Yes, yes, sorry for confusion. What I actually tried to suggest is
something like the trivial patch below.
Then arm can do:
uprobe_opcode_t arch_uprobe_swbp_insn(struct arch_uprobe *auprobe)
{
return __opcode_to_mem_arm(auprobe->bpinsn);
}
No?
I notice there don't seem to be any alternative set_swbp functions
in the (rc6) kernel tree
Yes... I think we should simply make it "static". And set_orig_insn()
too.
Or. arm can actually reimplement set_swbp(). This doesn't mean the
duplication of write_opcode() code, we can simply export this helper.
That actually looks to me like the cleanest approach. I have changed
the static write_opcode() to a global uprobe_write_opcode(), and now
call it from an arm set_swbp().
Please do *not* make set_swbp() (and set_orig_insn()) static's. It
looks like we now have a use for at least one of them.
Thanks,
