a compiler cache. It acts as a caching pre-processor to C/C++ compilers. Caching previous compilations and detecting when the same compilation is being done again. (needs GCC or similar)
a program that examines source code and reports possible security weaknesses (``flaws'') sorted by risk level. It's very useful for quickly finding and removing at least some potential security problems before a program is widely released to the public.
designed to enable effective program optimization across the entire lifetime of a program. LLVM supports effective optimization at compile time, link-time (particularly interprocedural), run-time and offline (i.e., after software is installed), provides a low-level object code representation that uses simple RISC-like instructions, but provides rich, language-independent, type information and dataflow (SSA) information about operands.
a build configuration tool. Describe your C, C++, or C# software project using a simple, easy to read syntax and let Premake generate the project files for Visual Studio, GNU Make, Code::Blocks, CodeLite, SharpDevelop, or MonoDevelop.
