Select the LLVM version to be compatible with.
You _must_ enable exactly one of the following features. - llvm-10 = llvm-10-or-greater, llvm-10-or-lower, llvm-sys-100
- llvm-11 = llvm-11-or-greater, llvm-11-or-lower, llvm-sys-110

- llvm-15 = llvm-15-or-greater, llvm-15-or-lower, llvm-sys-150
- llvm-16 = llvm-16-or-greater, llvm-16-or-lower, llvm-sys-160

For convenience, these automatically-enabled features allow us to avoid checking complex combinations of features all the time. They are not meant to be manually enabled; use the above llvm-x features instead

- strict-versioning
-
The
strict-versioningfeature requires an exact match between the system LLVM version and the version selected with the above features.The
?in the below ensures that we only enable the feature if the dependency is already present. This avoids activating all the optional dependencies whenstrict-versioningis activated.Enables strict-versioning of optional llvm-sys ^100.2.0, optional llvm-sys ^110.0.0, optional llvm-sys ^120.2.0, optional llvm-sys ^130.0.0, optional llvm-sys ^140.0.0, optional llvm-sys ^150.1.0, optional llvm-sys ^160.1.2, optional llvm-sys ^170.0.1, and optional llvm-sys ^90.2.0
- prefer-dynamic
-
The
prefer-dynamicfeature is only available on llvm-sys versions >= 120.Enables prefer-dynamic of optional llvm-sys ^120.2.0, optional llvm-sys ^130.0.0, optional llvm-sys ^140.0.0, optional llvm-sys ^150.1.0, optional llvm-sys ^160.1.2, and optional llvm-sys ^170.0.1
Features from optional dependencies
In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
