Test having multiple OpenGL versions in the same window with rust-sdl2 (spoiler: it works!)
use sdl2::video::{GLContext, GLProfile, Window};

fn test_opengl(
video_ctx: &VideoSubsystem,
window: &Window,

Rust no_std “hello world” compiled to C!

Requires rustc and llvm-cbe.

  • rustc hello-world-no_std.rs -O --emit=llvm-ir -C panic=abort -o hello-world-no_std-O.ll
  • llvm-cbe ../testfiles/hello-world-no_std-O.ll
