Prevent insta-stable no alloc shim support You will need to add the following as replacement for the old __rust_* definitions when not using the alloc shim. #[no_mangle] static __rust_no_alloc_shim_is_unstable: u8 = 0; 2022-09-10 06:33:44 -05:00			`#![crate_type = "lib"]`
Upgrade LLVM Includes https://github.com/rust-lang/llvm/pull/80 Includes https://github.com/rust-lang/llvm/pull/79 Also adds tests and thus fixes #24194 2017-06-03 07:07:57 -05:00
