c-ts-mode cannot fontify the following code:

ifsubmitbufl (tp)
{
  register	*kb1 = tp;
  extern	 tbase, i_len;
  register	 l = len;

again:
  
  highprio (); /* tbase is used by protoureg */
  iomap (&UBR, tbase += UBR_SIZ);
  UBR->addr_l = kb1;
  UBR->addr_m = kb1 >> 010;
  UBR->mode_l = 07777 &~ UBR_INST;
  UBR->mode_m = 0;
  UBR->long_l = l;
  UBR->long_m = l >> 010;

  iounmap ();
  tally_iostat (tbase);
  iospoke (UBR, P_LOCK);
  resetprio ();

  SWITCH (S_WAIT|S_HIGH|S_IMMED, 0700, again); /* this returns to
						  BR->senv[0], except
						  if CL_HI */
}

here, ifsubmitbufl, tbase, l and again are fontified as types.  They are
fontified correctly by CC Mode, as three identifiers and one label.

Trying to indent after "again:" results in text being indented to column
0.

Thanks, I fixe the label=E2=80=99s face. As for ifsubmitbufl, tbase, and =

Seems to work fine here. I don=E2=80=99t see anything I changed recently =
that could affect this, either.

Thanks.

Well, that code is 100% valid C.  "*kb1, tbase, i_len, l" are implicitly
int (which on that machine is 16 bits wide), and so is the value of
"ifsubmitbufl" and "tp".

Would someone try that?

Sorry, I think I meant "before".  Place point after "l =3D len;", then
press RET.

We should report these cases as bugs though, right?

IOW, I'm thinking that, going forward, perhaps in these cases it makes
sense for us to close bugs once there is a corresponding bug reported
against the relevant treesitter grammar.

It's K&R C, which is used very rarely these days, and it sounds like the
next version of GCC will reject it, since C2x makes it invalid.

So I see no catastrophe that c-ts-mode doesn't support this.  You can always
opt not to use c-ts-mode if you need this style supported.  Of course, if
tree-sitter's parser is updated to add such support, we'll all be happier.
