Do you really need to use regular expressions in all of these cases? If
you don't need to use regular expressions, then it is better to avoid
them. Normally, if you have some function names in your semantic patch,
and they are essential for the semantic patch to apply, Coccinelle will be
applied to only files that contain these function names. With regular
expressions, it does not do this optimization.
If you want to see what it is filtering on, you can run spatch
-parse_cocci file.cocci, and the list of required words appears at the
end of the output.

Btw.
please note that calloc and realloc have different number and type of arguments.
I've created something like that for them:
@@
type T;
identifier malloc =~ "malloc$";
T *x;
@@
malloc(
- x
+ *(x)
)
@@
type T2, T3;
identifier calloc =~ "calloc$";
T2 *y;
T3 *z;
@@
calloc(
- y
+ *(y)
,
- z
+ *(z)
)
@@
type T4;
identifier realloc =~ "realloc$";
T4 *w;
@@
realloc( ... ,
- w
+ *(w)
)
I guess it might be simplified, but that's enough for my purposes.
Best regards,
Robert
