Thanks to a colossal amount of work by Jacob Young, the x86_64 backend of Zig is now passing 101% of the behavior tests compared to the LLVM backend.
Or perhaps put another way, the LLVM backend is passing 99% of the behavior tests compared to the x86_64 backend 😉
Still a few more issues to tackle before it can be made the default, however.
@tetrislife @andrewrk Go also, if I'm not mistaken
