Let me read through the problem carefully. + +The user is reporting that Go programs crash on qemu-sh4 but work fine on the actual hardware (SH7785LCR SH4 evaluation board). The issue seems related to atomics in QEMU's SH4 implementation. There's a backtrace pointing to issues with atomic.Load64 and runtime_mstart, which are part of the Go runtime's handling of concurrency or memory. + +The user also mentions that after fixing commit #1738545, Go works on qemu-arm but not on qemu-sh4. Additionally, they note that reverting another commit (61dedf2af7) changes how the crash occurs, indicating that QEMU's behavior is affected by specific code changes in its repository. + +Looking at the possible categories: mistranslation, assembly lowering, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor, and other. + +The issue here seems to be with how QEMU emulates atomic operations for the SH4 architecture. Since Go uses atomics heavily in its runtime, especially for concurrency, any incorrect translation or handling of these instructions by QEMU could cause crashes. + +"Mistranslation" refers to incorrect mapping from source (like user-mode code) to IR or target instructions. In this case, QEMU might be mishandling atomic operations when translating SH4 instructions, leading to the Go runtime's panic. Alternatively, "assembly lowering" might also be a possibility since it involves converting high-level operations into machine code, but the root cause seems more about how specific instructions are translated rather than the assembly process itself. + +Other categories like device or network don't seem relevant here because the issue is with CPU-related functions (atomics). The problem isn't with hardware peripherals or networking; it's purely a software emulation issue in QEMU. + +So, considering all this, the most appropriate category for this bug would be "mistranslation" because it's an incorrect handling of certain instructions during the translation process from the source architecture (SH4) to the target environment in QEMU. +</think> + +The crash is caused by issues with how atomics are handled in the QEMU SH4 emulation, which falls under incorrect instruction translation. + +**Answer:** mistranslation \ No newline at end of file |
