Clang becomes default compiler for Android [52] (and later only compiler supported by Android NDK [53]). 13 March 2017 Clang 4.0.0 released: 26 July 2017: Clang becomes default compiler in OpenBSD 6.2 on amd64/i386. [54] 7 September 2017 Clang 5.0.0 released: 19 January 2018: Clang becomes default compiler in OpenBSD 6.3 on arm. [55] 5 March 2018
In May 2010, the GCC steering committee decided to allow use of a C++ compiler to compile GCC. [55] The compiler was intended to be written mostly in C plus a subset of features from C++. In particular, this was decided so that GCC's developers could use the destructors and generics features of C++.
C compilers do not name mangle symbols in the way that C++ compilers do. [20] Depending on the compiler and architecture, it also may be the case that calling conventions differ between the two languages. For these reasons, for C++ code to call a C function foo(), the C++ code must prototype foo() with extern "C".

The main parts of the C++ compiler clang were written in a subset of C++ that can be compiled by both g++ and Microsoft Visual C++. Advanced features are written with some GCC extensions. The compiler for X is cross compiled from another architecture where there exists a compiler for X; this is how compilers for C are
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.
Java's division and modulus operators are well defined to truncate to zero. C++ (pre-C++11) does not specify whether or not these operators truncate to zero or "truncate to -infinity". -3/2 will always be -1 in Java and C++11, but a C++03 compiler may return either -1 or -2, depending on the platform.
