ammendment:
in the basic gcc-3_1-branch
there should be a warning for each of these scanf calls, but for the
last scanf( "%LX", ullp ) there is no warning.
should the test be changed or should there not be a warning ?
below is the code:
void
foo (long long ll, unsigned long long ull, long long *lln,
long long *llp, unsigned long long *ullp)
{
/* Test for accepting standard "long long" formats. */
printf ("%lld%lli%llo%llu%llx%llX%lln", ll, ll, ull, ull, ull, ull,
lln);
scanf ("%lld%lli%llo%llu%llx%llX%lln", llp, llp,
ullp, ullp, ullp, ullp, lln);
/* Use of "q" and "L" should still be warned about. */
printf ("%qd", ll); /* { dg-warning "C" "printf %qd" } */
printf ("%qi", ll); /* { dg-warning "C" "printf %qi" } */
printf ("%qo", ull); /* { dg-warning "C" "printf %qo" } */
printf ("%qu", ull); /* { dg-warning "C" "printf %qu" } */
printf ("%qx", ull); /* { dg-warning "C" "printf %qx" } */
printf ("%qX", ull); /* { dg-warning "C" "printf %qX" } */
printf ("%qn", lln); /* { dg-warning "C" "printf %qn" } */
printf ("%Ld", ll); /* { dg-warning "C" "printf %Ld" } */
printf ("%Li", ll); /* { dg-warning "C" "printf %Li" } */
printf ("%Lo", ull); /* { dg-warning "C" "printf %oL" } */
printf ("%Lu", ull); /* { dg-warning "C" "printf %Lu" } */
printf ("%Lx", ull); /* { dg-warning "C" "printf %Lx" } */
printf ("%LX", ull); /* { dg-warning "C" "printf %LX" } */
scanf ("%qd", llp); /* { dg-warning "C" "scanf %qd" } */
scanf ("%qi", llp); /* { dg-warning "C" "scanf %qi" } */
scanf ("%qo", ullp); /* { dg-warning "C" "scanf %qo" } */
scanf ("%qu", ullp); /* { dg-warning "C" "scanf %qu" } */
scanf ("%qx", ullp); /* { dg-warning "C" "scanf %qx" } */
scanf ("%qX", ullp); /* { dg-warning "C" "scanf %qX" } */
scanf ("%qn", lln); /* { dg-warning "C" "scanf %qn" } */
scanf ("%Ld", llp); /* { dg-warning "C" "scanf %Ld" } */
scanf ("%Li", llp); /* { dg-warning "C" "scanf %Li" } */
scanf ("%Lo", ullp); /* { dg-warning "C" "scanf %oL" } */
scanf ("%Lu", ullp); /* { dg-warning "C" "scanf %Lu" } */
scanf ("%Lx", ullp); /* { dg-warning "C" "scanf %Lx" } */
scanf ("%LX", ullp); /* { dg-warning "C" "scanf %LX" } */
