L_shr_r

Arithmetic shift of 32-bit value by a specified shift amount. If the shift count is positive, a right shift is performed. Otherwise, a left shift is performed. If a right shift is performed, then rounding performed on result. Saturation may occur during a left shift.

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_shr_r(Word32 lval2shft, Word16 s_shftamount)

Example

long l1 = 0x41111111;

short s2 = 1;

long result;



result = L_shr_r(l1,s2);

// Expected value of result: 0x20888889
