The compiler incorrectly will error when comparing a nil pointer
interface to a nil pointer of any other type. Example:
(*int)(nil) == interface{}(nil)
Will error with "gc: illegal constant expression: *int == interface {}"

cmd/compile: allow huge rsh in constants arithmetic 2015-08-21T20:27:22+00:00 Alberto Donizetti alb.donizetti@gmail.com 2015-08-20T15:53:41+00:00 85de30e72f62c41f21eb1eb2c8ad4a05a163c9c1 Currently an expression like var v = 0 >> 1000 is rejected by gc with a "stupid shift" error, while gotype compiles it successfully.

exp/ssa/interp: (#6 of 5): test interpretation of SSA form of $GOROOT/test/*.go. 2013-02-21T17:48:38+00:00 Alan Donovan adonovan@google.com 2013-02-21T17:48:38+00:00 aa5aaabb0d18d21d97e9c98d7dfde4899a498335 The interpreter's os.Exit now triggers a special panic rather than kill the test process. (It's semantically dubious, since it will run deferred routines.) Interpret now returns its exit code rather than calling os.Exit. Also: - disabled parts of a few $GOROOT/tests via os.Getenv("GOSSAINTERP"). - remove unnecessary 'slots' param to external functions; they are never closures. Most of the tests are disabled until go/types supports shifts. They can be reenabled if you patch this workaround: https://golang.org/cl/7312068 R=iant, bradfitz CC=golang-dev, gri https://golang.org/cl/7313062
