Fix stdio-common tests for GCC 12 -Waddress
|
||
|
|
|
||
|
|
My glibc bot shows failures building the testsuite with GCC mainline
|
||
|
|
across all architectures:
|
||
|
|
|
||
|
|
tst-vfprintf-width-prec.c: In function 'do_test':
|
||
|
|
tst-vfprintf-width-prec.c:90:16: error: the comparison will always evaluate as 'false' for the address of 'result' will never be NULL [-Werror=address]
|
||
|
|
90 | if (result == NULL)
|
||
|
|
| ^~
|
||
|
|
tst-vfprintf-width-prec.c:89:13: note: 'result' declared here
|
||
|
|
89 | wchar_t result[100];
|
||
|
|
| ^~~~~~
|
||
|
|
|
||
|
|
This is clearly a correct warning; the comparison against NULL is
|
||
|
|
clearly a cut-and-paste mistake from an earlier case in the test that
|
||
|
|
does use calloc. Thus, remove the unnecessary check for NULL shown up
|
||
|
|
by the warning.
|
||
|
|
|
||
|
|
Similarly, two other tests have bogus comparisons against NULL; remove
|
||
|
|
those as well:
|
||
|
|
|
||
|
|
scanf14a.c:95:13: error: the comparison will always evaluate as 'false' for the address of 'fname' will never be NULL [-Werror=address]
|
||
|
|
95 | if (fname == NULL)
|
||
|
|
| ^~
|
||
|
|
scanf14a.c:93:8: note: 'fname' declared here
|
||
|
|
93 | char fname[strlen (tmpdir) + sizeof "/tst-scanf14.XXXXXX"];
|
||
|
|
| ^~~~~
|
||
|
|
|

|
|
scanf16a.c:125:13: error: the comparison will always evaluate as 'false' for the address of 'fname' will never be NULL [-Werror=address]
|
||
|
|
125 | if (fname == NULL)

Tested with build-many-glibcs.py (GCC mainline) for aarch64-linux-gnu.
