Bug ID: 35524
Summary: [CodeView] Range-based for loop variables are not
available when debugging
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: DebugInfo
Assignee: unassignedb...@nondot.org
Reporter: ztur...@google.com
CC: amcca...@google.com, d...@google.com,

I encountered in yaml2coff.cpp. In the function layoutCOFF, there is a loop
that begins like this.
// Assign each section data address consecutively.
for (COFFYAML::Section &S : CP.Obj.Sections) {
If you put a breakpoint in this loop and hover over S, or add a watch for it,
it displays as "Variable is optimized away and not available."
This is at O0, so we really need this.
I haven't tried to make a minimal repro yet, but hopefully it's straightforward
to do. This should be easy enough for anyone to repro though.
