Understanding of some assembly lines

Question

i have the following assembly lines:

....
LEA   EAX, DWORD PTR DS:[0x404212]
MOV   DWORD PTR SS:[EBP-0x3CC], EAX
PUSH  DWORD PTR SS:[EBP-0x3CC]
...
...
...
LEA   EAX, DWORD PTR DS:[0x404213]
MOV   DWORD PTR SS:[EBP-0x3D0], EAX
PUSH  DWORD PTR SS:[EBP-0x3D0]
...
...

So, I asked myself how I can that piece of code translate into a higher language like C? Or a pseudo C language?

But, for the the two blocks I have the following:

 UNKNOWNTYPE *eax_pointer_1;     //points to 00404212
 UNKNOWNTYPE *eax_pointer_2;     //points to 00404213

In ollydbg, I see that at the address 00404212 there is the following line :

ADD BYTE PTR DS:[EAX], DH

and at the address 00404213, there is:

XOR BYTE PTR DS:[EAX], AL

So my question would be : Is that a correct transformation? Have you some ideas how I can the instructions at 00404212 and 00404213 make part of my transformation into a pseudo-C language?

In ollydbg, I see that at the address 00404212 there is the following line:

ADD BYTE PTR DS:[EAX], DH

And, at the address 00404213, there is:

XOR BYTE PTR DS:[EAX], AL

I dont think those are code, rather variables, are they in a code/execute section ?

Answer 2

It looks like the address of something (maybe an array element) is being taken and that is being used to set up call frame for later use. Something very roughly like:

void f(void){
  void *x = &someMemory;
  void *y = &someMemory2;

  g(y,x);
}

caveat lector.
