The user is talking about a problem in QEMU where a SIGILL (illegal instruction) occurs when running glxgears on ppc64le. They mentioned that the issue is related to constant folding on 64-bit subtraction causing a bad shift instruction. The problem arises because a shift instruction ends up with a -1 shift count, leading to an invalid instruction. + +First, the categories to choose from are instruction, syscall, or runtime. The bug is caused by the code generation part of QEMU, specifically in the translator (translate.c). The user found that when constant folding is applied to subtraction, it leads to an invalid instruction being generated. The root cause seems to be in the translation phase where the optimizer is generating incorrect machine code due to a shift with an invalid immediate value. + +The error is not a system call (syscall) since the issue is in the generated machine code. It's not a runtime error in the general sense but rather an error in the instruction generation. However, the problem is that the instruction generated is invalid, leading to a SIGILL at runtime. But the classification options are instruction, syscall, runtime. + +The instruction category refers to a faulty instruction being described. Since the problem is that the optimizer is generating an invalid instruction (RLDICL with c=-1 leading to an invalid opcode), this seems to fit the "instruction" category. The error is in the instruction generation process. Even though it's caught at runtime as a SIGILL, the root cause is the incorrect instruction generated by the code, so the category should be "instruction". +</think> + +instruction \ No newline at end of file |
