Issues list

NaNs are quieted on Emscripten A-ABI Area: Concerning the application binary interface (ABI) A-floating-point Area: Floating point numbers and arithmetic A-LLVM Area: Code generation parts specific to LLVM. Both correctness bugs and optimization-related issues. C-bug Category: This is a bug. I-miscompile Issue: Correct Rust code lowers to incorrect machine code O-emscripten Target: 50% off wasm32-unknown-musl. the savings come out of stdio.h, but hey, you get SDL! T-compiler Relevant to the compiler team, which will review and decide on the PR/issue.
