Josh Bleecher Snyder e00e57d67c cmd/compile: ignore all unreachable values during simple phi insertion ... Simple phi insertion already had a heuristic to check for dead blocks, namely having no predecessors. When we stopped generating code for dead blocks, we eliminated some values contained in more subtle dead blocks, which confused phi insertion. Compensate by beefing up the reachability check. Fixes #19678 Change-Id: I0081e4a46f7ce2f69b131a34a0553874a0cb373e Reviewed-on: https://go-review.googlesource.com/38602 Run-TryBot: Josh Bleecher Snyder <josharian@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Keith Randall <khr@golang.org>		2017-03-24 18:00:15 +00:00
