           Summary: typo in diagnostic: refernced
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED

gcc/c-family/c-attribs.c says:
> "refernced symbol declared here"

That should be "referenced" instead.
A test to trigger this diagnostic is:

~~~c
/* { dg-do compile } */
/* { dg-options "-O2 -Wall" } */

void invalid_free(/* no prototype */); /* { dg-message "referenced" } */

void *invalid_malloc(void) __attribute__((
  malloc(invalid_free) /* { dg-warning "must take a pointer" } */
));
~~~

A test to trigger the closely related diagnostic is:

~~~c
/* { dg-do compile } */
/* { dg-options "-O2 -Wall" } */

void invalid_free(int); /* { dg-message "referenced" } */

void *invalid_malloc(void) __attribute__((
  malloc(invalid_free) /* { dg-warning "must take a pointer" } */
));
~~~=
