Add reloc_unsign_bits() to fix others sop_pop relocs overflow check. Then add over/underflow tests for relocs B*, SOP_POP* and PCREL20_S2. bfd/ChangeLog: * bfd/elfxx-loongarch.c: Add reloc_unsign_bits(). ld/ChangeLog: * ld/testsuite/ld-loongarch-elf/ld-loongarch-elf.exp: Add tests. * ld/testsuite/ld-loongarch-elf/abi1_max_imm.dd: New test. * ld/testsuite/ld-loongarch-elf/abi1_max_imm.s: New test. * ld/testsuite/ld-loongarch-elf/abi1_sops.s: New test. * ld/testsuite/ld-loongarch-elf/abi2_max_imm.s: New test. * ld/testsuite/ld-loongarch-elf/abi2_overflows.s: New test. * ld/testsuite/ld-loongarch-elf/max_imm_b16.d: New test. * ld/testsuite/ld-loongarch-elf/max_imm_b21.d: New test. * ld/testsuite/ld-loongarch-elf/max_imm_b26.d: New test. * ld/testsuite/ld-loongarch-elf/max_imm_pcrel20.d: New test. * ld/testsuite/ld-loongarch-elf/overflow_b16.d: New test. * ld/testsuite/ld-loongarch-elf/overflow_b21.d: New test. * ld/testsuite/ld-loongarch-elf/overflow_b26.d: New test. * ld/testsuite/ld-loongarch-elf/overflow_pcrel20.d: New test. * ld/testsuite/ld-loongarch-elf/overflow_s_0_10_10_16_s2.d: New test. * ld/testsuite/ld-loongarch-elf/overflow_s_0_5_10_16_s2.d: New test. * ld/testsuite/ld-loongarch-elf/overflow_s_10_12.d: New test. * ld/testsuite/ld-loongarch-elf/overflow_s_10_16.d: New test. * ld/testsuite/ld-loongarch-elf/overflow_s_10_16_s2.d: New test. * ld/testsuite/ld-loongarch-elf/overflow_s_10_5.d: New test. * ld/testsuite/ld-loongarch-elf/overflow_s_5_20.d: New test. * ld/testsuite/ld-loongarch-elf/overflow_u.d: New test. * ld/testsuite/ld-loongarch-elf/overflow_u_10_12.d: New test. * ld/testsuite/ld-loongarch-elf/underflow_b16.d: New test. * ld/testsuite/ld-loongarch-elf/underflow_b21.d: New test. * ld/testsuite/ld-loongarch-elf/underflow_b26.d: New test. * ld/testsuite/ld-loongarch-elf/underflow_pcrel20.d: New test. * ld/testsuite/ld-loongarch-elf/underflow_s_0_10_10_16_s2.d: New test. * ld/testsuite/ld-loongarch-elf/underflow_s_0_5_10_16_s2.d: New test. * ld/testsuite/ld-loongarch-elf/underflow_s_10_12.d: New test. * ld/testsuite/ld-loongarch-elf/underflow_s_10_16.d: New test. * ld/testsuite/ld-loongarch-elf/underflow_s_10_16_s2.d: New test. * ld/testsuite/ld-loongarch-elf/underflow_s_10_5.d: New test. * ld/testsuite/ld-loongarch-elf/underflow_s_5_20.d: New test.
