Let's see the details provided. + +The problem occurs when using gdb to set a breakpoint and continue execution in QEMU-system-avr. The assertion error happens at `tb_gen_code` where it checks if `tb->size != 0`. This suggests an issue with how translation blocks are handled, which is part of the TCG (Tiny Code Generator) component used by QEMU for emulation. + +The user provided steps to reproduce: starting QEMU in system mode (since they're using `-machine uno`, which refers to an AVR board, so it's a system-level emulation), connecting via gdb, setting a breakpoint, and continuing. The problem only happens when hitting the breakpoint, not during stepping or without breakpoints. + +I remember that in QEMU, when you hit a breakpoint set by gdb (a software breakpoint), it typically involves modifying the target program to insert a trap instruction. This might involve how the CPU state is handled during translation blocks generation. If the breakpoint causes an unexpected condition in the TCG layer, like generating an empty translation block, that would trigger the assertion. + +System-mode bugs often involve device emulation, peripherals, or higher-level system functions. Since this involves CPU state and code generation for the emulated CPU (avr), it's more about how QEMU translates and executes instructions when a breakpoint is hit. The TCG layer is part of the core emulation, so issues here could be in user-mode if dealing with process-specific code but since we're talking about system-level emulation without user-space processes, this seems like a system-mode issue. + +So, considering that it's about how QEMU handles breakpoints at the CPU level during system emulation, I think this is a system-mode related bug. +</think> + +system \ No newline at end of file |
