Hello,
I know that the following SmPL script example gets accepted
by the Coccinelle software.
@display@
expression x, y;
@@
*y = ... *(x) ...
I have tried another tiny script variant out for the semantic patch language
(according to the software combination “Coccinelle 1.0.8-00131-g675b9670”).
@display@
expression action, x, y;
@@
(
*y = ... *(x) ...
|
*action(..., x, ...)
)
elfring@Sonne:~/Projekte/Coccinelle/janitor> spatch --parse-cocci show_pointer_dereferences3.cocci
init_defs_builtins: /usr/local/bin/../lib/coccinelle/standard.h
minus: parse error:
File "show_pointer_dereferences3.cocci", line 5, column 14, charpos = 54
around = '...',
whole content = *y = ... *(x) ...
Should such SmPL disjunctions work in the future?
Regards,
Markus

This is probably not what you think. It is an assignment of y to a
multiplication followed by some other code (the second ...).
