Summary: While NFC for now, this will allow more flexibility on the client side to hold state necessary to back up the stream. Also when adding caching, this class will grow in complexity. Note I blindly modified the gold-plugin as I can't compile it. Reviewers: tejohnson Subscribers: mehdi_amini, llvm-commits Differential Revision: https://reviews.llvm.org/D23542 llvm-svn: 278907

|
|
// optimization and code generation on a loaded module. It is generally used
|
|
// internally by the LTO class but can also be used independently, for example
|
|
// to implement a standalone ThinLTO backend.
