gcc - What exactly is LLVM? - Stack Overflow An LLVM-based compiler: This is a compiler built partially or completely with the LLVM infrastructure For example, a compiler might use LLVM for the frontend and backend but use GCC and GNU system libraries to perform the final link
What is the difference between clang (and LLVM) and gcc g++? LLVM is, perhaps, two things then LLVM-the-machine, which is the type system and instruction set, which is probably better referred to as "LLVM IR"; and LLVM-the-API, which is software for manipulating code in the LLVM IR, such as the LLVM JIT compiler, or perhaps the LLVM x86 machine code backend
c++ - LLVM what is it and how can i use it to cross platform . . . LLVM is, as its name says a low level virtual machine which have code generator If you want to compile to it, you can use either gcc front end or clang, which is c c++ compiler for LLVM which is still work in progress
How is GCC IR different from LLVM IR? - Stack Overflow Discussion of differences of back-end IRs (LLVM MachineIR and GCC RTL) and related codegen tools (LLVM Tablegen and GCC Machine Description) is an interesting and important topic but would make the answer several times larger I left out library-based design of LLVM vs monolithic design of GCC as this is separate from IR per se (although related)
c - How to make clang compile to llvm IR - Stack Overflow I want clang to compile my C C++ code to LLVM bitcode rather than a binary executable How can I achieve that? And if I have the LLVM bitcode, how can I further compile it to a binary executable? I
Dump IR after each LLVM optimization (each pass), both LLVM IR passes . . . Basically, I want to have an LLVM IR dump before and after each optimization pass Also, it can be useful to have all dumps of the AST from Clang and all phases of code generation (backend phases, Selection DAG, ISEL-SDNode, register allocation, and MCInsts)
What is LLVM and why is it so popular all of a sudden? [closed] LLVM is a collection of libraries built to support compiler development and related tasks Each library supports a particular component in a typical compiler pipeline (lexing, parsing, optimizations of a particular type, machine code generation for a particular architecture, etc )
