Russ Cox	7e84666df1	gc: clearer error for struct == struct ... cmp6.go:48: invalid operation: t3 == t3 (operator == not defined on struct) Fixes #1438. R=ken2 CC=golang-dev https://golang.org/cl/4003045	2011-01-21 18:15:59 -05:00
Russ Cox	23bd214aee	gc: implement new comparison rule ... The new comparison rule was added to the spec by changeset: 5605:33abb649cb63 user: Robert Griesemer <gri@golang.org> date: Thu Jun 03 16:55:50 2010 -0700 files: doc/go_spec.html description: go spec: Base comparison compatibility on assignment compatibility. Specifically: - Simplified definition of comparison compatibility and folded into section on comparison operators since it's only used there. This is a small language change/cleanup. As a consequence: - An interface value may now be compared against a non-interface value. - Channels with opposite directions cannot be compared directly anymore (per discussion with rsc).
