-//
-// This file declares the LTOCodeGenerator class.
-//
-//   LTO compilation consists of three phases: Pre-IPO, IPO and Post-IPO. 
-//
-//   The Pre-IPO phase compiles source code into bitcode file. The resulting
-// bitcode files, along with object files and libraries, will be fed to the
-// linker to through the IPO and Post-IPO phases. By using obj-file extension,
-// the resulting bitcode file disguises itself as an object file, and therefore
-// obviates the need of writing a special set of the make-rules only for LTO
-// compilation.
-//
-//   The IPO phase perform inter-procedural analyses and optimizations, and
-// the Post-IPO consists two sub-phases: intra-procedural scalar optimizations
-// (SOPT), and intra-procedural target-dependent code generator (CG).
-// 
-//   As of this writing, we don't separate IPO and the Post-IPO SOPT. They
-// are intermingled together, and are driven by a single pass manager (see
-// PassManagerBuilder::populateLTOPassManager()).
-// 
-//   The "LTOCodeGenerator" is the driver for the IPO and Post-IPO stages. 
-// The "CodeGenerator" here is bit confusing. Don't confuse the "CodeGenerator"
-// with the machine specific code generator.
