Let's break it down step by step. + +First, the user describes that they're running Perlbench from the SPEC suite using qemu-x86_64 and encountering crashes. They've tried this on three machines, two of which resulted in crashes. The error message is "Illegal instruction," and they provided some debugging output with instructions leading up to the crash. + +Looking at the debugging output, there's a section where an instruction ".byte 0x62" appears. This seems odd because it's just a single byte without an opcode that makes sense in this context. The instruction before that is "movq %rdx, 0xc0(%rbx)", which looks normal. + +The crash occurs with signal 4, which corresponds to SIGILL—meaning an illegal instruction was encountered. This suggests that QEMU is executing an invalid x86_62 instruction or misinterpreting valid instructions in a way that causes the CPU to throw this error. + +Now, considering the categories provided: + +1. **Instruction**: This category refers to issues where a specific instruction is causing problems. Given that the crash happens at a particular point and the last instruction before the crash is ".byte 0x62", which doesn't translate into a valid x86_64 instruction, it's possible that this byte is being treated as an instruction. Alternatively, perhaps QEMU is incorrectly handling certain instructions from the benchmark. + +2. **Syscall**: This would involve issues with system calls. However, in the provided information, there's no mention of syscalls or any indication that a syscall is causing the problem. The error seems to be happening during normal execution, not when making a system call. + +3. **Runtime**: This category covers other runtime errors that aren't specifically related to instructions or syscalls. Since the crash is due to an illegal instruction, it's more about how QEMU handles the instruction set rather than a general runtime issue. + +Given that the error is directly tied to executing an invalid instruction and the presence of a ".byte 0x62" which might not be intended as a valid x86_64 opcode, this points towards an instruction-related problem. It's possible that either the benchmark is generating invalid instructions or QEMU isn't correctly emulating certain instructions, leading to this crash. + +Therefore, the most appropriate category for this bug report is "instruction." +</think> + +instruction \ No newline at end of file |
