21 * General notes about mono-context.
22 * Each arch defines a MonoContext struct with all GPR regs + IP/PC.
23 * IP/PC should be the last element of the struct (this is a mild sgen constraint we could drop if needed)
24 * Macros to get/set BP, SP and IP are defined too.
25 * MONO_CONTEXT_GET_CURRENT captures the current context as close as possible. One reg might be clobbered
26 * to hold the address of the target MonoContext. It will be a caller save one, so should not be a problem.
