[Kcachegrind-callgrind] meaning of "lr" in Source Code View

[Simon B. <sim...@gm...>]

Hi,

When I open a callgrind trace and go the the "Source Code" view, it
shows a column labelled "lr".
I have not found any documentation about this value. The numbers seem
to be very similar to the cycle estimate "CEst" which can be manually
selected in the View options.

Can you explain the difference between these two values?

I am using the 0.7.2kde version on Centos 7.

Thank you!

Regards,

Simon
