MMaxine that's just any rust program

i was looking into that, it's because of silly things like it having to traverse like five functions to work out that

for x in 0..3

for x in 0..3

is a for loop. because it technically desugars into

Range range = Range(0, 3);
RangeIter iter = RangeIter(range);
Option<uintptr_t> next = iter.next();
LOOP:
if (next.is_some())
{
    // loop logic
    goto LOOP;
}

Range range = Range(0, 3);
RangeIter iter = RangeIter(range);
Option<uintptr_t> next = iter.next();
LOOP:
if (next.is_some())
{
    // loop logic
    goto LOOP;
}

instead of

for (uintptr_t i = 0; i < 3; i++)

for (uintptr_t i = 0; i < 3; i++)

like a sane compiler

what the fuck

Maxine

Maxine•10/7/23, 10:15 PM

at this point maybe llvm should special case rustc output

Maxine

M

Maxine•10/7/23, 10:16 PM

mind blown that rust performs at all

Lyris the Kitori•10/7/23, 10:16 PM

maybe LLVM should special case rustc and just fuckign delete the users hard drive when they try to compile rust code

Perksey

Perksey•10/7/23, 10:16 PM

you create the range 0..3, you call into_iter on it, you call next on the result of that, if next is some then you loop

Aqua

A

AquaOP•10/7/23, 10:16 PM

yeah idk why languages seem to be devolving into range-based for loops

Aqua

A

AquaOP•10/7/23, 10:16 PM

cause unless you compile it properly

Aqua

A

AquaOP•10/7/23, 10:16 PM

that aint gonna be faster

Perksey

Perksey•10/7/23, 10:16 PM

and most of LLVM's time is spent passing over loads of those functions

Aqua

AquaOP•10/7/23, 10:16 PM

rust is a clear example of this

Perksey

P

Perksey•10/7/23, 10:16 PM

it does a good job of inlining and simplifying everything

Perksey

P

Perksey•10/7/23, 10:16 PM

but that's what's taking the time

Lyris the Kitori•10/7/23, 10:16 PM

range based for loop are great when the compiler actually lowers it reasonably

Aqua

A

AquaOP•10/7/23, 10:16 PM

yup

AquaOP•10/7/23, 10:17 PM

it does not surprise me that rust's compiler doesn't

Maxine

Maxine•10/7/23, 10:17 PM

rust was a mistake

Aqua

i would have been surprised if it did do it properly

silly goofy experimental language now used in production

Maxine

MMaxine rust was a mistake

"what if we made everything use a borrow checker?" statements dreamed up by the utterly deranged

thread safety by torturing the developer so much they decide to just make it single threaded

Aqua

A

AquaOP•10/7/23, 10:18 PM

that is

Aqua

A

AquaOP•10/7/23, 10:18 PM

true

Lyris the Kitori

Lyris the Kitori•10/7/23, 10:18 PM

just write faster code and you wont need to multithread

Aqua

A

AquaOP•10/7/23, 10:18 PM

threads made me want to launch myself off into bed

Aqua

A

AquaOP•10/7/23, 10:18 PM

ok that sounds sus but you get what i mean

Aqua

A

AquaOP•10/7/23, 10:18 PM

threads were just terrible

Aqua

all languages should come with a job system

i will die on this hill

all languages should have nouns

Maxine

i think most of them do
