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.

It was never implemented. Signed-off-by: Andreas Färber <afaerber@suse.de>
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. Move common parts of mips cpu_state_reset() to mips_cpu_reset().
