In practice, Clang is a drop-in replacement for GCC. [24] 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. [25]
Compilation time generally increased relative to Clang 4.0. Some benchmarks found some versions of GCC had better performance than some versions of Clang (AOCC included), and vice versa. In August 2019 Phoronix again benchmarked AOCC, now AOCC 2.0 against Clang 9 and GCC 9.1 and 10.0. [11]
Apple was a significant user of LLVM-GCC through Xcode 4.x (2013). [43] [44] 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.
...runtime performance of clang/LLVM output is sometimes worse than GCC's. GCC's compilation speeds are really slow, but runtime performance of binaries is generally (9/10 itw cases) better by 10+%. Phoronix this tests can back me up. "sometimes" suggests that it's like that in <50% cases.
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.

[7] Mozilla points out that the performance of natively compiled code is not a single measure but rather a range, with different native compilers (in this case Clang and GCC) delivering code of differing performance. "In fact, on some benchmarks, like Box2D, FASTA and copy, asm.js is as close or closer to Clang than Clang is to GCC. In one case ...
