-Subject: [PATCH] New MSan mapping layout (llvm part).
-
-This is an implementation of
-https://github.com/google/sanitizers/issues/579
-
-It has a number of advantages over the current mapping:
-* Works for non-PIE executables.
-* Does not require ASLR; as a consequence, debugging MSan programs in
-  gdb no longer requires "set disable-randomization off".
-* Supports linux kernels >=4.1.2.
-* The code is marginally faster and smaller.
-
-This is an ABI break. We never really promised ABI stability, but
-this patch includes a courtesy escape hatch: a compile-time macro
-that reverts back to the old mapping layout.
