-t Display subroutine call tree to stdout. Subroutine statistics are
not displayed. When a function is called multiple consecutive
times at the same calling level then it is displayed once with a
repeat count.
-S Display merged subroutine call tree to stdout. Statistics are
displayed for each branch of the tree.
When a function is called multiple (not necessarily consecutive)
times in the same branch then all these calls go into one branch
of the next level. A repeat count is output together with com-
bined inclusive, exclusive and kids time.
Branches are sorted w.r.t. inclusive time.
