Hardware ASan Generating Unknown Instruction
I suspect that this is hitting the issue that I mentioned here:
https://reviews.llvm.org/D65857#1621335
We may need to do what I suggested there and restrict global tag entropy on
non-Android Linux to 7 bits. You can try working around this issue for now
by using lld as the linker (-fuse-ld=lld).

Hardware ASan Generating Unknown Instruction
Hi,
I am trying to execute a simple hello world program compiled like so:
path/to/compiled/clang -o test --target=aarch64-linux-gnu
-march=armv8.5-a -fsanitize=hwaddress
--sysroot=/usr/aarch64-linux-gnu/
-L/usr/lib/gcc/aarch64-linux-gnu/10.1.0/ -g test.c
However, when I look at the disassembly, there is an unknown
instruction listed at 0x2d51c:
000000000002d4c0 main:
2d4c0: ff c3 00 d1
