Hello!
Probably I'm doing something wrong, but I have some problems comparing a double
with NAN: The value is NAN, but the test fails. Probably I should use isnana().

int main()
{
double d = NAN;
assert(d == NAN);
return 0

Hi,
I ran into a couple of aliasing issues with a project I'm working on,
and have some questions.
The first is an issue with TOC-relative addresses on PowerPC. These are
symbolic addresses that are to be loaded from a fixed slot in the table
of contents, as addressed by the TOC pointer (r2). I
