Fwd: how to determine location of source?

[Brendan Miller <catphive@catphive.net>]

Er, I meant to send this to the GDB list originally so I could clarify
what I'm trying to do.

Right, but before I can use that I need to know what the original path
was so I can do the substitution. My binaries come from a daily build,
and I can't know what particular path the build machine made them on
without inspecting the binaries themselves.

I did read the gdb documentation here, scroll down to the Specifying
Source Directories section:
http://sourceware.org/gdb/download/onlinedocs/gdb_8.html#SEC51

which is why I was posting on the list, because the documentation is
incomplete, or maybe I just missed something. It says that GDB
inspects the source path embeded in the binary, but I can't find where
it says how the user can do it.
