Complex types can't be used as method receivers #1716
Description
Test program:
package main
type cplx complex64
func (c cplx) Foo() {}
func main() {
var c cplx
c.Foo()
}
Compiler output:
test.go:5: invalid receiver type cplx
test.go:9: c.Foo undefined (type cplx has no field or method Foo)
The same thing happens with complex128.
I notice in gc/align.c, there's a commented out line that would make
issimple[TCOMPLEX64] and issimple[TCOMPLEX128] true. I'm pretty sure uncommenting that
line would fix this problem, but presumably it was commented out for a reason, so I'll
leave this to someone who knows more about it.
