Do not pass through features without +/- prefix LLVM really dislikes this and will assert, saying something along the lines of: ``` rustc: llvm/lib/MC/MCSubtargetInfo.cpp:60: void ApplyFeatureFlag( llvm::FeatureBitset&, llvm::StringRef, llvm::ArrayRef<llvm::SubtargetFeatureKV> ): Assertion `SubtargetFeatures::hasFlag(Feature) && "Feature flags should start with '+' or '-'"` failed. ``` 2021-07-23 14:42:36 +03:00			`// compile-flags: -Ctarget-feature=rdrand --crate-type=rlib --target=x86_64-unknown-linux-gnu`
