Is this is a regression, or did it never work?

it never work.it can run application 、attach process;bur can not sniff corefile
bfd.I noticed that in ia64-hpux platform gdb donot call
set_gdbarch_regset_from_core_section、 deprecated_add_core_fns Interface.Does
this mean that gdb does not support ia64-hpux? Is there any way to solve this
problem?(In reply to comment #1)

gdb/utils.h contains a forward declaration of type "enum errors", and this
causes a build failure with old GCC compilers. I suspect the same is true of
non-GNU compiler, as enum forward declarations are a GNU extension.

Ref: http://www.sourceware.org/ml/gdb-patches/2013-04/msg00829.html

A fix was checked it at:
http://www.sourceware.org/ml/gdb-patches/2013-05/msg00522.html

This PR is to backport the patch to the GDB 7.6 branch.

By "never worked" I mean, did this work with previous GDB releases.

Sounds like core file debugg support for ia64-hpux is not implemented.
The way to solve it, would be to implement it.  :-)

I'd guess it'd be easy to copy from the hppa-hpux support.

  i think they are different, IA64 and PA register structure.Can find a version
that support for ia64-hpux?
