Okay, I can confirm that the test suite works after adding -mieee when
building. Instead of just closing this bug as user error (since
-mieee is set by default in Debian's gcc packages, just not in
gcc-snapshot), I think it makes sense to add -mieee on Alpha in
upstream since this affects all Alpha systems.
For the record, the code that produces the floating point exception
without -mieee is
else if (do_scale) {
dvalue = icvp->scale * dvalue + icvp->offset;
}
in value_conversion.c.
Here's a reference to -mieee:
