; This function reads a location that is probeDepth words beyond
|
|
; the current stack pointer. On intel platforms the stack grows
|
|
; downwards so this means reading from a location with a lesser address.
|
|
;
|
|
; The registers edi, esi, ebx are the registers defined to be preserved
|
|
; across function calls, so we do not use those.
