+       * config/tc-i386.c (output_branch): Handle BND prefix the same
+       way as other prefixes. Emit it last before REX.
+       (output_jump): Emit BND before REX.
+       (output_interseg_jump): Don't emit REX.
+       * testsuite/gas/i386/x86-64-branch-2.s,
+       testsuite/gas/i386/x86-64-branch-3.s,

+       testsuite/gas/i386/x86-64-mpx-branch-2.s: Add REX.W cases.
+       * testsuite/gas/i386/x86-64-mpx-branch-2.d: Match output against
+       x86-64-mpx-branch-1.d.
+       * testsuite/gas/i386/x86-64-branch-2.d,

+       * config/tc-i386.c (flip_code16): New.
+       (output_branch, output_jump): Use it.
+       (i386_displacement): Restrict template set to just direct
+       branches when handling a respective operand. Don't set Disp16
+       when in Intel64 mode and there's a respective template.
+       * testsuite/gas/i386/i386.exp: Convert x86-64-branch-3 from list
+       to dump test. Drop its XFail again.

+       * testsuite/gas/i386/x86-64-branch-3.l: Delete.
