MIPS16/opcodes: Fix PC-relative operation delay-slot adjustment Complement commit dd8b7c222e0e ("MIPS: mips16e jalrc/jrc opcodes"), <https://sourceware.org/ml/binutils/2005-07/msg00349.html>, and stop the disassembler making a delay-slot adjustment for PC-relative operations following either MIPS16e compact jumps, or undefined RR/J(AL)R(C) encodings that have the `l' (link) and `ra' (source register is `ra') bits set both at a time. Adjust code description for accuracy. Add a suitable test case. opcodes/ * mips-dis.c (print_mips16_insn_arg): Avoid delay-slot adjustment for PC-relative operations following MIPS16e compact jumps or undefined RR/J(AL)R(C) encodings. binutils/ * testsuite/binutils-all/mips/mips16-pcrel.d: New test. * testsuite/binutils-all/mips/mips16-pcrel.s: New test source. * testsuite/binutils-all/mips/mips.exp: Run the new test.
