What is LLVM value?
Detailed Description. LLVM Value Representation. This is a very important LLVM class. It is the base class of all values computed by a program that may be used as operands to other values. Value is the super class of other important classes such as Instruction and Function.
What are LLVM intrinsics?
An intrinsic function is a function built in to the compiler. The compiler knows how to best implement the functionality in the most optimized way for these functions and replaces with a set of machine instruction for a particular backend.
What is an LLVM backend?
The backend of LLVM features a target-independent code generator that may create output for several types of target CPUs — including X86, PowerPC, ARM, and SPARC. The backend may also be used to generate code targeted at SPUs of the Cell processor or GPUs to support the execution of compute kernels.
What is LLVM in iOS?
The LLVM compiler is the next-generation compiler, introduced in Xcode 3.2 for Snow Leopard, based on the open source LLVM.org project. The LLVM.org project employs a unique approach of building compiler technologies as a set of libraries.
Why is it called LLVM?
The name LLVM was originally an initialism for Low Level Virtual Machine. However, the LLVM project evolved into an umbrella project that has little relationship to what most current developers think of as a virtual machine.
How do you find the argument of a function in LLVM?
You can use Function::getArgumentList() method to get a list of function’s arguments. Then, you traverse it with iterators – ArgumentListType::begin() and ArgumentListType::end() . UPD: The current way of iterating over arguments is arg_begin() / arg_end() / args() methods.
Is LLVM open source?
Latest LLVM Release! 25 March 2022: LLVM 14.0. 0 is now available for download! LLVM is publicly available under an open source License.
What is a Bitcast?
Bitcast is a community-driven marketplace to educate software developers through video.
What is LLVM written in?
C++LLVM / Programming language
Why does Apple use LLVM?
Today, Apple uses LLVM to build its desktop and notebook operating system, Mac OS X, as well as its iOS operating system, used by smartphones and tablets. The tool is at the heart of the Apple Xcode software that outside developers use to build applications for all these machines.
Does Apple use LLVM?
Multiple technology groups within Apple are active contributors within the LLVM.org community, and they use LLVM technology to make Apple platforms faster and more secure.
What is LLVM in C++?
LLVM is designed around a language-independent intermediate representation (IR) that serves as a portable, high-level assembly language that can be optimized with a variety of transformations over multiple passes. LLVM is written in C++ and is designed for compile-time, link-time, run-time, and “idle-time” optimization.
Will LLVM version 8 be the last release under the license?
However, LLVM version 8 will be the last release under that license as LLVM is moving to a new license structure. You can find more details about this in the developer’s policy. If you are interested in LLVM, we strongly encourage you to sign up for the LLVM announcements mailing list.
What is the LLVM MC subproject?
The LLVM machine code (MC) subproject is LLVM’s framework for translating machine instructions between textual forms and machine code.
What is the license for the LLVM project?
The LLVM project includes an implementation of the C++ Standard Library called libc++, dual-licensed under the MIT License and the UIUC license. Since v9.0.0, it was relicensed to the Apache License 2.0 with LLVM Exceptions.
