If anyone has any objections, please let me know. ------------------ From: Maciej W. Rozycki <macro@...tec.com> commit a9db101b735a9d49295326ae41f610f6da62b08c upstream. Complement commit fb6883e5809c ("MIPS: microMIPS: Support handling of delay slots.") and actually decode the regular MIPS JALX major instruction opcode, the handling of which has been added with the said commit for EPC calculation in `__compute_return_epc_for_insn'. Fixes: fb6883e5809c ("MIPS: microMIPS: Support handling of delay slots.") Signed-off-by: Maciej W.
