PCIe port 0 and 1 had link_up set as false previously,
that makes those two ports effectively useless. It can
be annoying for users to find that the device they plug
on those buses won't work at all.
As link_up is true by default, just don't set it again in
boston platform code.

Rather than registering the reset handler via a function which
appends the handler to a global list, prefer to implement it as

Back then, MIPSr6 was not supported (added in binutils commit

not possible to simply cherry-pick their changes, so fix it BEQZC /

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.
