;# As you have already noticed, the compiler wants to align the stack
;# pointer on a 16 byte boundary before it pushes anything. That's
;# because certain instructions' memory access needs to be aligned
;# that way.
;# So in order to first save the original offset of esp (+4), it
;# executes the first instruction:
lea ecx,[esp+0x4]
;# Now alignment can happen. Without the prevIoUs insn the next one
;# would have made the original esp unrecoverable:
and esp,0xfffffff0
;# Next it pushes the return addresss and creates a stack frame. I
;# assume it Now wants to make the stack look like a normal
;# subroutine call:
push DWORD PTR [ecx-0x4]
push ebp
mov ebp,esp
;# Remember that ecx is still the only value that can restore the
;# original esp. Since ecx may be garbled by any subroutine calls,
;# it has to save it somewhere:
push ecx
