e7d4b281 & bf5ca309 in the ref's signature

[hyperion009]

Hi
it's a first time for me to run a riscv-arch-test. I am using the sail as a reference and find that there are e7d4b281 & bf5ca309 at the begin and end of sail's signature files:

Is this a placeholder or something else?

thanks

This are "canary" words which are present to catch errors that go beyond the bounds of the signature region. If those words are overwritten, then the framework knows that something went wrong. (Assuming that Sail is correct, it would see a signature difference, so it knows the DUT is acting improperly)
