In practice, Clang is a drop-in replacement for GCC. [25] Clang's developers aim to reduce memory footprint and increase compiling speed compared to other compilers, such as GCC. In October 2007, they report that Clang compiled the Carbon libraries more than twice as fast as GCC, while using about one-sixth GCC's memory and disk space. [26]
Apple was a significant user of LLVM-GCC through Xcode 4.x (2013). [44] [45] This use of the GCC frontend was considered mostly a temporary measure, but with the advent of Clang and advantages of LLVM and Clang's modern and modular codebase (as well as compilation speed), is mostly obsolete.
Most BSD family operating systems also switched to GCC shortly after its release, although since then, FreeBSD and Apple macOS have moved to the Clang compiler, [10] largely due to licensing reasons. [ 11 ] [ 12 ] [ 13 ] GCC can also compile code for Windows , Android , iOS , Solaris , HP-UX , AIX and DOS .
Since both GCC and LLVM (clang) are able produce an IR from a variety of programming languages, link-time IPO can happen even across language boundaries. This is most commonly demonstrated with C and C++, [ 9 ] but LLVM makes it possible for Rust and all other LLVM-based compilers too.
GCC and Clang are two major C compilers popular today, both based on the C11 with updates including changes from later specifications such as C17. [ 29 ] [ 30 ] Any source code written only in standard C and without any hardware dependent assumptions is virtually guaranteed to compile correctly on any platform with a conforming C implementation.
MILEPOST GCC: interactive plugin-based open-source research compiler that combines the strength of GCC and the flexibility of the common Interactive Compilation Interface that transforms production compilers into interactive research toolsets.
However, GCC's nested functions, unlike blocks, must not be called after the containing scope has exited, as that would result in undefined behavior. GCC-style nested functions currently use dynamic creation of executable thunks on most architectures when taking the address of the nested function. On most architectures (including X86), these ...
The AMD Optimizing C/C++ Compiler (AOCC) is an optimizing C/C++ and Fortran compiler suite from AMD targeting 32-bit and 64-bit Linux platforms. [1] [2] It is a proprietary fork of LLVM + Clang with various additional patches to improve performance for AMD's Zen microarchitecture in Epyc, and Ryzen microprocessors.
