GCC

The industry standard compiler suite for C, C++, and Fortran: essential for building the modern Linux stack.

GCC (GNU Compiler Collection) is the backbone of the open source world: it compiles the Linux kernel and thousands of critical software packages. It supports a wide array of frontends (including C, C++, and Ada) and targets architectures from x86_64 to RISC-V. Developers rely on its mature optimization passes (-O2 and -O3) to squeeze performance out of hardware. Version 13.x maintains this lead by refining C++23 support and improving static analysis tools to catch memory leaks early.
