Guess what ABI you need to use to call your operating system functions that
take floating-point arguments on x86-64? Hmm, you guess right: You put them
in SSE registers. And you cannot copy directly between SSE and x87 registers
(you need to go through memory). That is called "deprecated by an operating
system".
And maybe you ought to look up the word "deprecated" in the dictionary. It
is *not* a synonym for "deny"...
