I would like to point another implementation detail out.
Another known function was also an update candidate.

This patch generation can work based on the following SmPL code combination.
“…
expression n, x;
…
- , (n) * \( sizeof(T) \| sizeof(*(x)) \)
…”
The asterisk should refer to a pointer expression within a sizeof operator.
I got informed that the semantic patch language would support such a restriction.
Thus I have tried out to specify the corresponding metavariables in this way.
“…
expression n;
expression* x;
…”
But the shown diff hunk is not regenerated by this SmPL script variant.
How should an array like “builtin_formats” (which is even defined in the same function)
be treated by the Coccinelle software in such use cases?
Regards,
Markus
