From a768e4e99247911f00c5c0267c12d4e207d5f6cc Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Mon, 21 Nov 2016 11:13:39 +0100 Subject: tcg: Add opcode for ctpop MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The number of actual invocations of ctpop itself does not warrent an opcode, but it is very helpful for POWER7 to use in generating an expansion for ctz.
