%description
LLVM is a compiler 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 since 2000 at the University of Illinois and Apple. It
currently supports compilation of C and C++ programs, using front-ends
derived from GCC 4.0.1. A new front-end for the C family of languages
is in development. The compiler infrastructure includes mirror sets of
programming tools as well as libraries with equivalent functionality.

%description -l pl.UTF-8
LLVM to infrastruktura kompilatora zaprojektowana do optymalizacji
czasu kompilowania, linkowania, działania i bezczynności programów w
dowolnych językach programowania. Jest napisana w C++, rozwijana od
roku 2000 przez Uniwersytet w Illinois i Apple. Aktualnie obsługuje
kompilację programów w C i C++ przy użyciu frontendów wywodzących się
z GCC 4.0.1. W trakcie tworzenia jest nowy frontend do języków z
rodziny C. Infrastruktura kompilatora zawiera lustrzane zestawy
narzędzi programistycznych oraz biblioteki z odpowiadającą narzędziom
funkcjonalnością.
