+               LLVM Compiler Infrastructure -- Release 1.0
+                         http://llvm.cs.uiuc.edu (*)
+ 
+ We are pleased to announce the public release of the LLVM Compiler
+ Infrastructure under a non-restrictive open source license.
+ 
+ WHAT IS LLVM?
+   LLVM is a new infrastructure designed for compile-time, link-time, runtime, 
+   and "idle-time" optimization of programs from arbitrary programming 
+   languages.  LLVM is written in C++ and has been developed over the past 3 
+   years at the University of Illinois.  It currently supports compilation of 
+   C and C++ programs, using front-ends derived from GCC 3.4.  New front-ends 
+   are being written for Java bytecode and O-Caml.
+ 
+ WHOM MIGHT THIS RELEASE BE USEFUL?
+   o  Compiler researchers interested in compile-time, link-time
+      (interprocedural) and runtime transformations for C and C++ programs.
+   o  Virtual machine researchers/developers interested in a portable,
+      language-independent instruction set and compilation framework.
+   o  Architecture researchers interested in compiler/hardware techniques.
+   o  Security researchers interested in static analysis or instrumentation.
+   o  Instructors (or anyone else) interested in a system for quick
+      prototyping of compiler transformations.
+ 
+ HOW LONG DOES IT TAKE TO GET STARTED WITH LLVM?
+ 
+   We have found that new users can install LLVM and write their first LLVM
+   pass in hours, and start sophisticated projects using LLVM within days.
+ 
+ WHY IS LLVM USEFUL?
+   LLVM uses a low-level, RISC-like, language-independent representation to
+   analyze and optimize programs.  Key features include explicit control
+   flow, dataflow (SSA), and a language-independent type system that can
+   capture the _operational behavior_ of high-level languages.  The LLVM
+   representation is low-level enough to represent arbitrary application and
+   system code, yet is powerful enough to support aggressive "high-level"
+   transformations.  The LLVM infrastructure uses this representation to
+   allow these optimizations to occur at compile-time, link-time and runtime.
+ 
+ WHAT IS INCLUDED IN THIS RELEASE?
+   Release 1.0 is intended to be a fully functional release of our compiler
+   system for C and C++.  As such, it includes the following:
+   o  Front-ends for C and C++ based on GCC 3.4, supporting the full
+      ANSI-standard C and C++ languages, plus many GCC extensions.
+   o  A wide range of global scalar optimizations
+   o  A link-time interprocedural optimization framework, with a rich
+      set of analyses and transformations, including sophisticated
+      whole-program pointer analysis and call graph construction.
+   o  Native code generators for x86 and Sparc
+   o  A JIT code generation system for x86 and Sparc
+   o  A C back-end, useful for testing and to support other targets
+   o  A test framework with a number of benchmark codes and some applications
+   o  APIs and debugging tools to simplify rapid development
+ 
+ WHAT IS NOT INCLUDED IN THIS RELEASE?
+   Some components are not yet implemented in LLVM, including array dependence
+   analysis, dependence-based transformations, profiling support, and a
+   trace-based dynamic optimization system.  The native code generators are
+   not yet competitive with vendor compilers in performance.
+ 
+ HOW DO I GET IT?
+   Please see: http://llvm.cs.uiuc.edu/releases (*)
