The following patch just removes that part of the comment. 2023-02-08 Jakub Jelinek * tree.def (SAD_EXPR): Remove outdated comment about missing WIDEN_MINUS_EXPR. --- diff --git a/gcc/tree.def b/gcc/tree.def index 087265459b74..e639a039db91 100644 --- a/gcc/tree.def +++ b/gcc/tree.def @@ -1341,8 +1341,7 @@ DEFTREECODE (WIDEN_SUM_EXPR, "widen_sum_expr", tcc_binary, 2) The first two arguments are of type t1 which should be integer. The third argument and the result are of type t2, such that t2 is at least twice the size of t1. Like DOT_PROD_EXPR, SAD_EXPR (arg1,arg2,arg3) is - equivalent to (note we don't have WIDEN_MINUS_EXPR now, but we assume its - behavior is similar to WIDEN_SUM_EXPR): + equivalent to: tmp = WIDEN_MINUS_EXPR (arg1, arg2) tmp2 = ABS_EXPR (tmp) arg3 = PLUS_EXPR (tmp2, arg3)
