Among these, it sets the -zero flag if the difference is zero (operands are equal). - -TEST sets the zero flag (ZF) when the result of the AND operation is zero. If -the two operands are equal, their bitwise AND is zero only when the operands -themselves are zero. TEST also sets the sign flag (SF) when the most -significant bit is set in the result, and the parity flag (PF) when the number -of set bits is even. - -JE (alias of JZ) tests the zero flag and jumps if it is set. This creates the -following equivalencies: - -test eax, eax -je <somewhere> ----> if (eax == 0) {} - -cmp eax, ebx -je <somewhere> ----> if (eax == ebx) {} |
