-mno-ieee-fp
Enables improved floating-point consistency. Floating-point operations are not reordered and the result of each floating-point operation is stored in the target variable rather than being kept in the floating- point processor for use in a subsequent calculation. This is the same as specifying -fltconsistency or -mp.
The default, -mno-ieee-fp, provides better accuracy and run-time per- formance at the expense of less consistent floating-point results.
