Hi,

Programming is new to me. I started reading the Flat Assembler Documentation as suggested in the FASM FAQ sticky. In the compiler overview [1.1], it states Flat Assembler is a fast Assembly language compiler for the x86 architecture processors, which does multiple passes to optimize the size generated machine code.

q] What does Multiple Passes mean?

q] What is Optimization?

q] How does Multiple Passes, optimize the size of the generated machine code?

Thanks

  • Multiple passes usually means evaluating something more than once (e.g., each line of source code is read several times), saving specific necessary information for later.

  • Optimization means to optimize (make optimal = make best). Optimus is the superlative form of the word "good" in Latin (bonus = good, melior = better).

  • Sometimes things are used before they are defined. In this case, you can only guess until you connect all the dots and figure out what everything means.

    a = b + 2


    We must wait until we know what b is defined as.

    Quote:

    b = 10*5


    b equals fifty, so now we know that a equals fifty two.

    P.S. I'm sure most people on this forum will be able to explain much, much better than me. Anyways, hope this tides you over until then. Smile
