Michael Scire d1f3c4904b kern: fix minor assembly bugs, avoid unnecessary function call in KScheduler hotloop 2021-10-28 19:16:23 -07:00
Michael Scire 92321ccbc8 kern: fix 32-bit light ipc svc handler asm
Nintendo used to do what we were doing because the function wasn't directly in the handler table,
but we've always been directly in the handler table, so we were trashing the last four arguments to light ipc
when called from aarch32. Nothing uses this, but needed to be fixed.

Michael Scire bfffe6b119 kern: devirtualize KAutoObject::DynamicCast<>()
This is an optimization that saves the most common type of virtual call in the kernel (DynamicCast)
by storing class token as a member, rather than getting it via virtual call every time.

This does not currently cost any memory space on 64-bit targets, due to pre-existing padding space.

This optimization can be turned off via a compile-time flag for accuracy.
