Would you find the test result easier to clarify for the following
SmPL script example?
@display1@
expression action, e;
position p;
statement is, es;
@@
*e = action(...);
if@p (<+... e ...+>)
is
else
es
@display2@
expression check;
position display1.p;
statement display1.is, display1.es;
@@
*if@p (check)
is
else
es
elfring@Sonne:~/Projekte/Coccinelle/janitor> spatch --parse-cocci show_condition_checks_after_function_calls2.cocci
…
warning: iso drop_else does not match the code below on line 17
if@p (check) iselse es
…
Will any software improvements become interesting for such an use case?
Regards,
Markus
