> %f is correct for double.
Yes, the float was promoted to double via the ellipsis ... as I understand it
(default type promotion - I am sure you know a lot more about this than I do),
but the message should say 'float' like the following I thought?
The 'argument' is float, within the printf it arrives as a 'parameter' of type
double after the promotion before the call.
I guess what I am saying, is the message should state the type before the
promotion? Clang does it as I expect
I expected:
<source>:5:14: warning: format '%d' expects argument of type 'int', but
argument 2 has type 'float' [-Wformat=]
5 | printf("%d", i);
| ~^ ~
| | |
| int float
| %f
