Expand description

Defines the operational behavior for a module wide flag. This documenation comes directly from the LLVM docs

Variants

Error

Emits an error if two values disagree, otherwise the resulting value is that of the operands.

Warning

Emits a warning if two values disagree. The result value will be the operand for the flag from the first module being linked.

Require

Adds a requirement that another module flag be present and have a specified value after linking is performed. The value must be a metadata pair, where the first element of the pair is the ID of the module flag to be restricted, and the second element of the pair is the value the module flag should be restricted to. This behavior can be used to restrict the allowable results (via triggering of an error) of linking IDs with the Override behavior.

Override

Uses the specified value, regardless of the behavior or value of the other module. If both modules specify Override, but the values differ, an error will be emitted.

Append

Appends the two values, which are required to be metadata nodes.

AppendUnique

Appends the two values, which are required to be metadata nodes. However, duplicate entries in the second list are dropped during the append operation.
