Subject: [cocci] Avoiding duplicate elements in SmPL disjunctions?
Date: Sat, 8 Nov 2025 10:50:38 +0100	[thread overview]
Message-ID: <228c50a2-bb15-4abe-bef9-b0f9b95f6992@web.de> (raw)

Hello,

I tried the following script variant out for the semantic patch language.

@display@
statement s;
@@
*while (1)
    s


Questionable test result (according to the software combination “Coccinelle 1.3.0”):
Markus_Elfring@Sonne:…/Projekte/Coccinelle/janitor> /usr/bin/spatch --parse-cocci show_unlimited_while_loops.cocci
…
(
*while *(*1*) 
|
*while *(*1 *!= *0*) 
|
*while *(*1*) 
|
*while *(*0 *!= *1*) 
)s
…


An element of the generated SmPL disjunction got repeated somehow.
How do you think about to avoid such duplicate code?

Regards,
Markus
