Bug ID: 104289
Summary: -fdiagnostics-parseable-fixits doesn't always generate
fixit notes
Product: gcc
Version: 11.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: eric.pouech at orange dot fr
Target Milestone: ---
[eric]$ cat b2.c
#include <stdio.h>
#define foo(x...) printf(x);
int main(void)
{
long l = 0;
foo("this is a"
"long line: %d\n", l);
return 0;
}
[eric]$ LC_ALL=C gcc -Wall -fdiagnostics-parseable-fixits -c b2.c
b2.c: In function 'main':
b2.c:8:9: warning: format '%d' expects argument of type 'int', but argument 2
has type 'long int' [-Wformat=]
8 | foo("this is a"
| ^~~~~~~~~~~
9 | "long line: %d\n", l);
| ~
| |
| long int
b2.c:3:26: note: in definition of macro 'foo'
3 | #define foo(x...) printf(x);
| ^
I'm expecting a fixit note to be present.
Note: the same snipnet without the multi line string, or the macro work as
expected.
