From ba7d3d1858c257e39b47f7f12fa2016ffd960b11 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Alex=20Benn=C3=A9e?= Date: Thu, 12 Jan 2017 15:02:50 +0000 Subject: [PATCH] cpu_common_reset: wrap TCG specific code in tcg_enabled() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Both the cpu->tb_jmp_cache and SoftMMU TLB structures are only used when running TCG code so we might as well skip them for anything else.
