The user mentioned that when running a test program on qemu-sh4, it crashes with an unhandled trap (0x180). The same code works on actual hardware (SH7785LCR), so the problem must be specific to QEMU. + +Looking at the code, it's using setcontext and makecontext, which are part of the ucontext API. These functions manipulate the context of a thread, which involves saving and restoring registers. The crash occurs when setcontext is called, which suggests that the context saved or restored by QEMU isn't correct. + +The error message mentions an unhandled trap. On SH architecture, trap 0x180 might correspond to a specific exception, perhaps related to an invalid instruction or an illegal operation. But since it's happening during context switching, it's possible that the context setup in QEMU doesn't properly handle the register state, especially thread-local storage (TLS) or some other aspects of the SH4 architecture. + +The key part here is that the code works on real hardware but not in QEMU. Since the code involves low-level context switching and thread-local storage, it's likely that QEMU's implementation of the SH4 target has an issue with how it handles the CPU state during context switches. This could be a missing or incorrect instruction emulation, especially if the context setup relies on certain CPU registers or flags that QEMU isn't correctly simulating. + +The user categorized it as part of QEMU, so the options are instruction, syscall, or runtime. Since the problem is about the correct emulation of CPU instructions during context switching, it's probably an instruction issue. The crash is due to QEMU not handling the specific instructions involved in setting up the context correctly, leading to an unhandled trap. Therefore, the category should be "instruction". +</think> + +instruction \ No newline at end of file |
