A recent Fedora bug (1520805) exposed a problem with objcopy's reloc
copying code, when a binary also contains mergeable notes. The note
merging code would delete some relocs, but then the reloc copying code
would try to put them back again, which did not work.
So I am checking in the patch below to fix the problem. The patch
also tweaks one of the binutils note merging tests so that it is
skipped for the Sparc64 target, since this has funky relocs.
binutils * objcopy.c (copy_relocations_in_section): Use the orelocations
field of the input section, if it has been initialised.
* testsuite/binutils-all/note-2-64.d: Skip test on Sparc64.
bfd * elfcode.h (elf_write_relocs): Check for an empty howto field.
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.

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.

This patch processes linker script assignment statements before ld
opens DT_NEEDED libraries, in order to define symbols like __bss_start
that might also be defined by a library, falsely triggering an error
about "DSO missing from command line".
The initial value won't be correct when assigning a symbol from dot,
and I make no attempt to handle all expressions. For example, an
assignment like "_start_foo = ADDR (.foo)" isn't valid until sections
are laid out, so won't define _start_foo early. What's here should be
enough for most common scripts, and hopefully won't perturb fragile
scripts.

There is a call to update_definedness between code that evaluates an
assignment expression value and code that transfers symbol
attributes. When script assignment expressions contain DEFINED, that
can mean the wrong symbol type is copied. This patch tracks symbols
read during expression evaluation, rather than examining the
expression and re-evaluating conditionals. Not only does this
simplify the code, it also means ld can now copy symbol types in more
complex expressions.
An unfortunate side effect of copying symbol type for more complex
expressions affects mmix, which uses
PROVIDE (Main = DEFINED (Main) ? Main : (DEFINED (_start) ? _start : _start.));
in a default script. So now _start or _start. symbol type may be
copied, losing the function type specially set up for Main. This can
be avoided by making bfd_copy_link_hash_symbol_type do nothing for
mmix.

CORE PT_NOTE segments may have p_align values of 0 or 1. gABI specifies
that PT_NOTE alignment should be aligned to 4 bytes for 32-bit objects
and to 8 bytes for 64-bit objects. If segment alignment is less than 4,
we use 4 byte alignment.
This reverts commit 650444eb54.
With this patch, running the GDB test case gdb.base/auxv.exp is stuck in
an infinite loop, consuming memory to the point that it renders the
machine unusable. I am reverting it so we can take our time to
investigate while not killing all the developers' machines.
According to gABI, in a note entry, the note name field, not note name
size, is padded for the note descriptor. And the note descriptor field,
not note descriptor size, is padded for the next note entry. Also notes
are aligned to 4 bytes in 32-bit objects and 8 bytes in 64-bit objects.
Since on Linux, .note.ABI-tag and .note.gnu.build-id notes are always
aligned to 4 bytes, we need to use alignment of note section or note
segment, instead of assuming alignment based on ELF file class.

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.
