[Qemu-devel] [RFC qom-cpu 38/41] target-lm32: Move features field from C


From: Andreas Färber
Subject: [Qemu-devel] [RFC qom-cpu 38/41] target-lm32: Move features field from CPULM32State to LM32CPU
Date: Wed, 4 Sep 2013 11:05:18 +0200

This simplifies the code after conversion to DisasContext::cpu.
