Hi Zhaoshi,
Currently there's no global tagging instrumentation for MTE. We have a good idea about the implementation's design - but no patch...

[MTE] Tagging Globals
Hello,
We're evaluating memory tagging (MTE) on some internal workloads.
We noticed that stack variables are tagged by an instrumentation pass and heap objects are handled by the allocator (Scudo).
How about global variables? We tried a simple case using -march=armv8a+memtag -fsanitize=memtag, but found no tagging:
Are we missing anything or tagging globals is still in progress?
