Description Frank Ch. Eigler 2005-08-29 21:33:17 UTC 
It might be nice to have a translator option that inserts tracing calls into the
C code, so a programmer wishing to debug his systemtap script can watch it work
statement by statement.  A naive form could generate a flood of tracing traffic.
 A smarter form may pass tokens identifying the statement/subexpression in a
compact way, relying on stpd to decode it.  Think "branch history buffer".

See the way that c->last_stmt is set throughout translated code.
A sibling array could accumulate codes that stand for those same points.

This doesn't sound like such a good idea any more.
