GCC and clang requires explicit target_clones labels in the code to "clone" functions, [20] while ICC does so automatically (under the command-line option /Qax). The Rust programming language also supports FMV. The setup is similar to GCC and Clang in that the code defines what instruction sets to compile for, but cloning is manually done via ...
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]

While both projects followed each other's changes closely, EGCS development proved considerably more vigorous, so much so that the FSF officially halted development on their GCC 2.x compiler, blessed EGCS as the official version of GCC, and appointed the EGCS project as the GCC maintainers in April 1999.
Clang – The free Clang project includes a static analyzer.As of version 3.2, this analyzer is included in Xcode. [14]Infer – Developed by an engineering team at Facebook with open-source contributors.
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 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 usually ported to other ...
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.
