Dear all, I tried to add my new ISA into Gem5. I successfully build the new ISA model, but when I simulate it with my test(generate the elf file using the llvm compiler), there was a panic "panic reserve instruction fault". Then I debug the error with GDB, and find that the simulation did not quit safely at the end of the instruction, I go on to debug and find it may have matter with "the _flag" defined in the file"flags.hh". But how the Gem5 get the _flag value from the elf file.
I don't know whether my debug is right the whole way. Or somebody has the experience of dealing with the error. I have been debug the error for several days o(�s□�t)o , and hope someone can help ~~ Thank you so much~ Xing Zhang Institute of Automation, Chinese Academy of Sciences
