2013-03-12target-sh4: Introduce SuperHCPU subclassesAndreas Färber
Store legacy name in SuperHCPUClass for -cpu ? and for case-insensitive class lookup. List CPUs by iterating over TYPE_SUPERH_CPU subclasses. 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.

2013-02-16cpu: 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.

2013-01-15cpu: 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().

2012-10-28target-sh4: rename helper flagsAurelien Jarno
Rename helper flags to the new ones. This is purely a mechanical change, it's possible to use better flags by looking at the helpers. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
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.

2012-09-21target-sh4: cleanup DisasContextAurelien Jarno

2012-09-21target-sh4: rework exceptions handlingAurelien Jarno
Since commit fd4bab102 PC is restored in case of exception through code retranslation. While it is clearly the thing to do in case it is not not known if an helper is going to trigger an exception or not (e.g. for load/store, FPU, etc.), it just make things slower when the exception is already known at translation time. Partially revert this commit and save PC in the TCG code. Set bstate to BS_BRANCH to not generate TCG exit code. Micro-optimize the sleep helper. Make all the exception helpers to call raise_exception and mark it as noreturn. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-09-21target-sh4: remove gen_clr_t() and gen_set_t()Aurelien Jarno

2012-09-21target-sh4: optimize swap.wAurelien Jarno
It's possible swap the two 16-bit words of a 32-bit register using a rotation. If the TCG target doesn't implement rotation, the replacement code is similar to the previously implemented code. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-09-21target-sh4: optimize xtrctAurelien Jarno

2012-09-21target-sh4: implement addv and subv using TCGAurelien Jarno

2012-06-04Kill off cpu_state_reset()Andreas Färber
In commit 1bba0dc932e8826a7d030df3767daf0bc339f9a2 cpu_reset() was renamed to cpu_state_reset(), to allow introducing a new cpu_reset() that would operate on QOM objects. All callers have been updated except for one in target-mips, so drop all implementations except for the one in target-mips and move the declaration there until MIPSCPU reset can be fully QOM'ified.

2012-01-10target-sh4: ignore ocbp and ocbwb instructionsAurelien Jarno
ocbp and ocbwb controls the writeback of a cache line to memory. They are supposed to do nothing in case of a cache miss. Given QEMU only partially emulate caches, it is safe to ignore these instructions. This fixes a kernel oops when trying to access an rtl8139 NIC with recent versions.
