2022-10-31disas/nanomips: Remove function overloadingMilica Lazarevic1-7/+1
Disassemble function that calls the other variant of it is deleted. Where it is called, now we're directly calling the other implementation.

2022-10-31disas/nanomips: Prevent memory leakingMilica Lazarevic1-45/+51
g_autofree attribute is added for every dynamically allocated string to prevent memory leaking. The implementation of the several functions that work with dynamically allocated strings is slightly changed so we can add those attributes.

2022-10-31disas/nanomips: Remove CPR functionMilica Lazarevic1-65/+45
CPR functions has been removed. Before this patch, we'd been calling img_format twice, the first time through the CPR function to get an appropriate string and the second time to print that formatted string. There's no more need for that. Therefore, calls to CPR are removed, and now we're directly printing "CP" and integer value instead.

2022-10-31disas/nanomips: Replace std::string typeMilica Lazarevic1-2439/+2337
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.

There are no known users of this CPU anymore, and there are no binaries available online which could be used for regression tests, so the code has likely completely bit-rotten already. It's been marked as deprecated since two releases now and nobody spoke up that there is still a need to keep it, thus let's remove it now.

2021-04-17osdep: protect qemu/osdep.h with extern "C"Paolo Bonzini2-2/+2
System headers may include templates if compiled with a C++ compiler, which cause the compiler to complain if qemu/osdep.h is included within a C++ source file's 'extern "C"' block. Add an 'extern "C"' block directly to qemu/osdep.h, so that system headers can be kept out of it. There is a stray declaration early in qemu/osdep.h, which needs to be special cased. Add a definition in qemu/compiler.h to make it look nice. config-host.h, CONFIG_TARGET, exec/poison.h and qemu/compiler.h are included outside the 'extern "C"' block; that is not an issue because they consist entirely of preprocessor directives. This allows us to move the include of osdep.h in our two C++ source files outside the extern "C" block they were previously using for it, which in turn means that they compile successfully against newer versions of glib which insist that glib.h is *not* inside an extern "C" block.

This is caused by passing the wrong value to the read_memory_func(). The intention is that at this point in the loop the 'cap_buf' buffer already contains 'csize' bytes of data for the instruction at guest addr 'pc', and we want to read in an extra 'tsize' bytes. Those extra bytes are therefore at 'pc + csize', not 'pc'. On the first time through the loop 'csize' happens to be zero, so the initial read of 32 bytes into cap_buf is correct and as long as the disassembly never needs to read more data we return the correct information. Use the correct guest address in the call to read_memory_func().
