Evgeniy Stepanov 8a1a564c46 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. llvm-svn: 249753		2015-10-08 21:35:26 +00:00
