Questions about defaults.h ASM_FORMAT_PRIVATE_NAME

["Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>]

The defaults.h copy of ASM_FORMAT_PRIVATE_NAME looks like this:

  do {									\
    int len = strlen (NAME);						\
    char *temp = (char *) alloca (len + 3);				\
    temp[0] = 'L';							\
    strcpy (&temp[1], (NAME));						\
    temp[len + 1] = '.';						\
    temp[len + 2] = 0;							\
    (OUTPUT) = (char *) alloca (strlen (NAME) + 11);			\
    ASM_GENERATE_INTERNAL_LABEL (OUTPUT, temp, LABELNO);		\
  } while (0)


1.  Aside from some obvious inefficiencies, I was wondering about the
    call to ASM_GENERATE_INTERNAL_LABEL.  Namely why is it used?  Most
    (all?) ports define their own version which simply does this:
    sprintf (BUF, "%s.%d", NAME, NUM).  I.e. without any '*' prefix.

2.  Given that it must return space allocated by alloca, there's no
    way to make this into a (target hook) function, right?  So the
    best hope would be to simply eliminate duplicate port specific
    copies (as long as I understand the use of GENERATE vs naked
    sprintf?)

The tm.texi documentation wasn't 100% clear (to me at least) in this
regard.  At least, I would have suspected that using GENERATE here
would be wrong and we're getting lucky because all ports define their
own copy of this macro. (?)
