From cc6dfecf02eadbdc14100dff54aec4df0c139393 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Tue, 12 Jan 2010 19:59:34 +0000 Subject: tcg-sparc: Implement ext32[su]_i64 The 32-bit right-shift instructions is defined to extend the shifted output to 64-bits. A shift count of zero therefore is a simple extension without actually shifting.
