Abort evconst if its argument isn't a Go constant. The SSA backend will do the optimizations in question later. They tend to be weird cases, like uintptr(unsafe.Pointer(uintptr(1))). Fix OADDSTR and OCOMPLEX cases in isGoConst. OADDSTR has its arguments in n.List, not n.Left and n.Right. OCOMPLEX might have a 2-result function as its arg in List[0] (in which case it isn't a Go constant). Fixes #24760 Change-Id: Iab312d994240d99b3f69bfb33a443607e872b01d Reviewed-on: https://go-review.googlesource.com/c/151338 Run-TryBot: Keith Randall <khr@golang.org> Reviewed-by: Matthew Dempsky <mdempsky@google.com> TryBot-Result: Gobot Gobot <gobot@golang.org>
