Problems when running executables in gem5
When I run executable file, like dhrystone.riscv, in gem5 SE mode, core dump error occurs like below.

Has anyone encountered this error? Please share a solution.
It is because at pc 0x0000000080000040 it contains high priority instructions that the Gem5 se mode cannot execute. You may need to directly modify the benchmark c file and remove the code that creates this csr instruction. E.g. remove setStats in dhrystone_main.c: line 114 and 168
I am facing the same issue. @glzhou97 your fix doesn't work. Does anyone else know how to resolve this error?
