[cfe-commits] [PATCH] ASan: support for zero-based shadow for PIE binaries (Clang part).

[Kostya Serebryany]

  I would actually prefer a flag that says what we are doing, not what we are depending on.
  E.g. -faddress-sanitizer-zero-base (or zero-shadow-base)

  Another reason: -pie only helps on linux.
  On other platforms (e.g. Mac) other tricks will be required to enable zero-base.
