llvm-project VS git

This reminds me of a similar issue in LLVM's `raw_svector_ostream`. Before a 2015 commit https://github.com/llvm/llvm-project/commit/3d1173ba1a53cab0... ,

Huh? Quoting a bit more from the article:

> [W]e find this in ARM.cpp:

> trapInstr = {0xd4, 0xd4, 0xd4, 0xd4};

The only thing left to explain is that the trap instruction is used as padding, but you can’t tell from here if that’s obvious or not. Opening the actual code[1], we see that the occurrences of trapInstr are all along the lines of

> void ARM::writePlt( /* ... / ) {

> / ... */

> memcpy(buf + 12, trapInstr.data(), 4); // Pad to 16-byte boundary

which isn’t the absolute best, but seems clear enough (if of course you know what a PLT is, which you should if you’re writing a linker).

I do think this merits an explanation that we’re using (what’s intended to be) a trap because the traditional option of using a nop makes ASLR less effective. But then the commit message you’re quoting doesn’t mention that either.

Certainly compiler developers are only human, and many of them write C++ so they're humans working with a terrible programming language, I wouldn't sign up for that either (I have written small contributions to compilers, but not in C++). I still don't see "any excuses". I see more usual human laziness and incompetence, LLVM for example IMNSHO doesn't work hard enough to ensure their IR has coherent semantics and to deliver on those semantics.

The compiler bug I'm most closely following, and which I suspect you have your eye on too is: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=119472 aka https://github.com/rust-lang/rust/issues/107975 https://github.com/llvm/llvm-project/issues/45725

But it seems like it's just that everybody fucked this up in similar ways, that's two different major compiler backends! I wouldn't be surprised if Microsoft (whose code we can't see) find that they don't get this quite right either.

My ideal array language is one in which array operations are function compositions, since arrays are functions. A functional view of array expressions naturally minimizes needless temporaries in most cases.

Lightweight UI for Github? (Idk if that exists).

e.g. client requests https://github.mx/llvm/llvm-project, your server fetches the data from https://github.com/llvm/llvm-project (using an API or scraping the site), and renders it in a cleaner UI with less HTML and JavaScript.

It would be useful for slow/outdated devices and places with low internet bandwidth. The URL concept is similar to https://github.dev/llvm/llvm-project which opens the project in a web-hosted VSCode (so vaguely the opposite approach).

- Testing: llvm-lit tests validate the analysis by checking the generated facts.

Example:

[LifetimeSafety] Introduce intra-procedural analysis in Clang

> still is the main company behind LLVM.

lol people really say whatever comes to their mind around here don't they? I'm pretty sure all of the companies associated with these targets would strongly disagree with you

The most interesting part of this post is the bit about half way down, where Alex uses Claude to help identify a missing compiler optimization in LLVM... and then uses Claude Code to implement that optimization and gets a PR accepted to LLVM itself! https://github.com/llvm/llvm-project/pull/142869

it's mostly upstream now, no need to dig around in their repos

Download Git Bash. This is a tool developers use to write Git commands on a PC. I use this on my computer. Just go to gitforwindows.org and click the download button to start downloading the file.

Go to the Git for Windows website.

At work when I work on Windows (currently stuck using Mac for the first time in my career at work), but on Windows I would use https://gitforwindows.org/ which also uses msys2 and that is a very popularly supported free product using msys2 on Windows. If you ever forget the URL, search for "git bash for windows".

Git installed and configured on your machine. For Windows, For Mac

How to install?? Before going further make sure you have installed GIT BASH because these commands will not work on windows terminal. Before installing foundry we need to install latest version of the rust. To install rust run below command in your bash terminal

Install gitbash 😸

I use windows, mac and linux basically interchangeably for coding. For windows, I install the Git Bash package [https://gitforwindows.org/] and then just use chocolatey as a package manager for stuff like python and node.js. Bash gives me a completely functional commandline with my C drive mounted as `/c`, and I can write code using VSCode. I don't really have issues. With this setup, it operates indistinguishably from the other two platforms.

For me, the key really is the commandline. Learning powershell is not something I'm going to do.

Mac (OSX) • Windows • Linux

For more information on the Git for Windows project, which is separate from Git itself, you can visit https://gitforwindows.org.
