Hello,
I am working on server-side webassembly stuff and the fact that I am not a
javascript interpreter was getting in the way due to nearly all the
standard library pulling in syscall/js. To obviate this problem, I have
created a custom GOOS that I will not link any javascript code to. I have
been having a strange issue when trying to test a "Hello world" program via
this
fork: https://github.com/Xe/go/commit/37bc30ec064a32a630cdad325f83020c1f5be976
The program in question:
// main.go
package main
func main() {
println("hello, world!")
}
Yields this error
~/Code/godagger/bin $ GOOS=dagger GOARCH=wasm ./go build -o main.wasm -v -x
main.go

In a failed attempt to debug this further, I have added some debugging calls to
that part of the linker and gotten this information:

I tried skipping over this block of code in the linker, but that produced an
obviously wrong binary output (less than 1024 bytes).
What did I do wrong?
