Since we do not plan to exit, use cpu_unwind_state_data
and extract exactly the data requested.
This is a bug fix, in that we no longer clobber dflag.
Consider:
l.j L2 // branch
l.mfspr r1, ppc // delay
L1: boom
L2: l.lwa r3, (r4)
Here, dflag would be set by cpu_restore_state (because that is the current
state of the cpu), but but not cleared by tb_stop on exiting the TB
(because DisasContext has recorded the current value as zero).
The next TB begins at L2 with dflag incorrectly set. If the load has a
tlb miss, then the exception will be delivered as per a delay slot:
with DSX set in the status register and PC decremented (delay slots
restart by re-executing the branch). This will cause the return from
interrupt to go to L1, and boom!

When registering helpers via FFI for TCI, the inner loop that iterates
parameters of the helper reuses (and thus pollutes) the same variable
used by the outer loop that iterates all helpers, thus made some helpers
unregistered.
Fix this logic error by using a dedicated temporary variable for the
inner loop.

Commit 8801ccd050 introduced a compilation failure with clang

1 error generated.
It's a false positive -- the compiler doesn't manage to figure out
that the error checks further up mean that there's no code path where
vdpa_device_fd isn't initialized. Put another way, the problem is
that we check "if (opts->has_vhostfd)" when in fact that condition
must always be true. A cleverer static analyser would probably warn
that we were checking an always-true condition.
Fix the compilation failure by removing the unnecessary if().

Since there's no support for exception handling in C, the try-catch
blocks have been deleted, and throw clauses are replaced. When a runtime
error happens, we're printing out the error message. Disassembling of
the current instruction interrupts. This behavior is achieved by adding
sigsetjmp() to discard further disassembling after the error message
prints and by adding the siglongjmp() function to imitate throwing an
error. The goal was to maintain the same output as it was.

The return type of typedef disassembly_function is changed to char *
instead of std::string. Therefore, for every particular
disassembly_function function signature is changed.
For example:
- static std::string ABS_D(uint64 instruction, img_address m_pc) {...}
is replaced with
- static char *ABS_D(uint64 instruction, img_address m_pc) {...}
Every helper function used to return std::string is changed to return
const char * or char *. Where the return value points to a static string
that the caller must not free, the return type is const char *. If a
function allocates memory and the caller is required to free it, the
return type is a char *. This applies to the following functions:
img_format, to_string, GPR, save_restore_list, FPR, etc.
Now that we replaced every std::string for const char * or char *, it is
possible to delete multiple versions of the img_format function. The
general version:
- static char *img_format(const char *format, ...) {...}
can handle all string formatting, so others have been deleted.
Where necessary, strings are dynamically allocated with g_strjoinv,
g_strdup, g_strdup_vprintf, and g_strdup_printf. Memory leaking will be
prevented later.
String concatenation in the save_restore_list() function is handled
using g_strjoinv() function instead of += operator.
The type of the "dis" parameter in the Disassemble function is changed
- from std::string &
- to char **
Without applying all of these changes, the nanomips disassembler may be
buildable but can't produce the appropriate output, so all of them are
made together.

Header file nanomips.h has been deleted for the nanomips disassembler to
stay consistent with the rest of the disassemblers which don't include

The following is moved from the nanomips.h to nanomips.cpp file:
- #include line
- typedefs
- enums
- definition of the Pool struct.
Header file nanomips.h will be deleted to be consistent with the rest of
the disas/ code.

NMD class has been deleted. The following methods are now declared as
static functions:
- public NMD::Disassemble method
- private NMD::Disassemble method
- private NMD::extract_op_code_value helper method
Also, the implementation of the print_insn_nanomips function and
nanomips_dis function is moved to the end of the nanomips.cpp file,
right after the implementation of the Disassemble function.

Pool tables are no longer declared as static fields of the NMD
class but as global static const variables. Pool struct is defined
outside of the class.
The NMD::Disassemble method is using the MAJOR Pool table variable, so
its implementation is moved to the end of the nanomips.cpp file,
right after the initialization of the MAJOR Pool table.

NMD class methods with the disassembly_function type like
NMD::ABS_D, NMD::ABS_S, etc. are removed from the class. They're now
declared global static functions. Therefore, typedef of the function
pointer, disassembly_function is defined outside of the class.
Now that disassembly_function type functions are not part of the NMD
class we can't access them using the this pointer. Thus, the use of
the this pointer has been deleted.

Helper methods from NMD class like NMD::renumber_registers,
NMD::decode_gpr_gpr4... etc. are removed from the class. They're now
declared global static functions.
Following helper methods have been deleted because they're not used by
the nanomips disassembler:
- NMD::encode_msbd_from_pos_and_size,
- NMD::encode_s_from_s_hi,
- NMD::neg_copy
Global functions used by those methods:
- nanomips_dis
- sign_extend
- extract_bits
have also been defined as static global functions.

We're deleting the m_pc field of the NMD class. It's now part of the
Dis_info struct that this patch introduces. Currently, the Dis_info
struct has just one field, m_pc, which we need for address calculation
in the ADDRESS function.
We're filling Dis_info at the entrance of the nanoMIPS disassembler.
I.e. print_insn_nanomips. Next, we're adding that information as an
argument wherever we need to.
Since NMD class now has no more fields, the NMD constructor is
also deleted.
