/* There is no test for "fnegs" because the compiler will use an
integer operation instead to implement this operation. Adding
complexity to the operand (e.g., "-(f1 + f2)") doesn't change the
situation, as the compiler still wants the result in an integer
register before writing it back to memory. If we used an ABI that
required passing floating-point values in VFP registers that
would likely persuade the compiler to keep the value in the VFP
registers. */
