Many of the remaining x87-based asm implementations do not remove excess precision on return. This looks like a bug, but matches Glibc behavior. Moving such functions to C would either introduce removal of excess precision, or result in code that lies to the compiler by pretending that inline asm keeps values within precision of float/double, where in reality it might not.
