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. Move common parts of mips cpu_state_reset() to mips_cpu_reset(). Acked-by: Richard Henderson <rth@twiddle.net> (for alpha) [AF: Rebased onto ppc CPU subclasses and openpic changes] Signed-off-by: Andreas Färber <afaerber@suse.de>

2012-10-30target-sparc: Revert setting cpu_dst to gen_dest_gprRichard Henderson
There is some read-after-write error within the OP=2 insns which prevents setting cpu_dst to the real output register. Until this is found and fixed, always write to a temporary first.

2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr.

2012-10-20target-sparc: Remove cpu_tmp0 as a globalRichard Henderson
Subroutines do their own local temporary management. Within disas_sparc_insn we limit the existance of the variable to OP=2 insns, and delay initialization as late as is reasonable for the specific XOP.

2012-10-13target-sparc: Don't compute full flags value so oftenRichard Henderson
