--- Comment #2 from Rhys Kidd <rhysk...@gmail.com> ---
Initial patch set attached that brings up macOS 10.12 support.
Patches against r15949, that allow valgrind and test suite to build on macOS
10.12.
Valgrind binaries do not yet run on macOS 10.12, due to an error mapping the
NULL page during load of /usr/lib/dyld, see output below:

valgrind: mmap-FIXED(0x0, 253952) failed in UME (load_segment1) with error 12
(Cannot allocate memory).
On OS X 10.11, that equivalent last mmap is at a higher base address:
