Package: emacs
Tags: patch
Severity: wishlist

GUD-MI's disassembly buffer only works when the current frame has debug
information. While debugging dynamically generated code it'd be useful
to simply follow the program counter. I understand that newer GDBs
expose an API that lets a JIT compiler register debug information for
dynamically generated code, but JITs typically only do so for real
functions. So, having the disassembly buffer follow $PC would still be
useful while stepping through dynamically generated, shorter sequences
of code (like call stubs, inline caches etc.). 

The latest GDB (7.4.50.20120122-cvs) does this in its TUI mode while my
stable GDB's (7.0.1-debian) behavior is the same as Emacs 23 GUD.

Please review and merge.

         Thanks,

Thanks; applied.
It would be great if you could also suggest ChangeLog entries for any
future changes.
Also, we'll need a copyright assignment to accept any further changes of
more than a few lines total from you. It's a straightforward procedure.
Let me know off-list if you want to, and I can send you the form.
