Bug ID: 23045
Summary: Dropping old debug metadata requires reading all
function bodies upfront
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Bitcode Reader
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
UpgradeDebugInfo will drop all the old debug info it can see.
Unfortunately, if the module is being lazily loaded, it will miss stuff from
the function bodies.
When the bodies are finally read, the module becomes invalid.
This manifests as a crash in ~/llvm/llvm/test/tools/gold/drop-debug.ll
