Update helper to set the throwing location in case of div-by-0.
Cleanup divX.w and add quad word variants of divX.l.
Backports commit 0ccb9c1d8128a020720d5c6abf99a470742a1b94 from qemu
Separate all ccr bits. Continue to batch updates via cc_op.
Signed-off-by: Richard Henderson <rth@twiddle.net>
Fix gen_logic_cc() to really extend the size of the result.
Fix gen_get_ccr(): update cc_op as it is used by the helper.
Factorize flags computing and src/ccr cleanup
Backports commit 620c6cf66584bfbee90db84a7e87a6eabf230ca9 from qemu
Update cc_op directly from tcg_gen_insn_start() and
restore_state_to_opc()
Copied from target-i386
Backports commit 20a8856eba0980fbe9d2b8ed2b33ecdb9c9fe5ad from qemu
Unused function declarations were found using a simple gcc plugin and
manually verified by grepping the sources.

Most of them use guard symbols like CPU_$target_H, but we also have
__MIPS_CPU_H__ and __TRICORE_CPU_H__. They all upset
scripts/clean-header-guards.pl.
The script dislikes CPU_$target_H because they don't match their file
name (they should, to make guard collisions less likely). The others
are reserved identifiers.
Clean them all up: use guard symbol $target_CPU_H for
target-$target/cpu.h.

exec-all.h contains TCG-specific definitions. It is not needed outside
TCG-specific files such as translate.c, exec.c or *helper.c.
One generic function had snuck into include/exec/exec-all.h; move it to
include/qom/cpu.h.
Backports commit 63c915526d6a54a95919ebece83fa9ca631b2508 from qemu
Make M68KCPU an opaque type within cpu-qom.h, and move all definitions of
private methods, as well as all type definitions that require knowledge
of the layout to cpu.h. This helps making files independent of NEED_CPU_H
if they only need to pass around CPU pointers.
Backports commit a836b8fa00fa1032ccd234a71b33943627d211ea from qemu
We are inconsistent with the type of tb->flags: usage varies loosely
between int and uint64_t. Settle to uint32_t everywhere, which is
superior to both: at least one target (aarch64) uses the most significant
bit in the u32, and uint64_t is wasteful.
Compile-tested for all targets.
Backports commit 89fee74a0f066dfd73830a7b5fa137e87888c870 from qemu
The TARGET_HAS_ICE #define is intended to indicate whether a target-*
guest CPU implementation supports the breakpoint handling. However,
all our guest CPUs have that support (the only two which do not
define TARGET_HAS_ICE are unicore32 and openrisc, and in both those
cases the bp support is present and the lack of the #define is just
a bug). So remove the #define entirely: all new guest CPU support
should include breakpoint handling as part of the basic implementation.

The only generic code relying on this is linux-user, but linux users'
default behaviour of defaulting ELF_MACHINE to ELF_ARCH will handle
this.
The machine model bootloaders can just pass EM_68K directly, as that
is architecture specific code.
This removes another architecture specific definition from the global
namespace.
Backports commit 45e6b8b61a7bbb71d1fa6c4193b47ba3a1f9f033 from qemu
This is set to true when the index is for an instruction fetch
translation.
The core get_page_addr_code() sets it, as do the SOFTMMU_CODE_ACCESS
acessors.
All targets ignore it for now, and all other callers pass "false".
This will allow targets who wish to split the mmu index between
instruction and data accesses to do so. A subsequent patch will
do just that for PowerPC.
Backports commit 97ed5ccdee95f0b98bedc601ff979e368583472c from qemu
Remove un-needed usages of ENV_GET_CPU() by converting the APIs to use
CPUState pointers and retrieving the env_ptr as minimally needed.
Scripted conversion for target-* change:
for I in target-*/cpu.h; do
sed -i \
's/\(^int cpu_[^_]*_exec(\)[^ ][^ ]* \*s);$/\1CPUState *cpu);/' \
$I;
done
