GCC now supports the spaceship operator (<=> in C++) for the LoongArch architecture. This addition helps optimize nested ternary operations that produce -1, 0, or 1 by translating them into slt[u]-slt[u]-sub instructions. This optimization can improve code efficiency for comparisons and conditional assignments.
