Bug ID: 20397
Summary: globalopt removes debug info leaving incomplete
metadata
Product: clang
Version: 3.4
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs

Classification: Unclassified
Created attachment 12808

Example source where `mmu` variable metadata gets stripped after applying
globalopt
When using the globalopt optimization (every optimization level except O0) the
debug metadata is partially removed, and there is no more reference to the
global value inside the associated variable metadata. This interferes with any
subsequent passes that might make use of such debug info.
