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.

190eb1ddba ELF: Move dyn_relocs to struct elf_link_hash_entry 
All ELF backends with shared library support have

6b728d3286 FIXME for merging of e_flags and .gnu.attributes 
Code in the linker, present before the addition of .gnu.attributes
support, results in shared libraries not being considered by BFD when
merging e_flags and .gnu.attributes from input files to the output.
That doesn't seem correct to me, but I don't know enough about all the
various ABIs to change the behaviour with any confidence.  So this
patch merely punts on dynamic objects in merge_private_bfd_data target
functions, with a FIXME for maintainer attention.

I haven't excluded shared libraries from being considered where the
target merge_private_bfd_data (a) already has code dealing with shared
libraries, or (b) where that function just sets the output to the most
constraining arch/mach combination and other fairly trivial merges, or
(c) when the target has no shared library linker support.

In (a) are: arc, arm, aarch64, riscv, sparc.
In (b) are: bpf, cris, csky, m32r, m68k, mn10300, nios2, tilegx,
	    tilepro, vax, visium, xtensa.
In (c) are: bpf, cr16, h8300, iq2000, m32c, m68hc11, m68hc12, mcore,
	    mep, msp430, mt, rl78, rx, v850.

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.

bb2942085c Pass section when available to bfd_octets_per_byte 
and other tidies.  I think it's better to default to passing the
section to bfd_octets_per_byte, even in cases where we know it won't
make a difference.

A number of the coff reloc functions used bfd_octets_per_byte wrongly,
not factoring it into the offset into the data buffer.  As it happens,
the targets using those files always had bfd_octets_per_byte equal to
one, so there wasn't any detectable wrong behaviour.  However, it is
wrong in the source and might cause trouble for anyone creating a new
target.  Besides fixing that, the patch also defines OCTETS_PER_BYTE
as one in target files where that is appropriate.

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.

7af5d5c4dd PR23980, assertion fail 
All of the backend relocate_section functions that interpret reloc
numbers assuming the input file is of the expected type (ie. same as
output or very similar) really ought to be checking input file type.
Not many do, and those that do currently just assert.  This patch
replaces the assertion with a more graceful exit.

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.

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
currently fail on x86.  It also fails on alpha, am33_2.0, arc, bfin,
hppa64, ia64, m68k, mips, mn10300, nios2, score and vax.  cris
complains with "tmpdir/textrel.o, section .rodata: relocation
R_CRIS_32 should not be used in a shared object; recompile with -fPIC"
so I've marked it as an xfail.

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.

	* elf-bfd.h (struct elf_link_hash_entry): Add is_weakalias.
	Rename u.weakdef to u.alias and update comment.
	(weakdef): New static inline function.
	* elflink.c (bfd_elf_record_link_assignment) Test is_weakalias
	rather than u.weakdef != NULL, and use weakdef function.

	u.alias.  Update comments.

	u.weakdef != NULL and use weakdef function.
	* elf-m10300.c (_bfd_mn10300_elf_adjust_dynamic_symbol): Test

a2f63b2e7a ELF/BFD,GDB: Handle both variants of the 32-bit Linux core PRPSINFO note 
Fix commit 70a38d42c5 ("New entry points for writing Linux NT_PRPSINFO
notes."), <https://sourceware.org/ml/binutils/2013-02/msg00023.html>,
and commit b3ac9c7756 ("Put more info in NT_PRPSINFO Linux notes"),
<https://sourceware.org/ml/binutils/2013-02/msg00024.html>, and handle
both variants of the 32-bit Linux core PRPSINFO note across all targets.

The 32-bit Linux core PRPSINFO note matches the 32-bit kernel structure,
defined as follows:

(gdb) ptype struct elf_prpsinfo
type = struct elf_prpsinfo {
    char pr_state;
    char pr_sname;
    char pr_zomb;
    char pr_nice;
    unsigned long pr_flag;
    __kernel_uid_t pr_uid;
    __kernel_gid_t pr_gid;
    pid_t pr_pid;
    pid_t pr_ppid;
    pid_t pr_pgrp;
    pid_t pr_sid;
    char pr_fname[16];
    char pr_psargs[80];
}
(gdb)

where the individual data types of most members are the same across all
32-bit Linux ports, with the exception of `__kernel_uid_t' and
`__kernel_gid_t'.  These are defined in <asm-generic/posix_types.h> as
32-bit `unsigned int' by default, however overridden as 16-bit `unsigned
short' in port-specific <asm/posix_types.h> for a few targets, mostly
earlier ports of Linux, specifically: ARM, CRIS, FR-V, M32R, m68k,
MN10300/AM33, s390, SuperH, SPARC and i386.

The default is the same as the PowerPC variant already handled, as from
the commits referred.  Make the special PowerPC case generic then,
removing the GDB part, and provide a backend flag to switch between the
two cases possible, with the 32-bit one being the default and the 16-bit
one explicitly selected.  Set the flag in the target backends affected.

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.
	* elf64-ppc.c (ppc64_elf_copy_indirect_symbol): Likewise.

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.
