<DIV><!--AID_SENDTO_BEGIN-->Hi Guys,</DIV>


<DIV>    I am really a fresh man on compiler. I want to make a 


compiler that transform C-like language into assemble form, as the the same as 


Pixie's or Aqsis's RenderMan Shading Language compiler, just like this,</DIV>

<DIV>    Where should I begin, I have read Mr.Lattner's 


Kaleidoscope Tutorial, But How can I transform AST to the IR, optimize, then 


output assemble code ?</DIV>


<DIV>    Thanks very much. I wish I do not post in wrong 


place.</DIV>
