From 13a0f7b50299f9ab40dad7c855539af65e34d132 Mon Sep 17 00:00:00 2001 From: nobishino Date: Tue, 16 Mar 2021 19:49:13 +0000 Subject: [PATCH] spec: clarify that signed integers>=0 are permitted as shift counts In Go1.13 and above, signed integers are permitted as shift counts as long as they are >=0. However, the comments in the "Arithmetic operators" section says shift operators accept "unsigned integer" as of right operands. Replacing this with "integer>=0" resolves the misunderstanding that shift operators permit only unsigned integers.
