fd67aa1129 Update year range in copyright notice of binutils files
Adds two new external authors to etc/update-copyright.py to cover
bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then
updates copyright messages as follows:

1) Update cgen/utils.scm emitted copyrights.
2) Run "etc/update-copyright.py --this-year" with an extra external
   author I haven't committed, 'Kalray SA.', to cover gas testsuite
   files (which should have their copyright message removed).
3) Build with --enable-maintainer-mode --enable-cgen-maint=yes.
4) Check out */po/*.pot which we don't update frequently.

226f9f4fad Rename bfd_bread and bfd_bwrite
These were renamed from bfd_read and bfd_write back in 2001 when they
lost an unnecessary parameter.  Rename them back, and get rid of a few
casts that are only needed without prototyped functions (K&R C).

ae33771224 PR30697, ppc32 mix of local-dynamic and global-dynamic TLS
This fixes miscounting of dynamic relocations on GOT entries when
a) there are both local-dynamic and global-dynamic tls accesss for a
   given symbol, and
b) the symbol is global with non-default visibility, and
c) the __tls_get_addr calls aren't optimised away.

6f860418d5 asprintf memory leaks
A number of backends want to return bfd_reloc_dangerous messaqes from
relocation special_function, and construct the message using asprintf.
Such messages are not freed anywhere, leading to small memory leaks
inside libbfd.  To limit the leaks, I'd implemented a static buffer in
the ppc backends that was freed before use in asprintf output.  This
patch extends that scheme to other backends using a shared static
buffer and goes further in freeing the buffer on any bfd_close.

The patch also fixes a few other cases where asprintf output was not
freed after use.

93c6e8c3c1 PR30326, uninitialised value in objdump compare_relocs
This is a fuzzing PR, with a testcase involving a SHF_ALLOC and
SHF_COMPRESSED SHT_RELA section, ie. a compressed dynamic reloc
section.  BFD doesn't handle compressed relocation sections, with most
of the code reading relocs using sh_size (often no bfd section is
created) but in the case of SHF_ALLOC dynamic relocs we had some code
using the bfd section size.  This led to a mismatch, sh_size is
compressed, size is uncompressed, and from that some uninitialised
memory.  Consistently using sh_size is enough to fix this PR, but I've
also added tests to exclude SHF_COMPRESSED reloc sections from
consideration.

81ff113f78 Test SEC_HAS_CONTENTS before reading section contents
bfd_malloc_and_get_section does size sanity checking before allocating
memory and reading contents.  These size checks are not done for bss
style sections, because they typically don't occupy file space and
thus can't be compared against file size.  However, if you are
expecting to look at something other than a whole lot of zeros, don't
allow fuzzers to avoid the size checking.

8478900290 ppc32 and "LOAD segment with RWX permissions"
When using a bss-plt we'll always trigger the RWX warning, which
disturbs gcc test results.  On the other hand, there may be reason to
want the warning when gcc is configured with --enable-secureplt.
So turning off the warning entirely for powerpc might not be the best
solution.  Instead, we'll turn off the warning whenever a bss-plt is
generated, unless the user explicitly asked for the warning.

	no_warn_rwx_segments on generating a bss plt, unless explicity

This makes the default for ppc to keep dynamic relocs on undefweak

0f68420117 elf_backend_relocate_section int vs. bfd_boolean
This functions was changed to return an int in commit ece5ef6079 but
since bfd_boolean was an int typedef I lazily left all the ELF
relocate_section functions as returning bfd_boolean, except the SPU
one.  In order to use _Bool or bool in place of bfd_boolean we need to
be fussy about the return types.

252dcdf432 PowerPC TPREL_HA/LO optimisation
ppc64 ld optimises sequences like the following
	addis 3,13,wot@tprel@ha
	lwz 3,wot@tprel@l(3)
to
	nop
	lwz 3,wot@tprel(13)
when "wot" is located near enough to the thread pointer.
However, the ABI doesn't require that R_PPC64_TPREL16_HA always be on
an addis rt,13,imm instruction, and while ld checked for that on the
high-part instruction it didn't disable the optimisation on the
low-part instruction.  This patch fixes that problem, disabling the
tprel optimisation globally if high-part instructions don't pass
sanity checks.  The optimisation is also enabled for ppc32, where
before ld.bfd had the code in the wrong place and ld.gold had it in a
block only enabled for ppc64.

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.

EF_PPC_RELOCATABLE and similar flags, if present in an input shared

This patch is in preparation for a change to that.

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.

24872cb302 Minor fix for R_PPC_VLE_ADDR20
It is incorrect to "continue" in the ppc_elf_relocate_section reloc
processing loop except when editing or deleting relocs.  The normal
loop processing arranges to write the relocs if shuffling them over a
deleted entry.  Deleting only happens for debug sections currently and
those sections won't contain R_PPC_VLE_ADDR20 relocs, so this patch
doesn't fix a bug that would trigger with any normal object file.
