takes 5 minutes to compile

that's just any rust program

MMaxine you can wait ONE YEAR beyley i've been waiting like 15 for better generics

Lyris the Kitori•10/7/23, 10:11 PM

well i need it right now as im writing code right now that would mildly benefit safety wise from it

AquaOP•10/7/23, 10:11 PM

true

Maxine•10/7/23, 10:11 PM

LLVM needs to spend 7 days compiling your program into nothing

TechPizza•10/7/23, 10:12 PM

you're doing it wrong if you're not compiling linux kernel+llvm+clang+rust+cargo before your hello world

Lyris the Kitori•10/7/23, 10:12 PM

inline the whole ass app into the OS

AquaOP•10/7/23, 10:12 PM

idk what it is with cargo and WSL2 but yeezus
i almost fell asleep trying to wait for it to finish

LLyris the Kitori inline the whole ass app into the OS

Maxine•10/7/23, 10:12 PM

welcome to android

Lyris the Kitori•10/7/23, 10:12 PM

real

Maxine•10/7/23, 10:12 PM

the source tree is THE WHOLE THING

AAqua idk what it is with cargo and WSL2 but yeezus i almost fell asleep trying to wai...

TechPizza•10/7/23, 10:12 PM

say hello to WSL IO being android-level fast

Maxine•10/7/23, 10:12 PM

wonder if i can build that on github actions, it only needs like 150gb free space

TTechPizza say hello to WSL IO being android-level fast

AquaOP•10/7/23, 10:12 PM

apparently so

AquaOP•10/7/23, 10:13 PM

WSL2 cant even handle audio properly it seems lmfao

AquaOP•10/7/23, 10:13 PM

which is
annoying

TTechPizza say hello to WSL IO being android-level fast

Maxine•10/7/23, 10:13 PM

usermode -> kernelmode -> usermode -> kernelmode -> write to disk

Lyris the Kitori•10/7/23, 10:13 PM

WSL1 was banger im mad they didnt continue with it

LLyris the Kitori WSL1 was banger im mad they didnt continue with it

Maxine•10/7/23, 10:13 PM

AGREED

Maxine•10/7/23, 10:13 PM

fire take

AquaOP•10/7/23, 10:13 PM

why what was the difference

Maxine•10/7/23, 10:13 PM

still have wsl1 installed

AAqua why what was the difference

Maxine•10/7/23, 10:14 PM

it's not just a VM

AAqua why what was the difference

Lyris the Kitori•10/7/23, 10:14 PM

WSL1 wasnt a whole VM

AquaOP•10/7/23, 10:14 PM

ahhh ok

Lyris the Kitori•10/7/23, 10:14 PM

it literally ran the linux apps

Lyris the Kitori•10/7/23, 10:14 PM

on windows

AquaOP•10/7/23, 10:14 PM

nice

Maxine•10/7/23, 10:14 PM

they actually implemented part of the linux kernel on NT

AquaOP•10/7/23, 10:14 PM

im guessing it was too much effort for ol' mikey to continue on with it i guess

TechPizza•10/7/23, 10:14 PM

we can't have nice things

Lyris the Kitori•10/7/23, 10:14 PM

its why its called the "windows subsystem for linux"

Lyris the Kitori•10/7/23, 10:14 PM

since WSL1 was a whole NT personality iirc

AAqua im guessing it was too much effort for ol' mikey to continue on with it i guess

Maxine•10/7/23, 10:14 PM

no, it couldn't go GPU acceleration for machine learning so they ditched it

AquaOP•10/7/23, 10:15 PM

l o l

Lyris the Kitori•10/7/23, 10:15 PM

they COULD have just piped D3D12 in there like they did with WSL2

AquaOP•10/7/23, 10:15 PM

~~people care about machine learning?~~

MMaxine that's just any rust program

Perksey•10/7/23, 10:15 PM

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..3for 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

AAqua ~~people care about machine learning?~~

Lyris the Kitori•10/7/23, 10:15 PM

people care about money
and machine learning makes money

AquaOP•10/7/23, 10:15 PM

tru

PPerksey i was looking into that, it's because of silly things like it having to traverse...

Maxine•10/7/23, 10:15 PM

what the fuck

Maxine•10/7/23, 10:15 PM

at this point maybe llvm should special case rustc output

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•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

AquaOP•10/7/23, 10:16 PM

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

AquaOP•10/7/23, 10:16 PM

cause unless you compile it properly

AquaOP•10/7/23, 10:16 PM

that aint gonna be faster

Perksey•10/7/23, 10:16 PM

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

AquaOP•10/7/23, 10:16 PM

rust is a clear example of this

Perksey•10/7/23, 10:16 PM

it does a good job of inlining and simplifying everything

takes 5 minutes to compile
