Re: [avr-gcc-list] [discussion] lpm support in avr-gcc

Hi Svein,

If that also applies to function arguments, it will
break the compiler optimization.

foo(const char *bar);

indicates, that foo won't change the contents of bar.

Would we have to rewrite stdlib.h then,
Like 'atoi(const char *)' to 'atoi(char *)'?

And what about string literals? Are they progmem by
default? If yes, can I write:

  const char eol[] = "\r\n";
  char *line;

  readln(line);
  prints("Hello ");
  prints(line);
  prints(eol);

With GCC I can use

  const char eol[] = PSTR("\r\n");
  char *line;

  readln(line);
  prints("Hello ");
  prints(line);
  prints_P(eol);
