WebIn C << will do a shift left, and whether the shift instruction is printed as SAL or SHL depends on the compiler/disassembler. OTOH there are 2 versions of right shift because you can fill the bits that were shifted out with zero ( logical shift) or the high bit of the old value ( arithmetic shift).

Internally, it does this by subtracting them. A conditional jump instruction, like "je" (jump-if-equal), does a goto somewhere if the two values satisfy the right condition. For example, if the values are ... fixs or fixes
