WebApr 11, 2024 · GCC could detect this and warn, which would be good, but I wouldn't expect them to add compiler back-end support for x86's ability to do misaligned atomic accesses (with a lock prefix for an RMW instruction, or xchg) at the cost of extremely bad performance which locks the bus and thus slows down other cores. That's a disaster on … WebJump instructions are always optimized to use the smallest possible displacements. This is accomplished by using byte (8-bit) displacement jumps whenever the target is sufficiently close. If a byte displacement is insufficient a long (32-bit) displacement is used.
