The user is reporting that qemu-arm-static crashes when running NEON code generated by GStreamer's Orc library. The problem doesn't happen in system emulation mode. The steps to reproduce involve building Orc and running a test with QEMU user mode. + +Looking at the crash details: the backtrace points to a specific address where the crash occurs. The disassembly shows NEON instructions (vld1.8, vst1.8) followed by some ARM instructions. The crash is a segmentation fault, but the user mentions it's not a memory access issue, so not a straightforward SIGSEGV from invalid memory. + +The key here is that the code runs fine in system mode but crashes in user mode. The problem is related to QEMU's handling of the generated NEON code in user-static mode. Since the code is JIT-generated, maybe QEMU isn't properly handling the code generation or execution of these instructions in user mode. The error message mentions failure to detect invalidation, which might relate to how QEMU manages code cache or translations when code is generated at runtime. + +The categories are instruction, syscall, or runtime. Since the issue is about executing generated NEON instructions and QEMU's handling of those instructions in user mode, it's likely an instruction-related problem. However, the mention of invalidation might relate to how QEMU's dynamic translation (TCG) or code caching works. But the user says it's not a memory access, so maybe it's an incorrect translation of the instructions. Alternatively, runtime errors are other runtime issues. However, since the problem is specifically with the execution of the generated code (instructions), the category would be 'instruction'. But wait, maybe the problem is that QEMU's user mode isn't handling the code invalidation when new code is generated. For example, if the JIT code is written to a memory region that QEMU isn't aware of, and thus doesn't translate it properly. That could be a runtime issue. But the error is in the actual instruction execution. Hmm. + +The description says "failure to detect invalidation". Invalidation here might refer to QEMU not detecting that new code has been generated, so it's executing old translations or invalid code. That's more about the runtime management of code regions. But the crash is during instruction execution. However, the root cause is QEMU's inability to properly handle the generated code's execution, possibly due to not updating its internal state when code is generated. This could be a runtime error. But I'm a bit torn. The instruction category is for when a specific instruction is faulty. Since the problem is about generated code not being properly handled by QEMU's execution engine (TCG), maybe it's an instruction issue. Or perhaps it's a runtime problem because it's about managing the execution environment for dynamically generated code. + +Looking at the categories again: "instruction: A faulty instruction is described in the bug report". The report shows the disassembled instructions and the crash occurs in those. But the problem isn't the instruction itself, but QEMU's handling of it. However, if QEMU's translation of that instruction is wrong, that's an instruction error. The user says the same code works in system mode, which suggests that the instruction translation in user mode is incorrect. Therefore, it's an instruction-related bug in QEMU's user mode emulation. So the category would be 'instruction'. +</think> + +instruction \ No newline at end of file |
