[VIRUS PM SCAN ERROR] Getting all users of a metadata

Hello everyone,

I was wondering is there a way to access all the IR instructions that have a specific metadata (which I create) during a link time optimization pass rather than iterating over all the basic blocks? I’m trying to compile a few MLOC and I wanted to optimize this process.

I’m using Clang 3.7, so Metadata is not a subclass of Value anymore. I was also wondering what is a use case for TrackingMDRef? Could it be used to achieve this goal?
