    Before you put any money on that, got to the LLVM repo, open the ["Contributors" tab](https://github.com/llvm/llvm-project/graphs/contributors), and notice that some prominent contributors from Google (zygoloid (Richard Smith), chandlerc (Chandler Carruth), and others) have already either ceased contributing or significantly scaled down their contributions.
  • WebAssembly with Zig, Part 1
    2 projects | dev.to | 5 Aug 2022
    The beauty behind Zig is that it supports many cross-platform targets by using shims from LLVM, and almost any platform that LLVM supports, Zig will support. Let's try to write some Zig code now to add two signed integer numbers.

    BOLT is a tool originally created by Facebook engineers, now it's part of mainline LLVM. https://github.com/llvm/llvm-project/tree/main/bolt
  • A bit confuse
    2 projects | reddit.com/r/Compilers | 27 Jul 2022
    Yep, this is why a lot of people will target something like LLVM (https://llvm.org/) or another language (like transpiling to C) so they can leverage those systems to handle platform targeting.
  • What is the point of free and open source software?
    2 projects | dev.to | 27 Jul 2022
    One illustration of this came in 2015 when Stallman decided he would rather prevent the Gnu Compiler Collection from supporting modern IDE features like symbol completion, than allow GCC front ends to be paired with free-but-not-copyleft backends like LLVM and Clang: "Since LLVM and Clang are not copylefted, they invite nonfree extensions. They are a gaping hole in the defensive wall around our city." Allowing full access to GCC's internals would have obvious technical benefits, and as far as I know Stallman advanced no technical argument against the proposal. Disallowing it put the project at a significant disadvantage at a time when its influence was already waning. The message was clear: GCC exists to serve FSF, not the other way around.
  • Google's Carbon Language: An Alternative to C++ ?
    6 projects | dev.to | 24 Jul 2022
    Google recently unveiled Carbon, an experimental language that is intended to match the performance of the C++ language while supporting LLVM(Low Level Vitual Machine) and being able to interoperate with existing C++ code bases. This is a big deal because C++ is by far the most widely used language for developing HIGH performance low level systems.

    You may want to look at LLVM. It’s what’s being used as a compilation foundation to build modern languages like Rust, Zig, …
