--- Comment #3 from Martin Sebor <msebor at gmail dot com> ---
Thanks for the quick patch!  I can confirm it fixes the test case I submitt=
ed
but it doesn't seem to help with the LLVM use case.  I still get the same e=
rror
-- see below.  Let me see if I can reduce it to a test case.

Breakpoint 1, llvm::LibCallSimplifier::optimizeStrLen (this=3D0x7fffffff689=
8,
CI=3D0x986a2a0, B=3D...) at
/src/llvm/llvm/lib/Transforms/Utils/SimplifyLibCalls.cpp:726
726       if (Value *V =3D optimizeStringLength(CI, B, 8))
(gdb) p CI
$1 =3D (llvm::CallInst *) 0x986a2a0
(gdb) p errs()
$2 =3D (llvm::raw_fd_ostream &) @0x979fe40: {<llvm::raw_pwrite_stream> =3D
{<llvm::raw_ostream> =3D {
  ...
(gdb) p (llvm::Value*)CI
$3 =3D (llvm::Value *) 0x986a2a0
(gdb) p *$3
$4 =3D {VTy =3D 0x9862c00, UseList =3D 0x986a350, SubclassID =3D 83 'S',=20
  ...
(gdb) p $3->print($2, false)=20
Cannot resolve method llvm::Value::print to any overloaded instance

(gdb) ptype $3
type =3D class llvm::Value {
  ...
  public:
    llvm::Value & operator=3D(const llvm::Value &);
    void deleteValue(void);
    void dump(void) const;
    void print(llvm::raw_ostream &, bool) const;
    void print(llvm::raw_ostream &, llvm::ModuleSlotTracker &, bool) const;
    void printAsOperand(llvm::raw_ostream &, bool,=20
    ...

--=20
