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 there are e7d4b281 & bf5ca309 at the begin and end of sail's signature files: Is this a placeholder or something else?

thanks

The values you see seems to be the CANARY constant. Put at RVMODEL_DATA_BEGIN and RVMODEL_DATA_END. The value is defined in arch_test.h
