2013-03-12cpu: Replace do_interrupt() by CPUClass::do_interrupt methodAndreas Färber
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 Färber
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-cris/helper.c: Update Coding StyleAndreas Färber
Reindent, add missing braces and drop/adjust whitespace. Prepares for CPUArchState-to-CPUState field movements in cpu_cris_handle_mmu_fault(), do_interruptv10() and do_interrupt(). The remaining functions were so minor that they can be fixed in one go. Acked-by: Edgar E. Iglesias <edgar.iglesias@gmail.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-03-03gen-icount.h: Rename gen_icount_start/end to gen_tb_start/endPeter Maydell
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 Färber
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.

2013-02-23qemu-log: Remove qemu_log_try_set_file() and its usersPeter Maydell
Remove the function qemu_log_try_set_file() and its users (which are all in TCG code generation functions for various targets). This function was added to abstract out code which was originally written as "if (!logfile) logfile = stderr;" in order that BUG: case code which did an unguarded "fprintf(logfile, ...)" would not crash if debug logging was not enabled. Since those direct uses of logfile have also been abstracted away into qemu_log() calls which check for a NULL logfile, there is no need for the target-* files to mess with the user's chosen logging settings.

2013-02-16cpu: Add CPUArchState pointer to CPUStateAndreas Färber
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.

2013-02-16target-cris: Introduce CRISCPU subclassesAndreas Färber
Use class_init functions to initialize the VR in preparation for overriding v32+ behavior there. Move cpu_cris_init() to cpu.c and hook up a class_by_name callback. This change leads to unknown -cpu model names no longer falling back to a CPU with VR 32 but instead returning NULL. Acked-by: Edgar E. Iglesias <edgar.iglesias@gmail.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-02-16target-cris: Move TCG initialization to CRISCPU initfnAndreas Färber
Split out TCG initialization from cpu_cris_init(). Avoid CPUCRISState dependency for v10-specific initialization and for non-v10 by inlining the decision into the initfn as well. Signed-off-by: Andreas Färber <afaerber@suse.de>

2013-01-15cpu: Move cpu_index field to CPUStateAndreas Färber
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.
