2013-04-08hw: move headers to include/Paolo Bonzini1-1/+1
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.

2013-03-12cpu: Replace do_interrupt() by CPUClass::do_interrupt methodAndreas Färber4-5/+11
This removes a global per-target function and thus takes us one step closer to compiling multiple targets into one executable. It will also allow to override the interrupt handling for certain CPU families. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-03-12cpu: Move halted and interrupt_request fields to CPUStateAndreas Färber3-6/+7
Both fields are used in VMState, thus need to be moved together. Explicitly zero them on reset since they were located before breakpoints. Pass PowerPCCPU to kvmppc_handle_halt(). Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-03-12target-sh4: Move PVR/PRR/CVR into SuperHCPUClassAndreas Färber3-12/+15
They are never changed once initialized, and moving them to the class will allow to inspect them before instantiating. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-03-12target-sh4: Introduce SuperHCPU subclassesAndreas Färber3-85/+186
Store legacy name in SuperHCPUClass for -cpu ? and for case-insensitive class lookup. List CPUs by iterating over TYPE_SUPERH_CPU subclasses. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-03-03gen-icount.h: Rename gen_icount_start/end to gen_tb_start/endPeter Maydell1-2/+2
The gen_icount_start/end functions are now somewhat misnamed since they are useful for generic "start/end of TB" code, used for more than just icount. Rename them to gen_tb_start/end.

2013-03-03cpu: Introduce ENV_OFFSET macrosAndreas Färber1-0/+1
Introduce ENV_OFFSET macros which can be used in non-target-specific code that needs to generate TCG instructions which reference CPUState fields given the cpu_env register that TCG targets set up with a pointer to the CPUArchState struct.

2013-02-16cpu: Add CPUArchState pointer to CPUStateAndreas Färber1-0/+2
The target-specific ENV_GET_CPU() macros have allowed us to navigate from CPUArchState to CPUState. The reverse direction was not supported. Avoid introducing CPU_GET_ENV() macros by initializing an untyped pointer that is initialized in derived instance_init functions. The field may not be called "env" due to it being poisoned.

2013-01-15cpu: Move cpu_index field to CPUStateAndreas Färber1-1/+1
Note that target-alpha accesses this field from TCG, now using a negative offset. Therefore the field is placed last in CPUState. Pass PowerPCCPU to [kvm]ppc_fixup_cpu() to facilitate this change.

2012-09-21target-sh4: rework exceptions handlingAurelien Jarno3-30/+32
Since commit fd4bab102 PC is restored in case of exception through code retranslation. While it is clearly the thing to do in case it is not not known if an helper is going to trigger an exception or not (e.g. for load/store, FPU, etc.), it just make things slower when the exception is already known at translation time. Partially revert this commit and save PC in the TCG code. Set bstate to BS_BRANCH to not generate TCG exit code. Micro-optimize the sleep helper. Make all the exception helpers to call raise_exception and mark it as noreturn. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

In commit 1bba0dc932e8826a7d030df3767daf0bc339f9a2 cpu_reset() was renamed to cpu_state_reset(), to allow introducing a new cpu_reset() that would operate on QOM objects.
