------- Additional Comments From mhiramat at redhat dot com  2007-10-08 16:49 -------
I'm interested in this feature.

As far as I understand, with this feature, systemtap treats the next script ;
---
 probe ALIAS=PROBEPOINT { stmt1; }
 probe ALIAS if (expr) { stmt2; }
---
as
---
 probe PROBEPOINT { if (!expr) next; stmt1; stmt2}
---

In that case, 
---
 probe ALIAS=PROBEPOINT { stmt1; }
 probe ALIAS if (expr) { stmt2; }
 probe ALIAS { stmt3; }
---
will be treated as
---
 probe PROBEPOINT { if (!expr) next; stmt1; stmt2}
 probe PROBEPOINT { stmt1; stmt3}
---
Is that right?
