LLVM ERROR: Coroutines cannot handle non static allocas yet

[maxn0d3x]

First of all, because normal Go generates super big size wasm bundle, I wanted to use tinygo .

I tried to run and test wasm bundling using the following example(in https://github.com/golang/go/wiki/WebAssembly) of

https://github.com/bobcob7/wasm-rotating-cube

Because I am using MacOS and cannot install llvm and tinygo(I couldn't install),
I ran tinygo inside docker container. However, although This is pretty very basic example, I got this error!? Did I something wrong? or tinygo hasn't support it yet?

Looks like this feature is not yet fully implemented. Tagging as such.

This error is caused by a limitation in the coroutine support of LLVM, not in TinyGo (although TinyGo might be able to fix some of it). I'm surprised to see it, because I thought most of those issues were gone now.
Looking at the code, it also relies on js.NewCallback which is not yet supported.

After #828, there should not be any generated non-static allocas left.

That's right. I believe this bug has been fixed now and there is testing in place to avoid future recurrences (see #774). Please comment if there are still instances of it left.

The old coroutines implementation does still split allocas sometimes I think, so yes there may still be some issues. The new implementation does not.
