From 9593a3988c3e788790aa107d778386b09f456a6d Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 16 Jun 2020 10:32:25 +0100 Subject: [PATCH] target/arm: Fix missing temp frees in do_vshll_2sh MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The widenfn() in do_vshll_2sh() does not free the input 32-bit TCGv, so we need to do this in the calling code.
