CRITICAL Cannot randomize branch target instruction
thewesley77 opened this issue · 1 comments
I have been unsuccessful at generating any test in the base test list other than the 'riscv_arithmetic_basic_test'. Most of the test that I try get a CRITICAL issue in the log file and cause the program to hang and does not produce a ASM file. In this example I ran the command:
python3 run.py --test=riscv_loop_test --simulator=pyflow --steps gen --target rv32i
But it never finished and when I checked the log file I see the following error for the riscv_loop_test:

Do I have something wrong with the command or the install that is causing the other tests to take these critical issues?
Thanks

I've managed to reproduce the issue and am looking into possible fixes
