[PATCH v0 0/4] Emit fewer relocations for linker relaxation

mengqinggang (4):
  LoongArch: Fix the size of tls desc relocations
  LoongArch: Do not emit relocation if addsy and subsy are in the same
    frag
  LoongArch: Emit fewer relocations for label subtraction
  LoongArch: Emit alignment relocations after relaxed instructions
