Example representation:

High Address
+------------------+
|  Parameter 2     |   <- rbp + 24 (0x18)
+------------------+
|  Parameter 1     |   <- rbp + 16 ()
+------------------+
|  Return Address  |   <- rbp + 8
+------------------+
|  Saved rbp       |   <- rbp
+------------------+
|  First Local     |   <- rbp - 8
+------------------+
|  Second Local    |   <- rbp - 16 ()
+------------------+
