gdb/gdb-rhbz795424-bitpos-12of25.patch
Stephan Kulow 16b5661a6f Accepting request 147743 from devel:gcc
- 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.
