There are 2 bugs existing in __udiv_qrnnd_c:
1. remainder could not be counted correctly
__r1 and __r0 are not adding enough, so I use do..while to replace
former if
2. the case of overflow of __m are not considered
so I add a couple of lines to handle it
I found the bugs from Linux kernel,
for
t; : "(FAIL)");
printf(" %e / %e = %e\n", a.f, b.f, z.f);
}
int main()
{
union fu fa,fb,fe;
fa.u = 0xc0843fff;
fb.u = 0x80ff;
fe.u = 0x7f044000;
fdiv(fa,fb,fe);
}
