The categories provided are: mistranslation, assembly lowering, other, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor. + +Looking at the description of the problem, it's about breakpoints being set at the wrong addresses in a test script for QEMU's GDB stub. Specifically, the issue occurs when testing with certain Linux kernel guest images compiled on macOS arm64. + +The user explains that the script sets breakpoints not at the function start but at the end of their prologues. This causes the tests to fail because the breakpoint address doesn't match the expected function start address. The problem arises when these functions have prologues, which is common in some kernel builds. + +So, why does this happen? It seems related to how GDB interprets the function addresses. In the provided example, setting a breakpoint on `kernel_init()` gives two different addresses: one at the prologue start and another at the function's actual start. This discrepancy causes the test script to fail because it compares the stopped address (end of prologue) with the function's start. + +The proposed fix is to modify how breakpoints are set in the script by explicitly adding an asterisk before the function name, which tells GDB to set the breakpoint at the exact specified address rather than decoding the prologue. This should align the breakpoint with the function's actual start. + +Now, considering the categories: + +- **Mistranslation** usually refers to incorrect semantic mapping from source to target, but this isn't a translation issue. +- **Assembly lowering** is about converting high-level code to assembly, which doesn't seem relevant here. +- **Debug** relates to debugging tools and their behavior. The issue is within the GDB stub and how breakpoints are handled in tests, so debug seems appropriate. +- Other categories like device, graphic, etc., don't fit since this is about debugging functionality. + +Therefore, the bug falls under the 'debug' category because it's related to how QEMU handles breakpoints during debugging sessions with the GDB stub, specifically when interacting with certain kernel builds that include function prologues. +</think> + +debug \ No newline at end of file |
