JGE
Jump if Greater Than or Equal
JGE.U
Jump if Greater Than or Equal Unsigned
Description
If the contents of D[a] are greater than or equal to the contents of either D[b] (instruction format BRR) or const4
(instruction format BRC), then add the value specified by disp15, sign-extended and multiplied by 2, to the
contents of PC and jump to that address.
Operands are treated as signed (JGE) or unsigned (JGE.U), 32-bit integers. The const4 value is sign-extended
(JGE) or zero-extended (JGE.U).
JGED[a], const4, disp15 (BRC)
if (D[a] >= sign_ext(const4)) then PC = PC + sign_ext(disp15) * 2;
JGED[a], D[b], disp15 (BRR)
if (D[a] >= D[b]) then PC = PC + sign_ext(disp15) * 2;
JGE.UD[a], const4, disp15 (BRC)
if (D[a] >= zero_ext(const4)) then { // unsigned comparison
PC = PC + sign_ext(disp15) * 2;
}
JGE.UD[a], D[b], disp15 (BRR)
if (D[a] >= D[b]) then PC = PC + sign_ext(disp15) * 2; // unsigned comparison
