Bug ID: 37634
Summary: MSVC can't find function symbols in lld-linked
binaries
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: DebugInfo
Assignee: unassignedb...@nondot.org
Reporter: dma...@mozilla.com
CC: llvm-bugs@lists.llvm.org, r...@google.com,
ztur...@google.com
Porting this from a Firefox bug report at
https://bugzilla.mozilla.org/show_bug.cgi?id=1458109
Using this build:
https://queue.taskcluster.net/v1/task/GoXhaNayTkig6I6H9szsYw/runs/0/artifacts/public/build/target.zip
whose PDBs are here:
https://queue.taskcluster.net/v1/task/GoXhaNayTkig6I6H9szsYw/runs/0/artifacts/public/build/target.crashreporter-symbols-full.zip
MSVC's debugger can't invoke functions in xul.dll. Member functions give a
message like: 'Function nsIFrame::DumpFrameTree has no address, possibly due to
compiler optimizations.'
Non-member functions give a message like 'identifier "DumpJSStack" is
undefined'.
This happens when the binary is linked with lld-link, regardless of whether the
compiler was cl or clang-cl. WinDbg can see these symbols with 'x' just fine,
regardless of linker.
