Let me read through the bug report carefully. + +The problem occurs when executing a RISC-V compressed instruction with the C extension disabled in QEMU. The user provided steps to reproduce it using an assembly program and specific QEMU command-line options. The assertion failure happens at `translate-all.c:762`, which is part of the TCG (Translation Cache Generator) code. + +Looking at the crash details, it seems like when a compressed instruction is encountered but C extension is disabled, instead of trapping correctly, QEMU crashes. The debug output shows that the translation block (TB) has size zero, leading to an assertion failure. + +The provided assembly code includes a loop with a `bne` instruction and uses `lui`, which are standard RISC-V instructions. However, the comment mentions using a compressed instruction when C is disabled. So, the issue arises specifically when trying to execute a compressed instruction in a QEMU setup without enabling the C extension. + +Now, thinking about user-mode vs system-mode: User-mode issues usually relate to the CPU or software running in user space, while system-mode involves higher privileges, devices, peripherals, or the OS interacting with hardware. + +In this case, the crash is happening during instruction translation, which is part of the CPU emulation. The error occurs when processing an instruction that's not supported because the C extension is disabled. This seems more related to how QEMU handles CPU instructions rather than any system-level components like devices or peripherals. + +Therefore, this issue likely falls under user-mode since it's about the CPU executing instructions and handling exceptions without involving higher privilege levels or device interactions. +</think> + +user \ No newline at end of file |
