Bug ID: 78989
Summary: Missing -Waddress warning
Product: gcc
Version: unknown
Status: UNCONFIRMED
Keywords: diagnostic
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
Target Milestone: ---
Following test-case does not report warning:
$ cat /tmp/gimplify.ii
int
asan_poison_variables ()
{
return (asan_poison_variables &&
# 6 "gimplify.cpp" 3 4
__null
);
}
./xgcc -B. /tmp/gimplify.ii -Wall -c
[nothing]
While:
cat /tmp/gimplify.ii
int
asan_poison_variables ()
{
return (asan_poison_variables &&
__null
);
}
$ ./xgcc -B. /tmp/gimplify.ii -Wall -c
/tmp/gimplify.ii: In function ‘int asan_poison_variables()’:
/tmp/gimplify.ii:5:31: warning: the address of ‘int asan_poison_variables()’
will never be NULL [-Waddress]
__null
^~~~~~
It's somehow related to the location if *.ii file, but I don't know how.
Thanks
