--- Comment #13 from Martin Sebor <msebor at gcc dot gnu.org> ---
Yes, thanks Eric, the request has been implemented in GCC 9 and can be resolved
as fixed.

$ cat pr63886.c && gcc -S -Wall -Wextra pr63886.c

extern void g(int);

void f( float qw)
{
        int n = abs(qw);        

        g(n);
}
pr63886.c: In function ‘f’:
