CL 418101 changes Unified IR writer to force mixed tag/case to have common type, emitting the implicit conversion if any of the case values are not assignable to the tag value's type. However, the Go spec definition of equality is non-transitive for channels stored in interfaces, causing incorrect behavior with channel values comparison. To fix it, don't emit the implicit conversions if tag type is channel. Fixes #67190 Change-Id: I9a29d9ce3c7978f0689e9502ba6f15660c763d16 Reviewed-on: https://go-review.googlesource.com/c/go/+/594575 Auto-Submit: Cuong Manh Le <cuong.manhle.vn@gmail.com> Reviewed-by: Keith Randall <khr@google.com> Reviewed-by: Keith Randall <khr@golang.org> LUCI-TryBot-Result: Go LUCI <golang-scoped@luci-project-accounts.iam.gserviceaccount.com> Reviewed-by: Than McIntosh <thanm@google.com> |
