[Qemu-devel] [PATCH RFC v3 08/21] target-arm: Move CPU feature flags out of CPUState |
|
Date: |
Fri, 3 Feb 2012 03:59:39 +0100 |
The internal CPU feature flags were only ever set in
cpu_reset_model_id(). Therefore move their initialization into
ARMCPUClass. We might want to tweak them in the future though (e.g.,
-cpu cortex-r4,+fpu), so keep a copy in ARMCPU. This in turn means we
need to infer features for both ARMCPUClass and ARMCPU, so move feature
inference to arm_infer_features() and use macros to simplify it.
Since cpu.h defines ARMCPUState, which has been incorporated into
ARMCPU, and tries to use arm_feature() in cpu_get_tb_cpu_state(),
move arm_feature() to cpu-core.h and add a forward declaration.
