Hi Catalin,
I noticed there are some ELF bits for ARM's BTI feature:
GNU_PROPERTY_AARCH64_FEATURE_1_BTI
> https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/uapi/linux/elf.h#n453
There's been talk of needing a similar set of bits on x86 for tagged pointers (LAM). Do you have any plans to do something similar (ELF property bits) for any of the pointer tagging features?
