Hi everybody,

I was going through the Go memory model at https://golang.org/ref/mem

In the second line,first paragraph of Happens Before Description it is 
written that  

* compilers and processors may reorder the reads and writes executed within 
a single goroutine only when the reordering does not change the behavior 
within that goroutine as defined by the language specification.

I wanted to ask about what are the rules for read and writes reordering 
within a goroutine defined by the language specification.

Happens before relation define rules on reads and writes on the same 
variable only, are there any rules in language specification for reads and 
writes on different variables that may be reordered by processor or compiler

Thanks in advance.


Regards
Arpit
