_SubSatInt

9/7/2007

This ARM DSP-enhanced operation performs a saturating subtract instruction. It subtracts the value in Rn from the value in Rm, and places the result in register Rd. This operation affects the sticky-overflow bit 'Q' if overflow occurs in the subtraction.


int _SubSatInt(
  int Arg1,
  int Arg2
);

Arg1

[in] The first term in the difference, the contents of Rm.

Arg2

[in] The second term in the difference, the contents of Rn.

The result of the binary arithmetic.

The compiler translates this intrinsic into the qsub assembly instruction.
