Steps to build the changes:

1. Make changes to the files in "arch/s390x" repo...
2. Do a "git push" of local branch changes to here.. git push git@github.com:Vishwanatha-HD/arch.git...
3. Edit the "src/cmd/internal/disasm/disasm.go" file to add "github.com:Vishwanatha-HD/arch/s390x/s390xasm" as an import path..
4. From "src/cmd" directory, get the latest changes of the github.com/arch repo by executing "go get github.com/Vishwanatha-HD/arch@<latest_commit_id>" cmd...
5. Execute "go mod tidy" command from "src/cmd" directory.. This will update the go.mod file with the github.com/arch repo with the latest commit hash..
6. Execute "go mod vendor" command from "src/cmd/objdump" directory...
7. Execute "go clean" and "go build" commands..
8. This will create a "objdump" binary inside "src/cmd/objdump" directory..
9. Execute "go clean", "go build" and "go test -c" commands from "arch/s390x/s390xasm" directory to build the local changes & create a s390xasm.test file..
10. Use the "objdump" binary which is locally built inside "src/cmd/objdump" to disassemble the s390xasm.test file.. For eg..
11. Execute the following command.. "/home/vishwa/golang/go/src/cmd/objdump/objdump -gnu s390xasm.test > <txt_file>"
12. The new "txt_file" created will have the latest changes done to "arch/s390x/s390xasm" directory...
