dtrace discuss - Dec 2005 - Need Provider for Register Window Spillage

Hi Pat,

There isn''t a provider yet that will let you examine those types of
traps.
YOu can use trapstat(1M) to see if the application is generating a bunch
of spill/fill traps which could confirm your hypothesis.

From out of the blue........

Is there a provider for telling me (on a SPARC machine) when and how 
often I''m getting register window spillage? For a customer app I want
to
know if the  massive amount of recursion he might be (or is) doing is 
causing us to spill and fill the register windows, with the associated 
performance hit.

Thanks,
Pat
