c - I'm trying to interpret this IA32 assembly language code -

-

I have this IA32 assembly language code, I am trying to convert to regular c code. 

  .global FN. Type Fn, @functionfn: pushl% ebp #setup movl $ 1,% eax #setup 1 is in a movl% esp,% ebp #setup movl 8 (% ebp),% edx # pointer x is de sempel $ 1 In,% edx # (* x> 1) Jelly.4 .5: Imul% Adx,% ex subl $ 1,% edx cmpl $ 1,% edx jne.5 .l4: popl% ebp ret

The problem I am facing is deciding which type of comparison is going on. I do not know how the program is in the L5 cache. L5 seems to be because it has a comparison, because there is a comparison between it. I do not even know what is being returned because it seems that most of the work is% of ADX registrations, but does not return to% eax for the return.

What do I have so far: 

  int fn {}

It seems to me that this is a factual computing, ignoring the manipulation of the stack frame and as such, we leave it with:

< Pre movl $ 1,% eax #setup is in 1a

puts EX in 1 

  movl 8 (% ebp), % Edx # pointer is in XD

Recovers a parameter in ADX 

  emul% ADX,% eX

Adiak Multiplies EX by C, the result is inserted into the EX. 

  subl $ 1,% edx cmpl $ 1,% edx Jne .5

decreases ADX and if edx! Repeats = 1.

In other words, it is almost equivalent: 

  unsigned facts (unsigned input) {unsigned retal = 1; For (; input! = 1; - input) realval * = input; Return return; }

I need to type gt; & Gt; & Gt; Sqlalchemy import column, integer, string & gt; & Gt; & Gt; Class user (base): __tablename__ = 'users' id = column (integer, primary_key = true) name = column (string) absolute name = column (string) password = column (string) def __repr __ (self): return "& lt ; User (name = '% s', absolute name = '% s', password = '% s') & gt; "% (Self.name, self.fullname, self.password) After the problem I have typed the password = column (string) I hit twice and changed .... >> I then took everything back but then an error was thrown because the class already exists ... I am not completely sure how to fix it. How do I open that slip in the shell script and edit it (Add DF to DRR) The error thrown below: / user / giripeters / TFSQLLX / Lib / python2.7 / site-packages / sqlalchemy / ext / decla...

lua - HowTo create a fuel bar -

I would like to create a fuel bar (empty with full tank). When the user touches the screen, the fuel once Dairejh these is my code: lifeBar = display.newImage ( "fuel_bar1.png") lifeBar.anchorX = 0 lifeboats. ======================== Lifetime Y = 37 screens Group: The Insert function (called Laifbar) However, I fuel Kansmoshn (equivalent to "pressed" variable to reduce the fuel tank "true") Have used. When pressed == is true, it means that the user is touching the screen: processed (fuel) processed () if life & gt; 0 and pressed == true remains = life - life 1 Life = life =. Wide-1 remains Value.text = string.format ("% d", life) End of this This function is active as the entrance event: runtime: addEventListener ( "Antrfrem" fuel Snsadna) it is very well, but my question is: pressed variable each time 5 seconds (once = = True) How is it possible to reduce the vitality width? I tried to add it to my touch even...
