2013-03-12cpu: Replace do_interrupt() by CPUClass::do_interrupt methodAndreas Färber4-3/+10
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 Färber1-3/+1
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>
2013-03-03gen-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.

2013-02-23qemu-log: Remove qemu_log_try_set_file() and its usersPeter Maydell1-2/+0
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 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.

2013-02-16target-microblaze: Move TCG initialization to MicroBlazeCPU initfnAndreas Färber3-8/+12
Split off TCG initialization from cpu_mb_init() into mb_tcg_init() to call it from the initfn. Ensures that a QOM-created MicroBlazeCPU is usable. Signed-off-by: Andreas Färber <afaerber@suse.de>

2013-02-01target-microblaze: Mark as unmigratableAndreas Färber4-14/+10
cpu_{save,load} were no-ops, so de facto it is unmigratable and no backwards compatibility to keep. Therefore mark the MicroBlazeCPU as unmigratable at device level the QOM way and suppress "cpu_common" VMState registration by dropping CPU_SAVE_VERSION.

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. Move common parts of mips cpu_state_reset() to mips_cpu_reset().
