2014-03-17target-alpha: fix subl and s8subl indentationPaolo Bonzini
Two missing braces, one close and one open, fabulously let the code compile. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-03-13cpu: Move breakpoints field from CPU_COMMON to CPUStateAndreas Färber
Most targets were using offsetof(CPUFooState, breakpoints) to determine how much of CPUFooState to clear on reset. Use the next field after CPU_COMMON instead, if any, or sizeof(CPUFooState) otherwise. Signed-off-by: Andreas Färber <afaerber@suse.de>

2013-10-12target-alpha: Convert to new ldst opcodesRichard Henderson
Or, partially. The fundamental primitives for the port are gen_load_mem and gen_store_mem, which take a callback to emit the memory operation. For that, we continue to use the original inline functions that forward to the new ops, rather than replicate the same thing privately. That said, all free-standing calls to tcg_gen_qemu_* have been converted. The 32-bit floating-point references now use _i32 opcodes, eliminating a truncate or extension.

2013-10-10tcg: Move helper registration into tcg_context_initRichard Henderson
No longer needs to be done on a per-target basis. Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-08-16target-alpha: Consider the superpage when threading and ending TBsRichard Henderson
This allows significantly more threading, and occasionally larger TBs, when processing code for the kernel and PALcode. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-08-16target-alpha: Use goto_tb in call_palRichard Henderson
With appropriate flushing when the PALBR changes, the target of a CALL_PAL is so predictable we can chain to it. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-08-16target-alpha: Implement call_pal without an exceptionRichard Henderson
The destination of the call_pal, and the cpu state, is very predictable; there's no need for exiting the cpu loop. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-07-23cpu: Move singlestep_enabled field from CPU_COMMON to CPUStateAndreas Färber
Prepares for changing cpu_single_step() argument to CPUState. Acked-by: Michael Walle <michael@walle.cc> (for lm32) Signed-off-by: Andreas Färber <afaerber@suse.de>

2013-07-18target-alpha: Move alarm to vm_clockRichard Henderson
Basing the alarm off the rtc_clock was silly. It leads to horrible spinning in the guest after being suspended and resumed, as it tries to catch up with lost ticks. This requires adding an accessor for reading the vm_clock too. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-07-09target-alpha: Change gen_intermediate_code_internal() argument to AlphaCPUAndreas Färber
Also use bool argument while at it. Prepares for moving singlestep_enabled field to CPUState. Reviewed-by: Richard Henderson <rth@twiddle.net> 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>
2013-03-03gen-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.

2013-01-15cpu: 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().
