Instructions comparing register values

Variants

GtA(NumTypeRegAReg32Reg32)

Compares value of two registers setting st0 to true if the first parameter is greater (and not equal) than the second one. Ignores first argument if R register is used.

GtR(RegRReg16RegRReg32)

Compares value of two registers setting st0 to true if the first parameter is greater (and not equal) than the second one. Treats both values as unsigned integers

LtA(NumTypeRegAReg32Reg32)

Compares value of two registers setting st0 to true if the first parameter is smaller (and not equal) than the second one. Ignores first argument if R register is used.

LtR(RegRReg16RegRReg32)

Compares value of two registers setting st0 to true if the first parameter is smaller (and not equal) than the second one. Treats both values as unsigned integers

EqA(RegAReg32RegAReg32)

Checks equality of value in two arithmetic (A) registers putting result into st0

EqR(RegRReg32RegRReg32)

Checks equality of value in two non-arithmetic (R) registers putting result into st0

Len(RegAReg32)

Measures bit length of a value in one of the registers putting result to a16[0]. If the register is in uninitialized state sets a16[0] to be uninitialized as well.

Cnt(RegAReg32)

Counts number of 1 bits in register putting result to a16[0] register. If the register is in uninitialized state sets a16[0] to be uninitialized as well.

St2A

Assigns value of a8[0] register to st0.

A2St

st0 value of st0 register to the result of a8[0] != 0. If the value is not set, assigns st0 false
