PHP Bug Type: Compile Warning
Bug description: zend_operators.h generates discard qualifier compiler warning
Description:
------------
Zend/zend_operators.h: In function `void* zend_memrchr(const void*, int,
unsigned int)':
Zend/zend_operators.h:250: warning: cast from
const void*' to unsigned
char*' discards qualifiers from pointer target type
Zend/zend_operators.h:250: warning: cast from const void*' to unsigned
char*' discards qualifiers from pointer target type
In code snippet, line 250 refers to the two recasts of argument s.
Reproduce code:
---------------
static inline void *zend_memrchr(const void *s, int c, size_t n)
{
register unsigned char *e;
if (n <= 0) {
return NULL;
}
for (e = (unsigned char *)s + n - 1; e >= (unsigned char *)s; e--) {
if (*e == (unsigned char)c) {
return (void *)e;
}
}
return NULL;
}
Expected result:
----------------
No compiler warnings.
