Bug ID: 22111
Summary: Add concept of 'distinct' MDNodes
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Core LLVM classes
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
We should have the ability to explicitly create distinct MDNodes, which are not
uniqued, without having to resort to self-references.
This is relatively easy:
1. Add API.
2. Add assembly and bitcode support for saving this bit (it's already used
under the hood for uniquing collisions, but it's not serialized).
3. Add logic to `ValueMap` so that it's kept there too.
