Low Level Virtual Machine (LLVM) Compiler Infrastructure
 
Low Level Virtual Machine (LLVM) Compiler Infrastructure
 +
 +
The LLVM compiler system for C and C++ includes the following:
 +
* Front-ends for C, C++, Objective-C, Fortran, etc based on the GCC 4.2 parsers. They support the ANSI-standard C and C++ languages to the same degree that GCC supports them. Additionally, many GCC extensions are supported.
 +
* A stable implementation of the LLVM instruction set, which serves as both the online and offline code representation, together with assembly (ASCII) and bytecode (binary) readers and writers, and a verifier.
 +
* A powerful pass-management system that automatically sequences passes (including analysis, transformation, and code-generation passes) based on their dependences, and pipelines them for efficiency.
 +
* A wide range of global scalar optimizations.
 +
* A link-time interprocedural optimization framework with a rich set of analyses and transformations, including sophisticated whole-program pointer analysis, call graph construction, and support for profile-guided optimizations.
 +
* An easily retargettable code generator, which currently supports X86, X86-64, PowerPC, PowerPC-64, ARM, Thumb, SPARC, Alpha, and IA-64.
 +
* A Just-In-Time (JIT) code generation system, which currently supports X86, X86-64, PowerPC and PowerPC-64.
 +
* Support for generating DWARF debugging information.
 +
* A C back-end useful for testing and for generating native code on targets other than the ones listed above.
 +
* A profiling system similar to gprof.
 +
* A test framework with a number of benchmark codes and applications.
 +
* APIs and debugging tools to simplify rapid development of LLVM components.
