You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: zsyscall_aix_ppc.go
    path of file: ./repos/trickster/vendor/golang.org/x/sys/unix
    
    the code of the file until where you have to start completion: // go run mksyscall_aix_ppc.go -aix -tags aix,ppc syscall_aix.go syscall_aix_ppc.go
// Code generated by the command above; see README.md. DO NOT EDIT.

//go:build aix && ppc
