Does Go use GCC or LLVM?
There are three Go compiler implementations supported by the Go team.
These are gc , the default compiler, gccgo , which uses the GCC back end, and a somewhat less mature gollvm , which uses the LLVM infrastructure..
Is LLVM better than GCC?
GCC supports more traditional languages than Clang and LLVM, such as Ada, Fortran, and Go.
GCC supports more less-popular architectures, and supported RISC-V earlier than Clang and LLVM.
GCC supports more language extensions and more assembly language features than Clang and 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..
Is LLVM C or C++?
LLVM is written in C++ and is designed for compile-time, link-time, runtime, and "idle-time" optimization..
What architectures are supported by LLVM?
LLVM MC's integrated assembler supports most LLVM targets, including IA-32, x86-64, ARM, and ARM64.
For some targets, including the various MIPS instruction sets, integrated assembly support is usable but still in the beta stage..
What are the advantages of LLVM IR?
LLVM allows code to be compiled statically, as it is under the traditional GCC system, or left for late-compiling from the IR to machine code via just-in-time compilation (JIT), similar to Java..
What compiler does LLVM use?
How A LLVM Compiler Works.
On the front end, the LLVM compiler infrastructure uses clang — a compiler for programming languages C, C++ and CUDA — to turn source code into an interim format..
What is LLVM in compiler design?
LLVM is an acronym that stands for low level virtual machine.
It also refers to a compiling technology called the LLVM project, which is a collection of modular and reusable compiler and toolchain technologies..
What languages are made with LLVM?
LLVM is written in C++ and is designed for compile-time, link-time, run-time, and idle-time optimization.
Popular languages with compilers that use LLVM include Fortran, Haskell, Julia, Kotlin, Lua, Objective-C, OpenGL, Rust, and Swift..
What programming languages are made with LLVM?
Apple's Swift language uses LLVM as its compiler framework, and Rust uses it as a core component of the Rust toolchain.
Many compilers use LLVM including Clang, the C/C++ compiler (hence the name, “C-lang”).
Mono, the .
NET implementation, has an option to compile to native code using an LLVM back end..

Why should I use LLVM?
LLVM helps build new computer languages and improve existing languages.
It automates many of the difficult and unpleasant tasks involved in language creation, such as porting the outputted code to multiple platforms and architectures..
- A compilation phase in which LLVM bytecode is optimized.
Refers to any one of the five compilation phases that that llvmc supports.
The five phases are: preprocessing, translation, optimization, assembly, linking. - The LLVM Compiler Infrastructure
The LLVM project has multiple components.
The core of the project is itself called "LLVM".
This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. - There are three Go compiler implementations supported by the Go team.
These are gc , the default compiler, gccgo , which uses the GCC back end, and a somewhat less mature gollvm , which uses the LLVM infrastructure. - Using something like LLVM when designing a compiler has a lot of advantages, since tons of work can be saved by using an existing optimizer and code generation for a variety of platforms.
Even large, popular languages like Rust and Julia use LLVM, and LLVM implementations of languages like Go and Kotlin exist.
