// This file provides an abstract interface for loading a module from some
|
|
|
|
// place. This interface allows incremental or random access loading of
|
|
|
|
// functions from the file. This is useful for applications like JIT compilers
|
|
|
|
// or interprocedural optimizers that do not need the entire program in memory
|
|
|
|
// at the same time.
