[PATCH 00/10] Unwinder interface consolidation

[Florian Weimer]

This series is basically a repost.  I had to tweak it somewhat to pick
up the <unwind-arch.h> customization for MIPS.  I switched to reusing
that header for all customization.

This is a prequiste for consolidating and libc and nptl implementations
of unwinding, and moving the cancellation implementation into libc.

Thanks,
Florian

Florian Weimer (10):
  Implement <unwind-link.h> for dynamically loading the libgcc_s
    unwinder
  backtrace: Implement on top of <unwind-link.h>
  arm: Implement backtrace on top of <unwind-link.h>
  i386: Implement backtrace on top of <unwind-link.h>
  m68k: Implement backtrace on top of <unwind-link.h>
  sparc: Implement backtrace on top <unwind-link.h>
  __frame_state_for: Use <unwind-link.h> for unwinder access
  Move sysdeps/gnu/unwind-resume.c to sysdeps/generic/unwind-resume.c
  Implement _Unwind_Resume in libc on top of <unwind-link.h>
  nptl: Use <unwind-link.h> for accessing the libgcc_s unwinder
