Hello, The following change specification gets accepted by the Coccinelle software.
@@ expression X; @@ -((X-1)&X) == 0 +powerof2(X) See also: https://github.com/DragonFlyBSD/DragonFlyBSD/blob/722c3b8b6376deab9407ff00b5e63018ab3aef0b/test/cocci/useful_macros.cocci#L53 I got into the development mood to try another code variant out for the semantic patch language. @adjustment@ expression X; @@ +powerof2( -(X-1)& X) - == 0 Unfortunately, the error message “unexpected close parenthesis in line 6” is reported then. Can an other change variation make sense finally?
