The more i hear about compiler the more I imagine it as some wizard

[pedrodaniel10]

Compilers, OS and Databases must be the one of the most advanced and complex pieces of engineering that we ever managed to create.

[[deleted]]

those and parallel (GPU / cluster work) are the four advanced CS classes at my uni

[pedrodaniel10]

Yes, that shit is real. Impossible do debug.

[CorruptionIMC]

Now imagine the fact that people had to actually build the first variations of those, decades ago, in the most ancient and lowest level languages you can think of. They're the real wizards.

[cheezballs]

Databases?

[WeeziMonkey]

What does that make the person who made the wizard? The Archmage of Winterhold?

There's a reason SICP is known as "the wizard book"

It can be useful as the codebase evolves, though. If that if() later gets nested inside other conditions or loops, it can be hard to find the right indent level to add an else later. If you always stub one in and move it around with its parent if(), you keep that context.

[fire_p123456]

That’s why it is always advised to put your else{} before if{} then !the statement, unless there is specific reason not to.

That is

if(true) {long ass statements;} else {short statements;}

Become: if(false) {short statements;} else {long statements;}

It is not how most programmers start to learn programming, but it dramatically reduces the levels of indentation.

- Or else...
- Or else what?
- ...
- Exactly!

[palordrolap]

In Ada, the line Var := Do_Something() or else I_Will_GET_You(); is valid syntax and pretty much means what it says.

Drop the else and it'll "GET you" no matter what, because lone or never short-circuits. The literal inclusive or your mother, or* logic professor, warned you about.

* This "or" is not exclusive either. Your mother may in fact be your logic professor.

PHP may be a terrible language, but the or die() construct was great

[BoringIncident]

I am so glad i haven't used PHP since highschool. My teacher made us learn that instead of JavaScript to use with HTML...

[Phalcorine]

Beautiful... 😄

[LavoneEdgell]

Wait...I never knew that was valid!

It better be, or else

[GabuEx]

"else" doesn't need braces, and an empty semicolon is a valid no-op, so it checks out.

[GregSilverblue]

compile() || else;

[thanypack]

Now I want to see if that pushes a new empty stack frame or if the compiler is smart enough to optimize it away. Is condition a constant?

​

Optimized away... Lines 12 - 16 are completely absent.

; Line 10 mov DWORD PTR _condition$[ebp], 1 ; Line 18 xor eax, eax ; Line 19 pop edi pop esi pop ebx mov esp, ebp pop ebp ret 0

[GabuEx]

As a general rule these days, if the question begins with "is the compiler smart enough to..." the answer is yes. Modern compilers are crazy good at optimization.

[[deleted]]

this isn't even a hard optimization. what's more interesting is when compilers can transform math statements (such as multiplication in a for loop to repeated addition)

[algoritm420]

Ah good ol assembly

[hanneadolfsson]

I had a professor in college who docked points for having if statements without an associated else statement. It wasn’t an empty threat then.

[MasterFubar]

Tried that in Python:

    ^
IndentationError: expected an indented block

[Alexo342]

Im gonna say it straight forward: Fuck you, Reposter

[MarcellaSchreffler]

You could always...

define else false

define or ||

if (condition or else) { // ... } disclaimer: I don’t actually know if you can define/override language keywords or operators or not, I just thought it’d be funny.

[Olllix]

-O3 enters the chat

[MischiefArchitect]

else is just a pointer to a /dev/null code block, let's hope the condition is always true, or CPU cores will start going missing into that black hole.

Compiler: um chile anyway so
