From 53f6672bcf57d82b794a2cc3a3469be7d35c8653 Mon Sep 17 00:00:00 2001 From: "Emilio G. Cota" Date: Fri, 16 Jun 2017 14:56:37 -0400 Subject: [PATCH] gen-icount: use tcg_ctx.tcg_env instead of cpu_env We are relying on cpu_env being defined as a global, yet most targets (i.e. all but arm/a64) have it defined as a local variable. Luckily all of them use the same "cpu_env" name, but really compilation shouldn't break if the name of that local variable changed. Fix it by using tcg_ctx.tcg_env, which all targets set in their translate_init function. This change also helps paving the way for the upcoming "translation loop common to all targets" work.
