Hi,
Recently I encountered a problem which seems to be related to SSA
optimization
and feels hard to figure out what some SSA operation means.
Code:
case1:
func main() {
var x int
go func() {
for {
x++ //no matter "-N" compile flags is specified or
not,
Thank you Keith for clarification. It's really of great help.

calls,
and I'm not sure if it will happen in this case(f() and o.done has no

with each other so it is possible?).
If anyone knows I would appreciate for your clarification.
Thanks for your time.

Thank you Jan, sorry for my bad english.
Do you mean in following case if anthoer goroutine is observing A and B,
there is no possbility that A is 0 and B is 5? (assuming no other
synchronization here)
```
var A, B int
func try() {
defer func() { B = 5 }
A = 3
}

Thanks Jan and Axel, I may need to figure out go memory model and hardware
memory model.

at any time, which means for different pc there maybe lot of possiblites
of stack maps.
Thanks
