With roughly 15 million lines of code in 2019, GCC is one of the largest free programs in existence. [4] It has played an important role in the growth of free software, as both a tool and an example. When it was first released in 1987 by Richard Stallman, GCC 1.0 was named the GNU C Compiler since it only handled the C programming language. [1]
To give compiler vendors greater freedom, the C++ standards committee decided not to dictate the implementation of name mangling, exception handling, and other implementation-specific features. The downside of this decision is that object code produced by different compilers is expected to be incompatible.
mingw-w64.org. Mingw-w64 is a free and open-source suite of developments tools that generate Portable Executable (PE) binaries for Microsoft Windows. It was forked in 2005–2010 from MinGW (Minimalist GNU for Windows). Mingw-w64 includes a port of the GNU Compiler Collection (GCC), GNU Binutils for Windows (assembler, linker, archive manager ...
Intel C++ Compiler Classic is available for Windows, Linux, and macOS and supports compiling C and C++ source, targeting Intel IA-32, Intel 64 (x86-64), Core, Xeon, and Xeon Scalable processors. [ 5 ] It supports the Microsoft Visual Studio and Eclipse IDE development environments. Intel C++ Compiler Classic supports threading via Intel oneAPI ...
A code sanitizer is a programming tool that detects bugs in the form of undefined or suspicious behavior by a compiler inserting instrumentation code at runtime. The class of tools was first introduced by Google's AddressSanitizer (or ASan) of 2012, which uses directly mapped shadow memory to detect memory corruption such as buffer overflows or accesses to a dangling pointer (use-after-free).
clang.llvm.org. Clang (/ ˈkleɪŋ /) [ 6 ] is a compiler front end for the programming languages C, C++, Objective-C, Objective-C++, and the software frameworks OpenMP, [ 7 ] OpenCL, RenderScript, CUDA, SYCL, and HIP. [ 8 ] It acts as a drop-in replacement for the GNU Compiler Collection (GCC), supporting most of its compiling flags and ...
Profile-guided optimization (PGO, sometimes pronounced as pogo[1]), also known as profile-directed feedback (PDF), [2] and feedback-directed optimization (FDO) [3] is a compiler optimization technique in computer programming that uses profiling to improve program runtime performance.
Loop unrolling. Loop unrolling, also known as loop unwinding, is a loop transformation technique that attempts to optimize a program's execution speed at the expense of its binary size, which is an approach known as space–time tradeoff. The transformation can be undertaken manually by the programmer or by an optimizing compiler.
