- Merge from gdb-7.5.1-30.fc18.src.rpm.
  7.5.1 gives:
    * An "Attempt to dereference a generic pointer" errors (-var-create).
    * Backtrace problems on x32 (PR backtrace/14646).
    * next/step/finish problems on x32 (PR gdb/14647).
    * A "malformed linespec error: unexpected keyword, [...]" error
      (PR breakpoints/14643).
    * GDB crash while stepping through powerpc (32bits) code.
    * A failed assertion in linux_ptrace_test_ret_to_nx.
    * A "!frame_id_inlined_p (frame_id)" failed assertion.
    * A "No more reverse-execution history." error during reverse
      "next" execution (PR 14548).
    * Incomplete command descriptions in "apropos" output.
    * PR gdb/14494 (a GDB crash difficult to characterize).
  7.5 gives:
    * Go language support.
    * New targets (x32 ABI, microMIPS, Renesas RL78, HP OpenVMS ia64).
    * More Python scripting improvements.
    * SDT (Static Defined Tracing) probes support with SystemTap probes.
    * GDBserver improvements (stdio connections, target-side evaluation
      of breakpoint conditions, remote protocol improvements).
    * Other miscellaneous improvements (ability to stop when a shared
      library is loaded/unloaded, dynamic printf, etc).
    * Reverse debugging on ARM.

- Do not provide a custom (safe) auto-load dir.

Subject: [patch] Fix GNU/Linux core open: Can't read pathname for load map: Input/output error.
Hi,
[ New patch variant. ]
GDB currently always prints on loading a core file:
warning: Can't read pathname for load map: Input/output error.
The patch is not nice but it was WONTFIXed on the glibc side in:
http://sourceware.org/ml/libc-alpha/2009-10/msg00001.html
The same message in GDB PR 8882 and glibc PR 387 was for ld-linux.so.2 l_name
but that one is now ignored thanks to IGNORE_FIRST_LINK_MAP_ENTRY.
This fix is intended for Linux system vDSO l_name which is a second entry in
the DSO list.
Regression tested on {x86_86,x86_64-m32,i686}-fedora11-linux-gnu.
Thanks,
Jan

Do not print false warning on reading core file with vDSO on GNU/Linux.
* solib-svr4.c (svr4_current_sos): Suppress the warning if
MASTER_SO_LIST is still NULL.
* solib.c (update_solib_list): New variable saved_so_list_head.
Conditionally restart the function.
