Hi
The latest upstream merge for libsanitizer introduces code that makes
use of some macro values that are not available in SDKs for versions
of Darwin <= 15 (macOS 10.11).
[TBH, I am a bit surprised by this, I was under the impression that upstream
supported versions back to Darwin11 / macOS 10.7]
Add definitions for these where they are not present.
tested on Darwin9 -> Darwin19 and x86_64-linux
pushed to master
thanks
Iain
P.S. I will also add this change to LOCAL_PATCHES.
libsanitizer/ChangeLog:
* sanitizer_common/sanitizer_mac.h: Ensure that TARGET_OS_
macros are defined where the macOS SDK does not contain
them.
(TARGET_OS_OSX, TARGET_OS_IOS, TARGET_OS_TV, TARGET_OS_WATCH):
Define where needed.
