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,
            -Kaushik
