Aarch64 analysis (idasdk misses)

[yeggor]

I will give here some examples of usage idasdk that works for x86 (32, 64) but does not work for Aarch64.

Changing the function prototype doesn't work either.
Consider the following example:

unsigned __int64 __fastcall sub_1150(__int64 a1, __int64 a2)

We want to change the type of argument a2 to EFI_SYSTEM_TABLE * and name of argument a2 to SystemTable.
Normally we would have done it this way:

import ida_typeinf


func_addr = 0x1150
func_tif = ida_typeinf.tinfo_t()
ida_typeinf.guess_tinfo(func_tif, func_addr)
funcdata = ida_typeinf.func_type_data_t()
func_tif.get_func_details(funcdata)
# change funcdata[1].type and funcdata[1].name, then call apply_tinfo()
# but len(funcdata) == 0
assert len(funcdata) > 1
# Traceback (most recent call last):
#   File "<string>", line 1, in <module>
# AssertionError

FYI: I preloaded uefi.til and uefi64.til, applying all types to global/local variables works.
