BTW, both GCC and Clang/LLVM have several internal specialized C/C++ code generators. In other words, a real-world optimizing compiler has to be a complex piece of software. Look also into the CompCert proved C compiler, and the Frama-C static analyzer, which care about more formal semantics of C.Īnd optimizations are a long-tail phenomenon: implementing a few simple optimizations is easy, but they won't make a compiler competitive! You need to implement a lot of different optimizations, and to organize and combine them cleverly, to get a real-world compiler that is competitive. The C++ specific parts of GCC are about 20% of the compiler.Īlso, C (or C++) is so widely used that people expect their code to be compilable even when it does not exactly follow the official standards, which do not define precisely enough the semantics of the language (so each compiler may have its own interpretation of it). Hence most optimizing C compilers are also able to compile some other languages, like C++, Fortran, D. In particular, making a C++ compiler is not much harder than making a C compiler: parsing C++ and transforming it into some internal code representation is complex (because the C++ specification is complex), but is well understood, but the optimization parts are even more complex (inside GCC: the middle-end optimizations, source-language and target-processor neutral, form the majority of the compiler, with the rest being balanced between front-ends for several languages and back-ends for several processors). The complexity of a good C compiler is not in the parsing phase! Notice that both GCC and Clang are optimizing some "source language-neutral" code representation (Gimple for GCC, LLVM for Clang). See the C is not a low level language (Your computer is not a fast PDP-11) paper by David Chisnall.įew people are using naive non-optimizing C compilers like tinycc or nwcc, since they produce code which is several times slower than what optimizing compilers can give.Ĭoding an optimizing compiler is difficult. Today's x86 processors are not like i386 processors of the previous century, even if both are able to run the same machine code. Today, you need a real C compiler to be an optimizing compiler, notably because C is no longer a language close to the hardware, because current processors are incredibly complex ( out-of-order, pipelined, superscalar, with complex caches & TLB, hence needing instruction scheduling, etc.). that it actually is closer to C++ than Scheme)?
Do users simply have a very skewed idea about what complexity group it falls in (i.e. Why? Is implementing C so hard? It isn't C++.

Whereas the announcement of a new (unfinished) C compiler aiming at verification actually sees some pretty negative responses, and veteran implementations struggle to get enough contributors to even catch up to C99. Even something like SML has more "serious" implementations to choose between than C. Scheme and Forth - other small languages that are beloved by their fans for it - probably have more compilers than actual users. Very few actually seem to be open-source.

Half of the members of this list are historical footnotes most of the rest are very specialized and still don't actually implement the full language. There are a handful of others, far too obscure for the average person to name and almost universally not bothering to support a recent language version (or often even a well-defined language subset, just "a subset"). Thinking about it for a few seconds you'll probably remember Intel exists as well. On the desktop, there are (realistically) two: GCC and Clang. It's beloved by its users, it's so widely ported that being able to run C is to many the informal definition of a platform, and is praised by its fans for being a "small" language with a relatively clean set of features. It accounts for a huge proportion of existing code and continues to be used for a vast amount of new code. C is one of the most widely-used languages in the world.
