Low Level Virtual Machine (LLVM) is:
|
||
|
|
|
||
|
|
1. A compilation strategy 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), while remaining
|
||
|
|
transparent to developers and maintaining compatibility with existing
|
||
|
|
build scripts.
|
||
|
|
|
||
|
|
2. A virtual instruction set - LLVM is 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. This combination enables sophisticated
|
||
|
|
transformations on object code, while remaining light-weight enough to
|
||
|
|
be attached to the executable. This combination is key to allowing
|
||
|
|
link-time, run-time, and offline transformations.
|
||
|
|
|
||
|
|
3. A compiler infrastructure - LLVM is also a collection of source code that
|
||
|
|
implements the language and compilation strategy. The primary components
|
||
|
|
of the LLVM infrastructure are a GCC-based C & C++ front-end, a
|
||
|
|
link-time optimization framework with a growing set of global and
|
||
|
|
interprocedural analyses and transformations, static back-ends for many
|
||
|
|
popular (and some obscure) architectures, a back-end which emits portable
|
||
|
|
C code, and a Just-In-Time compilers for several architectures.
|
||
|
|
|
||
|
|
4. LLVM does not imply things that you would expect from a high-level
|
||
|
|
virtual machine. It does not require garbage collection or run-time code
|
||
|
|
generation (In fact, LLVM makes a great static compiler!). Note that
|
||
|
|
optional LLVM components can be used to build high-level virtual machines
|
||
|
|
and other systems that need these services."
