The patch looks good to me.
I am wondering we could move gdb.trace/ftrace-insn-reloc.c to
gdb.arch/insn-reloc.c, because it is can be used for testing displaced
stepping as well. We can move gdb.trace/ftrace-insn-reloc.exp
to gdb.arch too. Any objections?
You can push it in in a few days if there are no objections on moving
them to gdb.arch directory.
