The user is reporting a regression in QEMU when upgrading from version 2.7 to 2.8, and it's still present in 2.10.1. The problem occurs during GCC validation, specifically with test cases involving atomics. They provided an example executable, atomic-exchange-4.exe, which works in 2.7 but crashes in later versions with a signal 6 (Aborted), leading to a core dump. + +Looking at the details, the user ran the executable with qemu-armeb and noticed a difference in the instruction trace. The specific instruction mentioned is "addls pc, pc, r3, lsl #2" at address 0x40a17790. The next address differs between QEMU 2.7 and 2.10.1, which suggests that the emulator is executing different instructions or handling them differently after that point. + +The key part here is the instruction execution. The "addls" instruction is a conditional add (execute if Lower or Same, i.e., Z flag set). The fact that the next address differs implies that the emulator's handling of this instruction might be incorrect in the newer versions. Since the problem is related to how the instruction is executed (leading to an abort), this points towards an instruction-level issue. The user also mentioned that the problem is in the startup code, specifically in _dl_sysdep_start, which is part of the dynamic linker. However, the core issue seems to be the execution of the "addls" instruction, leading to incorrect program flow. + +The error isn't about a system call (which would fall under syscall), nor is it a general runtime error like memory management or threading issues. The problem is directly tied to how a specific ARM instruction is emulated. Therefore, the correct category here is "instruction". +</think> + +instruction \ No newline at end of file |
