What is LLVM frontend?
LLVM is a set of compiler and toolchain technologies that can be used to develop a front end for any programming language and a back end for any instruction set architecture.
What is LLVM Python?
llvmpy is a Python wrapper around the llvm C++ library which allows simple access to compiler tools. It can be used for a lot of things, but here are some ideas: dynamically create LLVM IR for linking with LLVM IR produced by CLANG or dragonegg. build machine code dynamically using LLVM execution engine.
Is Clang and LLVM same?
LLVM is a backend compiler meant to build compilers on top of it. It deals with optimizations and production of code adapted to the target architecture. CLang is a front end which parses C, C++ and Objective C code and translates it into a representation suitable for LLVM.
Is LLVM better than GCC?
While LLVM and GCC both support a wide variety languages and libraries, they are licensed and developed differently. LLVM libraries are licensed more liberally and GCC has more restrictions for its reuse. When it comes to performance differences, GCC has been considered superior in the past.
Why is LLVM so good?
What makes it so popular is that its modular design allows its functionality to be adapted and reused very easily.
Will LLVM replace GCC?
Long answer: Depends, it’s a matter of adoption as well as other factors. For example, Apple uses LLVM (and Clang) for pretty much everything including building the kernel (previously built using GCC), bootloader and the userspace.
Is LLVM faster than GCC?
While LLVM’s Clang C/C++ compiler was traditionally known for its faster build speeds than GCC, in recent releases of GCC the build speeds have improved and in some areas LLVM/Clang has slowed down with further optimization passes and other work added to its growing code-base.
Is LLVM worth learning?
It has been a really good decision for me to use llvm because it allowed me to quickly get up and running and focus on things that mattered to me. I didn’t have to think too much about memory layout and machine specific stuff. Plus now I can use my language on arm which is great.
What programming language does llvmlite use?
Most of llvmlite uses the LLVM C API which is small but very stable (low maintenance when changing LLVM version). The binding is not a Python C-extension, but a plain DLL accessed using ctypes (no need to wrestle with Python’s compiler requirements and C++ 11 compatibility).
Is there a LLVM API for Python?
The old llvmpy binding exposes a lot of LLVM APIs but the mapping of C++-style memory management to Python is error prone. Numba and many JIT compilers do not need a full LLVM API. Only the IR builder, optimizer, and JIT compiler APIs are necessary.
What is the difference between llvmlite and llvmpy?
llvmlite is quite faster than llvmpy’s thanks to a much simpler architeture (the Numba test suite is twice faster than it was). The llvmlite.llvmpy namespace provides a minimal llvmpy compatibility layer. llvmlite works with Python 3.7 and greater. As of version 0.37.0, llvmlite requires LLVM 11.x.x on all architectures
Does Numba need the LLVM API?
The old llvmpy binding exposes a lot of LLVM APIs but the mapping of C++-style memory management to Python is error prone. Numba and many JIT compilers do not need a full LLVM API. Only the IR builder, optimizer, and JIT compiler APIs are necessary. The IR builder is pure Python code and decoupled from LLVM’s frequently-changing C++ APIs.
