[M3devel] processing stack/context

[Jay K]

Tony, it looks like you assume the context passed to a signal handler is on the stack.

Is that really guaranteed? It couldn't be in some thread local for some reason?

 (signals can nest? Therefore that would be problematic?)

We can just use the address of a local, right?

 

And we can assume the signal stack is the regular stack?

By default?

(I know sigstack/sigaltstack can fiddle with it; we should assume it isn't used.)

 

I noticed this in structure ThreadWin32.m3 a bit more like ThreadPosix.m3.
