Let's break down the information provided. + +First, the user provided a Go program that runs fine on their physical SH7785LCR board but crashes when run under qemu-sh4. The backtrace shows a panic related to atomics and mentions functions like runtime_mstart in the proc.c file. They also mention that reverting a specific commit changes the crash behavior. + +From what I understand, user-mode issues typically involve problems with application-level code or libraries running in user space. System-mode issues are more about the kernel, device drivers, hardware interactions, etc., which run in privileged mode. + +In this case, the crash is happening when the Go runtime uses atomic operations. Since Go's runtime manages its own threading and scheduling, which includes handling goroutines and such, it might be interacting with low-level system calls or memory management that could involve kernel-space operations. However, the panic itself seems to originate from within the Go runtime's internal functions related to atomics. + +But wait, the fact that this is happening in qemu-sh4 suggests it's an emulation issue. Maybe the emulator isn't correctly handling certain instructions or system calls that are required for atomic operations on SH4 architecture. That would be a system-level problem because emulators need to accurately replicate hardware behavior at a low level. + +Also, the user mentioned that reverting a specific commit changes how the application crashes. This points towards an issue in how qemu handles some aspect of the SH4's CPU or memory model, which is critical for correct atomic operation emulation. If qemu isn't properly emulating atomic operations (like Load64), it could cause the runtime to panic, especially since Go relies heavily on these for concurrency. + +Another angle: Go programs can sometimes have issues with their own runtime if the underlying system doesn't support certain features. But since the same program runs fine on the physical board, it's more likely that qemu isn't correctly emulating something related to atomics or thread management at a lower level than user space. + +Putting it all together, the crash seems tied to how qemu is handling atomic operations in its emulator for SH4. This involves low-level CPU instructions and memory access patterns, which are system-mode concerns. Therefore, this bug report should be classified as 'system' related. +</think> + +system \ No newline at end of file |
