The user is using qemu-ppc64le version 2.12.0 on an x86_64 Arch Linux host. They're working on VSX support in libVPX and encountered an "uncaught target signal 4 (Illegal instruction)" when changing vec_sub to vec_subs in their code. The backtrace points to a SIGILL in QEMU's cpu_loop, specifically at line 723 of loopfilter_vsx.c. + +First, the error is an Illegal Instruction (SIGILL), which usually means the CPU tried to execute an instruction it doesn't recognize. Since they're using QEMU to emulate a PowerPC 64-bit little-endian environment, the problem might be related to how QEMU handles certain instructions. + +The user mentions that the issue doesn't occur on a real POWER9 machine. That suggests that the code itself is correct for the actual hardware, but QEMU might not be properly emulating a specific instruction. The change from vec_sub to vec_subs likely introduces an instruction that QEMU's emulator either doesn't recognize or isn't handling correctly. + +Since the error is an illegal instruction within QEMU's process, and given that QEMU is responsible for translating or emulating the guest instructions, this seems like an issue with QEMU's instruction handling. The categories given are 'instruction', 'syscall', or 'runtime'. The 'instruction' category is for faulty instructions in the bug report, which fits here because the problem arises from QEMU not handling a specific instruction (vec_subs) correctly. The 'syscall' category is for system call errors, which doesn't apply here. 'Runtime' is for other runtime errors, but since the core issue is about the instruction emulation, 'instruction' makes sense. + +So, the correct category should be 'instruction'. +</think> + +instruction \ No newline at end of file |
