Подключение к питону происходит с помощью:
import idc
import idautils
import idaapi
У меня есть наработки некоторые, возможно что-то пригодится.
import idc
import idaapi
class Func(object):
def __init__(self):
self.reg_value = re.compile(r'')
self.stack_view = []
self.level = 1
def range_reverse(self, start, stop):
for i in FuncItems(stop):
if start > i >= stop:
yield i
def run(self):
if self.stack_view:
for j in self.stack_view:
current_function = idaapi.get_func(j)
level = "-" * self.level
print("{} Jump into -> 0x{}".format(level, hex(current_function.startEA)[2:].replace("L", "").upper()))
for j in [i for i in self.range_reverse(current_function.endEA, current_function.startEA)]:
print("{} 0x{} -- {}".format(level, hex(j)[2:].replace("L", "").upper(), idc.GetDisasm(j)))
self.level += 1
else:
print "Please input addresses to stack view buffer"
pass
if __name__ == '__main__':
f = Func()
f.stack_view = [0x214FE, 0x20F30, 0x214E0, 0x13F00]
f.run()
В выводе получим

Надо будет поправить пару строк, чтобы выводилась не функция целиком, а как при трассировке:
for j in [i for i in self.range_reverse(current_function.endEA, current_function.startEA)]:
