The user is talking about QEMU not checking for unaligned data access in ARM32 instructions. They mentioned specific instructions like LDRD, STRD, LDREX, STREX which should require alignment according to ARM documentation. The example given is that an LDRD instruction at VA 0x10240 is accessing an unaligned address, but QEMU allows it without raising an alignment fault. The user says that QEMU 5.1.0 doesn't handle this correctly and suggests that a patch should raise a SIGBUS during translation when an unaligned address is detected. + +So, the problem is about the instruction execution not adhering to alignment requirements. The key here is that the ARM architecture specifies certain instructions must have aligned addresses, and QEMU isn't enforcing that. The bug is in how the instructions are handled during execution, which would be part of the instruction processing in QEMU. The user is pointing out that the translation process (tcg) should include a check for alignment. + +The categories to choose from are instruction, syscall, or runtime. Since this is about the correct handling of specific instructions (LDRD, etc.) and their alignment checks, which are part of the instruction execution semantics, this falls under the "instruction" category. It's not a syscall issue because it's about CPU instructions rather than system calls. It's also not a general runtime error but a specific instruction behavior problem. +</think> + +instruction \ No newline at end of file |
