Subject: [cocci] Increasing awareness for short-circuit evaluation consequences by SmPL disjunctions?
Date: Wed, 5 Feb 2025 13:05:37 +0100	[thread overview]
Message-ID: <55fe2528-2405-4762-8e2c-f326810dc2ea@web.de> (raw)

Hello,

Disjunctions of the semantic patch language are using short-circuit evaluation.
It has got the consequence that the last element of the specified condition will
only be checked if all previous parts did not match. Such a technical detail
can lead to a recommended ordering of condition parts if you would like to care
for optimal run time characteristics of SmPL code.

The usage incidence might be unclear for involved case distinctions.
How do you think about to clarify possibilities any further for the reordering of
SmPL disjunction items?

Regards,
Markus
