Go Goes Loong: Exploring Go Programming Language Support for LoongArch64(New feature in 1.19)

Loong64 (also known as LoongArch64) is the 64-bit version of the LoongArch instruction set architecture (ISA), developed by the Chinese company Loongson. It’s designed for general-purpose computing in desktops, laptops, and servers.

Key points about Loong64:

• Developer: Loongson Technology Corporation Limited
• Purpose: Primarily for general-purpose computing
• Inspiration: While inspired by MIPS64, it has evolved into a distinct ISA.
• Open Source: Loongson has made LoongArch an open standard.
• Software Support:
• Compilers: GCC and LLVM
• Operating Systems: Linux (Loongson’s own distribution and Debian)
• Languages: Go, Java, JavaScript, .NET, and others are being ported.
• Hardware: Loongson’s 3A5000 series CPUs are based on LoongArch.

Significance:

• China’s independent CPU architecture: LoongArch reduces reliance on foreign technologies.
• Growing ecosystem: Increasing software support and openness attract developers and manufacturers.
