+// Test lldb is able to compute the fully qualified names on templates with

+// REQUIRES: lld

+// Test against logging to see if we print the fully qualified names correctly.

+// RUN: %lldb %t -o "log enable dwarf comp" -o "target variable v1 v2" -o exit | FileCheck %s --check-prefix=LOG

+// Test that we following DW_AT_signature correctly. If not, lldb might confuse the types of v1 and v2.

No, they are not affected by this patch. When I working on this change, I had an oversight on not calling `DWARFDIE::resolveTypeUnitReference` in https://github.com/llvm/llvm-project/pull/112811/files/3fc0675398547617731d0501e3d4b98e2ffc480e#diff-5e94a4eb2c54c062b27821639b3c2732886de49229c99b11b6b2602f35b0ccdcR788 and existing lldb tests didn't catch it. So, I added this for test coverage.
