There is no direct IA32 assembler instruction for 'if' or 'while'.

The assembler instructions to use are of the following form:

  compare ...               // result of compare is stored somewhere
  if ( result ) goto Label  // conditional jumps
  goto Label                // unconditional jumps

Example: if (x >= y) goto L2

  cmpl y,x
  jge L2

Note the order of the operands of cmpl!!!
