            Bug ID: 37645
           Summary: Clang could diagnose failure to construct a pair w/
                    braced init sequence better
           Product: new-bugs
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org

Hacking on LLVM I got the following diagnostic:

/home/chandlerc/src/llvm/project/llvm/lib/Transforms/Scalar/SimpleLoopUnswitch.cpp:1932:26:
error: no matching member function for call to 'push_back'
      UnswitchCandidates.push_back({BI, {BI->getCondition()}});
      ~~~~~~~~~~~~~~~~~~~^~~~~~~~~
/home/chandlerc/src/llvm/project/llvm/include/llvm/ADT/SmallVector.h:212:8:
note: candidate function not viable: cannot convert initializer list argument
to 'const std::__1::pair<llvm::TerminatorInst *,
llvm::TinyPtrVector<llvm::Value *> >'
  void push_back(const T &Elt) {
       ^
/home/chandlerc/src/llvm/project/llvm/include/llvm/ADT/SmallVector.h:219:8:
note: candidate function not viable: cannot convert initializer list argument
to 'std::__1::pair<llvm::TerminatorInst *, llvm::TinyPtrVector<llvm::Value *>
>'
  void push_back(T &&Elt) {
       ^

The problem is that TinyPtrVector<T> doesn't have an initializer list
constructor.
