	         address of the corresponding int).

	         My guess is that this correction, as opposed to

	         for PCC on most machines), is the right thing to do

	         the sparc problem doesn't come up because the calling
	         function has to zero the top bytes (not knowing
	         whether the called function wants an int or a short),
	         so there is little practical difference between an
	         int and a short (except perhaps what happens when the

	         Hacked for SunOS 4.1 by gnu@cygnus.com.  In 4.1, the
	         compiler actually produces the correct address (we
	         don't need to fix it up).  I made this code adapt so
	         that it will offset the symbol if it was pointing at
	         an int-aligned location and not otherwise.  This way
	         you can use the same gdb for 4.0.x and 4.1 systems.

	         If the parameter is shorter than an int, and is
	         integral (e.g. char, short, or unsigned equivalent),
	         and is claimed to be passed on an integer boundary,
	         don't believe it!  Offset the parameter's address to

/* Skip rest of this symbol and return an error type.

   General notes on error recovery:  error_type always skips to the
   end of the symbol (modulo cretinous dbx symbol name continuation).
   Thus code like this:

   if (*(*pp)++ != ';')
   return error_type (pp, objfile);

   is wrong because if *pp starts out pointing at '\0' (typically as the
   result of an earlier error), it will be incremented to point to the
   start of the next symbol, which might produce strange results, at least
   if you run off the end of the string table.  Instead use

   if (**pp != ';')
   return error_type (pp, objfile);
   ++*pp;

   or

   if (**pp != ';')
   foo = error_type (pp, objfile);
   else
   ++*pp;

   And in case it isn't obvious, the point of all this hair is so the compiler
   can define new types and new syntaxes, and old versions of the
   debugger will be able to read the new symbol tables.  */
