Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

- Wesm assembler args overhaul?

Mention to Tristan Wellman project: Well (assembler as wesm)
I want to make a mention of tristan wellman's project called well: 'https://github.com/wellang/well', which aims to be a high level modern assembler, in case anyone knows about the assembly and wants to give support, we are trying to make an 'elf' so that it has linking support for gcc and/or any tool that handles elf compatibility with the '.o'
- Wellang announces smart array development
- (UPDATE): Wellang added function handling, and a new website!
- Wellang added support for vim syntax highlighting
-
Wellang added Vim syntax highlighting

New assembly like programming language?
Where's the new one then? https://github.com/wellang/well/blob/main/src/interp.cpp Looks like it's just converting to C++ still.
- GitHub - wellang/well: somewhat functional kinda stack based language
-
New Assembly Like Programming Language?
It appears that the language uses "return" as a synonym for the SYSCALL x86_64 instruction: https://github.com/wellang/well/blob/main/src/syscall_interp...
The example code is equivalent to:
write(1, "hello world!", 12);

Odin Programming Language

Frontend for GCC?
Have you considered QBE?
- QBE – Compiler Back End
-
What do C programmers think of the Zig language in 2023?
I really hope other new projects (like QBE) can really grow and become widely used
-
Toy C compiler, worth having an IR stage?
I really liked targetting QBE (https://c9x.me/compile/) as an IR, as it gave me lots of back-end optimisations for free 😊.
-
C or LLVM for a fast backend?
There is: QBE.

A whirlwind tour of the LLVM optimizer
You might be underestimating the accuracy of the CPU models LLVM uses.
For x86, the same data the code generator uses drives llvm-mca[1], which given a loop body can tell you the throughput, latency, and microarchitectural bottlenecks (decoding, ports, dependencies, store forwarding, etc.)—if not always precisely, then still not worse then IACA, the tool written at Intel by people who presumably knew how the CPUs work, unlike LLVM contributors and the rest of us who can only guess and measure. This separately for Haswell, Sandy Bridge, Skylake, etc.; not “x86”.
Now, is this the best model you can get? Not exactly[2], but it’s close enough to not matter. Do we often need machine code to be optimized to that level of detail? Perhaps not[3], and with that in mind you can shave at least a factor of ten off LLVM’s considerable bulk at the cost of 20—30% of performance[4,5]. But if you do want those as well, it seems that the complexity of LLVM is a fair price, or has the right order of magnitude at least.
(Frontend not included, C++ frontend required to bootstrap sold separately, at a similar markup compared to a C-only frontend with somewhat worse ergonomics.)

Made my first LLVM front-end… Now what?
You can try buildling you own backend like llvm. A good example or starting point is probably QBE since it is extremely small but very functional.
- Best book on writing an optimizing compiler (inlining, types, abstract interpretation)?
-
Rust port of B3 from WebKit, LLVM-like backend
How big is the whole backend? I've heard that it is small but I wanted to compare it to QBE which is around 8 KLoC and it is quite interesting too.
What are some alternatives?
mil - A small, concatenative programming language. Implemented in C99.
ubpf - Userspace eBPF VM
hook - The Hook Programming Language
minivm - A VM That is Dynamic and Fast
go.vm - A simple virtual machine - compiler & interpreter - written in golang
mir - A lightweight JIT compiler based on MIR (Medium Internal Representation) and C11 JIT compiler and interpreter based on MIR
felix - The Felix Programming Language
wasmtime - A fast and secure runtime for WebAssembly
KAI - KAI is a distributed computing model written in modern C++ and is cross-plaftorm. Using custom language translators and an executor, KAI provides full reflection, persistence and cross-process communications without having to modify existing source code. KAI Comes with an automated, generational tricolor garbage collector, and Console- and Window-based interfaces.
