On powerpc64le, Linux indicates success or failure using `cr0.SO` rather -//! than by returning a negative error code as most other architectures do. In -//! theory we could immediately translate this into a `Result`, and it'd save a -//! few branches. And in theory we could have specialized sequences for use -//! with syscalls that are known to never fail. However, those would require -//! more extensive changes in rustix's platform-independent code. For now, we -//! check the flag and negate the error value to make PowerPC64 look like other -//! architectures. - -use crate::backend::reg::{ - ArgReg, FromAsm, RetReg, SyscallNumber, ToAsm, A0, A1, A2, A3, A4, A5, R0, -};
