Hi,
Regarding address spaces, I saw that there is a pass to remove address
space casts. But if I generate IR using `*llvm-goc -dump-ir -enable-gc=1
test.go*` for the following go file, I still can see the *addrspacecast*
instruction. What is the reason to see that *addrspacecast? *I feel that
pass is not running. Can you help me to understand this problem?
*package main*
*func main() {*
* _ = stackIt2()*
*}*
*//go:noinline*
*func stackIt2() *int {*
* y := 2*
* res := y * 2*
* return &res*
*}*
Thank you,
Kavindu
