Summary: -Wdouble-promotion warns for promotion by varargs
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
The following program gives a warning about double promotion:
#include <stdio.h>
void
p()
{
float q = 5;
printf("%g\n", q);
}
Since, there's not much that can be done to fix this situation it's probably
not worth warning about. Alternatively, a switch could be added to avoid the
warning spam.
