[PATCH 0/4] make probes independent of the program space


This patch series changes SystemTap probes to be independent of the
program space, and then to be stored in the per-BFD object.  That way,
they can be shared by all objfiles referring to a given BFD.  This
saves memory and perhaps a bit of time, in the multi-inferior case.

This is based on my similar patch series to make minimal symbols
independent of the program space:

This is part of the obj file splitting project:

I built and regtested the series on x86-64 Fedora 18.
