> Hard-coded build page size values may work for your system, but generally isn't reliable.

Yes, you are right. It is not  I have no reliable. I have no better idea on it. I defined a new command option "hwasan-sys-page-size", It can be used as following:

  $ clang -fsanitize=hwaddress -mllvm -hwasan-sys-page-size=8k example.c
