[GBDK] GAMEBOY [C]

Name: !MILKRIBS4k 2009-06-16 17:13

Anyone on here use the gameboy c compiler gbdk? http://gbdk.sourceforge.net/ There doesn't seem to be much documentation on it! Most of the code I find on google is designed for an older version of the compiler! How would I go about displaying a simple sprite! Someone help MILKRIBS4k!

This is open-source: write the documentation instead of bitching about the lack of it.

just buy a gameboy advance for $10 and use gcc.

MILKRIBS, it seems that C is your first codan (no offence), so here are some beginner tips!

1. Use fprintf (``fast printf'') instead of printf.
2. ++i is faster than both i++ and i = i + 1. I won't get into detail why, because it goes down to ASM.
3. void main(void) is faster than int main(void) or int main(int, char **) since no value needs to be returned to the OS. It's also safer (no errors) and more portable.
4. Swapping with exclusive-or (a^=b^=a^=b swaps a and b) is faster than using a temporary. This works for all types (including structures), but not on all compilers. Some compilers may also give you a harmless warning.
5.Avoid indentation, the whitespace makes the program bigger. It also makes it slower, because the compiler has to remove all whitespace anyway before parsing.
6. Static storage duration objects are faster than automatic storage duration objects because the CPU doesn't have to set aside storage on the stack every time a function is called. Make your loop indexes global so that you can use them everywhere:
    int i;
    void func(void) { for (i = 0; i < 10; i++) ; /* ... */ }
    void func2(void) { for (i = 0; i < 20; i++) ; /* ... */ }
    /* ... */
7. Compilers often give more memory to arrays than you asked for. Here's how to check how big an array actually is (memset returns a null pointer if the size you passed to it is bigger than the size of the array you passed to it):
    int arr[256];
    size_t realsize;
    for (realsize = 0; realsize <= SIZE_MAX; ++realsize)
            if (!memset(arr, 0, realsize)) break;
    /* now you know that arr actually has realsize / sizeof (int) elements */
If you combine this with #6, your program will be faster in the long run (but this usually doesn't work for short programs).

Where did I claim that you are an anus? That's retarded.
Also read K&R before you try to do *anything* with C. It's the most natural thing to do. I've given you the most useful excerpts from the book, but no, you must enter with your bullshit and claim that you're smarter than Dennis Motherfucking Ritchie. Good luck in programming with that attitude, faggot, at least have some humility, because there are people smarter than you out there. Like, you know, the dude that designed the fucking language you use. Go on, try to logically show that *any* of these points is wrong, I'll be more than happy to disprove whatever nonsensical bullshit you utter.
Finally, I have not been in /b/ for two years, but seeing your attitude, I guess it's a place more suitable for you rather than me to go to. You go back to /b/, please, and come back when you've learned your place. And learned to fucking type, because ``plz'' is not a word in any language known to man.

Stuff like 5. makes no sense!
Let's just look at an example;

[~] echo 'I can ensure you I an no anus!' > milkribs1
[~] echo 'I can ensure you I an no anus!                 ' > milkribs2
[~] du -b milkribs1 milkribs2
31      milkribs1
48      milkribs2
Oh no, the second file, with superfluous whitespace, is bigger! By 17 bytes, which looks like the number of added trailing spaces.
Now let's look at some actual code.


[~] cat milk
{
  int i, j;

  for(i = 0; i < BOARD_ROW; i++)
    for(j = 0; j < BOARD_COL; j++)
    {
      move(i, j);
      addch(board[i][j]);
    }
  move(row, col);
}
[~] cat milk | sed -s 's/ //g' > milk2
[~] cat milk2
{
inti,j;

for(i=0;i<BOARD_ROW;i++)
for(j=0;j<BOARD_COL;j++)
{
move(i,j);
addch(board[i][j]);
}
move(row,col);
}
[~] du -b milk milk2
159     milk
113     milk2
[~]

Did I just make the file ~75% of its original size?

Also, about the speed; the compiler has to strip down the input file to pure code. Whitespace is not pure code, it is discarded before compiling the file. There is no whitespace in pure C. And the more whitespace there is, the longer will the discarding take. Granted, it won't make a difference in a 100-LOC file, but when you're writing a big project, it matters. It's about 20 seconds additional compile time for a 5-kLOC program (here, you just have to believe me, because I no longer have the source file; I don't keep four-year old stuff on my machine. But it makes sense, doesn't it?)

Seriously, are you trolling me?

Name: Anonymous 2009-06-17 14:01

Again, whoops, there has to be some whitespace, namely between type and declared variables. So that's one more byte in the stripped code. But the point still stands.

I've argued against a number of these in the past.
To make this quick,
4. Swapping with exclusive-or (a^=b^=a^=b swaps a and b) is faster than using a temporary. This works for all types (including structures), but not on all compilers. Some compilers may also give you a harmless warning.
Reasons for avoidance in practice
Most modern compilers can optimize away the temporary variable in the naive swap, in which case the naive swap uses the same amount of memory and the same number of registers as the XOR swap and is at least as fast, and often faster. As a general rule, you should never use the XOR swap unless you know for a fact that the naive swap will not suit your application (which is very rare in this day and age). The XOR swap is also much less readable, and can be completely opaque to anyone who isn't already familiar with the technique.1
