This is improved type checking for the translators -- it's no longer
possible to accidentally swap arguments to the branch functions.
Note that the code generating backends still manipulate labels as int.
With notable exceptions, the scope of the change is just a few lines
for each target, so it's not worth building extra machinery to do this
change in per-target increments.

Instead of using the _raw family of ld/st accessor functions, use
cpu_*_data. All this code is CONFIG_USER_ONLY, so the two are the
same semantically, but the _raw functions are really a detail of
the implementation which has leaked into a few callsites like this one.

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.

mips_cpu_handle_mmu_fault pc a080cd80 ad b80003fd rw 0 mmu_idx 0
So it's very difficult to find LOG_UNIMP message.
The mips_cpu_handle_mmu_fault() messages appear on enabling ANY

Adding separate log category for *_cpu_handle_mmu_fault()
logging fixes the problem.

The LEON3 processor has support for the CASA instruction which is
normally only available for SPARC V9 processors. Binutils 2.24
and GCC 4.9 will support this instruction for LEON3. GCC uses it to
generate C11 atomic operations.
The CAS synthetic instruction uses an ASI of 0x80. If TARGET_SPARC64 is
not defined use a supervisor data load/store for an ASI of 0x80 in
helper_ld_asi()/helper_st_asi(). The supervisor data load/store was
choosen according to the LEON3 documentation.
The ASI 0x80 is defined in the SPARC V9 manual, Table 12—Address Space
Identifiers (ASIs). Here we have: 0x80, ASI_PRIMARY, Unrestricted
access, Primary address space.
Tested with the following program:
#include <assert.h>
#include <stdatomic.h>
void test(void)
{
atomic_int a;
int e;
_Bool b;
atomic_store(&a, 1);
e = 1;
b = atomic_compare_exchange_strong(&a, &e, 2);
assert(b);
assert(atomic_load(&a) == 2);
atomic_store(&a, 3);
e = 4;
b = atomic_compare_exchange_strong(&a, &e, 5);
assert(!b);
assert(atomic_load(&a) == 3);
}
Tested also on a NGMP board with a LEON4 processor.

During GEN_HELPER=1, these are actually stray top-level semi-colons
which are technically invalid ISO C, but GCC accepts as an extension.
If we added enough __extension__ markers that we could dare use
-Wpedantic, we'd see
warning: ISO C does not allow extra ‘;’ outside of a function
This will become a hard error in the next patch, wherein those ; will
appear in the middle of a data structure.
