riscv64-unknown-linux-gnu-gcc

riscv64-unknown-linux-gnu-gcc is a cross-compiler for the RISC-V architecture, targeting the Linux operating system. It is used to compile C/C++ code for RISC-V systems running Linux, enabling developers to create software that can run on RISC-V-based devices. The compiler is part of the RISC-V GNU toolchain, which also includes other tools such as binutils, libc, and gdb. The RISC-V architecture is an open-source, royalty-free instruction set architecture (ISA) that is gaining popularity in the embedded systems and IoT industries due to its flexibility, extensibility, and energy efficiency.
