From 5790c1648d48e3e659f75cc582c32054ba0eb23c Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Wed, 12 Jun 2019 11:55:42 -0400 Subject: [PATCH] target/mips: Use env_cpu, env_archcpu Cleanup in the boilerplate that each target must define. Replace mips_env_get_cpu with env_archcpu. The combination CPU(mips_env_get_cpu) should have used ENV_GET_CPU to begin; use env_cpu now.
