Enum ModuleFlagMergeBehavior

Source

#[repr(C)]pub enum ModuleFlagMergeBehavior {
    Error = 1,
    Warning = 2,
    Require = 3,
    Override = 4,
    Append = 5,

Expand description

Must match the layout of LLVMRustModuleFlagMergeBehavior.

When merging modules (e.g. during LTO), their metadata flags are combined. Conflicts are resolved according to the merge behaviors specified here. Flags differing only in merge behavior are still considered to be in conflict.

In order for Rust-C LTO to work, we must specify behaviors compatible with Clang. Notably, ‘Error’ and ‘Warning’ cannot be mixed for a given flag.

There is a stable LLVM-C version of this enum (LLVMModuleFlagBehavior), but as of LLVM 19 it does not support all of the enum values in the unstable C++ API.
