Your current stash database is schema version <strong>{{.ExistingVersion}}</strong> and needs to be migrated to version <strong>{{.MigrateVersion}}</strong>.
This version of Stash will not function without migrating the database. <strong>The schema migration process is not reversible. Once the migration is
performed, your database will be incompatible with previous versions of stash.</strong>

This program reads a file containing function prototypes

The prototypes are marked by lines beginning with "//sys"

* The parameter lists must give a name for each argument.
This includes return parameters.
* The parameter lists must give a type for each argument:
the (x, y, z int) shorthand is not allowed.
* If the return parameter is an error number, it must be named errno.
A line beginning with //sysnb is like //sys, except that the
goroutine will not be suspended during the execution of the system
call. This must only be used for system calls which can never
block, as otherwise the system call could cause all goroutines to
hang.

- zsyscall_aix_ppc64_gc.go: gc part with //go_cgo_import_dynamic and a call to syscall6
- zsyscall_aix_ppc64_gccgo.go: gccgo part with C function and conversion to C type.

This program reads a file containing function prototypes
(like syscall_solaris.go) and generates system call bodies.
The prototypes are marked by lines beginning with "//sys"
and read like func declarations if //sys is replaced by func, but:
* The parameter lists must give a name for each argument.
This includes return parameters.
* The parameter lists must give a type for each argument:
the (x, y, z int) shorthand is not allowed.
* If the return parameter is an error number, it must be named err.
* If go func name needs to be different than its libc name,
* or the function is not in libc, name could be specified
* at the end, after "=" sign, like
//sys getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
