Description

Unused variable is not a problem itself, but its type is not declared (see Bug #7244). However removing such difficult variables may really helps.
Linux 4.5-rc7, drivers/net/wireless/ath/wil6210/wil6210.ko, EMG options:
"direct control function calls": false,
"omit all states": true,
"nested automata": true
Note, with the opposite options EMG generates the correct model.

I have not investigated reasons of why unused variables are generated, but recent improvements in EMG (emg-improvements branch) allows to check referred driver drivers/net/wireless/ath/wil6210/wil6210.ko now if it is important for you Pavel.

By the way any problems with scope is better to report as an additional issues or add them to the issue #7244 directly with increasing a priority if necessary.

  • Status changed from New to Resolved

I removed some usused variables recently in both translators. Moreover, the bug is relevant to the translator which is not used by default. Implemented in 8066-abstract-translator.
