<div dir="ltr"><div><div><div>Hi,<br></div>I intend to write an optimization using LLVM. But before doing that I felt like understanding the tools. I wrote a hello world program to be compiled and executed. But then one of the tutorials suggested using Clang, an other said dragonegg, a third suggested using llvm-gcc. I am confused as to which one to use. Can some one help me in<br>
<br></div><div>1. What are the differences between these three?<br></div><div>2. Which one best serves my ultimate purpose of developing an machine independent optimizer using LLVM?<br></div>3. Can someone give me step-by-step instructions to compile and execute this simple hello world C program?<br>
