Bug ID: 49652
Summary: [RGT] QualTypeNamesTest appears to do nothing
Product: clang
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: paul_robin...@playstation.sony.com
CC: llvm-bugs@lists.llvm.org, neeil...@live.com,

clang/unittests/Tooling/QualTypeNamesTest.cpp implements a struct
TypeNameVisitor, which is derived from TestVisitor, which appears to be
for tests invoking a RecursiveASTVisitor.
This struct defines a method VisitValueDecl() to do certain tests on
the name of a ValueDecl. However, that method is never called; I can
put an 'llvm_unreachable' at the top and it never fires.
The output of running the ToolingTest suggests that QualTypeNamesTest
is actually called, but apparently something about the definition of the
struct and/or its methods keeps the test from ever doing what it looks
like it ought to be doing.
I tried fussing with it a bit (is the parameter not supposed to be const?)
but no simple tweaks made any difference. I suspect I just didn't find
the right simple tweak, but I've never used these classes myself so I'm
unsure what's missing.
Found by the Rotten Green Tests project.
