L_sub

Subtraction of two 32-bit integer or fractional values, returning a 32-bit result.

Assumptions

OMR's SA bit was set to 1 at least three cycles before this code, that is, saturation on data ALU results enabled.

Prototype


  Word32 L_sub(Word32 src_dst, Word32 src2)

Example

long la = 0x40000000;  /* 0.5   */

long lb = 0xE0000000;  /* -0.25 */  

long result;



result = L_sub(la,lb);

// Expected value of result: 0x60000000 = 0.75
