The user is reporting a bug related to QEMU regressions when running GCC tests on the arm-linux-gnueabihf target. They mentioned that after using a specific QEMU commit, even with a fix for a known bug, all the tests cause QEMU to crash. The possible categories are instruction, syscall, or runtime. + +First, I need to figure out what's causing the crashes. The problem started after updating QEMU, which suggests it's a regression. The user is running GCC tests, which are binaries compiled for ARM. The fact that QEMU crashes could be due to incorrect handling of instructions (instruction category), issues with system calls (syscall), or other runtime errors. + +Since the user mentions that the tests used to pass with QEMU 3.1 but now crash with a recent version, it's likely a regression in QEMU's handling of certain instructions or system calls. The instruction category would apply if QEMU is executing an incorrect instruction, perhaps due to a translation or emulation error. The syscall category would be if the problem is in how QEMU handles system calls made by the test programs. Runtime errors could be more general, like memory management issues or other runtime environment problems. + +The user provided a fix for a previous bug related to system calls (bug 1834496), which was about syscalls. However, even after that fix, the crashes persist. This might suggest that the current issue isn't directly related to that syscall fix. However, since the tests are crashing, it could be that the emulator is hitting some unhandled instructions or exceptions during execution. If the tests are exercising specific ARM instructions that QEMU now mishandles, that would fall under the instruction category. Alternatively, if the tests are making syscalls that QEMU isn't handling correctly, it would be syscall. But since the problem is that QEMU is crashing, which is a runtime error, maybe it's a runtime issue like a segmentation fault in QEMU itself when processing certain instructions or syscalls. + +But the categories given are instruction, syscall, or runtime. The instruction category is for when the bug is about incorrect instruction emulation. The syscall category is for syscall handling errors. Runtime is for other runtime issues. Since the user says all tests cause QEMU to crash, and it's a regression, it's possible that the QEMU emulator is encountering an unhandled instruction, leading to a crash. Alternatively, maybe a system call is being made that QEMU doesn't emulate correctly, causing a crash. However, since the user mentions that the tests are binaries and shared libraries, and the problem is that QEMU crashes when running them, it's more likely an issue within QEMU's execution of the instructions, leading to a crash. Therefore, the most likely category is instruction. But wait, maybe it's a runtime error in QEMU, like a null pointer dereference or similar when processing the test binaries. The categories are a bit ambiguous here. However, the instruction category is for when the problem is with how instructions are emulated. Since the tests are crashing QEMU, perhaps QEMU is encountering an instruction it can't handle, leading to a crash. That would be instruction. Alternatively, if QEMU is crashing due to a bug in its own code during execution, that's runtime. The problem is that the user is not providing specific details, but the key is that the tests cause QEMU to crash. Given that the user is pointing to a specific CPU configuration (cortex-a57 with crypto-neon-fp-armv8), it's possible that QEMU is not correctly emulating some specific instructions related to that CPU, leading to a crash. Therefore, the category would be instruction. However, if the crash is in QEMU's code due to a bug in the emulator, that's runtime. The challenge here is to determine whether the crash is due to QEMU not handling an instruction (instruction category) or due to a runtime error in QEMU itself (runtime category). The categories are defined as: instruction is when a faulty instruction is the issue, syscall is syscall errors, runtime is other runtime errors. Since the user's problem is that QEMU crashes when running the tests, which could be due to incorrect instruction handling (leading to a crash) or a runtime error in QEMU. Without more details, but given that the user mentions the CPU configuration and that it's a regression, I think it's more likely an instruction-related issue. So the answer would be instruction. But wait, maybe the tests are making system calls that QEMU doesn't handle, leading to a crash. However, the user mentioned that after applying a fix for a syscall-related bug, the problem still occurs. Therefore, it's less likely to be syscall. So instruction or runtime. The instruction category is for when the bug is in the instruction emulation. If QEMU is crashing because it encounters an instruction it doesn't know how to handle, that's instruction. If QEMU is crashing due to a bug in its own code (like a buffer overflow, etc.), that's runtime. Since the user is pointing to a regression in QEMU, it's possible that a recent change introduced a bug in the instruction emulation code, causing crashes. Therefore, the category is instruction. Alternatively, if the crash is in the QEMU runtime, like during execution of the emulator, it's runtime. But given that the problem is specific to certain instructions (given the CPU and FPU configuration), instruction is more likely. So I'll go with instruction. +</think> + +instruction \ No newline at end of file |
