From 434c9f2e3b4667859a705b48d53f23f5f629ecf1 Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Fri, 16 Jun 2017 00:06:19 +0100 Subject: [PATCH] MIPS: Actually decode JALX in `__compute_return_epc_for_insn' 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'.
