- set correct position for closure capture variable in (*irgen).use() (issue20250.go) Also, evaluate rhs, lhs in that order in assignment statements to match noder1 (affects ordering of closure variables). - make sure to set Assign flag properly in (*irgen).forStmt() for range variables which are map accesses (issue9691.go) - make sure CheckSize() is call on the base type for top-level types converted by (*irgen).typ() that are pointer types (issue20174.go and issue37837.go) - deal with parentheses properly in validation function (*irgen).validate() (issue17270.go) - avoid HasNil call on type TTYPEPARAM - types2 typechecker will have already checked validity of the typeparam having nil value (new test issue39755.go) Change-Id: Ie68004d964698aea047e19e7dcd79b297e9d47ca Reviewed-on: https://go-review.googlesource.com/c/go/+/334733 Trust: Dan Scales <danscales@google.com> Run-TryBot: Dan Scales <danscales@google.com> TryBot-Result: Go Bot <gobot@golang.org> Reviewed-by: Keith Randall <khr@golang.org>
