2021-03-29[syserror] Split usermem packageZach Koopmans
Split usermem package to help remove syserror dependency in go_marshal. New hostarch package contains code not dependent on syserror. PiperOrigin-RevId: 365651233
2020-09-29Replace remaining uses of reflection-based marshalling.Rahat Mahmood
- Rewrite arch.Stack.{Push,Pop}. For the most part, stack now implements marshal.CopyContext and can be used as the target of marshal operations. Stack.Push had some extra logic for automatically null-terminating slices. This was only used for two specific types of slices, and is now handled explicitly. - Delete usermem.CopyObject{In,Out}. - Replace most remaining uses of the encoding/binary package with go-marshal. Most of these were using the binary package to compute the size of a struct, which go-marshal can directly replace. ~3 uses of the binary package remain. These aren't reasonably replaceable by go-marshal: for example one use is to construct the syscall trampoline for systrap. - Fill out remaining convenience wrappers in the primitive package.

2020-09-16Rename marshal.Task to marshal.CopyContext.Rahat Mahmood
CopyContext is a better name for the interface because from go-marshal's perspective, the interface has nothing to do with a task. A kernel.Task happens to implement the interface, but so can other things like MemoryManager and IO sequences. PiperOrigin-RevId: 331959678
