make(T, n, m) returns a slice of type T with length n and capacity m where "The size arguments n and m must be of integer type or untyped." https://tip.golang.org/ref/spec#Making_slices_maps_and_channels The failure to reject typed non-integer size arguments in make during compile time was uncovered after https://golang.org/cl/27851 changed the generation of makeslice calls. Fixes #16940 Updates #16949 Change-Id: Ib1e3576f0e6ad199c9b16b7a50c2db81290c63b4 Reviewed-on: https://go-review.googlesource.com/28301 Reviewed-by: Joe Tsai <thebrokentoaster@gmail.com> Reviewed-by: Josh Bleecher Snyder <josharian@gmail.com>
