9c5cee130f Pull in a fix (still under GPLv2) for a double free in gdb, leading to
an assert, which can occur if you repeatedly dlopen() and dlclose() a
.so file in a tight loop.  This was reported on freebsd-current@ by
Alexandre Martins, with a sample to reproduce the behaviour.

c81c8b1a46 - Check on target wordsize instead of compile time define if we build on
64-bit PowerPC or 32-bit PowerPC.
- Make gdb work on powerpc64, the code for this is obtained from
  ppc-linux-tdep.c.
- Remove non-elf core read functionality. Implement core read functionality
  similar like other FreeBSD targets.
- Set long double limitations.

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.

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.

6c412cffd0 Fix reading of .debug_line on MIPS64, big-endian:
read_initial_length detects pointer size by checking first
    4 bytes of .debug_line and stores it in struct comp_unit_head *
    passed to it as second argument. By passing NULL to a
    read_initial_length we ignore actual pointer size (8 bytes) and
    use default (4 bytes) which results in wrong offsets of header fields.

2cf64c8006 Teach our toolchain how to generate 64-bit PowerPC binaries. This fixes
a variety of bugs in binutils related to handling of 64-bit PPC ELF,
provides a GCC configuration for 64-bit PowerPC on FreeBSD, and
associated build systems tweaks.

f6d2be2556 gdb: Remove arm_pc_is_thumb_dummy() and related code.
This is basically an import of the following gdb change:
http://sourceware.org/ml/gdb-cvs/2005-03/msg00143.html (which in effect fixes
problems with gracefully closing down the non-Thumb program being debugged).

78cf5f2fcd Abstract the handling of dirty stacked registers in ia64_read_reg() and
ia64_write_reg() and call these whenever we read or write registers from
and to memory. This way we correctly read registers from addresses in
the register cache and thus fixes backtraces when the saved registers
(such as rp and ar.pfs) are in dirty stacked registers.

4fd6e2a0c9 Various improvements for ia64:
o  s/TARGET_XFER_DIRTY/NATIVE_XFER_DIRTY/g to be conformant,
o  Handle TARGET_OBJECT_DIRTY for core files. Required on Linux,
o  Replace ia64_fbsd_supply_fpregs() and ia64_fbsd_supply_gregs()
   with supply_fpregset() and supply_gregset() resp. Needed to
   support libthread_db.
o  For target_read_partial(), pass the address of bspstore as the
   annex instead of bspstore itself. This fixes crossbuilds. The
   annex is a pointer, while bspstore is a ULONGEST.
o  In ia64_frame_prev_register(), handle dirty stacked registers.
