...pends on thread support for mutex & storing unsafe stack pointer. It also need several system calls: gettid, tgkill, mmap, munmap, mprotect. Our target doesn't has all underlying support it needs. My question is: what's the minimum requirement to port Safe Stack to bare metal? Thanks, Zhaoshi -------------- next part -------------- An HTML attachment was scrubbed...

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? int
