Research direction

Reproduce the two calls shown for current_mlil[9] and current_function at address 0x984, then trace how each computes the stack-frame offset for the 'sp' register. Compare the results and add a focused regression check once the expected behavior is confirmed; done means both APIs return consistent values for this instruction.

Description

Component: Core Impact: Low 
>>> current_mlil[9].get_reg_value('sp')
<stack frame offset 0x0>
>>> current_function.get_reg_value_at(here, 'sp')
<stack frame offset -0xd0>
>>> hex(here)
'0x984'
>>> hex(current_mlil[9].address)
'0x984'
