This just means the test shouldn’t be run on 32-bit Intel.
Can you run this:
#include <stdint.h>
#include <stdio.h>
#include "issignaling_fallback.h"
int main (void) {
long double z;
z = __builtin_nansl("");
printf("%d\n", issignaling(z));
z = __builtin_nanl("");
printf("%d\n", issignaling(z));
}
compiled with -fsignaling-nans and the issignaling_fallback.h file from
libgfortran?
