     Args:
         node (BasicBlock): The basic block containing instructions that define variables and their usage.
         expression (Expression): The expression to be matched against the `pattern`.
-        pattern (tuple or Callable or str): The pattern used for matching.

             The innermost (first) entry in a pattern is either:
               - A string representing a variable name to be matched exactly.
               - A function (Callable) that takes an `expression` and returns `True` if the expression matches some criteria, `False` otherwise.

             For example:
-              - (self._match_r14, 0x10) 
-              - ((("gsbase", 0), -4), 0x8)

+              - ((("gsbase", 0), -4), 0x8)
             The latter pattern represents an expression equivalent to *(*(*(gsbase+0) - 4) + 8).
-        instr_num (int, optional): The instruction number to start searching backwards for variable definitions.
