I'm enabling framepointer for arm64 port and the work is almost done for linux os.
But I don't have access to darwin_arm64 and can't test and debug the patch on darwin os.
I only have an iPad with arm64 cpu but it's hard for me to get even a shell terminal from it.
Can anyone provide me some suggestions or help?

Hi,
I don't think it's possible to get a shell from an iOS device.
The best way I know of is to run the standard Go tests with iostest.bash. Running GOARCH=arm64 GOOS=darwin go run <go-file> should also work; go uses the exec wrapper in misc/ios/go_darwin_arm_exec.go to sign the binary, copy it to the device and run it through lldb.
iostest.bash and go run need various environment variables that points to your signing provisioning profile. Run misc/ios/detect.go to fetch a set of good values. If you don't have a provisioning profile, running anything from Xcode on your iOS device should set up a profile based on your apple developer account.
Running stuff on iOS is so awful; I'm sorry.

Awesome work!
I do have one if you want me to test something.

You will need a jailbroken device to get shell access.
I do have one handy, so I can test stuff if you want.

Hi Steeve,
Could you please help me test the patch: https://go-review.googlesource.com/c/go/+/61511 on darwin_arm64?
I need the log if it crashes.
Thanks

I'm late to the party but I just tested your CL (from Oct 20th).
Unfortunately it doesn't work, the stack traces are wrong, both in case of a Panic and in case of a nil pointer.
For instance:

Hi,
I ran the golang.org/x/mobile/example/bind/hello/ios example, with this change:
diff --git a/example/bind/hello/hello.go b/example/bind/hello/hello.go
index 2d98ff9..aa25bd3 100644
--- a/example/bind/hello/hello.go

func Greetings(name string) string {
+ crash();
return fmt.Sprintf("Hello, %s!", name)
}
+
+func crash() {
+ var i *int
+ *i = 0
+}
On the darwin/amd64 emulator, the Xcode displayed a good stack trace and pointed at the exact line the program crashed:
On the iPhone 5S, the trace is cut off:
its the same with or without your CL.
If it's any help, if I run the gomobile example after building with -ldflags="-w", the stack trace on the darwin/amd64 emulator regress and look the same as on the iPhone 5S.

@elias
In the case of darwin/amd64, I think what's helping is DWARF, which weirdly is not helping on arm64.
