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