In case of short jump the offset is stored in

WebThe jump is a far jump if the target address is in a different code segment. In this case, the assembler stores the code segment and the offset of the target address within that segment in the instruction. The table below summarizes all the addressing modes used with the unconditional jump instruction. WebJun 25, 2024 · 1 Answer.

WebMay 11, 2016 · Short jump's relative memory offset is a 1 signed byte which means the value range is between -128 and 127. 0x82 in this example is in fact treated as -126. We need to be very careful when inserting bytes. The tool also needs to detect if the instruction needs to be converted from short to far.

WebThis goes back into the bytecode and replaces the operand at the given location with the calculated jump offset. We call patchJump() right before we emit the next instruction that we want the jump to land on, so it uses the current bytecode count to determine how far to jump.
