Hi, Ahmed.

Yo= u outlined the envisioned user workflow regarding this script in your repor= t. As I understand it, it generally goes like this:

1) The user first discovers helpers, and their performance data.2) The user examines the callees of a particular helper of choice (usuall= y, the most instruction-consuming helper).
3) The user perhaps fu= rther examines a callee of a particular callee of the particular helper.
4) The user continues this way until the conclusion can be drawn, o= r maximal depth is reached.

The procedure might be= time consuming since each step requires running an emulation of the test p= rogram.

This makes me think that the faster and ea= sier tool for the user (but, to some, not that great, extent, harder for yo= u) would be improved list_helpers.py (and list_fn_calees.py) that provides = list of all callees for all helpers, in the tree form (so, callees of calle= es, callees of callees of callees, etc.),=C2=A0rather than providing just a= list of immediate callees, like it currently does.

I think you can provide such functionality relatively easily using recurs= ion. See, let's say:



For printing trees like this:

=
foo
=E2=94=9C=E2=94=80=E2=94=80 bar
=E2=94=82 =E2=94=9C=E2=94=80=E2=94=80 a
=E2=94=82 =E2=94=94=E2=94=80=E2=94=80 b
=E2=94=9C=E2=94=80=E2=94=80 baz
=E2=94=94=E2=94=80=E2=94=80 qux
=E2=94=94=E2=94=80=E2=94=80 c=E2=8F=8E
d

you c= an potentialy use tree-format library:

=C2=A0
Pe= rhaps you can have a switch (let's say, --tree <yes|no>) that spe= cifies whether the script outputs just immediate callee list, or entire cal= lee tree.

Thanks,
Aleksandar
