So basically any dynamic relocation.  What's more, the SH
relocate_section has no support for emitting dynamic relocations in
non-PIC.  In other words, SH has no support for avoiding copy relocs
in non-PIC.  I've made that more obvious by using "if (0 && ..)" in
asjust_dynamic_symbol.

Unfortunately, LM32, M32R, NDS32, and OR1K copied the bogus SH
adjust_dynamic_symbol code.  So none of those targets would have
avoided copy relocs.  LM32, M32R, NDS32 get the "if (0)" treatment
too.  (LM32 is even more broken in that non_got_ref is never set.)

OR1K relocate_section looks like it might support dynamic relocs in
non-PIC, so I've enabled the copy reloc avoidance code for that
target.

Alan Modra 63c1f59d66 readonly_dynrelocs
In early October, HJ Lu added support for a number of targets to "Dump
dynamic relocation in read-only section with minfo".  This extends
that support to more targets, displays the symbol involved, and splits
the existing function that sets TEXTREL into a "readonly_dynrelocs"
and "maybe_set_textrel" function.  I'll need "readonly_dynrelocs" if I
ever get around to fixing "pr22374 function pointer initialization"
fails.

am33_2.0, arc, bfin, hppa64, mn10300, and nios2 fail to mark a binary
needing text relocations with DT_TEXTREL.  That's not good.  xtensa also
fails to do so but complains about "dangerous relocation: dynamic
relocation in read-only section" so I reckon that is fine and have
marked the test as an xfail.  The other targets need maintainer
attention.

Curiously, the map file dump wasn't added for x86, so the map test

Alan Modra 60d67dc84b Rename u.weakdef and make it a circular list
This makes the elf_link_hash_entry weakdef field, currently used to
point from a weak symbol to a strong alias, a circular list so that
all aliases can be found from any of them.  A new flag, is_weakalias,
distinguishes the weak symbol from a strong alias, and is used in all
places where we currently test u.weakdef != NULL.

With the original u.weakdef handling it was possible to have two or
more weak symbols pointing via u.weakdef to a strong definition.
Obviously that situation can't map to a circular list; One or more of
the weak symbols must point at another weak alias rather than the
strong definition.  To handle that, I've added an accessor function to
return the strong definition.

H.J. Lu 5c3261b0e8 ELF: Call check_relocs after opening all inputs
For all ELF targers, call check_relocs after opening all inputs and
garbage collection.  Since the symbol resolution is known, check_relocs
can be simplified.  Also garbage collection doesn't need to undo what
check_relocs has done for symbols which have been garbage collected.
Since ELF targets never see the removed sections, gc_sweep_hook can be
removed from elf_backend_data and we can avoid GOT/PLT with garbage
collection now.

Set link_info.check_relocs_after_open_input to TRUE for all linker
targets which use ELF linker and update garbage collection tests to
remove unused GOT section.

ldemul_after_check_relocs is added for powerpc to support --secure-plt,
--bss-plt and --sdata-got.

Tested natively without regressions on i686, x86-64 and x32.  Tested

Alan Modra afbf7e8e3a Don't make dynamic .data.rel.ro SEC_READONLY
I'd made this dynamic section read-only so a flag test distinguished
it from .dynbss, but like any other .data.rel.ro section it really
should be marked read-write.  (It is read-only after relocation, not
before.)  When using the standard linker scripts this usually doesn't
matter since the output section is among other read-write sections and
not page aligned.  However, it might matter in the extraordinary case
of the dynamic section being the only .data.rel.ro section with the
output section just happening to be page aligned and a multiple of a
page in size.  In that case the output section would be read-only, and
live it its own read-only PT_LOAD segment, which is incorrect.

Alan Modra 5474d94f03 dynrelro section for read-only dynamic symbols copied into executable
Variables defined in shared libraries are copied into an executable's
.bss section when code in the executable is non-PIC and thus would
require dynamic text relocations to access the variable directly in
the shared library.  Recent x86 toolchains also copy variables into
the executable to gain a small speed improvement.

The problem is that if the variable was originally read-only, the copy
in .bss is writable, potentially opening a security hole.  This patch
cures that problem by putting the copy in a section that becomes
read-only after ld.so relocation, provided -z relro is in force.

The patch also fixes a microblaze linker segfault on attempting to
use dynamic bss variables.

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".

Alan Modra 4ade44b727 Set dynamic tag VMA and size from dynamic section when possible
Rather than searching the output for a specific named section, it's

section name, making it possibile to map dynamic sections differently.

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.
