Subject: [Cocci] Checking parsing difficulties around SmPL when constraints
Date: Wed, 11 Sep 2019 09:42:19 +0200
Message-ID: <> (raw)


A specific test case is available for the semantic patch language.

Can the following code variant work also under other circumstances?

expression x;
position p;

expression action, x, y, z;
position p != extra.p;
statement es;
*if (!x)
    (<+... when != (x) = y
*   *(x@p)
|   action(z,
*          x@p
           , ...)

elfring@Sonne:~/Projekte/Coccinelle/janitor> spatch --parse-cocci show_null_pointer_usage13.cocci
minus: parse error:
  File "show_null_pointer_usage13.cocci", line 16, column 11, charpos = 178
  around = 'when',
  whole content =     (<+... when != (x) = y
