Description

Generation of -TP output relies on trace instructions being compiled into the stylesheet, and these instructions are not exported when generating a SEF file. This means it is not possible to compare the profile for the SEF and non-SEF cases.

Also, -TP output is incomplete if tail call optimisation is enabled. See bug #4867.

Decided to close this as unresolved. It's inherent to the way that tracing is implemented, and I don't think it's a major problem in practice.
