bors a1411de9de Auto merge of #86267 - ZuseZ4:master, r=nagisa ... Allow loading of llvm plugins on nightly Based on a discussion in #82734 / with `@wsmoses.` Mainly moves [this](0149bc4e7e) behind a -Z flag, so it can only be used on nightly, as requested by `@nagisa` in https://github.com/rust-lang/rust/issues/82734#issuecomment-835863940 This change allows loading of llvm plugins like Enzyme. Right now it also requires a shared library LLVM build of rustc for symbol resolution. ```rust // test.rs extern { fn __enzyme_autodiff(_: usize, ...) -> f64; } fn square(x : f64) -> f64 { return x * x; } fn main() { unsafe { println!("Hello, world {} {}!", square(3.0), __enzyme_autodiff(square as usize, 3.0)); } } ``` ``` ./rustc test.rs -Z llvm-plugins="./LLVMEnzyme-12.so" -C passes="enzyme" ./test Hello, world 9 6! ``` I will try to figure out how to simplify the usage and get this into stable in a later iteration, but having this on nightly will already help testing further steps.		2021-06-26 19:20:41 +00:00
