So, please send new patches as a new thread. This makes it much easier
to handle. If you want to reply to something in the old thread just do
it there, but send the new patch not as a reply.

Just "New." or "New flag." or similar?

The documentation says
Return true to generate ADDR_DIF_VEC table or false to generate
ADDR_VEC table for jumps in case of -fPIC.
but you can just leave out that last line completely.

It now is
@tablejump<mode>_nospec
so this code will become something like
if (rs6000_relative_jumptables)
jump = gen_tablejumpsi_nospec (Pmode, operands[0], operands[1], ccreg);
else
jump = gen_tablejump_absolute_nospec (Pmode, operands[0], operands[1],
ccreg);
emit_jump_insn (jump);
Okay for trunk with those changes. Thank you!
