xd 13:30 < bridge> the telegram is the only app which is still working here in iran 😂 beside discord 13:30 < bridge> what about signal? 13:30 < bridge> no 13:30 < bridge> i didnt try it tho 13:30 < bridge> and we use telegram with proxy, it's the only way 13:31 < bridge> it has builtin proxies 13:35 < ChillerDragon> https://paste.zillyhuhn.com/id 13:35 < ChillerDragon> epic 13:35 < ChillerDragon> this ddnet patch causes no crashes client or server side 13:35 < ChillerDragon> i have breaking my brain on this line of code wat to do with it and its fakin unused 13:44 < bridge> (?) 13:45 < bridge> yoho, made it working 13:45 < bridge> ```cpp 13:45 < bridge> void CCharacter::RetractAttachedHooks() 13:45 < bridge> { 13:45 < bridge> CPlayer *pPlayer; 13:45 < bridge> CCharacter *pChr; 13:45 < bridge> for(int i; (i < MAX_CLIENTS) && (pPlayer = GameServer()->m_apPlayers[i]) && (pChr = pPlayer->GetCharacter()); i++) 13:45 < bridge> { 13:45 < bridge> if(pChr->Core()->HookedPlayer() == m_pPlayer->GetCID()) 13:45 < bridge> { 13:45 < bridge> pChr->m_Core.SetHookedPlayer(-1); 13:45 < bridge> pChr->m_Core.m_HookState = HOOK_RETRACT_START; 13:45 < bridge> } 13:45 < bridge> } 13:45 < bridge> } 13:45 < bridge> ``` 13:52 < bridge> cool 13:55 < ChillerDragon> pro 13:56 < bridge> ok i guess i'll simply write my macro so, that it forces to write out the captures explicitly, problem solved 😏 13:56 < bridge> compile time panic-free safe Rc 13:56 < bridge> 13:56 < bridge> take that borrow checker 13:59 < bridge> discord.gg/teensleaks 14:00 < bridge> Yikes 14:01 < bridge> @Discord Mod :banhammer: needed 14:04 < bridge> u always have weird ideas 14:06 < bridge> i am just biggest RAII & hierarchy + macro abuser 😬 14:06 < bridge> dyn dispatch? 14:06 < bridge> that was just for chillerdragons thing xd 14:06 < bridge> no related to the problem 14:06 < bridge> which restriction? 14:06 < bridge> sounds interesting 14:10 < bridge> i have a derive macro that implements a "hierarchical value" to determine if your component is higher level than another one => you can safely use Rc without leaks 14:10 < bridge> 14:10 < bridge> but if you go even further and also restrict Rc to never allow RefMut outside of your class, then you can restrict all paramters of your function to only allow lower level components => no higher level component is used inside your function. 14:10 < bridge> and thus it's not possible to borrow mut twice (this component at least) 14:10 < bridge> 14:10 < bridge> the component itself also has wrapper that hides Rc so it cannot be acccessed. 14:10 < bridge> 14:10 < bridge> So basically the goal is to never call borrow_mut, only the macros do it. 14:10 < bridge> 14:10 < bridge> and the same macros apply the restrictions to the func parameters 14:10 < bridge> hiarc best crate 14:10 < bridge> sub to it on crates.io 😏 14:11 < bridge> cool 😮 14:12 < bridge> classic squatting crate on crates.io though 😄 14:15 < bridge> https://www.memorysafety.org/blog/rustls-performance/ 14:28 < bridge> looks nice 14:28 < bridge> the title says "on track to" because it doesn't 14:52 < bridge> I hope they drop c compiler requirement soon 14:54 < bridge> What do they even use it for? 14:58 < bridge> ring uses code from boringssl from openssl for crypto primitives 15:22 < bridge> https://en.wikipedia.org/wiki/Wirth%27s_law 15:22 < bridge> @heinrich5991 @learath2 @jupeyy_keks real or nah 15:27 < bridge> unfortunately real 15:31 < bridge> Very real 15:35 < bridge> depends xd 15:35 < bridge> average software for sure 15:35 < ChillerDragon> web 15:35 < bridge> well with wasm it kida gets faster again xd 15:36 < ChillerDragon> electron 15:36 < bridge> but adoption takes years 15:36 < ChillerDragon> rust 15:36 < bridge> 😏 15:36 < bridge> runtime checks 15:36 < bridge> 😬 15:36 < ChillerDragon> gigachad C devs in 1999 had speed and segfaults 15:37 < ChillerDragon> soydev rust devs in 2024 have checks and memory safety 15:37 < ChillerDragon> there is a crate for that! 15:37 < ChillerDragon> has become the new rust developer slogan 15:38 < bridge> i always wanted to see a java runtime that disables all safety checks, not for production 15:38 < bridge> 15:38 < bridge> simply to see perf benefits xd 15:38 < bridge> 15:38 < bridge> ofc this wont really work bcs u can catch the exceptions thrown, but would still be a funny project 15:38 < bridge> in rust, disable all "hidden" panics 15:38 < ChillerDragon> which he uses for checking if numbers are even. That crate then depends on two other crates 15:38 < bridge> so those u cant unwrap 15:38 < bridge> would also be cool 15:39 < bridge> well the funny thing about rust vs c is 15:39 < bridge> that rust theoretically has perf optimizations that c can't directly have 15:39 < bridge> 15:39 < bridge> so it's harder to write faster c code than rust 15:39 < bridge> but in reality it's not the case anyway 15:43 < bridge> if llvm didnt have bugs 15:43 < bridge> https://khei4.github.io/gsoc2023/ 15:44 < bridge> > 1. Constant Propagation for uniformly patterned aggregated types on InstCombine 15:44 < bridge> > 15:44 < bridge> > Originally, no implemented constant folding can handle constant global aggregate-type values with variable index access. This was the first issue I tackled on LLVM. Throughout the project, I decided to split the problem step by step and make the patch as small as possible. 15:44 < bridge> > 2. Removal of memcpy introduced on the attributed with readonly, noalias and nocapture on MemCpyOpt 15:44 < bridge> > 15:44 < bridge> > LLVM function arguments can have attributes, i.e. noalias shows there is no other pointer variable that points to the same as the argument, and readonly shows that the argument is not modified in the function. Functions attributed noalias and readonly at the same position show invariance during the execution of the functions. If it’s also attributed with nocapture, we can omit the memcpy of argument to pass for such functions. But to completely 15:44 < bridge> > 3. Attaching wrapping flags for the switch to look up table conversion on SimplifyCFG 15:44 < bridge> > 15:44 < bridge> > This issue reports dropped nsw (no signed wrap) flags for arithmetic instructions on SimplifyCFG and InstCombine. (This is motivated by Rust Issue reported in the issue). This can be addressed by SimplifyCFG and InstCombine/InstSimplify. For the former SwitchToLookupTable on SimplifyCFG is the place to handle this. 15:44 < bridge> its ez 15:44 < bridge> > 4. Stack Move Optimization, which merges the allocas neither captured nor simultaneously used 15:44 < bridge> > 15:44 < bridge> > Rust’s move semantics introduce memcpy when values are 1) rebind to the variables, 2) passed by value to the functions. But for most cases, also due to the property of the Rust references, both pointers aren’t used simultaneously. By using alias/dataflow analysis, we could find such patterns on LLVM-IR. Originally, liveness-analysis approach was proposed, but it stalled for a long time. So I pushed forward by splitting it’s patch. 15:44 < bridge> not only that 15:44 < bridge> 15:44 < bridge> expensive optimizations take longer the more code you have 15:44 < bridge> 15:44 < bridge> so huge code bases would be really slow to compile 15:44 < bridge> 15:44 < bridge> u already see this with LTO 15:44 < bridge> which is probably not the best you could get 15:45 < bridge> U use BlmapChill? 😂 15:45 < bridge> @ryozuki btw do u also do optimizations at job? 15:46 < bridge> for llvm? 15:46 < bridge> or for our code 15:46 < bridge> i guess for the code translation 15:46 < bridge> most projects we have consistently have benchmarks and we track if there are regressions 15:47 < bridge> i c 15:47 < bridge> also flamegraphs etc 16:07 < bridge> @jupeyy_keks i got a new project at work 16:07 < bridge> its a language our company will use 16:08 < bridge> more xp with compilers kek 16:13 < bridge> yeah 16:13 < bridge> cool 16:13 < bridge> i'll soon work at chillerdragon.corp 16:14 < bridge> at grindr? 16:14 < bridge> jkjk xd 16:15 < bridge> "Grindr is the world's largest social networking app for gay, bi, trans, and queer people." 16:15 < bridge> 16:15 < bridge> chiller u gay? 16:15 < bridge> never heard about it before tbh xD 16:15 < ChillerDragon> i am not gay 16:15 < ChillerDragon> who says im gay? 16:15 < bridge> your pfp 16:15 < ChillerDragon> ah fair xd 16:16 < bridge> well supporter or LGBTQ dont need to be part of it i guess xd 16:16 < bridge> but at least it increases the chance 16:16 < ChillerDragon> jopsti u fr dont know grinder? 16:16 < bridge> no soz 16:17 < bridge> i am not the social networkist guy u'll find 16:17 < bridge> discord is my socialist network 16:17 < bridge> socialister network 16:17 < bridge> hi 16:17 < bridge> how to protect my server against bots 16:17 < ChillerDragon> wat bots 16:18 < bridge>
