Bug ID: 36777
Summary: Fails to emit symbols when extern "C++" used in
version script for symbols with [abi:cxx11] tag
Product: lld
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: ELF
Assignee: unassignedb...@nondot.org
Reporter: christopher.halse.rog...@canonical.com

lld test case exhibiting the bug; dump it in tests/ELF/linkerscript
LLD fails to match symbols with the [abi:cxx11] tag to extern C++ wildcards
(see attached test case).
On inspection, this appears to be because the LLVM Itanium demangler does not
have support for the ABI tag, thus the tagged symbols don't get demangled and
so the (demangled) extern "C++" symbol directives cannot match.
