how to call a function by aCC inline assembly

[Dennis Handly]

>still don't know what exactly the called function does to find the inputted parms.

You need to simulate and reverse engineer in your head what it does.

>can you please describe more details? till now, I can't find useful document of this.

7.1 Procedure Frames

>if I pass int, double, int, double by stack, how are they placed?
sp+0x20 -> int
sp+0x28 -> double
sp+0x30 -> int
sp+0x38 -> double

These would be parms 9 .. 12.  If you took the address of these in the callee, p1 .. p8 would be stored into sp-0x30 to sp+0x18.

The two int (4 byte) parms would be stored right justified:

sp+0x24 -> int
sp+0x34 -> int
