--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
There has been no update on this request in over 7 years. Is it still relevant
(especially in light of comment #1)? If so, can you provide more details?
I.e., what warnings specifically would you like to treat as errors that
-Werror=warning-name doesn't let you do? Like so:
$ cat t.c && /build/gcc-git/gcc/xgcc -B /build/gcc-git/gcc -O0 -S -Wall
-Werror=int-conversion t.c
int f (void*);
void* g (void)
{
char *s = f (0);
f (123);
s = 345;
return 456;
}
t.c: In function ‘g’:
t.c:4:13: error: initialization makes pointer from integer without a cast
[-Werror=int-conversion]
char *s = f (0);
^
t.c:5:6: error: passing argument 1 of ‘f’ makes pointer from integer without a
cast [-Werror=int-conversion]
f (123);
^~~
t.c:1:5: note: expected ‘void *’ but argument is of type ‘int’
int f (void*);
^
t.c:6:5: error: assignment makes pointer from integer without a cast
[-Werror=int-conversion]
s = 345;
^
t.c:7:10: error: return makes pointer from integer without a cast
[-Werror=int-conversion]
return 456;
^~~
t.c:4:9: warning: variable ‘s’ set but not used [-Wunused-but-set-variable]
char *s = f (0);
^
cc1: some warnings being treated as errors
