| | | | | | | | | | | | | | | | | | | | | | | | For example, the following transformation: - sizeof(s)-1 + STRLEN(s) would replace sizeof by STRLEN even in the STRLEN macro definition itself, which generates following nonsensical patch: --- src/basic/macro.h +++ /tmp/cocci-output-8753-b50773-macro.h @@ -182,7 +182,7 @@ static inline unsigned long ALIGN_POWER2 * Contrary to strlen(), this is a constant expression. * @x: a string literal. */ -#define STRLEN(x) (sizeof(""x"") - 1) +#define STRLEN(x) (STRLEN("" x "")) /* * container_of - cast a member of a structure out to the containing structure Let's exclude the macro itself from the transformation to avoid this
* coccinelle: automatically rewrite memset() to zero() or memzero() where we canLennart Poettering2017-12-141-0/+30
