Max Filippov e7d17e71cd Fix xtensa ld segfault when linking linux modules
is_inconsistent_linkonce_section makes an assumption that section name
that starts with ".gnu.linkonce.prop." has one more dot in its suffix.
However gas generates such section name by insertion of "prop." right
after ".gnu.linkonce." part of the name of the original section. So, for
section named ".gnu.linkonce.this_module" corresponding property section
name does not satisfy the assumption. Such section names are common in
linux modules. This bug was exposed by the patch "a35d5e8 Fix alignment
for the first section frag on xtensa", that makes gas produce property
section for each section that has ".align" directive in it.

Use suffix that immediately follows ".gnu.linkonce.prop." when there are
no more dots following it.

ld/
    * emultempl/xtensaelf.em (is_inconsistent_linkonce_section):
    correctly handle missing dot in section name after
    ".gnu.linkonce.prop.".

Alan Modra 7341d5e22f Add symbols for global entry stub, and report stats
The undefined function symbols (with non-zero value) on global entry
stubs are discarded by objdump when disassembling, so give objdump
another symbol to mark the stubs.

Also fixes a couple of bugs:
- entry_section was set to .opd for ELFv2, which meant a hard error
  rather than a warning when _start wasn't defined.
- global entry stubs were not built if they were the only type of
  stub in an executable.

bfd/
	* elf64-ppc.c (ppc_stub_type): Add ppc_stub_global_entry.
	(struct ppc_link_hash_table): Increase size of stub_count array.
	(build_global_entry_stubs): Emit symbol on global entry stub.
	(ppc64_elf_build_stubs): NULL check htab->brlt.  Add global entry
	stub stats.
ld/
	* emultempl/ppc64elf.em (stub_added): Delete.
	(gld${EMULATION_NAME}_finish): Call ppc64_elf_build_stubs even when

	for ELFv1.

Linda Zhang eeb14e5a5b Change the default behaviour of the PE targeted linker so that timestamps are
inserted.  This is for compatibility with other, non-GNU tools.  Deterministic
binaries can still be created by using the new --no-insert-timestamp command line
option.

	* emultempl/pe.em: Initialise insert_timestamp to true.
	Add a --no-insert-timestamp command line option.
	* emultempl/pep.em: Likewise.
	* ld.texinfo: Document that --insert-timestamp is enabled by
	default and that it now has an inverse command line option.
	* NEWS: Mention the new behaviour.

Alan Modra 93d1b056cb Rewrite ppc32 backend .sdata and .sdata2 handling
1) _SDA_BASE_ and _SDA2_BASE_ and defined automatically, in a similar
   manner to the way _GLOBAL_OFFSET_TABLE_ is handled.  It's a little
   more complicated to remove the symbols because _SDA_BASE_ needs to
   be there if either .sdata or .sbss is present, and similarly for
   _SDA2_BASE.
2) The linker created .sdata and .sdata2 sections used for
   R_PPC_EMB_SDAI16 and R_PPC_EMB_SDA2I16 pointers are created early.
   Nowadays we strip unneeded sections from the output, so it isn't
   necessary to delay creating the sections.
3) The output section for targets of various SDA relocs is now checked
   as per the ABI(s).  We previously allowed .sdata.foo and similar,
   most likely because at some stage we were checking input sections.

Also, the patch fixes a long-standing bug in size_input_sections
that affects the values of symbols defined in stripped input
sections.

Alan Modra b4ab436423 ppc476 icache workaround fix for bctr
I got the ppc476 workaround wrong.  bctr (and bctrl) as the last
instruction in a page can hit the icache bug if the preceding mtctr
insn is close by, and the destination is in the first few instructions
on the next page.  This scenario can occur with code generated by gcc
to implement switch statements, or in code generated to call by
function pointer.

To prevent the bctr problem it is also necessary to remove other
instructions that otherwise would be safe.

Nick Clifton 76f0cad6f4 This is a fix for PR ld/16744 which showed that an object file linked with -r and -z [no]execstack

Nick Clifton 5063daf735 This patch adds a default manifest in to the final links performed by the Cygwin and MinGW targets.
The manifest is necessary in order for the linked binaries to be executed in a Windows 8 environment.

The manifest is added using a linker script so that this feature will be compiler-neutral.  The resource
merging code in the linker means that if an application provides its own manifest then the default
manifest will be ignored.

Alan Modra 7d4c687d56 Control powerpc64-ld provision of register save/restore
This patch allows the user to override powerpc64-ld's default for
providing linker generated register save and restore functions as used
by gcc -Os code.  Normally these are not provided by ld -r, so Linux
kernel modules have needed to include their own copies.

bfd/

	* elf64-ppc.c (ppc64_elf_func_desc_adjust): Use it to control

Moves assorted variables used to communicate between ld and bfd into

Alan Modra 668e22e51b ppc476 workaround for ld -r fixes
This fixes the glaring error that the ppc476 workaround wasn't
actually enabled for ld -r, and adjusts relocations to match moved
code.

bfd/

Alan Modra 795bc6b3ea Enable ppc476 workaround for ld -r.
The Linux kernel builds modules using ld -r.  These might need the
ppc476 workaround, so enable it for ld -r if sections have sufficient
alignment to tell location within a page.

bfd/
	* elf32-ppc.c (ppc_elf_relax_section): Enable ppc476 workaround
	for ld -r, when code sections are sufficiently aligned.

Alan Modra 5446cbdf82 ppc476 icache bug workaround
This implements a work-around for an icache bug on 476 that can cause
execution of stale instructions when control falls through from one
page to the next.  The idea is to prevent such fall-through by
replacing the last instruction on a page with a branch to a patch
area containing the instruction, then branch to the next page.

The patch also fixes a number of bugs in the existing support for long
branch trampolines.

	(ppc_elf_tls_setup): Remove no_tls_get_addr_opt parameter.
	(ppc_elf_size_dynamic_sections): Align __glink_PLTresolve to
	64 bytes for ppc476 workaround.
	(struct ppc_elf_relax_info): New.
	(ppc_elf_relax_section): Exclude linker created sections and
	those too small to hold one instruction.  Don't add another
	branch 	around trampolines on later relax passes.  Don't
	generate trampolines for undefined symbols when !relocatable,
	nor for plugin symbols.  Allocate space for ppc476 workaround
	patch area.  Free fixups on error return path.

Alan Modra 4199e3b866 non-PIC references to __ehdr_start in pie and shared
Rather than hacking every backend to not discard dynamic relocations
against an undefined hidden __ehdr_start, make it appear to be defined
early.  We want __ehdr_start hidden before size_dynamic_sections so
that it isn't put in .dynsym, but we do need the dynamic relocations
for a PIE or shared library with a non-PIC reference.  Defining it
early is wrong if we don't actually define the symbol later to its
proper value.  (In some cases we want to leave the symbol undefined,
for example, when the ELF header isn't loaded, and we don't have this
infomation available in before_allocation.)
