This patchset converts the nanomips disassembler to plain C. C++ features
like class, std::string type, exception handling, and function overloading
have been removed and replaced with the equivalent C code.

Please see the discussion about why converting it here:

Since there's no namespace feature in C, namespace img has been replaced
with adding the prefix "img" to the namespace members.

Prefix "img" has been added to the function names of functions that used
to be wrapped in namespace img. Those are img::format() functions.
I.e. replaced img::format with the img_format.

Typedef address that used to belong to namespace img now is called
img_address.

Since you've removed the (unused) as_char() function here...

... you also might want to remove the comment that is using it here

Anyway, the patch looks fine to me, so:

Definitions of enums TABLE_ENTRY_TYPE and TABLE_ATTRIBUTE_TYPE are moved
out of the NMD class. The main goal is to remove NMD class completely.

Class fields have been replaced with the public static variables.
Therefore, there is no more need for a constructor. The main goal is to
remove NMD class completely.

This is not a viable solution, as it is not thread-safe.  You need to keep a struct and 
add it as an explicit argument where required.

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

Does that build in C? You are declaring 2 functions with the same name
but a different prototype... Shouldn't you squash patch #14 here which
rename these functions with the return value as suffix?

Ditto.

Up to the final patch, this is still C++, so I think it's still valid, isn't it?

NMD class methods with the conditional_function type like
NMD::ADDIU_32__cond, NMD::ADDIU_RS5__cond, etc. are removed from the NMD
class. They're now declared global static functions. Therefore, typedef
of the function pointer, conditional_function is defined outside of the
class.

Now that conditional_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.

QEMU C style is more like this:

                    if ((cond == NULL) || cond(op_code)) {

Please add a space before the returned type. I'd rather
prefix functions extracted from the NMD class with `nmd_`:

    typedef bool (*nmd_conditional_fn)(uint64 instruction);

But adding a prefix will also increase the size of the patches quite a bit 
(well, maybe not for this identifier here, but certainly for some other 
spots), so I think it's fair to keep it without prefix here, too. Just my 
0.02 €.

The typedef is moved from the header to the source file in patch #9,
so OK.

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.

Pool tables are no longer declared as static fields of the NMD
class but as global static variables.

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 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.

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.

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

The return type of typedef disassembly_function is changed to
const char * instead of std::string. Therefore, for every particular
disassembly_function function signature is changed.
For example:
- static std::string ABS_D(uint64 instruction) {...} is replaced with
- static const char *ABS_D(uint64 instruction) {...}

Every helper function used to return std::string is changed to return
const char *. This applies to 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 const char *img_format(const char *format, ...) {...}
can handle all string formatting, so others have been deleted.

Where necessary, strdup() is used to malloc string. Memory leaking needs
to be prevented, so matching free() calls will be added later.

Simple assignments like:
- x = "string"
are handled using the strcpy() function where needed.

String concatenation in the save_restore_list() function is handled
using strcat() function instead of += operator.

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.

Subject: [PATCH 12/20] disas/nanomips: Replace std::string type

The return type of typedef disassembly_function is changed to
const char * instead of std::string. Therefore, for every particular
disassembly_function function signature is changed.
For example:
- static std::string ABS_D(uint64 instruction) {...} is replaced with
- static const char *ABS_D(uint64 instruction) {...}

Every helper function used to return std::string is changed to return
const char *. This applies to 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 const char *img_format(const char *format, ...) {...}
can handle all string formatting, so others have been deleted.

Where necessary, strdup() is used to malloc string. Memory leaking needs
to be prevented, so matching free() calls will be added later.

Simple assignments like:
- x = "string"
are handled using the strcpy() function where needed.

String concatenation in the save_restore_list() function is handled
using strcat() function instead of += operator.

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.

If you're returning allocated memory, the return type could also be "char *" 
instead of "const char *" - that way you could get rid of a lot of casting 
in the next patch ("free((char *)....)").

Maybe it would also be better to switch to the functions from glib instead, 
you could avoid hard-coded array sizes that way. E.g. for this function:

static const char *to_string(img_address a)
{
     return g_strdup_printf("0x%" PRIx64, a);
}

See: https://docs.gtk.org/glib/func.strdup_printf.html

Using a hard-coded array first and doing a strdup() at the end looks weird 
... why don't you malloc() the str buffer right at the beginning of the 
function? (or use g_malloc instead to avoid
checking for NULL).

The free() function is called for every string allocated using the
strdup() function to prevent memory leaking.

The implementation of the several functions working with dynamically
allocated strings is slightly changed so we can free those strings.

Almost every disassembly_function returns the result of the img_format()
function, which returns a dynamically allocated string. To be able to
free that string for every disassembly_function, a strdup() call is
added for returning value of some disassembly functions like TLBGINV,
TLBGINVF, TLBGP, etc.

Subject: [PATCH 13/20] disas/nanomips: Add free() calls

The free() function is called for every string allocated using the
strdup() function to prevent memory leaking.

The implementation of the several functions working with dynamically
allocated strings is slightly changed so we can free those strings.

Almost every disassembly_function returns the result of the img_format()
function, which returns a dynamically allocated string. To be able to
free that string for every disassembly_function, a strdup() call is
added for returning value of some disassembly functions like TLBGINV,
TLBGINVF, TLBGP, etc.

When using glib, you could get rid of the free() here by declaring dis_str 
with g_autofree.

I really dislike the need of having these "(char *)" casts in the calls to 
free() everywhere.
IMHO, if a function allocated memory and the caller is required to free it, 
the memory belongs to the caller after the function has finished, so it 
would be better to return "char *" instead of "const char *" in these cases. 
"const char *" should be used in the cases where the return value points to 
static strings that the caller must not free.
(Apart from that, please consider to use g_autofree for the variables 
declaration everywhere you added a free() here ... that would make this 
patch way easier).

  Thomas

Renamed the following functions by adding a suffix:
- copy to copy_ui and copy_i
- IMMEDIATE to IMMEDIATE_UI and IMMEDIATE_I
Calls to copy and IMMEDIATE functions are replaced based on the type of
arguments.

Disassemble function that calls the other variant of it is deleted.
Where it is called, now we're directly calling the other implementation.

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.

Subject: [PATCH 15/20] disas/nanomips: Replace exception handling

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.

Now that everything has been converted to C code the nanomips.cpp file
