LLVM can also be built with gcc after version 7.5. [37] LLVM can also generate relocatable machine code at compile-time or link-time or even binary machine code at runtime. LLVM supports a language-independent instruction set and type system. [6] Each instruction is in static single assignment form (SSA), meaning that each variable (called a ...
The LLVM project originally intended to use GCC's front end. The GCC source code, however, is large and somewhat cumbersome; as one long-time GCC developer put it referring to LLVM, "Trying to make the hippo dance is not really a lot of fun". [17] Besides, Apple software uses Objective-C, which is a low priority for GCC developers.
LLVM bytecode: JavaScript: This allows running C/C++ codebases in a browser for example c2go [62] C: Go: Before the 1.5 release, the Go compiler was written in C. An automatic translator was developed to automatically convert the compiler codebase from C into Go.
Like GCC, LLVM also targets some IRs meant for direct distribution, including Google's PNaCl IR and SPIR. A further development within LLVM is the use of Multi-Level Intermediate Representation with the potential to generate code for different heterogeneous targets, and to combine the outputs of different compilers. [6]
GCC has been ported to more platforms and instruction set architectures than any other compiler, and is widely deployed as a tool in the development of both free and proprietary software. GCC is also available for many embedded systems, including ARM-based and Power ISA-based chips.

However, in LTO as implemented by the GNU Compiler Collection (GCC) and LLVM, the compiler is able to dump its intermediate representation (IR), i.e. GIMPLE bytecode or LLVM bitcode, respectively, so that all the different compilation units that will go to make up a single executable can be optimized as a single module when the link finally ...
