Bug ID: 35014
Summary: Need a way to disable "warning: symbol scopes are not
balanced in" for system libraries
Product: lld
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: COFF
Assignee: unassignedb...@nondot.org
Reporter: nicolaswe...@gmx.de
CC: llvm-bugs@lists.llvm.org
If I build chromium with lld, virtually every link prints this:
[15895/50568] LINK(DLL) swiftshader/libGLESv2.dll swiftshader/libGLESv2.dll.lib
swiftshader/libGLESv2.dll.pdb
../../third_party/llvm-build/Release+Asserts/bin/lld-link: warning: symbol

This is not interesting and actionable for application developers (...unless
some flag we uses causes this?). So it shouldn't be printed.
Also, it'd be good if there was a way to consistently enable warnings-as-errors
for lld. In Chromium, our philosophy about warnings is in general "if it's an
interesting warning, it deserves to be made an error, else it shouldn't be
printed at all".
