+Subject: [PATCH] New MSan mapping layout (compiler-rt 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.
+
+git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@249754 91177308-0d34-0410-b5e6-96231b3b80d8

++Abi Tags
++========
++
++Introduction
++============
++
++This text tries to describe gcc semantic for mangling "abi_tag" attributes
++described in https://gcc.gnu.org/onlinedocs/gcc/C_002b_002b-Attributes.html
++
++There is no guarantee the following rules are correct, complete or make sense
++in any way as they were determined empirically by experiments with gcc5.
++
++Declaration
++===========
++
++Abi tags are declared in an abi_tag attribute and can be applied to a
++function, variable, class or inline namespace declaration. The attribute takes
++one or more strings (called tags); the order does not matter.
++
++See https://gcc.gnu.org/onlinedocs/gcc/C_002b_002b-Attributes.html for
++details.
++
++Tags on an inline namespace are called "implicit tags", all other tags are
++"explicit tags".
++
++Mangling
++========
++
++All tags that are "active" on a <unqualified-name> are emitted after the
++<unqualified-name>, before <template-args> or <discriminator>, and are part of
++the same <substitution> the <unqualified-name> is.
++
++They are mangled as:
++
++ <abi-tags> ::= <abi-tag>* # sort by name
++ <abi-tag> ::= B <tag source-name>
++
++Example:
++
++ __attribute__((abi_tag("test")))
++ void Func();
++
++ gets mangled as: _Z4FuncB4testv (prettified as `Func[abi:test]()`)
++
++Active tags
++===========
++
++A namespace has never any active tags; for types (class / struct / union /
++enum) the explicit tags are the active tags.
++
++For variables and functions the active tags are the explicit tags plus any
++"required tags" which are not in the "available tags" set:
++
++ derived-tags := (required-tags - available-tags)
++ active-tags := explicit-tags + derived-tags
++
++Required tags for a function
++============================
++
++If a function is used as a local scope for another name, and is part of
++another function as local scope, it doesn't have any required tags.
++
++If a function is used as a local scope for a guard variable name, it doesn't
++have any required tags.
++
++Otherwise the function requires any implicit or explicit tag used in the name
++for the return type.
++
++Required tags for a variable
++============================
++
++A variable requires any implicit or explicit tag used in its type.
++
++Available tags
++==============
++
++All tags used in the prefix and in the template arguments for a name are
++available; for functions also all tags from the <bare-function-type> (which
++might include the return type for template functions) are available.
++
++For <local-name>s all active tags used in the local part (<function-
++encoding>) are available, but not implicit tags which were not active!
++
++Implicit and explicit tags used in the <unqualified-name> for a function (as
++in the type of a cast operator) are NOT available.
++
++Example: a cast operator to std::string (which is
++std::__cxx11::basic_string<...>) will use 'cxx11' as active tag, as it is
++required from the return type `std::string` but not available.

++ // For functions and variables there is a set of "implicitly available"

++ //
++ // Now all tags from the function return type/variable type which are not
