3     * Generic 32-bit binary float operation. a0 = a1 op a2.
4     *
5     * For: add-fp, sub-fp, mul-fp, div-fp
6     *
7     * On entry:
8     *     a0 = target dalvik register address
9     *     a1 = op1 address
10     *     a2 = op2 address
11     *
12     * IMPORTANT: you may specify "chkzero" or "preinstr" but not both.
