[M3devel] deeper meaning of in_memory?

[Jay K]

In M3CG, what is the deeper meaning of in_memory?I know it means -- "put the thing in memory".But why and exactly what?
Presumably it can also be in a register, just that the in-memory value must be kept up to date.Like, stores should be volatile, but reads don't have to be?Does it mean the value will be used in an exception/finally handler?Maybe reads do need to be volatile? Maybe it is accessed by another thread w/o a lock?

If I take the address of something, is that good enough?

I should just look where m3front uses it, I know.For now I'll probably take it to mean "volatile".I already mark all structs as volatile. But I don't make everything volatile (like how m3cc long did).

Thanks, - Jay
