Re: Adding -file-list-exec-source-file command to GDB/MI

Hello Bob,

My approval isn't needed for these patches or anything, I'm just
an interested observer making comments.

I don't understand why this command is useful.

A UI can get the filename of the currently-executing source file
easily enough with "stack-list-frames 0 1".  The pathname is returned
as it was recorded in the debug info from the compiler - it might
be an absolute path or it might be a relative path.  

If the path is relative, gdb will interpret that pathname based on
the directory gdb was invoked--which presumably the UI did itself.
Or it will be interpreted relative to any paths added with the
"dir" (CLI) / "environment-directory" (MI) command, which the UI
would have added as well.  (or it can get the list of paths with
the environment-directory command without any arguments)

Why does this information have to be provided by gdb?
