Description
Model functions in 68_1 do not have ldv_ prefix. As a result, -fdepth may work incorrectly.
Updated by Vadim Mutilin about 13 years ago
- Status changed from New to Feedback
The upper level model functions can't have ldv_ prefix because they are linked (without asectator) and should have the same name. There are no other functions in the model except nondeterministic ones which already have ldv_ prefix.

If only the upper level functions don't have this prefix, it's OK then (and it looks just as if fdepth had one less level).
Actually, I think of trying to reimplement fdepth for it to only constrain function calls which do not contain error location somewhere in their call graph.

But what is about macrodefinitions?
Updated by Vadim Mutilin about 13 years ago
Macrodefinitions are not visible for BLAST

Some time ago we stated that non-aspectator rule instrumentor is as capable as plain C macrosubstitution. But macrosubstitution is not available in current implementation of non-aspectator rule instrumentor, is it?

Alexey, I didn't understand the question. It is not clear what do you mean by macrosubstitution. With non-aspect models we may freely use macro inside the model code, but can not connect (weave) model to the macro defined in the kernel headers.

I wonder why we cannot define a macro
#define usb_put_urb ldv_usb_put_urb
and have the upper level model functions with ldv_ prefix. Is it possible in non-aspect models now?
Updated by Evgeny Novikov about 13 years ago
I guess that we may do this but as Pavel said it's better to forget about this (and moreover do not touch all models and nevertheless obtain not reliable results) by means of more complex analysis may be with some help of aspectator.

That is a possible way but there is another aspect that we should keep in mind:
in current state of error trace visualizer Ctrl+F on ldv_ is an important instrument of error trace analysis (at least for me).

Doesn't ETV automatically expand all the model functions we instrument there?

ETV expands down to model functions and highlight them a little bit, but Ctrl+F is still more convenient tool then manual scrolling&looking on long list of error trace elements.
May be an optional button for highhighligting model functions can help to mitigate it.

Maybe simply more highlighted model functions would go? With a different background color, for instance?

Maybe, but if we more highlight all the interesting elements it would not help. So I would prefer to highlight it by user request only.

I changed the topic because it not related to following discussion

After all we decided to highlight model functions in error trace in the more visible way.
