K&R style parameter lists and register banks/masks

Alexander Floh

hi, since ansi-c allows k&r style parameter lists which look something like this

int my_function(arg0, arg1)
  int arg0;
  char arg1;
{
  /* code */
}

i was wondering how the keil c166 compiler handles these in combination with register banks and masks.

a quick test showed that register banks seem not to work in combination with that declaration list, but register mask do.

it would be nice if someone could confirm my assumptions or correct them if they are wrong / point me to documentation where this is specified (i couldn't find anything about this in the manual)

thanks in advance,
alexander floh

    Why bother? There's quite exactly no valid reason at all to use that deprecated parameter list format, so it's completely irrelevant what consequences using it might have.

    thanks for the response,

    true, but I have to implement a parser which should have the same behaviour the keil parser has (at least as far as possible), therefore it would be great to know how the keil behaves in this special case. (especially since keil seems to handle the situations inconsitently, it allows a register mask + declaration list, but it doesn't allow a register bank + declaration list)
