b531344c34 PR ld/20828: Reorder the symbol sweep stage of section GC
Complement commit 81ff47b3a5 ("PR ld/20828: Fix linker script symbols
wrongly forced local with section GC") and move the symbol sweep stage
of section GC from `elf_gc_sweep' to `bfd_elf_size_dynamic_sections',
avoiding the need to clear the `forced_local' marker, problematic for
targets that have special processing in their `elf_backend_hide_symbol'
handler.  Set `mark' instead in `bfd_elf_record_link_assignment' and,
matching changes from commit 3bd43ebcb6 ("ld --gc-sections fail with
__tls_get_addr_opt"), also in PowerPC `__tls_get_addr_opt' handling
code, removing a:

FAIL: PR ld/20828 dynamic symbols with section GC (version script)

test suite failure with the `score-elf' target.

The rationale is it is enough if symbols are swept at the beginning of
`bfd_elf_size_dynamic_sections' as it is only in this function that the
size of the GOT, the dynamic symbol table and other dynamic sections is
determined, which will depend on the number of symbols making it to the
dynamic symbol table.  It is also appropriate to do the sweep at this
point as it is already after any changes have been made to symbols with
`bfd_elf_record_link_assignment', and not possible any earlier as calls
to that function are only made just beforehand -- barring audit entry
processing -- via `gld${EMULATION_NAME}_find_statement_assignment'
invoked from `gld${EMULATION_NAME}_before_allocation' which is the ELF
handler for `ldemul_before_allocation'.

f0158f4416 PowerPC dynamic relocations
This patch fixes a number of issues with powerpc dynamic relocations.

1) Both ppc and ppc64 were emitting more dynamic symbols and
relocations than necessary, due to not supporting static linker
resolution of tls_index entries for __tls_get_addr_opt.  This meant
that any @got@tlsgd or @got@tlsld reloc needed to make their symbols
dynamic and generate dptmod and dtprel relocs for the dynamic linker.
That would have been passable, but what happened was that practically
all @got relocations resulted in their symbols being made dynamic and
dynamic relocations emitted against the GOT entries.  (Mostly visible
on ppc32 executables since ppc64 gcc really only uses @got style
relocs for TLS.)

2) The PowerOpen syntax was not supported with __tls_get_addr_opt.
DTPMOD/DTPREL relocs on tls_index TOC entries did not use the trick of
forcing dynamic symbols and relocations so those entries always
resulted in the full __tls_get_addr processing.  gcc doesn't use the
PowerOpen syntax for TLS, and normally such code would be optimized to
TLS IE or LE so the impact of missing this support was minimal.

3) In an executable, relocations against GNU indirect functions always
used the value of their PLT stub.   While this is correct, it is
better in some cases to use a dynamic relocation.  An extra dynamic
relocation can mean that calls via function pointers need not bounce
through the PLT stub at runtime.

The patch also tidies the PLT handling code in ppc32
allocate_dynrelocs.  Allocating PLT entries after other dynamic relocs
allows the PLT loop to omit special handling for undefined weak
symbols, and that in turn allows the loop to be simplified.

81ff47b3a5 PR ld/20828: Fix linker script symbols wrongly forced local with section GC
Fix a generic ELF linker regression introduced with a chain of changes
made to unused input section garbage collection:

- commit 1a766c6843 ("Also hide symbols without PLT nor GOT
  references."),
  <https://sourceware.org/ml/binutils/2011-09/msg00076.html>,

- commit 1d5316ab67 ("PR ld/13177: garbage collector retains zombie
  references to external libraries"),
  <https://sourceware.org/ml/binutils/2011-10/msg00161.html>,

- commit 6673f753c0 ("Fix PR 12772, garbage collection of dynamic
  syms"), <https://sourceware.org/ml/binutils/2011-12/msg00077.html>,

causing the garbage collection of unused symbols present in a DSO
involved in a link to make identically named symbols ordinarily defined
(i.e. not hidden or PROVIDEd) by a linker script local, even though the
latter symbols are supposed to be global as if no DSO defined them as
well.

This is because linker script assignments are processed very late as
`lang_process' proceeds, down in the call to `ldemul_before_allocation',
which is made after the call to `lang_gc_sections' to do input section
garbage collecting.  Consequently if unused, then any such DSO-defined
symbol has already been garbage-collected and internally marked local.
It would ordinarily be removed from dynamic symbol table output, however
a linker script assignment correctly replaces its original definition
with the new one and enters it into the dynamic symbol table produced as
it is supposed to be exported.  The original local marking is however
retained making the symbol local in the dynamic symbol table and
therefore not available externally.  This also causes a sorting problem
with the MIPS target, which does not expect non-section local dynamic
symbols to be output and produces an invalid binary.

Fix the problem then, by removing the `forced_local' marking for the
offending case and add suitable test cases.  First to verify that unused
symbols ordinarily defined with linker script assignments remain
exported in the context of input section garbage collection whether or
not a DSO defining identically named symbols is present in the link.
Second that a linker version script still correctly retains or removes
such symbols as requested.

.eh_frame covering the .plt section.

	* elf32-i386.c (elf_i386_size_dynamic_sections): Set
	plt_eh_frame->size to eh_frame_plt_size and use eh_frame_plt.

ae4fda6638 bfd: alpha: Fix crash caused by double free with --no-keep-memory
Without this, ld has been seen to crash in libc when freeing tsec_free:

*** Error in `/usr/bin/ld': double free or corruption (!prev): 0x0000000120ceb6a0 ***

_bfd_elf_link_read_relocs will always return the cached value if
present, even if keep_memory is false, therefore setting tsec_free to
NULL only when keep_memory is true is not sufficient.

	* elf64-alpha.c (elf64_alpha_relax_opt_call): Don't set tsec_free
	if relocs are cached.
