After try, modeless define needs multiple functions, and 'i386.c' needs
to know about them. e.g. let 'ix86_gen_tls_global_dynamic_64' point to
gen_tls_global_dynamic_64_di() or gen_tls_global_dynamic_64_si().
I guess, following this way, quite a few code in 'tilegx.c' will be
modified for it, or it will cause issue (still look for the original no
mode function name). e.g.
../../gcc-tile-new/gcc/config/tilegx/tilegx.c:2925:5: error: ‘CODE_FOR_insn_ld’ was not declared in this scope
{ CODE_FOR_insn_ld, NULL }, /* ld */
^
If what I said above is really correct, for me, we have to try to find
another ways to solve this issue (it is not worthy enough to modify
quite a few code only for avoiding the suggesting warnings).
Thanks.
