Hello.
I had problem in linking error with __float128 conversion functions. I
am using FreeBSD/amd64 -current and
test code is below.
#include <strings.h>
int
main(void)
{
__float128 a;
long double b;
bzero(&a, sizeof(__float128));
bzero(&b, sizeof(long double));
a = b;
b = a;
return (0);
}
When I build above code, I got linking error. Is this just unsupported
functions or something missing in header
or linking options? Error message is below.
