[go-nuts] how gollvm produces a project llvm-ir

[ZHOU PERTER]

Hi,
i want to use gollvm to produces a project llvm-ir
i use `go build -work -x . 1> transcript.txt 2>&1` and `egrep 
'(WORK=|llvm-goc -c)' transcript.txt`
to ever `llvm-goc -c` command add `-S -emit-llvm` to produces .ll for each 
.go file
then i use https://github.com/llir/llvm to transfer llvm ir to go build-in 
struct,but llir only parse one file 
for simple file it's ok
```
package main
import (
    "fmt"
)
func main(){
    a := "hello_world"
    fmt.Println(a)
}
but for multiple packages project the error `unable to locate ParamAttr 
enum corresponding to "noundef"` occur when i only provide main.ll。
any way to merger mutli .ll to one .ll or other method so that  i can do 
multiple 
packages project data flow analysis?
Thankss,
PERTER
