Detailed Description

A Module instance is used to store all the information related to an LLVM module.

Modules are the top level container of all other LLVM Intermediate Representation (IR) objects. Each module directly contains a list of globals variables, a list of functions, a list of libraries (or other modules) this module depends on, a symbol table, and various data about the target's characteristics.

A module maintains a GlobalList object that is used to hold all constant references to global variables in the module. When a global variable is destroyed, it should have no entries in the GlobalList. The main container class for the LLVM Intermediate Representation.

Member Enumeration Documentation

◆ ModFlagBehavior

enum llvm::Module::ModFlagBehavior

This enumeration defines the supported behaviors of module flags.

Enumerator
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.
Max	Takes the max of the two values, which are required to be integers.
Min	Takes the min of the two values, which are required to be integers.

ModFlagBehaviorLastVal
