b5eb05bb72 In the upstream rev. 1.61 of elf64-sparc.c the following bug was fixed:
* elf64-sparc.c (sparc64_elf_relocate_section): Adjust addend of
        dynamic relocs against section symbols for the output section vma.

However, with the addition of TLS support in the upstream rev. 1.104
this fix was essentially reverted. After factoring out the common parts
of elf32-sparc.c and elf64-sparc.c a comment was added to elfxx-sparc.c
in the upstream rev. 1.27 as part of unrelated changes, saying that the
fix from elf64-sparc.c rev. 1.61 indeed should be implemented, but given
that some unspecified OS has a broken ld.so expecting broken relocations
deliberately is omitted.
As the current behavior actually violates the SPARC ABI, FreeBSD never
had such a broken ld.so and this is actually causing problems with at
least kernel modules linked with binutils 2.17.50 committed in r218822
without the workaround committed in r219340 in place, re-implement the
above fix in a way so that is only applied if the output format is
ELFOSABI_FREEBSD. In the upstream version it probably would make sense
to invert this check and only skip adjusting the addend for the OS with
the broken ld.so, once it's determine which one that is.

ce8fb93178 Merge binutils 2.17.50 to head. This brings a number of improvements to
x86 CPU support, better support for powerpc64, some new directives, and
many other things.  Bump __FreeBSD_version, and add a note to UPDATING.

Thanks to the many people that have helped to test this.

434efabd4c On PowerPC64, linker emits a fake object into each linked object,
'linker stubs'. Add .note.GNU-stack for the stubs objects. Without this,
final binary will have RWE mode for PT_GNU_STACK regardless of the
actual requirements.

aa2526259b Try a more generic version of the last two fixes. Assuming this is correct,
it should also be MI. The problem here arises when ld ends up linking a
link-once section with relocations against sections that point back to it
that are as yet unresolved. Instead of piecemeal finding sections we
think are potentially subject to this issue, just defer processing for
sections that have yet to be relocated instead of immediately bailing.

7f08176ee8 Add the ability for GDB to printout the thread name along with other
thread specific informations.

In order to do that, and in order to avoid KBI breakage with existing
infrastructure the following semantic is implemented:
- For live programs, a new member to the PT_LWPINFO is added (pl_tdname)
- For cores, a new ELF note is added (NT_THRMISC) that can be used for
  storing thread specific, miscellaneous, informations. Right now it is
  just popluated with a thread name.

GDB, then, retrieves the correct informations from the corefile via the
BFD interface, as it groks the ELF notes and create appropriate
pseudo-sections.

517d9fc653 binutils/ld: fix incorrect placement of __start_SECNAME in some cases
__start_SECNAME and __stop_SECNAME symbols are automatically generated
by ld for orphan sections, i.e. those not explicitely referenced by a
linker script.  The symbols are supposed to be placed correspondingly
at the start and the end of the section in output file.  In some cases
__start_SECNAME may be placed at the address after the end of the
previous section (if any) and before the start the section.  This
happens when following conditions are met:
1. the orphan section is found in more than one input file
2. the orphan section has different alignment requirements across input
files
3. the first instance of the section encountered doesn't have the
greatest alignment requirement
In these conditions resulting output section will be placed at address
after the end of the previous section aligned to the greatest alignment
requirement in the inputs, but __start_SECNAME will be placed at address
after the end of the previous section aligned to the alignment
requirement of the first input in which the section is encountered.

See commit message of r196118 for a concrete example of problems caused
by this bug.

The fix is to place __start_SECNAME inside the section and use ABSOLUTE
directive, rather than placing __start_SECNAME outside the section and
trying to guess address alignment.

This fix is in line with upstream binutils change/fix made between
versions 2.19 and 2.20 in revision of 1.307 ldlang.c.

5619a3e4bf Add/improve mips64r2, Octeon, n32 and n64 support in the toolchain.
o) Add TARGET_ABI to the MIPS toolchain build process.  This sets the default
   ABI to one of o32, n32 or n64.  If it is not set, o32 is assumed as that is
   the current default.
o) Set the default GCC cpu type to any specified TARGET_CPUTYPE.  This is
   necessary to have a working "cc" if e.g. mips64 is specified, as binutils
   will refuse to link objects using different ISAs in some cases.
o) Add support for n32 and n64 ABIs to binutils and GCC.
o) Add additional required libgcc2 stubs for n32 and n64.
o) Add support for the "mips64r2" architecture to GCC.  Add the "octeon"
o) When static linking, wrap default libraries in --start-group and
   --end-group.  This is required for static linking to work on n64 with the
   interdependencies between libraries there.  This is what other OSes that
   support n64 seem to do, as well.
o) Fix our GCC spec to define __mips64 for 64-bit targets, not __mips64__, the
   former being what libgcc, etc., check and the latter seemingly being a
   misspelling of a hand merge from a Linux spec.
o) When no TARGET_CPUTYPE is specified at build time, make GCC take the default
   ISA from the ABI.  Our old defaults were too liberal and assumed that 64-bit
   ABIs should default to the MIPS64 ISA and that 32-bit ABIs should default to
   the MIPS32 ISA, when we are supporting or will support some systems based on
   earlier 32-bit and 64-bit ISAs, most notably MIPS-III.
o) Merge a new opcode file (and support code) from a later version of binutils
   and add flags and code necessary to support Octeon-specific instructions.
   This should also make merging opcodes for other modern architectures easier.
