(In reply to Mark Millard from comment #9)

The only source code that I find with:

_ZZN4llvm7hashing6detail18get_execution_seedEvE4seed

(So: namespace llvm::hashing::detail:: ) is:

/wrkdirs/usr/ports/devel/llvm60/work/llvm-6.0.1.src/include/llvm/ADT/Hashing.h
's:

. . .
namespace llvm {
. . .

// All of the implementation details of actually computing the various hash
// code values are held within this namespace. These routines are included in
// the header file mainly to allow inlining and constant propagation.
namespace hashing {
namespace detail {
. . .

/// \brief A global, fixed seed-override variable.
///
/// This variable can be set using the \see llvm::set_fixed_execution_seed
/// function. See that function for details. Do not, under any circumstances,
/// set or read this variable.
extern size_t fixed_seed_override;

inline size_t get_execution_seed() {
  // FIXME: This needs to be a per-execution seed. This is just a placeholder
  // implementation. Switching to a per-execution seed is likely to flush out
  // instability bugs and so will happen as its own commit.
  //
  // However, if there is a fixed seed override set the first time this is
  // called, return that instead of the per-execution seed.
  const uint64_t seed_prime = 0xff51afd7ed558ccdULL;
  static size_t seed = fixed_seed_override ? fixed_seed_override
                                           : (size_t)seed_prime;
  return seed;
}
