First, LLVM comes in two pieces. The first piece is the LLVM suite. This contains all of the tools, libraries, and header files needed to use the - low level virtual machine. It also contains a test suite that can be used - to test the LLVM tools and the GCC front end. + low level virtual machine. It contains an assembler, disassembler, + bytecode analyzer, and bytecode optimizer. It also contains a test suite + that can be used to test the LLVM tools and the GCC front end.
The second piece is the GCC front end. This component provides a version of GCC that compiles C and C++ code into LLVM bytecode. Currently, the @@ -76,133 +76,6 @@ development). Once compiled into LLVM bytecode, a program can be manipulated with the LLVM tools from the LLVM suite. - -

The remainder of this guide is meant to get you up and running with - LLVM and to give you some basic information about the LLVM environment. - The next section gives a short summary for those - who are already familiar with the system and want to get started as quickly - as possible.
