From 55af478400524cba7994e353fd9a98ef1543df2f Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Fri, 9 Dec 2016 22:27:00 +0000 Subject: [PATCH] MIPS16/opcodes: Reformat raw EXTEND and undecoded output Use a tab rather than a space to separate `extend' and its uninterpreted argument output, like with regular instructions. Separate hexadecimal halves of undecoded extended instructions output with a space instead of presenting them concatenated. opcodes/ * mips-dis.c (print_insn_mips16): Use a tab rather than a space to separate `extend' and its uninterpreted argument output.
