cmd/gc: spurious "use of untyped nil" errors '[]arr X nil' and 'uintptr X nil' operations #7206
Description
by carlchatfielduntrusted:
The below two lines will produce "use of untyped nil" errors in addition
to the usual nil conversion error
_ = nil == uintptr(0)
_ = nil == [1]int{}
Doesn't happen for other types
What steps will reproduce the problem?
package main
func main() {
_ = nil == uintptr(0)
_ = nil == [1]int{}
}
http://play.golang.org/p/EPqVqajWRv
What is the expected output?
prog.go:6: cannot convert nil to type uintptr
prog.go:7: cannot convert nil to type [1]int
What do you see instead?
prog.go:6: cannot convert nil to type uintptr
prog.go:6: use of untyped nil
prog.go:7: cannot convert nil to type [1]int
prog.go:7: use of untyped nil
