It doesn't use them. >Assuming no and no, do you understand why the IEEE754-expected 53 bits >is found on amd64? Is that just happenstance of how the test is >compiled? i386 uses 387 math, and that has 80bit registers. But in memory it's reduced to 64bit. That's what confuses paranoia. amd64 uses sse math with 64bit registers.
