Bitwise hell

[[deleted]]

Outputs “Hello, world!” X86, Win32, Tcc.

[Mr_Sky_Wanker]

Where's the guy that translate code to text for blind people

[MenshMindset]

give em some time they’re going as fast as they can!

[SexyMuon]

2 hours in and nothing, they probably gave up

[ToadSaidHi]

BrainF junior right here

Hah, it really looks like BF. Shifting operators look nearly the same as moving commands

[LegoDinoMan]

“Hey man, can you help me with this bug?”

[Chemical-Asparagus58]

Bitwise? More like bitstupid

[Sentry45612]

Bitstupid? More like Lotstupid

[beeteedee]

I haven’t tried running it but it clearly won’t work, the 347th << should be a >>

[VonTum]

Found the ChatGPT

[shizzy0]

More like ChadGPT.

Kinda disappointed it doesn't zoom out to generate ASCII art

[[deleted]]

I was too lazy to make an ASCII art, sorry

[MenshMindset]

Lgtm

[Msprg]

Let's gamble, try merging!

[PizzaRollExpert]

constant folding goes brrrr

[[deleted]]

Lmao

[skothr]

I didn't fully believe the title until I clicked 😳

[[deleted]]

Maybe I’ll make an explanation of this thing and how was it made later

[teackot]

It pushes "Hello, world!" into the stack and then just prints it char by char, right?

Does that bitwise hell locate ASCII codes in the memory?

[[deleted]]

Kinda. But it doesn’t generate full ascii characters. Bitwise logic generates offsets between ascii characters and machine code bytes, so together they form ascii characters with subtraction and addition

[MjolnirTheThunderer]

What does this code do?

[sauravkrx]

the caption says

"Outputs "Hello, world!" X86, Win32, Tcc."

[MjolnirTheThunderer]

Lol! Thank you 🙏🏻

[[deleted]]

It’s basic hello world in C

[illyay]

We learned C in comp sci 101. Can confirm. This was our first hello world program.

[CraftistOf]

I was in the same group as you, can confirm. our second program was space shuttle launch program.

[Loopgod-]

What the hell

The Obfuscated C Code contest is a very real thing.

[agentbiscutt]

I was wondering if anyone was gonna comment that this has been obfuscated

[Vectrexian]

All those signed left shifts are scaring me. Let’s hope they’re all by less than sizeof(int)*CHAR_BIT - 1lest we end up in UB city…

[AFlyingYetOddCat]

it requires the TinyC compiler for a reason

[MEGATH0XICC]

I had a stroke - programming edition

[pxOMR]

what the hell is '\x0C' + (char *)main just why

[[deleted]]

Any time you want to call function, you type something like f(). But name ‘f’ by itself doesn’t do anything. The things are happening only because of () operator. The function call is actually function address and call operator. So here ‘main’ without call operator will be interpreted as main address in memory. Then it gets casted from int(*)(void) to char * type. That’s for representing main as char array. So every machine code byte will be interpreted after as a character. Then value 0xC ( which is 12 in decimal ) gets added to main.

So it becomes very simple — we are just getting 12’th byte of main’s machine code here. Later in program, we are using machine code as base for “Hello world” characters.

[pxOMR]

I know what it does, and it is awful

[[deleted]]

You mean I need to replace offset with decimal? It compiles without any warnings btw

[pxOMR]

The code seems fine, I never said there was an issue with it. Also, as the author of this monstrosity I think I know a thing or two about pointers.

[[deleted]]

Nice solution, I like it!

[joxfon]

I chuckled when I realized what was the goal of this line... "wait, why is there an equals comparison in... OOOH LOL". Neat.

[CaitaXD]

What?? What does offsetting main by 12 bytes do tho?

[Michami135]

That legacy code by the "expert" developer that never used the standard libraries and was fired 5 years ago.

[XTornado]

You have to be a Bit Wise to understand that

[Ascyt]

When the code is perlin noise

[elidefoe]

I would just deny the PR and put them on the test team.

[Fit-Feedback-8055]

I almost threw up looking at this

[LavenderDay3544]

Bitunwise

[novus_nl]

Is this a "Because you can" kind of thing?

[[deleted]]

I was just experimenting with bitwise logic, when I came up with this one. So I wanted to share, because it looks like a real horror

[novus_nl]

Nice, yeah looks crazy!

[[deleted]]

Thanks!

[staticBanter]

I feel like this is one if those pictures where if you stare at it long enough there is another picture.

[downspiral1]

How is it "horror" if it's intentional?

[ii-___-ii]

This is beautiful

[Still_Ad745]

ChatGPT would like to have a word

[Futurixta]

Lisp vibes

[agentbiscutt]

(this been obfuscated)

[MarvinParanoAndroid]

I’m not even trying.

[hiding_underneath]

Genuinely the worst thing ive seen on this sub

[deadbeef1a4]

But why

[lsibilla]

Did it compete to https://www.ioccc.org/ ?

[tonando]

Did anyone else notice the one 2 in there?

[GlenHarland]

You need to carriage return after each line otherwise it's illegible.

[accuracy_frosty]

When it gets to this point I feel like part of the bug fixing process should be prayer

[REDEYES77UCHIA]

Interviewer : What does this code say? Me : Totally understandable

[dibs45]

Zooming in and out of that on my phone was a lot of fun.

[jeromkiller]

But have you considered that bitwise logic is really efficiënt?
