Let me read through it carefully and understand what's being reported. - -The user is pointing out that there's no check for unaligned data access in ARM32 instructions within QEMU. They mention that according to ARM documentation, load/store instructions like LDRD, STRD, LDREX, STREX must have word alignment, regardless of the value of SCTLR.A. However, it seems QEMU isn't implementing this check, which is against the documentation. - -They provided a test case where an instruction at VA 0x10240 uses ldrd r0,[pc.#1], and in QEMU 5.1.0, it loads data from an unaligned address without any issue. The user suggests that during translation to TCG (which I think is the target code generation), a check should be added. If the address isn't aligned, a SIGBUS signal should be raised. - -Looking at the categories provided: mistranslation, assembly lowering, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor, and others. - -So, what's this about? It's related to how QEMU handles ARM32 instructions during translation. Specifically, the issue is that unaligned accesses aren't being checked as per the documentation. The user wants a check added during translation. - -Mistranslation refers to incorrect mapping from source architecture (like ARM) to the target instruction set or IR. Since this bug is about translating ARM instructions not correctly handling alignment checks, it seems like mistranslation because QEMU isn't properly converting the ARM behavior into the target's (probably TCG or host CPU) operations. - -Alternatively, assembly lowering might refer to generating correct machine code from higher-level IR, but in this case, the issue is more about the translation process not including necessary checks. - -So, I think the main category here is mistranslation because it's an error in how QEMU translates ARM instructions into the target's execution model, specifically missing alignment checks that should be enforced. -</think> - -mistranslation \ No newline at end of file |
