What is the LLVM project?

What is the LLVM project?

The LLVM Project is a collection of modular and reusable compiler and toolchain technologies. Despite its name, LLVM has little to do with traditional virtual machines. The name “LLVM” itself is not an acronym; it is the full name of the project.

How do I write my pass in LLVM?

Writing an LLVM Pass

  1. The ImmutablePass class.
  2. The ModulePass class. The runOnModule method.
  3. The CallGraphSCCPass class. The doInitialization(CallGraph &) method.
  4. The FunctionPass class. The doInitialization(Module &) method.
  5. The LoopPass class.
  6. The RegionPass class.
  7. The MachineFunctionPass class.
  8. Pass registration.

What can I do with LLVM?

LLVM is a library that is used to construct, optimize and produce intermediate and/or binary machine code. LLVM can be used as a compiler framework, where you provide the “front end” (parser and lexer) and the “back end” (code that converts LLVM’s representation to actual machine code).

What language is LLVM written?

C++LLVM / Programming language

What is LLVM module?

An LLVM module is effectively a translation unit or a collection of translation units merged together.

What is LLC in LLVM?

The llc command compiles LLVM source inputs into assembly language for a specified architecture. The assembly language output can then be passed through a native assembler and linker to generate a native executable.

Which programming languages use LLVM?

What is LLVMContext?

This is an important class for using LLVM in a threaded context. It (opaquely) owns and manages the core “global” data of LLVM’s core infrastructure, including the type and constant uniquing tables. LLVMContext itself provides no locking guarantees, so you should be careful to have one context per thread.

What is LLI in LLVM?

DESCRIPTION. lli directly executes programs in LLVM bitcode format. It takes a program in LLVM bitcode format and executes it using a just-in-time compiler or an interpreter. lli is not an emulator. It will not execute IR of different architectures and it can only interpret (or JIT-compile) for the host architecture.

What assembler does LLVM use?

llvm-as is the LLVM assembler. It reads a file containing human-readable LLVM assembly language, translates it to LLVM bitcode, and writes the result into a file or to standard output. If filename is omitted or is – , then llvm-as reads its input from standard input.

What is Llvm module?

What does LLI stand for?

Leveled Literacy Intervention (LLI)
